For those concerned about human-caused climate change, electrical vehicles and the batteries that their engines derive stored energy from are a key innovation. These zero emissions platforms stand to potentially replace more than a billion internal combustion engines — each dumping about three tons of greenhouse gasses into the atmosphere every year. Moreover, the powerful batteries in these cars can be used to store electricity generated by renewable sources. Making clean energy available 24/7 despite hours of darkness and lulls in the wind periodically sapping generation.
(In this National Renewable Energy Laboratory study, the most rapid carbon emissions reductions were achieved in scenarios where large-scale EV deployment was combined with wholesale replacement of coal, oil, and gas fired electricity generation with renewable sources like wind and solar.)
Recognizing the climate-saving potential of this clean tech, nations have pledged to rapidly transition vehicle fleets away from fossil fuel burning automobiles. Leaders of this revolutionary move include China, India, France, Germany, the Netherlands, and Britain.
The U.S. is also presently a leader in EV innovation — primarily due to efforts by California, a handful of states, and locally based clean energy giants like Tesla. However, U.S. leadership in this crucial new industry is presently threatened by the Trump Administration which is seeking to remove incentives for EV adoption while also undermining the ability of states like California to set clean car goals.
(With numerous countries, states and cities planning to ban fossil fuel based vehicles, the Trump Administration’s proposed policies to disincentivize EVs would put the U.S. at a competitive disadvantage. Image source: Commons.)
Such moves could rightly be called myopic as the global electrical vehicle market last year grew to 1.2 million and will likely hit near 2 million in 2018. So EV incentives in states like California aren’t just good for the environment, they’re good for U.S. competitiveness even as they benefit the larger economy. By the early 2020s, if Trump succeeds in undercutting the U.S. clean car market, around 5 million EVs will be sold per year even as U.S. automakers will be faced with the prospect of dwindling fossil fuel vehicle sales. A combination that may, once again, threaten bankruptcy for a key U.S. industry.
That said, despite ominous moves by Trump, the U.S. EV market presently continues to grow apace.
Tesla Model 3 Leads U.S. EV Sales
During January of 2018, approximately 12,000 EVs were sold. This beats out January of 2017 by about 1,000 cars to hit a new record for the U.S. market. And topping January’s sales is Tesla’s flagship Model 3. In all, about 1,875 of these clean cars were sold on the U.S. market last month according to Inside EVs. That’s about 80 percent growth from December sales and probably represents a total production of between 2,000 and 2,500 cars for the month.
(With 500,000 reservations, the all-electric, zero emissions Tesla Model 3 is probably the most desired car produced by an American automaker within the last 40 years. Can Tesla satisfactorily meet this demand by swiftly scaling production of high-quality versions? If it does, it will rapidly rocket to the top of the automotive world. Image source: Tesla.)
Model 3 is thus still steadily moving up the S curve according to this recent Inside EVs report. It is not, however, yet anywhere near target production volumes of 5,000 to 10,000 vehicles per week (which it now plans to meet by June). Nor is it in a position to hope to fulfill an unprecedented 500,000 pre-orders before 2019. Tesla thus still appears to be facing some production bottlenecks. But they appear to be steadily clearing even as the Model 3 line continues to ramp up. And at this point, it is notable that the Model 3 is now the best-selling EV in the U.S. We are likely to see continued progress with around 2,400 to 4,000 Model 3s sold during February. Ensuring that the Model 3 remains a top contender for the #1 EV sales spot for the foreseeable future.
2018 Nissan Leaf Enters U.S. Market with Potential to Surprise
Other top clean car sellers during January included Chevy with its Bolt (1,177) and Volt (713) offerings, Toyota’s Prius Prime (1,496), Honda’s Clarity (853), and Tesla’s Model X (700) and S (800).
(The 2018 Nissan Leaf ain’t as sexy as the Tesla Model 3. But it’s no slacker either — having already racked up numerous awards and tens of thousands of sales around the globe, this EV is now starting to enter the U.S. market. With a 150 mile range, a 30,000 dollar price point, and a jump in horsepower, this car has the potential to surprise during 2018. Image source: Commons.)
Nissan also released its new longer range Leaf in January. But low initial rates of production resulted in only 150 sold. This vehicle will be one to watch as Nissan has a track record for both producing and selling Leafs in high volumes. The Leaf has good reviews and a considerably expanded range, horsepower and other capabilities. It also comes in at a price about 5,000 dollars lower than the higher performance luxury Model 3. So it’s not surprising that the car has already racked up 14,000 pre-orders in the U.S.
Overall EV sales in the U.S. near 200,000 represented about 3 percent of the 2017 market. During 2018, we should expect the U.S. EV market share to grow to between 280,000 and 400,000. This growth will primarily be dependent on new higher performance, lower cost Model 3, Leaf, and Bolt sales. But detrimental policy moves by Trump or his Republican allies in Congress may negatively and unexpectedly impact this key emerging market.
FEB 5 UPDATE: Tesla Model 3 Sales Projections For January Now Range Between 1875 and 3,000
In lieu of actual numbers coming out of Tesla itself, two firms have lately been producing reliable numbers based on analysis of factory output, VIN numbers, and employee statements — Inside EVs and Clean Technica.
This weekend, Clean Technica put out its own estimate in which total numbers of Model 3s, Model Ss, and Model Xs sold were considerably higher than Inside EVs estimates at 3,000, 2,300, and 2,200 respectively. If Clean Technica’s numbers are correct, then the Model 3 is much further up the S curve than we thought earlier. In addition, the larger Model S and X estimates would be enough, if they bear out, to push total U.S. EV sales to over 16,000 for January.
Clean Technica’s perspective is one of more rapid growth. But either estimate shows both growth and progress. And they probably provide a decent bracket between the more conservative and aggressive estimate ranges. We’ll see who ends up revising their numbers over the coming days and weeks. But overall, this is cautious good news for EV and clean energy enthusiasts.

It’s gone, due to climate change. We view our cities, states and nations as eternal, as they usually are compared to our lifetimes. But when you live at the time of such state changes where abandonment occurs, what do you face?

To the untrained eye, you see the USA with some clouds. But look closer…. there is a lack of snow cover / ice cover in the continental US. I understand folks are glad it is mild, and driving is easy. But…..
That snow & ice is meant to melt slowly, recharging aquifers as well as providing moisture to the upper layers of soil. This is essential for farming, as that late winter, early spring snow cover helps stave off the droughts that one would face in August.
A system has been in place which we built a civilization around, temperatures are low and we accumulate surface based pending moisture (snow, ice). The temp rises slowly, it melts slowly seeping into the soil. We draw on that later in the year.
Now we do not accrue that pending moisture the same (amount or extent). And when it melts, the temps climb quicker so it runs off as opposed to slow absorption.
What that shot tells me is unless something happens, the Midwest will have wilting crops come summer (unless we squeeze the aquifers further). And as some years are good / bad for this water system, the bad will become more prevalent.
That will be another peril to our civilization.

Friday, February 2nd 2018
http://mynews4.com/on-your-side/snow-drought-in-the-sierra-nevada-mountains
“he Sierra Nevada Mountains are officially in a snow drought, receiving less snow this year than what is normal.

“Back in the day there has always been fluctuating snow levels in the sierra. There’s always been warm storms…There has been rain at lake level as far back as you can remember…But over the past four years we’ve seen snow droughts occur over all the last four seasons in some way shape or form.”
A staggering statistic as our climate continues to change, and this year has been unique Hatchett says,
“This year has been quiet interesting because it’s really highlighted what we are calling ‘all of the above’… All the different kinds of mechanisms that can get us into snow drought we’ve been seeing this year.”
We are currently on pace with the 2015 year, which is not good because research has suggested- 2015 was the lowest snow pack in the sierra dating back 500 years.
Snow droughts have been increasing in recent history, and although 2017 was one for the record books… We still experienced a type of snow drought. We saw heavy rain wash away snow in the early 2017 snow season.
Reno, NV (News 4 & Fox 11) — The Sierra Nevada Mountains are officially in a snow drought, receiving less snow this year than what is normal.

The Tahoe area snow pack is currently at 25-30 percent of the long term average.
However thanks to last year’s record snow our reservoirs are sitting high.
So our water supply should be okay as we go into the summer, but we won’t be making any significant deposit into our water bank this year.
But McEvoy explains we don’t know what spring weather lies ahead and it’s not atypical to see a “Miracle March” boost Sierra snow pack,….”

January 25th, 2018
https://www.abqjournal.com/1124388/a-dry-winter-leaves-new-mexico-thirsty.html
“…More than 93 percent of New Mexico is experiencing drought conditions, according to the U.S. Department of Agriculture’s drought monitor map, released Thursday.
Of that 93 percent, about 60 percent is categorized as severe drought, nearly 34 percent as moderate drought and less than 6.5 percent is classified as abnormally dry.
Last year at this time, only 2.5 percent of the state was considered to be in severe drought and less than 9.5 percent was considered abnormally dry – but that was not a typical year for New Mexico, which recently has had long dry periods….
The visible impact is that snow is well below normal for every basin that affects New Mexico and southern Colorado, Fontenot said.
For example, the Rio Chama Basin is 33 percent of normal; the Pecos Basin is 8 percent of normal; the Gila River Basin is 13 percent of normal; the Sangre de Cristo Mountains are 26 percent of normal; and the headwaters for the Rio Grande in Colorado are 37 percent of normal…..
New Mexico would need to get precipitation about 215 percent of normal just to get to normal in the upper Rio Grande, and 270 percent of normal on the lower Rio Grande.
In other words, “the switch would have to be turned back on, and it would have to be a fire hose.”
Unless drought conditions turn around, said Matt Rau, fire staff officer for the Cibola National Forest and Grasslands, “our prediction is for an early onset to fire season across the majority of New Mexico, particularly the central and south, and a potential for increased size of fires and more intense fires.”
When monsoon rains in New Mexico are abundant, the moisture results in a prodigious growth of grass and brush, “which translates to having a lot of available fire-carrying fuels to burn.” But the moisture in the growth and in the soil helps to moderate what fires we do have, Rau said…..”

ENVIRONMENTAL ACTIVIST BILL McKibben is known for writing grim volumes like The End of Nature, widely regarded as the first book about climate change. But his latest outing, Radio Free Vermont, is a major departure, a humorous novel about a fugitive radio host who agitates for Vermont to secede from the United States.
“When Mr. Trump was elected, it seemed like the last thing the world probably needed was another one of my dire nonfiction books about the trouble we’re in,” McKibben says in Episode 293 of the Geek’s Guide to the Galaxy podcast. “It seemed like if I was ever going to publish something funny, that would be the year when it might be useful to do it.”

Kibben on secession:
“I don’t think it’s going to be Vermont that disappears from the Union first. We’re an old state—all you’d have to do is threaten to cut off our Social Security and I think we’d capitulate. But I increasingly wonder if California is in it for the long haul or not—California and with it Washington and Oregon. I mean, California is the fifth-largest economy in the world taken on its own—it’s Germany—and it dominates the fields that the world most prizes right now, like technology. And I have no idea what benefit it really gets from being part of the United States at this point. It seems to me entirely plausible that you could think up events that would cause the good people of the Golden State to say, ‘Huh, you know maybe we could go this alone.’”

Birds drawn to bushes with mismatched stick insects stuck around to eat other residents, such as caterpillars and beetles, stripping some plants clean. “That this evolutionary force can cause local extinction is striking,” says Farkas, an ecologist at the University of New Mexico in Albuquerque. “It affects the entire community.” All this happened because of an out-of-place evolutionary trait.”

If you go on the Top Gear website (just hold your nose!), and look at the comments on Tesla stories you will find there is surprisingly widespread acceptance of EV’s future dominance. Even the anoraks know it is coming very soon.
Commercial vehicles are driven by the bottom line, and have a short but busy life, so I think they will switch quite quickly (maybe 5-8 years here in the UK ) for the vast majority of the market, especially as diesel is so deeply unfashionable for air quality reasons.
When it comes to passenger vehicles it will be the uncertainties on resale values on non-electric vehicles that kill them off. Diesel is dying on its feet (down as much as 30% year-on year here in the uk!) because everyone knows that one bought now might well be punished in the future. Uncertainty isn’t sexy.
Lets hope it can be the decade-ish, as Jeremy points out, it has happened before. I think you will have to be very brave to buy anything with an ICE, as a private buyer, past the mid-2020’s, but no doubt there will be a few.
In the US I think it will be a little slower due to greater distances involved, but only by a few years.

‘The Next Big Volcano Could Briefly Cool Earth. NASA Wants to Be Ready.’
Feb. 1, 2018
“A quarter-century ago, Pinatubo, a volcano in the Philippines, blew its top in a big way: It spewed a cubic mile of rock and ash and 20 million tons of sulfur dioxide gas into the atmosphere. The gas spread around the world and combined with water vapor to make aerosols, tiny droplets that reflected some sunlight away from the Earth. As a result, average global temperatures dropped by about one degree Fahrenheit for several years.
Powerful volcanic eruptions like Pinatubo’s in 1991 are one of the biggest natural influences on climate. So NASA researchers and other scientists are planning a rapid-response program to study the next big one.
But the climate impact of a Pinatubo-size eruption is also a natural analog of an idea that has existed on the fringes of science for years: geoengineering, or intervening in the atmosphere to deliberately cool the planet….
NASA officials play down the benefits to the study of geoengineering of a volcano-research program. Geoengineering has long had an outlaw image among much of the scientific community, viewed as risky last-resort measures to solve climate problems that would be better dealt with by cutting greenhouse gas emissions. Even discussing geoengineering concepts has long been considered taboo among many scientists.

With the state election there coming up in March, the Labor Premier has again teamed up with Tesla, this time to deliver a 250MW virtual power plant (the world’s largest), by supplying solar panels and batteries free of charge to at least 50,000 households, slashing their electricity bills by an estimated 30%. Given this is being rolled out to state-owned public housing, the savings will be going to the families who need it most.
The opposition has already pledged means-tested grants averaging $2,500 to facilitate the installation of batteries in 40,000 homes.

““Sanctions, anyone?” taunted RT, the Kremlin-controlled television network, in its report on the successful delivery of Russian natural gas to Boston Harbor on Sunday. Despite US efforts to hold Russia accountable for its war in Ukraine and illegal annexation of Crimea, one of the companies sanctioned by the Obama administration overcame those obstacles with a symbolic flourish, by delivering its very first liquefied natural gas shipment to the United States……
….the Gaselys, a ship whose cargo included Russian gas, chugged into Everett to fill cold-weather energy demand that the Commonwealth chooses not to meet with domestic natural gas.
Distrigas, the firm that imported that liquefied natural gas, said the transaction wasn’t prohibited, because the restrictions apply only to the company that exported it from its gas fields in Siberia, not to the liquefied natural gas itself.”

“…The majority owner of the Yamal plant is a Russian company called Novatek, whose shareholders include an ally of Vladimir Putin, Gennady Timchenko. The US Treasury initially imposed sanctions that prohibited US companies from providing new financing to Novatek and another Russian energy firm in 2014, in response to what the agency had described as Russia’s destabilization of eastern Ukraine and its annexation of Crimea.
Since these particular sanctions involve just the money that Novatek could access, energy industry experts said they do not prevent Western companies from buying the gas produced at its Yamal plant.
“The company that developed the project was sanctioned, but the gas itself was not sanctioned,” explained James Henderson, director of natural gas research at the Oxford Institute for Energy Studies in the United Kingdom….
…“This transaction is compliant with all US trade laws,” she added. “There are no imposed sanctions on LNG or oil cargoes that are partially or totally sourced from Russia. The only sanctions against Yamal related to financing of construction . . . not purchasing of fuel.””

“…
The high temperature could reach 81 degrees on Sunday in downtown Los Angeles, cooling to 75 on Monday and Tuesday before potentially spiking up into the low 80s again Wednesday and Thursday, said National Weather Service weather specialist Stuart Seto.
That’s above the average — 68 degrees — for this time of year downtown, Seto said…..
….And, of course, Los Angeles has barely seen any rain.
The weather service’s climate prediction center, which issues three-month outlooks for precipitation and temperature, doesn’t have particularly good news. For February, March and April, the center is forecasting lower-than-average precipitation and hotter-than-average temperatures for Southern California.
“We’re about halfway through the rain season, so we’ve only got February and March, and they better be a miracle,” said climatologist Bill Patzert. “If they’re not, we just back-flipped into the drought again.”
The culprit has been a recurring high-pressure system over the West. “It’s been a hot summer, a hot fall, and even now in the midwinter. We’re talking mid-80s at the end of January? That’s unheard of,” Patzert said.
The broiling January was part of what experts call a troubling theme. It was California’s hottest summer on record. October and November were the hottest in 122 years of record-keeping for Southern California.
“The heat … is pretty extraordinary,” UCLA climate scientist Daniel Swain said earlier this week. “Coastal California is susceptible to midwinter heat spells, but this is a particularly extreme example — to the point where we are breaking records.””

Ancient Stone Carvings Show a Comet Swarm Hitting Earth Around 10,950 BCE
Around the time civilisation changed forever.
Researchers have translated famous ancient symbols in a temple in Turkey, and they tell the story of a devastating comet impact more than 13,000 years ago.
Cross-checking the event with computer simulations of the Solar System around that time, researchers suggest that the carvings could describe a comet impact that occurred around 10,950 BCE – about the same time a mini ice age started that changed civilisation forever.
This mini ice age, known as the Younger Dryas, lasted around 1,000 years, and it’s considered a crucial period for humanity because it was around that time agriculture and the first Neolithic civilisations arose – potentially in response to the new colder climates. The period has also been linked to the extinction of the woolly mammoth.
“I think this research, along with the recent finding of a widespread platinum anomaly across the North American continent virtually seal the case in favour of [a Younger Dryas comet impact],” lead researcher Martin Sweatman told Sarah Knapton from The Telegraph.
“It appears Gobekli Tepe was, among other things, an observatory for monitoring the night sky,” Sweatman told the Press Association.
“One of its pillars seems to have served as a memorial to this devastating event – probably the worst day in history since the end of the Ice Age.”
The Gobekli Tepe is thought to have been built around 9,000 BCE – roughly 6,000 years before Stonehenge – but the symbols on the pillar date the event to around 2,000 years before that.

A Recent Ice Age Was Triggered by a Firestorm Bigger Than The One That Killed The Dinosaurs
In a hugely detailed and comprehensive new study, researchers have painted a picture of how around a tenth of Earth’s surface suddenly became covered in roaring fires at a point some 12,800 years ago.
The firestorm rivals the one that wiped out the dinosaurs, and it was caused by fragments of a comet that would have measured around 100 kilometres (62 miles) across.
As dust clouds smothered the Earth, it kicked off a mini ice age that kept the planet cool for another thousand years, just as it was emerging from 100,000 years of being covered in glaciers. Once the fires burned out, life could start again, according to the international team of scientists.
“The hypothesis is that a large comet fragmented and the chunks impacted the Earth, causing this disaster,” says one of the team, Adrian Melott from the University of Kansas.
“A number of different chemical signatures – carbon dioxide, nitrate, ammonia and others – all seem to indicate that an astonishing 10 percent of the Earth’s land surface, or about 10 million square kilometres [3.86 million square miles], was consumed by fires.”
To peer back into the burning fires and shock waves of this major event, a large number of geochemical and isotopic markers were measured from more than 170 sites across the world, involving a team of 24 scientists.
One of the pieces of analysis carried out was on patterns in pollen levels, which suggested pine forests were suddenly burned off to be replaced by poplar trees – a species specialising in covering barren ground, as you might get when your planet has been hit by a series of massive fireballs.
In fact parts of the comet that disintegrated in space are still likely to be floating around parts of our Solar System 13,000 years later.
High concentrations of platinum – often found in asteroids and comets – and high levels of dust were also noted in the samples analysed by the researchers, alongside increased concentrations of combustion aerosols you would expect to see if a lot of biomass was burning: ammonium, nitrate, and others.
Plants died off, food sources would have been scarce, and the previously retreating glaciers began to advance again, say the researchers. Human culture would have had to adapt to the harsher conditions, with populations declining as a result.
“Computations suggest that the impact would have depleted the ozone layer, causing increases in skin cancer and other negative health effects,” says Melott.
The team thinks such a widespread impact of comet fragments, and the ensuing firestorm, is responsible for that extra bit of cooling known as the Younger Dryas period. This relatively brief blip in the planet’s temperature has sometimes been put down to changing ocean currents.

“lead researcher Martin Sweatman told Sarah Knapton from The Telegraph.”
Oh, yeah. The Telegraph. Ok. Definitely a credible, trusted, responsible news source.
Dr. Martin Sweatman, University of Edinburgh’s School of Engineering.
Yep; sure. Engineering is the new Archeology.
And now, a word from the actual archeologists, on-site.
“Recently a (peer-reviewed) paper published by M. Sweatman and D. Tsikritsis, two researchers of the University of Edinburgh’s School of Engineering, has made headlines, suggesting that the Göbekli Tepe enclosures actually were space observatories and that some of the reliefs depict a catastrophic cosmic event…
…(this whole ‘Younger Dryas Impact’ hypothesis [external link] actually is disputed itself [external link], so making Göbekli Tepe a ‘smoking gun’ in this argument should absolutely ask for a closer look)….
…we were looking into the new study with quite some interest, too. After all it is a new and fascinating interpretation. However, upon closer inspection we as excavators of this important site would like to raise a few points which may challenge this interpretation in our point of view:
1. There still is quite a significant probability that the older circular enclosures of Göbekli Tepe’s Layer III actually were subterranean buildings – possibly even covered by roof constructions. This then somehow would limit their usability as actual observatories a bit.
2. Even if we assume that the night sky 12,000 years ago looked exactly like today’s, the question at hand would be whether a prehistoric hunter really would have put together the very same asterisms and constellations we recognise today (most of them going back to ancient Egyptian, Babylonian, and Greek scholars and descriptions)?
3. Contrary to the article’s premise the unearthed features at Göbekli Tepe are not shrouded in mystery. Published over the last years and decades, there is ample scientific literature available which unfortunately did not find its way into the study. The specific animals depicted in each enclosure’s iconography for instance seems to follow a certain intention, emphasizing different species in different enclosures. A purely substitutional interpretation ignores these more subtle but significant details. This also can be demonstrated for instance with the headless man on the shaft of Pillar 43, interpreted as symbol of death and mass extinction in the paper – however silently omitting the emphasised phallus in the same depiction which somehow contradicts the lifeless notion and implies a much more complex narrative behind these reliefs. There are even more reliefs on both narrow sides of P43 which went conpletely uncommented here.
4. It also seems a bit arbitrary to base this interpretation (and all its consequences as described in the paper) on what seems to be some randomly selected pillars and their iconography (the interpretation thus not covering “much of the symbolism of Göbekli Tepe” as stated in the paper, but merely the tip of that iceberg). In the meantime more than 60 monumental T-pillars could have been unearthed in the older Layer III – many of these showing similar reliefs of animals and abstract symbols, a few even as complex as Pillar 43 (like Pillar 56 or Pillar 66 in enclosure H, for example). And it does not end there: the same iconography is prominently known also from other find groups like stone vessels, shaft straighteners, and plaquettes – not only from Göbekli Tepe, but a variety of contemporary sites in the wider vicinity.
So, with all due respect for the work and effort the Edinburgh colleagues obviously put into their research and this publication, there still are – at least from our perspective as excavators of this important site – some points worth a detailed discussion. A more thorough exchange with the excavation team could have clarified many of these concerns.

“Our reservations, which are not meant to silence any further archaeoastronomic discussion for Göbekli Tepe at all but rather comment on a number of discrepances we see in the interpretation, are summed up here:”
“Meanwhile both authors of the orginal study replied to our response (same issue of MAA, see link above), stressing that “… given the statistical basis o[f] [their] interpretation, any interpretation inconsistent with [theirs] is very likely to be incorrect.” (Sweatman and Tsikritsis, Comment, MAA 17(2), 66). Admittedly though, we still would like to express our doubt that human creativity really can be treated as a statistical case solely.”

“….a more elaborate reply with further arguments and references which, in our opinion, challenge the interpretation and add more context to the paper’s discussion of Göbekli Tepe’s iconography in the light of the early Neolithic in Upper Mesopotamia. The editors of Mediterranean Archaeology and Archaeometry kindly agreed to publish our response in the same journal as the original article by Sweatman and Tsikritsis…..”
Comments on both of these tepetelegrams pieces are worth a look for anyone curious about the veracity of this claim.
e.g. “It is very unfortunate that people with little knowledge of the archaeology of Göbekli Tepe can somehow get their absurd “alternative facts” and non-sequiturs published in what claims to be a legitimate academic journal. Incidentally, the article does nothing for the reputation of the journal, its editorial staff, and its supposedly rigorous peer-review process. Such fantastic imaginations attract journalists, but I was very surprised to see that the magazine New Scientist, which has a very wide readership, published a short piece about the article in Mediterranean Archaeology and Archaeoastronomy. The story was credited to (anonymous) staff and the Press Association. So I suspect that the story is being promoted by the Press Association, which means that it will appear widely in newspapers around the world. Suspiciously, the New Scientist piece includes a direct quote from the lead author, Martin Sweatman. My guess is that the “lead author” is busy promoting his article – which is already listed as one of his “scientific” research publications on his university web-page. I am embarrassed that such poor scholarship is associated with the name of the University of Edinburgh, where I have served as an archaeologist.”
From the comments section, on-site researcher, Jens Notroff.
“We observed severe flaws in the line and logic of argumentation in one particular article and see no reason to connect Göbekli Tepe to the hypothetical Younger Dryas Impact Event. We made that clear in a response to that article. ”

Frank, that’s absolutely not true. The actual researchers at Göbekli Tepe even note that, as I’d c’n’p-ed above, even using the word “disputed”.
““”(this whole ‘Younger Dryas Impact’ hypothesis [external link] actually is disputed itself [external link], so making Göbekli Tepe a ‘smoking gun’ in this argument should absolutely ask for a closer look).”
There isn’t concensus on that Younger Dryas theory, not at all.
https://en.wikipedia.org/wiki/Younger_Dryas_impact_hypothesis#Criticism
“A study of Paleoindian demography found no evidence of a population decline among the Paleoindians at 12,900 ± 100 BP, which was inconsistent with predictions of an impact event.[29] They suggested that the hypothesis would probably need to be revised.[30][31] There is also no evidence of continent-wide wildfires at any time during terminal Pleistocene deglaciation,[32] though there is evidence that most larger wildfires had a human origin,[32] which calls into question the origin of the “black mat.”[33] Iridium, magnetic minerals, microspherules, carbon, and nanodiamonds are all subject to differing interpretations as to their nature and origin, and may be explained in many cases by purely terrestrial or non-catastrophic factors.[34]
If it is assumed that the hypothesis supposes that all effects of the putative impact on Earth’s biota would have been brief, all extinctions caused by the impact should have occurred simultaneously. However, there is much evidence that the megafaunal extinctions that occurred across northern Eurasia, North America and South America at the end of the Pleistocene were not synchronous. The extinctions in South America appear to have occurred at least 400 years after the extinctions in North America.[35][36][37] The extinction of woolly mammoths in Siberia also appears to have occurred later than in North America.[35] A greater disparity in extinction timings is apparent in island megafaunal extinctions that lagged nearby continental extinctions by thousands of years; examples include the survival of woolly mammoths on Wrangel Island, Russia, until 3700 BP,[35][36][38] and the survival of ground sloths in the Antilles,[39] the Caribbean, until 4700 cal BP.[35] The Australian megafaunal extinctions occurred approximately 30,000 years earlier than the hypothetical Younger Dryas event.[40]
The megafaunal extinction pattern observed in North America poses a problem for the bolide impact scenario, since it raises the question why large mammals should be preferentially exterminated over small mammals or other vertebrates.[41] Additionally, some extant megafaunal species such as bison and Brown bear seem to have been little affected by the extinction event, while the environmental devastation caused by a bolide impact would not be expected to discriminate.[35] Also, it appears that there was collapse in North American megafaunal population from 14,800 to 13,700 BP, well before the date of the hypothetical extraterrestrial impact,[42] possibly from anthropogenic activities, including hunting.[17]….
etc….”

‘How Bill Gates aims to clean up the planet
It’s a simple idea: strip CO2 from the air and use it to produce carbon-neutral fuel. But can it work on an industrial scale? ‘
4 Feb 2018
https://www.theguardian.com/environment/2018/feb/04/carbon-emissions-negative-emissions-technologies-capture-storage-bill-gates
“It’s nothing much to look at, but the tangle of pipes, pumps, tanks, reactors, chimneys and ducts on a messy industrial estate outside the logging town of Squamish in western Canada could just provide the fix to stop the world tipping into runaway climate change and substitute dwindling supplies of conventional fuel.
It could also make Harvard superstar physicist David Keith, Microsoft co-founder Bill Gates and oil sands magnate Norman Murray Edwards more money than they could ever dream of.
The idea is grandiose yet simple: decarbonise the global economy by extracting global-warming carbon dioxide (CO2) straight from the air, using arrays of giant fans and patented chemical whizzery; and then use the gas to make clean, carbon-neutral synthetic diesel and petrol to drive the world’s ships, planes and trucks.
The hope is that the combination of direct air capture (DAC), water electrolysis and fuels synthesis used to produce liquid hydrocarbon fuels can be made to work at a global scale, for little more than it costs to extract and sell fossil fuel today. This would revolutionise the world’s transport industry, which emits nearly one-third of total climate-changing emissions. It would be the equivalent of mechanising photosynthesis…….
…..Meanwhile, 4,500 miles away, in a large blue shed on a small industrial estate in the South Yorkshire coalfield outside Sheffield, the UK Carbon Capture and Storage Research Centre (UKCCSRC) is experimenting with other ways to produce negative emissions.
Known as Beccs (bioenergy with carbon capture and storage), this negative emissions technology is seen as vital if the UK is to meet its long-term climate target of an 80% cut in emissions at 1990 levels by 2050, according to UKCCSRC director Professor Jon Gibbins. The plan, he says, is to capture emissions from clusters of major industries, such as refineries and steelworks in places like Teesside, to reduce the costs of transporting and storing it underground.
“Direct air capture is no substitute for using conventional CCS,” says Gibbins. “Cutting emissions from existing sources at the scale of millions of tonnes a year, to stop the CO2 getting into the air in the first place, is the first priority……”

https://www.cnn.com/2018/02/05/africa/cape-town-day-zero-intl/index.html
“Cape Town officials pushed back their projections for “Day Zero” — the day the South African city’s taps are expected to run dry — from April 16 to May 11, citing a decline in agricultural water use. …
“Capetonians must continue reducing consumption if we are to avoid Day Zero. There has not been any significant decline in urban usage. All Capetonians must therefore continue to use no more than 50 liters (around 13 gallons) per person per day to help stretch our dwindling supplies,” the executive deputy mayor added….”
“An expansive area of high pressure situated in the Atlantic Ocean is acting as a barrier to these weather systems,” CNN meteorologist Derek Van Dam says. “As this high-pressure system strengthens and expands, it pushes rainfall away from the Western Cape.” “

‘2 bust for allegedly trying to smuggle water to Western Cape illegally’
2018-02-01
https://www.news24.com/SouthAfrica/News/2-bust-for-allegedly-trying-to-smuggle-water-to-western-cape-illegally-20180201
“Two people were caught red-handed in Muldersdrift allegedly trying to fill tankers of water to drive down to the Western Cape on Wednesday night, the Mogale City Local Municipality said…..
…The bust was all down to the amateur detecting skills of local ANC ward councillor Molefi Sedibo who told News24 that he just knew “something was not right” when he spotted the double tanker as he drove past the water point in the Muldersdrift CBD.
He said that having been a councillor for 10 years, he was familiar with the timetable followed by the trucks that usually fill their tanks at the water point and knew which service providers delivered the water.
“It was around 17:00 and normally those trucks have already finished work,” he explained.
He had noted in the past that the drivers usually take the tankers back to the depot empty at the end of the day to save on diesel.
“Water is very heavy, so it is very expensive to drive the water to the depot, so they go back empty,” he said.
His suspicions aroused, he also noticed that the tanker did not have the usual logo.
He then blocked the tanker with his car, and got out to ask questions.
Two of the four people working near the tanker bolted when they saw him.
He noticed that they had even brought the specialised equipment needed to connect to the system to get the water into the tanker.
“They got a fright when I started asking: ‘Who gave you permission? Who are you?'” Sedibo recounted.
“I said: ‘The truck will not move until you verify this’.”
…In the meantime, Lipudi wants the police to take swift action because he has since heard from witnesses that it was the third time the truck had taken water without permission.
“Therefore, we want the authorities to get to the bottom of this as a matter of urgency so that we should know who runs a parallel government and doles out free water that belongs to the people of the city so boldly to anyone they feel like.””

“…Crossroad COO Hennie van Wyk explained what happened: “As a commercial business using water in Cape Town, we felt we needed to do something positive toward helping in this time of crisis.”
“We decided to have our commercial cleaning supplier commercially sterilise one of our tankers, fill it with water in Gauteng, and transport it to our facility in Cape Town where we have already initiated other water conserving activities.”
….”Upon arrival at the agreed pickup point for the water, the Crossroads vehicle was rerouted by the bulk water supplier personnel to a different location in Muldersdrift.
“Our people were detained but, upon us producing the legitimate receipt for what we thought was a perfectly legal transaction, authorities were understanding of their roles and nobody has been arrested,” said Van Wyk.
“It’s devastating that criminals will take advantage of us when we are trying to do the right thing.””

/ February 5, 2018Somebody in Britain had a really stupid idea. This is a good article about it (it’s much longer then the quotes below).
A new deep coal mine deep under the sea? Next to Sellafield? Really?
Sam Moisha | 5th February 2018
The first deep coal mine in Britain for thirty years is being proposed at Whitehaven, with the promise of new jobs in an old mining community. But the site is within five miles of Sellafield. Activists are concerned both about the definite contribution to climate change, as well as the potential threat of a nuclear accident. SAM MOISHA sets out their concerns
…
And it gets worse…the undersea mine would be in an area of heavily faulted geology within 5 miles of Sellafield. Sellafield is the most dangerous place in Europe, storing radioactive spent fuel rods in crumbling pools of water.
Friends of the Earth raises some crucial questions in its formal objection to the WCM plan. “We would also query whether or not there has been robust enough analysis of the potential for seismicity (and subsidence) relating to well known nuclear facilities in the wider area, including Sellafield and proposed new facility at Moorside?
“What potential is there for seismicity to effect these and other facilities (including low level waste repository at Drigg) and the possible high level radioactive waste facility which has been proposed in West Cumbria for some time.”
Repeated complaints
The potential for earth tremors and quakes resulting from mining is well known. The potential for man-made tremors at the Sellafield site is too awful to contemplate.
In 2016 The Ecologist reported that: “Especially serious are the ~20 large holding tanks at Sellafield containing thousands of litres of extremely radiotoxic fission products.”
Discussing these tanks, the previous management consortium, Nuclear Management Partners, stated in 2012: “There is a mass of very hazardous [nuclear] waste onsite in storage conditions that are extraordinarily vulnerable, and in facilities that are well past their designated life”
The National Audit Office (NAO) stated these tanks pose “significant risks to people and the environment”. One official review published in The Lancet concluded that, at worst, an explosive release from the tanks could kill two million Britons and require the evacuation of an area reaching from Glasgow to Liverpool.
These dangerous tanks have also been the subject of repeated complaints from Ireland and Norway who fear their countries could be contaminated if explosions or fires were to occur.

With regard to the actual mining there would seem to be several immediate problems, avoid all the pre-1986 mining in the area that went up to 4 miles offshore. They may have plans but they were never that accurate. Water ingress and fire-damp, but the main problem for underground mining is the faulted nature of the area
http://mapapps.bgs.ac.uk/geologyofbritain/home.html?location=whitehaven&gobBtn=go
Hope the link works to the map on the British Geological Survey and click the bedrock only button.
Obviously the company thinks it can overcome this.
Once out of the ground it has to get to market either UK steel works or German ones. Germany used 17.6Mtce of hard coal in its steel industry in 2015, so a market is there if it can displace imports from Russia or S. America. There maybe a political dimension here if the Germans want to reduce reliance on Russia.
For the company to go ahead the price of coal must be the major factor and transportation costs form a large part of the delivered price of coal. Can transporting coal by rail to Redcar, Yorkshire then loading and transporting by ship to N. Europe be competitive?
Current pricing must suggest that they believe they can be competitive as prices in Germany are holding up, but historically the price varies and long term, well who knows
https://www.destatis.de/DE/Publikationen/Thematisch/Preise/Energiepreise/EnergyPriceTrendsPDF_5619002.pdf?__blob=publicationFile
The BGS map shows how heavily faulted the area is, although in the Solway Firth/Irish Sea basin it may reduce as you move away from the mountains (personally I doubt this). But if the company plans to use longwall mining with no backfill, just letting the roof collapse, then reactivation of faults is a real probability. Note in 1786, pre large scale mining, there was an earthquake in Whitehaven, Cumbria estimated at Mag 5:0 and in 1976 Longtown, Cumbria (just north of Carlisle) a Mag 4.7 earthquake.
While I think it is better kept in the ground I think the jobs argument will win out in the local council. I doubt they will even consider the potential for seismic activity.

The US will soon be laggards when it comes to renewable energy sources and environmental protections compared to China, potentially India, and much of the EU. But, it’s clear that the rest of world is moving toward renewable, with or without US participation. In China for example, they have invested heavily in wind turbine manufacturing, solar cell manufacturing, and now battery manufacturing. An example is CATL is racing ahead to match and exceed Tesla’s Gigafactory and has already inked deals with major auto manufacturers in China including VW and BMW.

Permafrost Stores a Globally Significant Amount of Mercury
First published: 5 February 2018Full publication history DOI: 10.1002/2017GL075571
Abstract
Changing climate in northern regions is causing permafrost to thaw with major implications for the global mercury (Hg) cycle. We estimated Hg in permafrost regions based on in situ measurements of sediment total mercury (STHg), soil organic carbon (SOC), and the Hg to carbon ratio (RHgC) combined with maps of soil carbon. We measured a median STHg of 43 ± 30 ng Hg g soil−1 and a median RHgC of 1.6 ± 0.9 μg Hg g C−1, consistent with published results of STHg for tundra soils and 11,000 measurements from 4,926 temperate, nonpermafrost sites in North America and Eurasia. We estimate that the Northern Hemisphere permafrost regions contain 1,656 ± 962 Gg Hg, of which 793 ± 461 Gg Hg is frozen in permafrost. Permafrost soils store nearly twice as much Hg as all other soils, the ocean, and the atmosphere combined, and this Hg is vulnerable to release as permafrost thaws over the next century. Existing estimates greatly underestimate Hg in permafrost soils, indicating a need to reevaluate the role of the Arctic regions in the global Hg cycle.

Dr Sam Dean, speaking this morning to TVNZ 1’s Breakfast programme, said it is undeniable that greenhouse gas emissions have raised Earth’s average temperature over the past 100 years.
High sea surface temperatures in the Tasman Sea have contributed to the power of the storms, he said.
“This is just so unusual … we’re really just in uncharted territory here – this is something we haven’t seen,” Dr Dean said.
January was the hottest month ever seen since records began, Dr Dean said – more than 100 years – and the chances of storms like last month’s occurring naturally are very low.
Dr Dean said natural variation in the seasons was common, with spikes and dips in extreme temperatures, but the data clearly supports the fact that higher temperatures are affecting the weather.
“It’s not really a question of belief, it simply is a question of fact, and that’s how it is,” he said.

Exxon Mobil bets efforts to limit climate change will fail
If climate change curbs live up to their promise, oil demand may fall 20 per cent by 2040, Exxon Mobil says in one forward-looking report. But a more likely scenario is it will grow by 20 per cent, the company says in separate outlook.
The reports were both released Friday. Which one to believe?
The first comes in response to a shareholder vote last year that demanded Exxon publish the risks it faces if the world hits its carbon-emissions goal to limit global warming to 2 degrees Celsius above pre-industrial levels. The second is what the Irving, Texas-based explorer uses “to help guide multibillion-dollar investment decisions,” according to its preamble.
In both instances, the study authors say the world will still need trillions of dollars of investment in fossil fuels to meet its energy needs over the next two decades.
The business outlook, as might be expected, is more hawkish. Its findings show oil and natural gas still supplying about 55 per cent of the world’s energy needs by 2040, with oil the biggest contributor. Coal is expected to fall to less than 30 per cent in 2040 from approximately 40 per cent in 2016.
“Exxon Mobil’s own analysis assumes the world will continue to burn through oil and gas to drive their profits and keep us on a path toward global temperatures well above the 2 degree Celsius target,” said Kathy Mulvey, a campaign manager at the Union of Concerned Scientists, in an email.
“Nowhere do they foresee carbon emissions bending rapidly toward zero – as they must well before 2040,” she wrote.

It is quite astonishing to realize that this is actually working, right now. Keller Rinaudo, CEO and co-founder of Zipline, puts it this way: “They’re not trying to catch up to US infrastructure. They’re just leapfrogging roads and trucks and motorcycles and going to a new type of infrastructure.”

“Melting Permafrost in the Arctic is unlocking diseases and warping the landscape”
https://www.vox.com/2017/9/6/16062174/permafrost-melting
Our world’s northern polar region is warming twice as fast as the global average. And the consequences are easy to spot. On average, Arctic sea ice extent is shrinking every summer. The Greenland ice sheet is becoming unstable.
But perhaps most disturbing are the changes occurring underground in the permafrost. Permafrost is a layer of frozen soil that covers 25 percent of the Northern Hemisphere. It acts like a giant freezer, keeping microbes, carbon, poisonous mercury, and soil locked in place.
When it thaws, a Pandora’s box is unleashed. To better understand the strange changes in the permafrost, I spoke with Robert Max Holmes, an earth systems scientist with the Woods Hole Research Center. When I reached him by phone, he was in Bethel, Alaska, a small outpost town 400 miles west of Anchorage, and had just come back from an eight-day research and teaching expedition in the wilderness.
A week earlier, Holmes and his students had set up temperature sensors in the soil near their encampment. Their first reading was 0.3°C. “It’s barely frozen. And we just sort of sat there stunned. You don’t know whether to cry or what. Because you’re just like: My God, this whole thing is just going to change in a big way.”

======================================================
According to a new study published Feb. 5 in the journal Geophysical Research Letters, theremay be more than 15 million gallons (58 million liters) of mercury buried in the permafrost of the Northern Hemisphere — roughly twice as much mercury as can be found in the rest of Earth’s soils, ocean and atmosphere combined.

Incidentally, somewhere above I saw that coal was blamed for much of the mercury in the world’s oceans. That’s largely – but not totally correct. What’s caused “artisanal gold mining” is believed to be slightly larger cause. It’s where small gold miners use mercury to collect and concentrate gold, then burn off the mercury.

That thinning in turn changes the temperature structure of the stratosphere, which then changes the dynamics of the lower atmosphere, especially wind and weather patterns. The cooling is not uniform. While areas of Europe chilled during the Maunder Minimum, other areas such as Alaska and southern Greenland warmed correspondingly.
