Climate Change Induced Drought and Fire at Critical Stage in Chile — Construction of 12 Desalination Plants Underway

In the National Forests of Chile, it’s been burning since February.

An intense upshot of the stifling of water supplies through month after month of heat and lack of rainfall. A kind of intense onset, persistent drought that has become all too common in a world in which atmosphere, ice and ocean temperatures keep rocketing on to new record highs.

Starting February 17th, massive fires erupted, spreading swiftly through Chile’s forested mountainsides and valleys, threatening protected woods and endangered species. The fires have continued off and on now for more than a month — fueled by hot winds and a record drought that has forced the nation to build 12 desalination plants in a desperate effort to restore the country’s ebbing water supply.

Reports from BBC indicated that today’s fires are burning in three protected national parks: China Muerta National Reserve, Nalca Lolco National Reserve and Conguillio National Park. The fires threaten ancient growth forest that is the abode of the majestic Araucaria araucana trees. A kind of pine that can live up to a thousand years. Over 4,500 hectares are now burning and the smoke is plainly visible in the NASA satellite shot (right frame in the image sequence above). Fully fifteen fire brigades are involved in what is currently a massive firefighting effort.

Overall, the fires that have been raging for more than a month throughout Chile have consumed an exceptional 91,000 hectares — nearly double the 59,000 hectare per year average over the last five years. Years that themselves experienced increased heat, drought, and burning.

This extreme burning comes as Chile faces a ramping, multi-decadal water shortage set off by human warming. Climate scientists there have indicated a high risk of drastically increased drying throughout Chile over the next 35 years through to 2050 due to climate change related impacts.

According to President Michele Bachelet the country’s current drought situation is already at critical stages. Bachelet recently announced millions of dollars in funds to drill for underground water and to construct desalination plants to provide drinking water to fight ramping drought conditions with the ugly prospect of more to come.

In a report today from BBC, Bachelet noted that the situation was now endemic and expected to worsen:

“Faced with this critical situation, there is no choice but to assume that the lack of water resources is a reality that is here to stay and that puts at risk the development of important regions of our country.”

Though climate change is expected to continue to ratchet down on drought impacts to Chile — increasing heat, melting critical glacial ice, and drying out forestlands — this year, at least, there appears to be some hope for an end to the stifling heat and the ongoing fires. Hints of the first rains of autumn have now begun to show up in Central and Northern Chile.

But by 2050 with the world expected to be between 1.5 and 2.5 degrees Celsius hotter than 1880s averages, the autumn rains will have been brutally beaten back — retreating further and further into fall. In that time, the heat and dryness of spring and summer will come early and the great glaciers upon which Chile depends so much for its water will be but wan shadows of former grandeur. If they exist at all.
