Heatwave Mass Casualties Strike India in April Amidst Severe Drought, Water Shortages

Loss of water from snow melt in the Himalayas, increasing temperatures and instances of drought over the food-producing plains, and a potential endemic weakening of the annual monsoonal rains. These are all climate change related impacts that appear to be settling in over India as global temperatures consistently begin to hit levels higher than 1 C above 1880s values. Impacts that are setting up conditions for sustained and increasingly severe droughts and heatwaves.

Yesterday, temperatures rocketed to 114.44 degrees Fahrenheit (or 45.8 degrees Celsius) in Bhubaneshwar, the capital of Odisha, on the Indian east coast. It was the hottest April reading ever recorded for a region that typically sees daily highs in the upper 90s this time of year. A level of heat that’s excessive even for this typically warm region.

Bhubaneshwar, however, was just one of many locations experiencing temperatures above 110 Degrees (F) yesterday. For a broad heatwave and a related severe drought has sprawled over much of India throughout early April — hitting a peak intensity for many locations this week. Heat so intense that it had already resulted in the tragic loss of more than 110 lives due to heat stroke by April 9th.

India’s Two Year Drought

The drought itself is an ongoing feature — one that has lasted now for two years in many provinces as abnormally high temperatures and reduced monsoonal rains have produced severe and widespread impacts. In total, 10 of India’s 29 states are now suffering under drought conditions. Some locations, like the Maharashtra town of Latur, east of  Mumbai, are experiencing water shortages so severe that Indian officials have dispatched a drought relief train — containing a half a million liters of water — to provide aid. For hardest hit areas, the situation is so dire that riots are now a risk — prompting authorities to outlaw gatherings of more than 5 people near some water distribution sites. Maharashtra itself is experiencing some of the most severe losses with reports indicating that reservoirs there are at less than 5 percent capacity. Average capacity for all reservoirs throughout India amounted to just 29 percent by the end of March — and the annual monsoonal rains are still at least two months away.

Overall impacts are quite widespread. Ranchi, the capital of Jharkhand has declared a water emergency. And the Ganges River is now so low that it is unable to provide water to cool one of the largest coal-fired electrical power stations in West Bengal — forcing it to suspend operations.The great river is dramatically shrunken — causing islands of mud to emerge even as pollutants concentrate in its thinning thread. A diminishing flow that India’s 1.3 billion people rely on for much of their water. It’s a greater crisis so extreme that late last month one of BBC’s India correspondents asked — is this the worst water crisis India has ever faced?

Such broad-ranging and long-lasting drought has hit India’s farmers hard. Last year, more than 3,500 farmers committed suicide after facing some of the worst conditions ever to strike India. This year, the situation is arguably even worse — forcing some desperate regions to consider cloud seeding as a means of possible drought alleviation.

Stronger Monsoon for 2016? Or Will A Warming Globe Dim India’s Hopes For Rain?

Reports from India’s Meteorological Division have called for a normal to above normal monsoon to provide replenishing rains this year. However, monsoonal predictions over the past two years were overly optimistic, which is cause for caution over last week’s forecast.

Overall, the early extreme record heat and drought over India provides a barrier to any influx of monsoonal moisture. In addition, El Nino conditions — possibly hanging on in the Central Pacific through June — may help to dull or delay monsoonal development even as a predicted progression to La Nina later in the year provides some hope for additional moisture during late Summer and Fall. A switch to rains that may well be quite intense for some regions given the unprecedented atmospheric moisture content as a result of record high global temperatures.

Longer-term, there are growing indications that climate change is starting to impact India’s breadbasket. Record high temperatures over the Gangetic Plain — India’s productive farming region south of the Himalayas — are starting to take hold as a result of a human-forced warming of the globe. A condition that IPCC reports indicate could decimate (reduce by ten percent) wheat, corn, soy and sorghum yields over the coming years. So even as a shift to La Nina provides some hope for an alleviation of India’s current drought woes later in 2016, the larger trend is for an increasing prevalence of drought and extreme heat as a reckless fossil fuel emission continues to force the globe to warm.
