Volcanic heat source found beneath Antarctic glacier – an annotated infographic

While analysing Antarctic water samples, scientists have discovered a substantial volcanic heat source beneath Pine Island Glacier. Elevated levels of helium-3 gas detected in the waters around Pine Island glacier indicate volcanic activity beneath the ice sheet – exhibiting as much as 25 times more thermal energy than a dormant volcano. The volcanic heat source is one more factor to account for when modelling the stability of the West Antarctic Ice Shelf. The shelf’s stability has serious implications for the future of sea level rising. Click on the graphic for an expanded view.

India on brink of worst-ever water crisis – an annotated infographic

India is suffering from the worst water crisis in its history, with 600 million people facing acute water shortage, a government think-tank says. The crisis is only going to get worse. By 2030, the country’s water demand is projected to be twice the available supply, implying severe water scarcity for hundreds of millions of people and an eventual 6 per cent loss in the country’s GDP. 21 Indian cities, including New Delhi, Bangalore, Chennai and Hyderabad, are likely to run out of groundwater by 2020. States ranked lowest at managing water – such as Uttar Pradesh, Bihar, Rajasthan and Haryana … Continue reading India on brink of worst-ever water crisis – an annotated infographic
