Climate change is causing mountain snow to melt more rapidly and glaciers to shrink, but this is making a widely varied impact on water supplies in Asia, a new paper by PSI Senior Scientist Jeffrey Kargel says.

New research led by the University of Cambridge has found rare evidence - preserved in the chemistry of ancient rocks from Greenland - which tells of a time when Earth was almost entirely molten.

If the world is to maintain a sustainable economy and fend off the worst effects of climate change, at least one industry will soon have to ramp up dramatically: the mining of metals needed to create a vast infrastructure for renewable power generation, storage, transmission and usage.
