Glaciers across High Mountain Asia are losing more than 22 gigatons of ice per year. The impact of a warming climate on glacial loss is undisputed—this new study provides the first evidence that seasonal shifts in rainfall and snowfall patterns, particularly of the South Asian monsoons, are also exacerbating glacier melting across the region.

Carbon dioxide levels in the atmosphere vary naturally between ice ages and interglacial periods. A new study by researchers at the University of Gothenburg shows that an unexpectedly large proportion of carbon dioxide emissions after the ice age may have come from thawing permafrost.

The Philippines, like other tropical countries, is known more for its balmy climate than for hailstorms. But a new Philippine study—the first of its kind—has found that the country’s hottest days are, in fact, more likely to produce hail.

Some Fourteen thousand years ago, algal blooms in the Southern Ocean helped to massively reduce the global carbon dioxide content of the atmosphere – as has now been revealed by new analyses of ancient DNA published by a team from the Alfred Wegener Institute in the journal Nature Geoscience. In the ocean around the Antarctic continent, these algal blooms had a significant impact on global carbon dynamics. The current and expected future decline in sea ice in this region now poses a serious threat to these algae, which could incur global consequences.

A new paper on the science-policy interface by climate experts Svante Bodin and Örjan Gustafsson at the Bolin Centre for Climate Research, Stockholm University, calls for urgent reform to the relationship between the Intergovernmental Panel on Climate Change (IPCC) and the United Nations Framework Convention on Climate Change (UNFCCC).
