Many glaciers seem to have already reached a tipping point, after which freshwater runoff will begin to decline

New research is helping quantify just how big that effect might be

Scientists believe they can better pinpoint how much future warming the world can expect

Storms and heavy rainfall events that cause flooding are expected to become more severe

Scientists have discovered an unexpected consequence of the shifting polar landscape

Extreme event attribution is one of the most rapidly expanding areas of climate science

Research breakthroughs astound scientists

One reason is that warmer air can hold more moisture, which leads to greater amounts of precipitation, including snow

Changes in global temperatures could affect air flow around the planet

It is still unclear how changes in migration timing might affect whole populations or species

Scientists increasingly agree that the world may need negative emissions to prevent catastrophic warming

Thawing glaciers may speed up acidification of ocean water

Scientists say that even under the Obama administration, the number may have been set too low

Soil management offers huge potential for keeping carbon emissions in the ground

New research predicts how coastlines around the world will be affected by ice melt in different places

It is unclear whether the renewed uptick in emissions will become a trend

A new study suggests that long periods of cold, dry weather helped drive epidemics in ancient and pre-modern China

The mapping project will help scientists understand how much of the Greenland Ice Sheet is threatened

Scientists are increasingly worried about the Totten Ice Shelf's vulnerability to warm ocean water

Carbon-rich peat bogs seem to adapt well to changes in temperature, precipitation and other climate-related factors

Fossilized corals off Texas show that in the past, sea level rose several meters in just decades, probably due to collapsing glaciers

A key argument used to downplay the consequences of climate change is resurfacing

Scientists think that global warming may already be influencing fire seasons
