New research links the amount of carbon dioxide taken in by land ecosystems, such as forests, to the availability of water, which is in short supply during droughts.
The health impact of air pollution from ammonia and nitrogen oxides, which react to form particulate matter and ozone, substantially outweighed climate impact from nitrous oxide in all regions and years.
In coming decades, many regions of the world will enter permanent dry or wet conditions under modern definitions of drought, according to new research. The findings reveal the importance of rethinking how we classify these events as well as how we respond to them.
A new effort to reconstruct Earth's temperature and climate since the last ice age, about 24,000 years ago, highlights the main drivers of climate change and how far out of bounds human activity has pushed the climate system.
Unless CO2 emissions drop significantly, global warming will make the Amazon barren, the American Midwest tropical, and India too hot to live in by 2500, according to a team of scientists.
A little more sexy time for symbionts could help coral reefs survive the trials of climate change, researchers report. And that, in turn, could help us all.
