During the last Ice Age, massive slabs of ice covered much of North America, but new research now shows that calving icebergs resulted in a huge influx of freshwater that increased the production of the greenhouse gas, methane, in tropical wetlands.
Prehistoric climate changes that took place thousands of years ago are apparently hidden inside Indian cave deposits (not pictured), and may hold clues to better predicting future climate in the region, according to new research.
It seems that extreme weather including torrential rains and blazing heat is becoming the new norm, and now new research indicates that more than half of hot extremes are caused by climate change.
As the global climate continues to change and extreme weather becomes the new norm, annual rainfall is expected to increase in certain parts of the tropics. Now new observations have shown that more big thunderstorms are behind this boost in total tropical rainfall.
Remember that El Niño that experts were predicting? Well, it's finally here, but the NOAA is warning that might not mean more rain for America's thirsty southwest coast, despite traditional weather patterning.
Scientists have re-engineered certain cereal crops so that they can better brace for flooding in world where extreme weather is becoming the new norm.
In the face of climate change, scientists often focus on the harmful effects of greenhouse gas emissions, but new research shows that tropical deforestation triggers global changes that are just as costly as carbon pollution.
A new NASA-funded study has found that a dried out Amazon, which has experienced a decline in rainfall over the last decade, could speed up global climate change due to the subsequent drop in vegetation.
African rainfall may rise with greenhouse gas levels, according to a new study.
A new study has found that pollutant emissions produced by human activity has been causing the world's total annual monsoon rainfall to decline over the past five decades. And while that may be good news for some flood-prone regions, experts do not doubt that it has had a significant adverse impact on delicate ecologies.
