Earth’s greatest mass extinction 250 million years ago shows what happens when El Niño gets out of control – new study

We modelled the climate during this period and discovered episodes of intense ocean heating.

What 2,500 years of wildfire evidence and the extreme fire seasons of 1910 and 2020 tell us about the future of fire in the West

As the climate warms, devastating fires are increasingly likely. The 2020 fires pushed the Southern Rockies beyond the historical average. Is there hope for the Northern Rockies?

Is it really hotter now than any time in 100,000 years?

Long before thermometers, nature left its own temperature records. A climate scientist explains how ongoing global warming compares with ancient temperatures.

Was Earth already heating up, or did global warming reverse a long-term cooling trend?

Evidence in Earth’s natural archives, from tree rings to seafloor sediments, points to one trend. Some climate models suggest another. Here’s why are important.

Glaciers have existed on Earth for at least 60 million years – far longer than previously thought

Scientists used satellites to map tens of thousands of glacial landforms in Antarctica’s highest mountains.

1,000-year-old stalagmites from a cave in India show the monsoon isn’t so reliable – their rings reveal a history of long, deadly droughts

As water dripped in a remote cave, it left behind evidence of every monsoon season for a millennium. Scientists say it holds a warning for a country about to become the most populous on Earth.
