Howling winds take sea salt from the Southern Ocean and lay it down in Antarctica as snow, then ice. Hidden in these ice cores is a warning about Australian fire seasons.
Did the enormous West Antarctic Ice Sheet collapse the last time global temperatures were 1.5°C above preindustrial levels? The answer lay in the DNA of an octopus.
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?
Long before thermometers, nature left its own temperature records. A climate scientist explains how ongoing global warming compares with ancient temperatures.
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.
Australia’s alpine region warmed for about 600 years. What makes this climate change particularly interesting is that it bears striking similarity to today.
Scientists studied charcoal layers in the sediment of lake beds across the Rockies to track fires over time. They found increasing fire activity as the climate warmed.
These findings are in stark contrast with the original worldview that suggested the entire globe was at a maximum glaciated state around 20 000 years ago.
What caused the rise and then collapse 2,600 years ago of this vast empire centered on Mesopotamia? Clues from a cave in northern Iraq point to abrupt climate change.
