Climate models and geologic archives are at odds over whether Earth gradually warmed or cooled over the past few thousand years. Researchers tackle this global "temperature conundrum" in a new paper.
Tree-ring, ice core and volcano experts teamed up to identify one of the most climatically impactful volcanic eruptions in 4,000 years – Aniakchak II. In the process, they narrowed down potential dates for the infamous Thera eruption.
UArizona researchers were leaders in a worldwide effort to understand tropical trees and their futures under climate change. They found that heat and drought slow the growth of these trees, which are major carbon dioxide absorbers.
Irina Panyushkina grew up in Siberia, hearing stories of explorers trudging through seas of ice to reach the North Pole. She is now a climate scientist trying to understand how a warming world is transforming the place she called home.
Most scientists researching California's extreme weather have focused their investigations on the last decade. But new UArizona research finds that an increasing trend in extreme weather began half a century ago.
Hurricanes and tropical storms are slowing down and dumping more water in the process. At-risk communities could use new research findings to prepare for future disasters.
The online format promises just as much interaction with authors, just as many engaging children's activities and, of course, plenty of opportunities to get your hands on your next favorite book.
When Iceland's Laki volcano erupted in 1783, its effects rippled around the world. Researchers analyzed tree rings to understand how climate responded in northwestern North America. The work will help fine-tune future climate models.
