Climate change caused the demise of Central Asia's river civilizations, not Genghis Khan

A new study published in Proceedings of the National Academy of Sciences suggests that climate change, not Genghis Khan, led to the decline of Central Asia's medieval river civilizations. The research found that decreasing river flow due to drought was equally important for the abandonment of these city-states as the Mongol invasion.

Error correction means California's future wetter winters may never come

Researchers found that California's winter precipitation projections are likely to be drier than expected due to a persistent error in climate models known as the double-ITCZ bias. This bias can lead to reduced winter precipitation, less spring runoff, and increased wildfire risk in the state.

Oceanographers have an explanation for the Arctic's puzzling ocean turbulence

A new study by MIT researchers reveals that Arctic eddies are driven by ice friction and ocean stratification, leading to a seasonal shift in their activity. The findings suggest that as the Arctic loses summertime ice, waters will become more turbulent, with implications for climate change predictions.
