Climate Science Is Catching Up to Climate Change With Predictions That Could Improve Proactive Response

In Africa, climate change impacts are experienced as extreme events like drought and floods. It has now been possible to predict and monitor these climatic events, providing early warning of their impacts on agriculture to support humanitarian and ...

What Causes Mudslides and Floods After Wildfires? Hint: It's Not What Scientists Thought

Scientists once assumed that flooding and mudslides after wildfires were linked to the waxy coating that builds up on charred soil, preventing water absorption. Researchers found that water flow came from absorbed water in both burnt and unburnt ...

Our Favorite Vintages and Their Precarious Mountainside Homes Are at Risk Due to Climate Change, Environmental Scientists Warn

Tucked into the hillsides of Italy, Portugal, and Spain, some of the world's most famous -- and most difficult to maintain -- vineyards are heralded for their unique flavor profiles and centuries of tradition. But as extreme weather and changing ...
