Half a dozen or more tornadoes touched down in the Chicago suburbs Monday, with more severe storms possible in the next few days. Those come as hot and humid conditions have prompted extreme heat warnings — and on the heels of a stark new report on climate change.

What could drier-than-normal weather mean for your garden and the greater climate? A climate change specialist and floral expert weigh in.

After getting walloped by two big snowstorms, the area is now bracing for bitter cold later this week. We asked Argonne National Laboratory climate scientist Scott Collis what to expect, and what’s driving the arctic chill.

Hurricanes, wildfires, a destructive derecho and more: it was a banner year for intense weather events around the world and right here in the Midwest.

It’s estimated that roughly two billion people around the globe are now under some form of stay-at-home order. This significant slowdown in economic activity has also led to an environmental impact, particularly in the air.

Australia’s unprecedented wildfires are supercharged thanks to climate change, the type of trees catching fire and weather, experts say. Here are a few questions and answers about the science behind them.
