For decades, it was impossible to say that a specific weather event was caused, or even made worse, by climate change. But advanced research methods are changing that.

Many of this year's deadly extreme weather is linked to climate change and scientists warn they're a sign of what's to come.

The effort, which will begin in 2022, will help the city with its disaster response if a heat wave is ranked as more dangerous. Seville's mayor hopes other cities follow suit.

Heat waves are getting longer and more intense with climate change, which increases the risk of preterm birth. Pregnant women often don't hear about the dangers.

A new study says the current climate crisis is a "severe threat" to the safety of younger generations, who will experience far more extreme climate events such as heat waves, wildfires and floods.

With the global pandemic still in the spotlight, more than 200 leading health journals say climate change is an even more urgent threat.

2020 and 2016 are virtually tied for the hottest year on record. That means more powerful hurricanes, more intense wildfires, less ice and longer heat waves.

Heat waves, air pollution and extreme weather are making people sick and, increasingly, killing people. A key report by global physicians says fossil fuels are to blame.
