Forests across the world are transforming as the Earth heats up and as more frequent and severe droughts, wildfires and disease outbreaks destroy trees.

In a new report published in Science magazine, researchers warn that climate change is accelerating the death of trees, stunting their growth and making forests across the world younger and shorter.

More dams will collapse as aging infrastructure can’t keep up with climate change

spike

The collapse of two Michigan dams on Tuesday following heavy rainfall has triggered concerns over how precarious dam infrastructure in the U.S. is inadequate to handle severe weather.  

Aging dams will increasingly fail as climate change makes extreme precipitation and storms more frequent and intense, scientists warn.

“A lot of the country’s infrastructure systems were built during a time when these kind of weather events were considered rare and didn’t present a significant threat,” said Hiba Baroud, a professor of civil and environmental engineering at Vanderbilt University.

“But things have changed. The climate has changed. These dams are aging

Climate change is hindering progress on cancer prevention and increasing people’s exposure to deadly carcinogens, according to a new report from scientists at the American Cancer Society and Harvard University. 

Hotter temperatures worldwide have fueled more frequent weather disasters like hurricanes and wildfires that release vast amounts of carcinogens into communities and delay access to cancer treatment. 

“The prospects for further progress in cancer prevention
