Greenhouse gas emissions could reduce drag in the upper atmosphere, leaving more space debris in orbit and making satellites more vulnerable to damage, according to new research

Climate change isn’t just affecting Earth, it’s reshaping space as well. A new MIT study reveals that rising greenhouse gas emissions are shrinking the thermosphere, reducing atmospheric drag and allowing space debris to linger longer,

Douglas McIntyre, Editor-in-Chief at Climate Crisis 24/7, reports that climate change is weakening Earth’s atmospheric friction, increasing the risk that falling satellites won’t burn up completely before reaching the surface.

The signatories to an open letter calling for IOC action on climate change range from Australia's most decorated Olympian, swimmer Emma McKeon, to Cyrille Tchatchet II, a weightlifter who represented the refugee team at the Tokyo Olympics in 2021.

More than 400 athletes, including more than 20 Canadians, speak up about threat of climate change to both the Winter and Summer Olympic Games.
