Heat waves, droughts, floods, wildfires, disease outbreaks and other dire effects of climate change are accelerating more rapidly than scientists expected in many parts of the world, including in North America.
Volunteer firefighters rest west of Yakutsk, Russia, in August 2021. Wildfires are getting more common in Siberia, undercutting the ability of the region's vast forests to absorb carbon dioxide from the atmosphere. Billions of people on every continent are suffering because of climate change, accordingreleased on Monday. And governments must do a better job of protecting the most vulnerable communities while also rapidly reducing greenhouse gas emissions.
Still, the authors of the report make clear, humans are not powerless. Repairing damaged ecosystems and reducing greenhouse gas emissions dramatically and immediately would spare billions of people from illness, poverty, displacement and death.Some of the most delicate ecosystems have already been irreversibly altered by climate change with serious implications for global warming later this century.
For that reason, protecting natural landscapes far from human settlements is an important way to protect human life and health, too, the report notes. The authors return again and again to the deadly effects of heat waves. Around the world, high temperatures are killing people and making them sick.
