'Delay means death': We're running out of ways to adapt to the climate crisis, new report shows. Here are the key takeaways

Climate change is on course to transform life on Earth as we know it, and unless global warming is dramatically slowed, billions of people and other species will reach points where they can no longer adapt to the new normal, according to a major report published Monday.

The UN-backed report, based on years of research from hundreds of scientists, found that the impacts from human-caused climate change were larger than previously thought. The report's authors say these impacts are happening much faster and are more disruptive and widespread than scientists expected 20 years ago.

The authors point to enormous inequities in the climate crisis, finding that those who contribute the least to the problem are the worst affected, and warn of irreversible impacts if the world exceeds 1.5 degrees Celsius of global warming.
