Scientists say the world needs to think about a worst-case "climate endgame"

A team of international scientists says the world needs to start preparing for the possibility of a "climate endgame" as extreme weather events keep ravaging the planet.

From raging wildfires to catastrophic flooding, the effects of climate change can be seen all around. So far, the conversation has been primarily about how to prevent it from getting worse. United Nations Secretary-General Antonio Guterres issued a dire warning at last month's Petersberg Climate Dialogue conference in Berlin, Germany: "Half of humanity is in the danger zone from floods, droughts, extreme storms and wildfires. No nation is immune," he said.

Now a team of international experts led by Cambridge University in England says that even as nations set goals to reduce emissions, we should be prepared for failure.
