Council on Foreign Relations

The COP27 climate conference in Sharm el-Sheikh, Egypt, closes out another year of disasters: record-breaking floods, deadly heat waves, and devastating droughts. The urgency for the world’s leaders to make progress at this conference has never been higher, but many obstacles remain. The Council on Foreign Relations explains the issues and lays out what’s at stake in the world’s fight against climate change.

CNN — Four years ago, Morris J. Alexie had to move out of the house his father built in Alaska in 1969 because it was sinking into the ground and water was beginning to seep into his home.

“The bogs are showing up in between houses, all over our community. There are currently seven houses that are occupied but very slanted and sinking into the ground as we speak,” Alexie said by phone from Nunapitchuk, a village of around 600 people. “Everywhere is bogging up.”

What was once grassy tundra is now riddled with water, he said. Their land is crisscrossed by 8-foot-wide boardwalks the community uses to get from place to place. And even some of the boardwalks have begun to sink.

“It’s like little polka dots of tundra land. We used to have regular grass all over our community. Now it’s changed into constant water marsh.”

As world leaders assemble for the United Nations climate change conference (COP27) in Egypt, it’s hard to be optimistic the talks will generate any radical departure from the inexorable rise in global carbon emissions over the past two centuries.

After all, before last year’s Glasgow talks, experts warned the summit was the world’s last chance to limit global warming to 1.5℃ this century. And yet, a UN report last week found even if all nations meet their climate goals this decade, the planet would still heat by a catastrophic 2.5℃.

You may be hearing the phrase “loss and damage” in the coming weeks as government leaders meet in Egypt for the 2022 U.N. Climate Change Conference.

It refers to the costs, both economic and physical, that developing countries are facing from climate change impacts. Many of the world’s most climate-vulnerable countries have done little to cause climate change, yet they are experiencing extreme heat waves, floods and other climate-related disasters. They want wealthier nations – historically the biggest sources of greenhouse gas emissions – to pay for the harm.
