It is becoming increasingly irresponsible to focus solely on the physical modeling elements of overshooting [2.7°F/1.5 °C of warming]. We need to start thinking about what the [human] scenarios look like for a post-1.5 °C world. @wxpizza.bsky.social. ow.ly/I3G850XNaTY @climate.columbia.edu @vox.com
We’re passing a dangerous global warming threshold — but we’re not doomed
This major climate target has been dead for years. Now, people are finally acknowledging it.
