President Barack Obama shouts out co-host Columbia Climate School for our work advancing this important field of study and action at a student roundtable at #COP26. (As a member of the class of ’83, he jokes he may be biased.) Watch: bit.ly/3mS472S The Obama Foundation

Restricting the U.S. EPA's regulatory power is a step backwards that undoes decades of progress and limits the United States' ability to control its emissions in the future. Those tackling climate today will need to work harder for a just, sustainable world. nytimes.com/live/2022/06/3…
