Cover of IPCC's special report on 1.5°C warming

Some Things You May Have Missed This Week

The Administration didn’t take the week off from undermining efforts to protect the environment.

As many of us were, I was riveted for much of the past several days by the news and hearings regarding Judge Kavanaugh’s potential appointment to the United States Supreme Court.  It’s easy to feel these days as though any one aspect of what’s happening politically at any given moment could occupy all of our …
