Right, okay, so, Springsteen and Morello playing Ghost of Tom Joad at First Avenue in Minneapolis at a concert for the resistance. Just saying. You got time for this right?

Someone needed to write this…Powerful, angry and moving words from Springsteen.
I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

River need greater protection, but to date our methods for tracking protection status have been limited. In this post I describe a new method from @oldenfish.bsky.social @americanrivers.bsky.social and Conservation Science Partners - the Protected River Index

Record heat is the new normal, says WWF's @stephanieroe.bsky.social, as 2025 ranks among the three hottest years ever. The good news? Climate solutions are breaking records too. Rapid emissions cuts are possible. More here: t.co/Ph4h3mU6i8

I love the boardwalk at @audubon.org Corkscrew Swamp Sanctuary in SW Florida. Such a great way to experience a range of wetland habitats and to see wildlife close up
