Reverend Jesse Jackson called on each of us to be heralds of change, to be messengers of hope; to step forward and say β€œSend me” wherever we have a chance to make an impact.

How fortunate we were that Jesse Jackson answered that call. What a great debt we owe to him.

My ICQ UIN is 7231680. That number is burned into my consciousness. I inadvertently learned that you could see private conversations in public chat rooms when using Telnet instead of a browser on GeoCities. I can tell you the difference in audible dial-up handshakes between 1200, 2400, 14.4 kbps modems. I needed a edu email address to join Facebook after my university was admitted. We were here at the beginning. We made social media. You wouldn't be in my Top 8. I have usernames older than you.

1/ Remember when Ted Cruz went to CancΓΊn as the Texas power grid failed? It wasn't just the people of TX left behind, it was also the wildlife. Out now @natecoevo.nature.com, our paper led by @mstager.bsky.social & @treeswallows.bsky.social documents how bad the storms were for birds.

WATCH: Trump, EPA's Zeldin announce end of scientific basis for U.S. action on climate change The Trump administration on Thursday revoked a scientific finding that long has been the central basis for U.S. action to regulate greenhouse gas emissions and fight climate change, the most aggressiv...

Today, the Trump administration repealed the endangerment finding: the ruling that served as the basis for limits on tailpipe emissions and power plant rules. Without it, we’ll be less safe, less healthy and less able to fight climate changeβ€”all so the fossil fuel industry can make even more money.
