Hi folks,

I hope you've seen the plug to sign onto the letter that's generated a flurry of messages on Green Gurus--I also emailed it out directly to everyone. We've got lots of architects on board, and a handful of engineers, but I think we just have one contractor so far (Thanks Theresa!)--it would be really awesome to have more.

I'm still basking in the glow of yet another great Summit. I hope others who were there are feeling the same.

Here are the flip-chart pages from the many round-table conversations. Five-minute presentations to come shortly, followed by the Summit Report.

Feel free to use this thread to share other resources and thoughts.

This just in from Berkeley Earth. The definitive report on 2023 global temperatures. Lots of incredible graphs to peruse but the news is pretty incredible. Actual temperatures far surpassed predictions. "At the start of 2023, we foresaw only a 14% chance that 2023 would become a record warm year, and only a ~1% chance that 2023 would reach 1.5...
