Listening to @volts.wtf recent panel/podcast with @mliebreich.bsky.social , discussing his "Pragmatic Climate Reset", published in two parts at BNEF last September.
Michael mentioned his "simplest energy model ever" - just 4 parameters - and I decided to sketch up and add emissions and temps.

One important finding for me was the overwhelming negative imagery that people have about climate change, when we asked an open-ended question about the first image that came to mind. We're missing positive imagery and narratives about the transition and climate action.

Economic models often predict less dramatic changes than you would infer from popular discussions & even from financial markets.
They're predicting 0.75-1.5pp less growth this year as a result of the biggest tariff increase in U.S. history. Large but not historically memorable.
