A quick review of the DOE's new 'critical review' of climate science. Whether it's worth a formal community response - I'm still not sure, but here's my first thoughts

Lots of adaptation $$ will be needed soon, and there won’t be enough for everything: “the cost of maintaining roads in just the US will increase by $100 billion a year by 2050 (in 2018 dollars), or roughly half of what state and local governments spent on roads in 2021.”
Around 10 years ago I almost died because a road not built with climate change in mind was so wrecked it damaged the bus I was on. I knew that I would eventually write a story about how climate change is wrecking roads, and endangering lives. This is me trying to explain that. Gift lift.
These Roads Aren’t Built for Wilder Weather Driven by Climate Change
Important motorways across the world weren’t designed to withstand more extreme temperatures and rainfall.
