Will, as you have written, the science is clear: we are heading for catastrophic tipping points.
But, despair that leads to inaction will make it worse. We can slow the trajectory of climate change, and that will give living systems more time to adapt and survive. There is one very important way to do so, which I hope you will investigate: reducing our emissions of a small class of Climate Super-Pollutants that have a powerful warming effect, but are short lived: methane, HFCs (refrigerants) and black carbon (soot). Here is the best book on that: Cut Super Climate Pollutants Now! by three experts. Much progress has been made on global agreements to limit methane emissions. This will buy us some time.
Getting off natural gas is important, and if we are lucky, Europe will shift from Russian Gas to renewables on an accelerated timeline. Not happening yet! This is one place we can all push--because nat gas prices are now intolerably high across Europe.
