Given publication of another study showing that conventional forestry is a major contributor to the 'wildfire crisis' in the West, here's a thread that breaks down this issue & explains why changing forestry practices is so central to addressing our current dilemma.🧵🌏 www.latimes.com/environment/...

New research explains why forests planted for logging purposes fuel devastating wildfires more often than untouched land.

Yet again, actual data show wind and solar are the least expensive power on the grid (and getting cheaper by the day). So the Trump administration is just lying about that.

If someone tells you the CO2 is coming out of the sea, they try to fool you. We know exactly where it comes from and where it goes. We emit CO2, about half of that stays in the atmosphere, and a quarter each is taken up by oceans and forests.
Measured facts!

We have reached 1.4 degrees celsius #globalheating according to NASA data (smooth black trend line). Breaching 1.5 is now inevitable. From now on the fight is to keep overshoot as small and short as possible.

Never forget: At breakneck speed we are leaving the stable Holocene climate in which human society developed and thrived. Weather extremes are outside historical experience. Sea-level rise is accelerating. Dangerous tipping points are ahead.

What Gates is putting forward aren’t legitimate arguments that can be made in good faith. They are shopworn fossil fuel industry talking points.

Here are my three truths about climate:
1. We fail if we don’t end free-to-pollute fossil fuel model. Period. Game over.
2. A crash looms, prefigured by collapse in home insurance/mortgage markets.
3. There are true villains in the story, and we have to tell it that way.
