Climate - truthful information about climate, related activism and politics.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

As fires rage through southern California, the costs of extreme weather events linked to climate change are forecast to keep climbing – adding fuel to growing efforts by some US states to make the oil and gas industry liable for helping foot the bill despite looming legal challenges.

On a level of discussion between “the earth is flat” to “you can pollute as long as you pay for it”, we’re still very far from stopping the madness.

Putting out every little forest fire in an eco system where natural fires were commonplace is the cause of these humongous fires we can't put out.

Climate change isn't the main culprit here.

"[...] attempting to suppress all wildfires necessarily means that fires will burn with more severe and less diverse ecological impacts, with burned area increasing at faster rates than expected from fuel accumulation or climate change. Over a human lifespan, the modeled impacts of the suppression bias exceed those from fuel accumulation or climate change alone, suggesting that suppression may exert a significant and underappreciated influence on patterns of fire globally"

We figured this out from the Yellowstone National Park fires of '88.

I was in forestry class a couple of years later and the professor lectured on it. He had been there, seen the dead wood stacked 10'-15' high. Can you fucking imagine?!

We spent decades and decades putting out every little fire and went surprised Pikachu when 800,000 acres exploded in a firestorm of biblical proportion. Have we learned nothing in 40-years?!

Given the Santa Anna winds funneling fire down the LA valleys and Hurricane Helene funneling the rain down the mountains to flood North Carolina, I'll stand pat, just a bit upland in Florida.
