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.

This article is frustrating for me. Especially his take on trees. The article states the target goal/amount of trees planted would only reduce carbon 6%. Ok, but, it will reduce temperature. I live in WV near a state forest. It is typically 7°-15° F cooler at my house than in town. Additionally, the sun in the summer doesn't even hit my house until noon-ish, which significantly reduces my air conditioner consumption.

I chose to share this mostly for awareness. I am not especially fond of his perspective.

Trees remove CO2 then die and release it back.

We can't grow back forests like they were at any relevant speed to even 'make a dent' in CO2 emissions.

The only way to stop is to end coal, oil and gas oxidation to CO2. All other things are misdirection, at best.

Exactly. The first thing we need to do is stop extracting extra carbon from the ground.

Then we literally need to start reducing the amount of carbon in the atmosphere, probably by literally growing trees, cutting them down and them straight up burying them deep underground.

There's always a problem with grammar and pronouns. I am not, and likely you aren't, working to extract carbon on a massive scale. Industries are. And these industries got elect officials in their pockets. And even if they'd crash, some Arab oil princes wouldn't wanna lose all their assets.
