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.

Are you sure about that? I’ve read that that the main source of heat / temperature on earth is Sun. CO2 is produced mainly by oceans and it is a derivative of temp. Human activity is responsible for maybe less than a 1% of all CO2 emissions. And this was proven years ago. Also - on the scale from my link a million years is like maybe a pixel, so are you sure there were no short periods (50-100 years) when temperature changed rapidly?

Are you serious? I'm not sure you're arguing in good faith.

Yes the energy, comes from the sun. More of it stays in the atmosphere because of CO2, making it warmer.

Yes, human CO2 emissions only make up a small percentage of total CO2 emissions. Nobody is denying that. But the natural emissions are part of a cycle that is stable. They get reabsorbed.
The relatively tiny amount humans added to the atmosphere (about 100 ppm since the start of industrialization) still has a huge effect.

That link actually debunks a climate skeptic claim, have you even read it? It does not support your claims.

CO2 lags behind temperature changes, not the other way around. It can later amplify the changes.

No, that's not what it says. Yes CO2 increases with temperatures. But it's also the other way around.
