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.

It won't stop unless we also remove the greenhouse gases that we put there

Unless I misunderstood, the article claims otherwise.

Yes, net zero, which some companies and countries pledged to reach until 2050. Unfortunately it's delusional, because they count on technological fixes being invented in the future and until then it's "business as usual".

Industries like cement, chemical and steel will never be net zero without carbon capture for example.

Organic plant based cement is already a possibility, yet we're still using the good old mixes purely to avoid change

I feel like this is closer to the truth. Isn't there a theory that theres about a 2 decade lag between the CO2 (or equivalent) being released and the effects of heating?
