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.

I personally think we need to leave geoengineering the hell alone.
We live any closed system where a change of climate in one area can drastically affect the rest of the system, that's why the polar ice caps are melting in the first place.
If we start deliberately messing with the climate, who knows what kind of hell we could accidentally unleash.
For example, the Amazon rainforest depends on dust from Saharan sandstorms provide nutrients as it's carried across the ocean, if we were to start a cloud seeding project in the Sahara and turn it green, that would be a sharp reduction in nutrients arriving in the Amazon which would cause the deforestation problem to rapidly accelerate.
We have no business fucking with the climate at all and we should be looking into eliminating the causes of climate change rather than looking for ways to live with them.

I agree in general but we may not actually have a choice soon.

Any proper (i.e. Real scientists leading it and not some start up pushing it for a hidden profit agenda) geo engineering project is going to be carefully studied, slow and methodical to ensure such things are properly mitigated.

Even this very article is about scientists calling for a study to see if it should or can be done at all. If it's determined it should or can, and it's being done properly, there will be multiple follow up studies to determine side effects and if they can be compensated for and what not

Yeah and we kinda need to start doing it soon. Because it might become a thing we have to do, and I'd rather we know how to do it and not just wing it.
