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.

We know our planet’s ecosystem is breaking down…much of the destruction is irreparable. So, why haven’t things changed faster?

Because money. People can’t afford to upgrade their lifestyle to solar panels and organic foods and a new electric car. Corporations aren’t going to stop making things out of plastics and poisons if it costs them more profit.

A lot of people can afford it, and aren't. They're buying luxury instead.

Because lot of people got rich by being selfish assholes, so you can't really expect them to change now. But some people can afford it and are.

Just saw this graph in neighbouring comment.

It is not going down, but at least it stopped going up in last 10 years. So something is happening.

It will take time. I drive 10 yo ICE car and I can't afford new ev car now, but hopefully before my current car will die in 5+ years, second hand ev market will exist.

Most emissions are caused by rich people. Quite frankly as soon as you forget about the car, the rest is rather cheap. Solar panels powering a home are not crazily expensive and organic food staples are also not that much more expensive then the conventional competition. Electric cars are expensive, but the proper choice is to try to live car free anyway. A bicycle is cheap after all.

Anybody who actually is emitting more then the global average can live in a way that massivly reduces their emissions and afford to do it. Not to zero, but to a point, where it is absolutly reasitic to demand companies and governments to push for the rest.
