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.

Meeting climate goals has to create an actual advantage for countries or well avoid them punishment from the international community. Blind cooperation is nice in theory, but it just does not work in practise. So we need proper funding from the wealthy countries, maybe leveraged from tariffs based on historic emissions, which then can go to poor countries, which only recieve the money, if they meet certain targets like stay below emission per capita levels or new fossil fuel infrastructure. At the same time we need to punish current emissions. For that systems like emissions based tariffs would work well. Other things can be done in trade agreements as well. I really like tariffs here, because they create a real monetary insentive for good action and that is kind of what works.

But be nice to China, otherwise they kill the planet is not going to work. Same story for the US and every other country on the planet. Nice words from politicans do not save the climate.
