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.

This is what you would expect if it were run by someone from the fossil fuel industry...oh wait:

What a surprise! .../s But the Loss and Damage fund is a very delicate issue, was progress even to get some countries to agree the concept exists. Seems to me, that the "developing" countries are right about the 'World Bank' issue, but fundamentally wrong to insist on retaining 1990 definitions of country groups, the situation changed enormously over 33 years. For example the per capita emissions of China are higher than the european average for many years now, and those of the Arabian gulf are the highest in the world. The impact on the atmosphere depends on historical emissions, but not on their simple sum - there is a decay over time as most of the CO~2 ~ goes into the ocean and other sinks. Unfortunately the subtleties of such science don't penetrate to those 'high' level discussions (been there, tried that).
