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.

Of course they did. This is one of issues with our models of democracy, that may be quite difficult to solve.

Politicians and their parties have 4 or 5 years to introduce new and alter existing legislation, sign contracts with companies and agreements with other countries. If they don't do anything for 'now', and focus on the future - people won't vote for them anymore.

When one party promises improvements in 6 months, people will always choose it over a party that promises a stable and healthy environment in 50 years. Of course, the first one lies. But those lies work and get votes. So what do you do?
