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.

The only problem will be the right wingers who complain.

Here in Australia, many trainee pilots actually fly near a coal power plant as part of their first nav training. You can smell it LONG before you're anywhere near it. I seriously don't think people realise just how bad Coal is, and how far the pollution stretches for (if they did, they'd immediately change their mind and want to dump it)

I used to live close to a coal power plant in Germany and there were never any smells, so now I wonder don't they use filters in Australia?

You don't notice them on the ground. But, up in the air in a light aircraft, you can follow the smell long before you can see the power plant
