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.

Stop spreading disinformation.

We had (and still have) a dangerous man-made ozone deficit in the upper atmosphere of the arctic regions.. It was caused by certain chemicals used in refrigeration, CFCs. We stopped using and producing these chemicals and the stratospheric ozone layer is recovering now.

The stratospheric ozone layer is vital for life on Earth's surface because it shields us from an excess radiation of UV light from the sun. The ozone depletion problem was already so severe that it had effect on wildlife in higher latitudes.

All this about ozone in the stratosphere, a very high layer of the atnosohere.

Ozone in the ground is caused by photochemical smog and is toxic for animals and plants. It is very harmful to our lungs.

Saying these are the same things is plain disinformation.
