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.

Net zero emissions by 2050 is great for the fossil fuel industry (johnmenadue.com)

If national governments across the globe are prepared to put minimising the climate threat ahead of protecting the fossil fuel industry, they will have to make major changes to how the net zero concept is being applied. This will require carbon offsetting to be brought in line with its intended application, and a consequential major reduction in its use.

The global objective should be to phase out fossil fuels as quickly as responsibly possible. Instead, the objective appears to have become how to achieve net zero emissions by 2050 without phasing out fossil fuels! It is hard not to think this has a lot to do with the power of the fossil fuel industry.

Anyone who thinks "Net Zero" is realistic without banning all fossil fuels is living under a rock. Unless we magically figure out how to make CO2 disappear we're screwed, we're too far down this road to turn back by regular means.

I read

[...] to turn back to regular memes.

and I am ashamed of myself.

Net zero is antithetical to the existence of fossil fuel companies, save for some amount of natural gas in niche scenarios & space exploration. Carbon offsetting will be greenwashed just like the recycling push of the 2000s. So will simultaneous carbon sequestering. This reads like a tabloid from the 50s saying smoking isn't bad for you.
