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.

I understand that. My point was that even using words like phase out is still giving too much weasel wording. Just set numerical targets and if countries want to try to meet them with carbon capture that is their prerogative.

if you use numerical targets it forces the companies/countries defending fossil fuels to reckon with the infeasibility of carbon capture. They will be disincentivized to do something that only gives the appearance of being helpful while not actually helping that much if they are penalized for failing.

At the end of the day all that matters is net carbon emitted comes down and eventually goes negative. it ends the endless debate about fossil fuel discontinuation. If they can make it work good for them, while the rest of us will switch to renewable.

Of course numerical targets would be best, but if they can’t even agree that they need to get rid of fossil fuels than it’s going to be hard to set thouse targets.
