Climate - truthful information about climate, related activism and politics.

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.

You're getting carrying capacity, carbon capture and carbon neutral confused, which then flows into sustainability.

Carrying capacity isn't about getting it back or stored - its the environments ability to "carry" our waste products without long term damage or effects. Increases of forest - pine or mature native - does indeed increase the earths carrying capacity for carbon emissions, waste water, runoff and other areas. You're right, pine doesn't mean long term carbon capture but that's not this arguement.

Regarding burning waste that otherwise cant be used - yes it is greenwashing. We used to think the same thing about burning or dumping rubbish- can't use it so let's just burn it. Admittedly this is a much more complicated problem and reverts back to a complete circular economy requiring a significant change in design, ways of thinking and culture to eliminate this one - but it can still be done.
