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.

Yeah I thought about quoting the rest of that line ...'which would cover the world's energy needs for several hundred million years' but didn't feel like converting that to hours.... 10^6 x 10^9 x 10^x x 10^6 * ~8765.... it's a lot of energy

You don't have to convert anything.
My comment was just to make clear that GW is for mesurement of power, whereas GWh is for measurement of energy.
As your quote was dealing with energy, but using Gigawatts as unit, there was something obviously wrong.

I've made it a habit to point that out in the hope of helping to make people realize the difference.
