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.

Denial is over. Climate change is happening. But why do we still act like it's not? (theconversation.com)

I'm paying $10 extra on my intercontinental flight, so it's Carbon Neutral™

@KISSmyOS @rickdg if realistic, that would offset on average 1 ton of co2e, so at that rate it would only cost $150 per year per person in the US to render the US carbon neutral.

You know, if the deal on offer from politicians was "pay $150 a year and we'll stop climate change in its tracks" I'd go for it in a heartbeat.

Why do I suspect it costs rather more than $10 to *really* offset 1T of CO2e? :blobcatsadpats:
