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.

Before the Paris agreement, humanity was on track to cause a potentially catastrophic 3.5°C (6.3°F) global warming by the year 2100. Currently on track for ~2.5°C (4.5°F) warming by 2100 (yaleclimateconnections.org)

Biden brought the US back into the Paris agreement on his first day in office.

Ahh the US, the country where international accords are more of an on/off thing, depending on the election cycles mood.

Speaking as a US citizen, you aren't wrong. I wouldn't make agreements with the US unless it is February of an odd numbered year.

ETA: Late January of odd years is when we get a new president or a new Congress. I say February so there is time for the transition.

Thank you for the follow up. I probably should have added that.

Didn't mean to sound passive-aggressive, sorry if it came across that way. I just don't want people to throw their hands up in despair. We need to fight back, and know that fighting back works.

Eh I didn't catch it that way. I just wanted Americans to have the facts. You're right, the way I wrote it seemed pretty defeatist, considering I left out that we reaccepted the agreement.

But this is why the fediverse is supposed to be great. You filled in more facts for me that I failed to include! Now hopefully others well read this and be more informed! 😁

I really appreciate this rational, reasonable exchange. Thanks for giving me hope for humanity, you two.
