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.

Can’t wait to see the articles in 10 years about how major countries are phasing out coal in the next 10-20 years.

The US still has work to do but have you SEEN the decline in coal use here over the past 15 years? Right now I think the US is back to using the same amount of coal that it did in 1965! As a percentage of energy use it's at the level it was in 1949!

Coal use in the United States absolutely fallen off a cliff since 2008.

The optimist in me is pumped about those stats, but the cynical pedantic asshole in me wants to point out >0≠0

Mostly I was just commenting on the fact that I keep seeing articles every few years about how some country or other has gone back on its promises to cut X by Y percent.

Thanks for sharing the facts, though! My cynical side needs to see stuff like that to keep it at bay.

The progress isn't reported on nearly enough and it leaves people feeling cynical and hopeless.

It isn't just burning coal either as US Production of coal is also down nearly 60 percent from its peak.

I'm still not sure we can get them ALL turned off by 2035 but we are on a clear long term trend-line of coal reduction.

The journey of a thousand miles begins with the first step. We might get there, and we have to start somewhere.

I hope I'm wrong about reading the articles again.

That’s cool, but the Rio 92 Earth Summit happened 16 years prior to 2008.

The whole two steps forward, one step back just hasn’t cut it.
