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.

My impression is that this is a PR push, designed to avoid having to invest in renewables, and let them keep on burning gas and coal, rather than something likely to come to fruition.

The Ghanaian government is set to repeal its controversial pro-mining legislation, following weeks of demonstrations against environmentally disastrous mining, including the threat of a nationwide labor strike.

In November 2022, the government issued LI 2462, a directive allowing mining in forest reserves, including biodiversity hotspots. Mongabay previously reported on how LI 2462 threatened to exacerbate the extensive harm from mining to Ghana’s environment. According to the Ghana Institute of Foresters (GIF), mining leases were granted over about 390,000 hectares (964,000 acres), a fifth of the country’s forests, in the year following its passage.

We’ve only had 1.3C of global average warming, but it’s enough to popularize the entire category of personal cooling devices. So when people say, “You won’t even notice 1C of global warming,” the market tells us that that’s absolute bullshit.

Meanwhile in North America, Canada's VIA is operating on a shoestring and being further threatened ... and in the last 50 years the US has pulled up most of the rails that were installed in the previous century. We're stuck with airplanes, hybrid metro-transit, and what's left of Greyhound. But, hey, we've got a world to police!

The climate movement has been led by people who look and think and talk the same for a very long time. If time is short, isn't this precisely the time to try everything? To broaden out, seek fresh ideas, build a larger, stronger and more connected movement?
