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.

Land of the free, home of the inefficient: appliance standards as culture war target (www.npr.org)

From ceiling fans to refrigerators, the Department of Energy is updating appliance efficiency standards that would affect millions of consumers.

The Biden administration's goal is to reduce climate-warming greenhouse gasses and save Americans billions of dollars a year in utility costs. But the administration is facing pushback from the natural gas industry, because some new standards would affect gas appliances. Conservative politicians and media have taken notice of the measures, too, and they've now made unsexy, technical appliance standards a flashpoint in the country's culture war.

I don't think I've seen those huge increases except on appliances with greatly increased capacity as compared with the old ones. I don't think it's a big deal either; you set up a washing machine or a dishwasher, and then you go do something else. Almost nobody sits around babysitting their washing machine or dishwasher.

I'll also note that the appliances also have a 'speed' cycle which runs fast for those rare occasions when you need it.
