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.

New compact SUVs now create less pollution, on average, than sedans, thanks to the rapid rise of small electric SUVs. (wapo.st)

The picture would of course look very different if manufacturers had chosen to make smaller inexpensive electric sedans.

I have the same problem with big cars. At the moment I have an ageing Toyota hybrid saloon, which is as big as I want to go. Years ago I knew a couple of people who had Toyota Rav4s - they were chunky little 4WDs, with a high wheel base but a small footprint. Perfect for the places I drive! Toyota still makes a Rav4, but now it's a bulging, bloated monster. I'd love to have the original Rav4, but electric.

That is such a shame. I would have loved a smaller RAV4 if I needed to drive up in the mountains. (My little Corolla struggled the few times I visited.)
