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.

Antarctica’s west coast missing an area of sea ice the size of France as temperatures peak 20C above average (www.theguardian.com)

A vast area of the Bellingshausen Sea should be covered by sea ice by now, with one expert calling the loss of ice ‘depressing’

It’s winter in Antarctica, when sea ice expands rapidly around the continent peaking in September.

But satellite observations showed the Bellingshausen Sea – on the west side of the Antarctic peninsula and which by June would usually be covered by ice – was almost completely ice free.

Because it's uniquely on the bottom of the earth unlike every other continent where east and west is trivial.

I think their objection is defining west or east to a circle on the south pole.

If I drop a hoola hoop on the south pole, what part of the hoola hoop is the western part? Which part is eastern? North and South are easy.

Fair enough. I just figured.. there's the 0° meridian and everything on the left of it is west and everything on the right is east. Same principle would apply to the hoola hoop except it would be hard to determine unless someone was nice enough to draw the line on the ground like they did in Greenwich.

To me north and south would be weirder because the south would be inside the hoop and north would be the edges
