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.

It did vanish overnight!!! Go read up on how fast they disappeared. Yes numbers have been declining but we hit a catastrophic temp event that killed millions of crab.

They starved. It doesn't take long for a crab to starve.

It's worse than that. The snow crab population is close to 10% of what it was in 2009. The point is, this isn't the first time there was a major decline in the snow crab population. It's been dramatically but consistently plummeting over the last decade.

The crab population only 'halved' in 2019 because of a small resurgence in the population in 2018. In reality, the crab population is back on its usual course of being completely screwed by climate change.
