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.

The "3.5% rule" needs protesting (www.theneweuropean.co.uk)

A note of caution about the 3.5% rule that has received a lot of focus in recent years:

People will, of course, find reasons to explain away why one or the other of the protest movements don’t count – but what’s important is that both show there is nothing magical about a 3.5% threshold, even in exactly the context to which it was originally applied.

The animating theory of modern protest, then, has been extended well out of the context of its original research, and doesn’t hold up even in its original context when we look at the biggest non-violent protest movements of the last decade. And yet this goes entirely unexamined.

The two examples they point to share an obvious commonality that doesn’t apply to the climate movement. Both protest movements were brutally suppressed by a much larger and more powerful external force. If the protests has been across all of China or Russia I am sure the outcome would have been different. But 3.5% of Hong Kong or Belarus are both small compared to China and Russia.
