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.

On BBC’s HARDtalk 5 years ago, Roger Hallam was slammed across the board for saying billions of lives were at risk. The liberal climate movements tried to refute and play down the existential risks ahead. The last few months have shown ever more clearly that he was right. After all, what do we actually think the “end of civilization” will look like?

Several new scientific papers from Ripple and Pearce have outlined that not only are billions of lives on the line, but that “richer humans will be responsible for [the] killing”. This month, the NASA Climate Scientist, Peter Kalmus, also added his voice to that position. The time for shying away from our existential reality is over. The precautionary principle dictates that these realities form and guide the mission of our lives - that only a revolution to change who makes the big decisions is going to save us.

Remaining within “the law”

The second new development is that 4 Billion Dead will not be involved in organising or acting in a way a regime sees as illegal. In the increasingly authoritarian contexts we face, direct action will most likely lead to the arrest and imprisonment of people in the organisation and force its closure. 4 Billion Dead as an organisation will therefore focus, for the time being, on training, the organising of the processions, and publicising the 4 billion death reality we face.

Okay, bets on how long it takes for what they're doing to be "seen as illegal" by the UK executive?
