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 fingerprints of Russia and Saudi Arabia are all over the decision text in Brazil. But a group of nations led by Colombia and the Netherlands offer hope

COPs have been collective failure probably since #1. I've been following since #20 and were total shit and somehow managed to get shittier.

We can't pretend petrostates will play nice. We can't pretend power hungry countries will act in any way but short term greed under the maximum power principle.

We are going to have to work in trade blocs. Basically, countries that don't meet climate and environmental standards get tarrifed/embargoed from large trade blocks of compliant countries.

While I share the sentiment that not enough is being done and ambition is lacking, the COPs and their agreements are important instruments that slowly progress. Without COPs (to the UNFCCC) or something similar it would be a handful of states spreading their ideology, but nothing or very little would be done.

How I see it; even though it is a game of pulling ropes, it is the best option we have (for global action). We will progress some each year, but it is dramatically slowed down by a group of states opposing strong measures. It is the reality of democratic cooperation (they always aim for unanimity).

But very little or nothing is already being done. The COP has been coopted by oil executives, lobbyists and petrostate ministers. I suspect it is now more a vehicle for obstruction of progress than achieving anything. The last couple of years have been exceptionally disapointing.

History offers us a rough sketch..

I think the only way to save the earth is by abolishing capitalism as practiced in most countries. And that cannot be done either through votes or conventions like cop.
