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.

Climate change is embedded in the history of colonialism and capitalism. Reflecting on this history allows to better understand the carbon market.

Coal and colonialism

The science unequivocally says that burning fossil fuels is the leading cause of the climate crisis. Based on historical and per capita emissions data, a comprehensive study estimates that industrialised countries in the Global North are responsible for 92 per cent of the excess emissions driving climate breakdown. Not everyone in the Global North is equally responsible, however. Just 75 investor-owned companies are responsible for about a third of worldwide emissions, and just 125 billionaires emit 393 million tons of CO2 each year. That is more than the 2022 emissions of Chile and Argentina combined.
