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.

Friendly reminder that the IPCC models have consistently been conservative in their approach, mainly because the reports are influenced by policymakers and a biased committee before they reach daylight.

You can look this up yourself, there is plenty of criticism from the scientific community.

IIRC the AR6 said it had high confidence that we would not reach 1.5c before 2030 and medium confidence we would reach it around 2035.

Because of this I want to say that the 1.5c limit is an arbitrary bullshit number for policymakers to appear as though they're aiming for a goal.

There is no safe level of warming, and a large amount of these feedback loops have and may happen because of factors other than ONE fucking number. (E.g Human influence on the Amazon)

We're looking at possibly hitting 2c warming by 2029 now.

Business as usual, Venus by Tueday. What a time to be alive, lmao.
