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.

Relevant article that talks about Cop29 in relation to previous ones: What should we expect at COP29?

Last year at COP28 in Dubai, countries agreed to “transition away” from fossil fuels for the first time ever.

But the ‘UAE Consensus’ was less a consensus and more of a watered-down pledge, leaving many advocates disappointed as no promises were made to fully phase out oil, gas and coal.

This outcome was likely shaped by the presence of thousands of fossil fuel lobbyists at the event, which was itself hosted by a petrostate and led by the CEO of a state-owned oil company who openly dismissed the need for a fossil fuel phaseout.

I expect nothing and I'll still be disappointed when it's over.
