Climate - truthful information about climate, related activism and politics.

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.

I don't think hyperbole like damage lasting for millenia is worth much. People don't think in such terms and the only people who will listen to that are those who are already on the side of climate action.

The articles call to arms is right, but this is not the way to beat trump. Instead of damage for millenia, the focus needs to be on convincing people that his short termist policies will damage then financially and personally.

Instead of cheap renewable electricity he wants to use voters tax money to subsidies and promote fossil fuels. Instead of clean cars in cities and towns, he wants to choke you and your children with petrol fumes.

An image of trump in a jacket covered in fossil fuel company sponsorship logos, and trying to force an exhaust pipe down a child's throat is the kind of thing that summarises his position. We're not trying to convince die hard republicans, just the moderate centre / undecideds that trump will harm them and their children directly with his policies, let alone millenia of damage.

Whether Trump or Harris wins, the US military is still the single largest institutional emitter of greenhouse gases in the world.

Will global warming be accelerated under Trump? Yeah, probably, but the problem is here and now. Without addressing the US military complex emissions and billionaires taking space walks, the speed is a relatively moot point.
