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.

No one alive will experience a better climate than we have today. But young people will experience a much more dangerous and chaotic world in the future.

If you add up the current CO2 level of 424ppm, the effect of CH4 and the other greenhouse gases (+100ppm), and the effect of “albedo dimming” (+100ppm). Then we are at a level of +624ppm(CO2e).

That’s about +6.5°C over baseline according to the paleoclimate record. The one that mainstream climate science DOESN’T use to calibrate CO2 levels to global temperatures from but that their “new numbers” for climate sensitivity are starting to match.

If the Rate of Warming follows the pattern of the last few years. Then La Nina years should warm about +0.1°C per year. With “spikes” during El Nino years of +0.2°C up to +0.4°C PER YEAR.

With 2 El Nino’s per decade and about 6 La Nina years we may be looking at a RoW of roughly +1.2°C of warming PER DECADE now.

Guess I'm going to kill myself. This shit is fucked up.

How should I kill myself, any recommendations?

If you wait long enough climate change will do it for you.
