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.

6th highest emissions per kWh of electricity produced in EU (1): 380g per kWh.

US: 370g per kWh.

France: 56g per kWh.

Sweden: 40g per kWh.

Which shows how far along the EU is in terms of clean tech rollout. Also your numbers are from 2023. With more renewables, less coal and more gas German emissions should have fallen rather quickly.

Pro tip: These numbers are probably from Electricity Maps. That site is apparently run by nuclear fanboys who apply the very lowest gCO2e/kWh for nuclear that they could find. Otherwise, France (and Sweden) would have higher numbers somewhere in the 100-200 gCO2e/kWh range

2nd source (Eurostat and European Environment Agency) corroborates the first: https://www.eea.europa.eu/en/analysis/indicators/greenhouse-gas-emission-intensity-of-1

Like what amazing technology did France apply, since I know they don't have geothermal power. Like what can produce energy with such low emissions. Why is the world not simulating this

Nuclear, however they keep having problems with it because it's so phenomenally expensive in comparison to renewables (they often buy from Germany in times of overproduction), too hot weather, not enough water… and then there's the problem to get enough refined fuel rods, since the biggest seller of those is indeed Russia.

The 2023' numbers of Germany were indeed awful (worsened by those LNG terminals and other emergency measures due to Russia's invasion in Ukraine), it gets better quickly though. The Green Party is doing its thing; we just have to hope the next, probably far-right government doesn't undo all of this progress like we see in other countries.

10% of yearly electricity production in France comes from hydro (1)
