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.

Rightwing thinktank Civitas mistakenly cost onshore wind power 10,000 times higher than reality and claimed bill would be £4.5tn

They did this shit with "calculating infrasound from windmills" in Germany 20 years ago. They (a government and lobbyist financed org) were several orders of magnitudes wrong but took a very long time admitting it.

As some German celebrity said: "It's hard to save the world in your spare time when others are paid to destroy it full time"

Feel like its a common mistake to mix up kW and kWh, but if you don't know the basics of power you shouldn't be trying to write on the topic and any peer reviewer should know the cost of onshore wind is in the cents per kWh, not 100's of dollars per kWh if someone has even if only from paying attention to their own electric bill.

Also apparently mixed billions and trillions at one point? Just a small factor of a 3 (orders of magnitudes).

Yeah but that doesn't support their narrative
