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.

It might be more efficient to tell us what he was accurate about

If anything he said was factual i'd be surprised

A big lie, or at least non sequitor, in his declaration of war on Europe (not in NYT or other fact check sources) was

Europe reduced its own carbon footprint by 37%. Think of that. Congratulations Europe. Great job. You cost yourself a lot of jobs, a lot of factories closed, but you reduced the carbon footprint by 37%. However, for all of that sacrifice and much more, it's been totally wiped out and then some by a global increase of 54%

Europe reduced its own carbon footprint by 37% relative to 1990 levels. They also reduced their coal and NG use in electricity sector by over 20% each just in the last 2 years, as their electricity consumption grew about 10%.

Relative to 1990, China and India have increased emissions significantly (5x). China is world's manufacturing hub, and even with near 9% electricity consumption increase last year, managed to reduce electricity sector emissions. China built more new solar in first 6 months of this year than exists in US for all time. India had planned its energy transition around 200gw of domestic solar production capacity by 2026. They will not be buying US energy, and if they simply don't have the technical expertise to complete their ambitions, a Chinese investment deal is likely very soon. India is more important than US (lost cause) for energy transition, and every country that doesn't have an oil oligarchy is not stupidly going to maximize their enslavement to geopolitical scarcity, extortion, and needlessly expensive climate destruction.

The total lie portion is that emission reductions happen from renewable growth rates. There has been global/China success in achieving extreme production rates, that can keep growing from here. So, the verge of massive global emission reductions is upon us. Of course US response is that we must choose cannibalism instead of human sustainability.

The non sequitor portion is ok... Europe did good, world did bad over a 30 year period, but the relevant part is recent progress and opportunity. Why does US want to stop all progress and hope? While believing in its own pure BS/propaganda for dead ender energy, none of its companies are investing in, and rely on enslavement of "allies"/colonies to enforce climate destruction?
