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.

Researchers quietly planned a test to dim sunlight. They wanted to ‘avoid scaring’ the public. (www.politico.com)

"More clouds" should not be controversial.

It is if it involves using fossil fuels to run aircraft to do it or the cost would result in better returns elsewhere like with insulation or if the process is putting chemicals in the air not naturally there or if it increases we bulb temperature. etc. etc. fucking with things in hopes of effect as not as effective as doing things with known actual beneficial effects. Its like carbon capture. If it produces more co2 than it captures it is a non starter.

Guy pushing chemical-industry paint subsidy performatively strokes chin.

The fuck is insulation supposed to do for greenhouse gases?

[–] HubertManne@piefed.social 1 points 1 hour ago (1 children)

insulation reduces energy usage for heating and cooling and I assume the first part was sarcasm.

My guy. Nudging your thermostat is not gonna make the wiggly line in the sidebar go back down.

Stopping sunlight from reaching the ocean, will.

[–] HubertManne@piefed.social 1 points 1 hour ago (1 children)

8 billion people nudging the thermostat will have a much greater effect than artificially increasing clouds and won't cost any energy and cause more global warming as part of the process. Its a one and done. Even at 1 billion and even at 100 million.

Increased cloud cover could cause another ice age.

If we stopped all human energy use, immediately - the climate's still in deep shit.
