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.

We have technology to reflect heat into a wavelength that goes out into space. I would much rather we subsidize getting that on surfaces than something like this. Also just insulation. I mean there is a lot less controversial stuff that will be more effective.

"More clouds" should not be controversial.

[–] HubertManne@piefed.social 2 points 15 hours ago (15 children)

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 9 hours 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 8 hours 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.

and if everyone put a foot down on one side of the earth and took their foot up on the other the earth would spin out of orbit.

I was responding the preposterous with the preposterous.

You do not understand this problem.

Sending energy to space, as light, is your proposed solution. What do you think clouds do?

Exactly how much paint do you imagine is necessary, versus cloud formations that are visible from the moon?

[–] HubertManne@piefed.social 1 points 5 hours ago (1 children)

Cloud transformation is just that. When you doing it you mess with cloud formation at other places and times and you have to keep on sending up planes to do it. It can't do what you think it can do.

Cloud seeding is a different thing. This is about adding humidity to the air, from sea level.

[–] HubertManne@piefed.social 1 points 5 hours ago (1 children)

That was a future thing they wanted to do the first part is talking about seeding. Increasing humidity is not something you want eiher. Wet bulb will be bad enough.

[–] mindbleach@sh.itjust.works 1 points 4 hours ago (1 children)

They sprayed from the ocean, on a boat.

Even then: 'They were only planning it in the future.' Yeah, man. That's when plans happen.

Even then: you think more clouds here means means fewer clouds elsewhere... but this can alter humidity, globally?

Even then: do you understand wet-bulb temperature is also about temperature?

[–] HubertManne@piefed.social 0 points 4 hours ago (1 children)

humidity is global. Its part of the cycle. Its like thinking you can burn fossil fuel i the ocean and it would not effect other areas or it happening in one country not effecting another. Its essentially accelerating the cycle as the heated earth will increase humidity. Its like trying to get out a hole by digging deeper.

You're just shuffling cards. You don't even understand there's an argument happening.
