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.

Some things are easier to change than others - and the really hard things often don't require money, but a change in people!

Edit: Sorry for the shitty OP, I should have known better than to post in a hurry.

It reads as if the population is primarily responsible for combating the climate crisis, while industry and government are off the hook because money has little effect.

What I actually meant to express was that technological adjustments that only cost money are easier to implement than changes to people's habits. Perhaps this is a naive idea because it assumes that there is the political will to make these investments and that the industry is forced to cooperate accordingly. Addressing the climate crisis requires many changes, and economic profitability must be secondary. But achieving this is perhaps one of the most difficult adjustments society requires.

Why is decarbonisation of individual heating and electrify individual mobility not on a similar level? Seriously most people do not care where the heat comes from, but that it comes. Nobody is braging that they have the GasBoiler MilleniumXX at home. However a lot of people are really into cars and the sound and feeling of a combustion engine has been made into something cool by car advertisments. So people are going to switch to low cost green heating, if it is cheaper and practical. I do not see that for cars.

Maybe because people don't change their heating until it breaks, but plenty of people change cars often

Rich people yes. Most people buy cheap polluting cars and change them when they it's too expensive to repair.

[–] yessikg@lemmy.blahaj.zone -1 points 10 months ago

Yeah but in the USA, the too expensive to repair threshold is fairly low

I agree, people aren't as emotionally attached to their boilers. But while there are already plans discussed to phase out gas heating in the EU, for many buildings the cheaper and practical alternative has not arrived yet. That takes some convincing.

Electric cars need competitive racing like F1 and NASCAR. There needs to be a culture built around the power of electric vehicles to get the muscle car culture to switch. Make electric cars "cool".

There is Formula E. We also have some all electric super cars by now. Porsche has Taycan, Rimac is all electric and there are some other sports cars around as well.

That's awesome. Hope they start to make their way into the mainstream soon. I'm ready to go all-in on electric. Besides the climate, imagine what our cities will sound like with less combustion engines running.
