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.

Fuck formula E and Formula 1 for that matter it's always transform my city into a shithole when those event happen anyway what the use of better for climate car when half the people who come to thos event take corpo plane to come see them

Not to mention the huge diesel trucks, airplanes and boats that are required to ship the untold thousands of tonnes of cargo to and from each and every race.

Isn't tire dust the current biggest problems with cars? Can we do something for that, too?

[–] sonori 3 points 5 months ago

Tire dust is a problem, but i’m not sure it counts as a very big one when compared to the sheer scale of the damage to both people and ecosystems climate change will do. Between ocean acidification and the subsequent collapse of marine life, more frequent and intense hurricanes, floods, wildfires, and droughts, it would take a lot for microplastics to enter the same scale of devistation wrought by over a hundreds of millions of cars dumping more than five metric tons per year of CO2 into the atmosphere.

To reduce microplastics in North America your looking at fighting the car obesity ecidemic, improving tire lifespan, convincing people to be more gentle on the accelerator, fixing the god forsaken mess that is trying to ship anyone less than a thousand tons of aggregate by rail, and of course reducing the number of people who try and use a car to get around a city by expanding rapid rail transit/ increasing telework opportunities.

Outside of maybe some incidental improvement in tire lifespan and chemistry though, I’m afraid I really don’t know how you expect a raceing circuit to be able to help with any of the above.

That would require investment in public transport, and completely redesigning most (US) cities.

Not to mention increasing dependency on rail delivery for cross country goods.

[–] msage@programming.dev 1 points 5 months ago

Sure, though I wanted to coyly suggest that the most climate-friendly formula would transcent tires, too.

I don't think anyone is watching Formula E at all.

[–] silence7@slrpnk.net 8 points 5 months ago (1 children)

Telling people about it is a way to change that

[–] aniki@lemm.ee 1 points 5 months ago

But who are you going to tell? Formula 1 is already one of the most popular 'sports' worldwide, and I doubt you're going to find normies that are interested in Formula E that are not already a fan of Formula 1.

I like the way the pit stops are car swaps.

This is the only thing I know about formula E.

I feel like they should be doing battery swaps or something. Switching cars isn't going to drive the industry forward. I'm happy Formula E exists though. It's a good start.
