To be clear: there's a night-and-day difference between Biden and Trump, with the former having actually taking significant action, and being likely to take more if reelected. Trump will look to maximize both extraction and consumption of fossil fuels in a way that Biden simply didn't and won't.

If you think there is any comparison here in terms of magnitude, you should probably go have your head checked.

[-] bionicjoey@lemmy.ca 7 points 9 months ago

Agreed, but magnitude doesn't matter when the climate crisis is a binary outcome. Either we stop it or we don't. Neither candidate is willing to take the action needed to treat the climate crisis like the existential threat that it is.

The climate crisis is an ongoing gradient of "this is bad" to "humans are extinct" and every tenth of a degree we can prevent is worthwhile.

[-] bionicjoey@lemmy.ca 2 points 9 months ago

We don't prevent degrees though. The temperature is steadily increasing. At best, we delay degrees.

Unless we actually stop increasing carbon emissions (which we aren't doing right now), we're fucked.

Marginal gains add up to the changes we need. All or nothing thinking will kill us all.

[-] RenownedBalloonThief@lemmy.ml 1 points 9 months ago

As opposed to the level of change Biden is willing to accomplish which... will still kill us all.

You mean like this piece of legislation he pushed through, which is basically the first major bill in the US which addresses climate change? https://earthjustice.org/brief/2022/what-the-inflation-reduction-act-means-for-climate

[-] rigatti@lemmy.world 11 points 9 months ago

Pretty sure it's not a binary outcome. We already have warming at levels that is detrimental, and we're not going to stop it. All we have left is mitigating actions.

[-] apt_install_coffee@lemmy.ml 6 points 9 months ago

But it's not a binary "we're fucked" or "we're fine", it's an ever worsening gradient of terrible conditions. Even within that, how many people get the brunt of it depends on the extent of the damage.

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.
