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.

If Americans want to keep policies we have in place (and do better) it's going to be critical to re-elect Biden and send more and better Democrats to both houses of Congress.

For Americans, that means:

Don’t get me wrong, Trump would be terrible for the environment and climate change, but saying that it might be a stretch to say he would be able to repeal all the policies listed in the article. (Then again, the last Trump presidency was wildly destructive, so who knows).

1 & 2: EPA rules on coal and gas and tailpipe emissions: the EPA has intentionally announced these pretty early so they wouldn’t be subject to the Congressional Review Act (CRA) making them harder to repeal quickly. Trump also can’t unilaterally repeal them, just like how Biden couldn’t unilaterally execute them, they have to go through the EPA rule making process. The power plant rules face significant threats from the courts, but less so from the executive. Similarly for the vehicle emissions standards, and those have the added benefit of being similar to rules adopted by states, which means that even if they are repealed federally, car companies will still have to comply with them in several major markets (e.g. California).

  1. The IRA: So much IRA money has already gone out that it’s a pretty durable piece of legislation. Big moneyed players have invested a lot because of the legislation, and they don’t want to see it go away. Trump is clearly in the pocket of billionaires, so it could be hard to repeal. It’s also huge, so even if piece of it are undercut, the law itself could stay more or less intact.

  2. Oils and Gas Drilling: sure, Biden has made drilling for oil more expensive and building clean energy in federal land cheaper, but he head still leased a TON of oil and gas land, more than Trump in the first two years, so I’m not sure we’ll see huge changes there anyway! I don’t think the land that Biden has protected will be easily opened back up again, and it’s unclear how long the LNG pause will last regardless of the administration.

  3. Global Climate Negotiations: this is the big one. As with everything else Trump does, a second Trump presidency would set us so much further back in the global stage it’s ridiculous. The US is already a laughing stock for how un-seriously we take climate change, and while that has improved, a Trump reelection would tank us.

All of that to say, a Trump presidency would be disastrous for the climate, not necessarily because the progress made by Biden wouldn’t stick, but because we would stall here and have very little possibility of getting more done for the next four years, leaving us two years before our Paris commitments (god that’s a terrifying thought).

1 & 2 Four years is enough time to go through the EPA rule-making process. So Trump will do it to get rid of the rules. He did it before.

  1. Trump isn't just "in the pocket of billionaires" but in the pocket of specific billionaires, who want to get rid of it.

  2. Biden had a bad start, and then took new leases down to near zero after his first year:

  1. Yep.
