Getting reelected would be nice, but the administration also needs to guard against the damage a second Trump administration could do to the environment. Here’s how.

    How bad things get is literally a matter of degree.

    We can’t achieve no impact, but temperatures will stabilize fairly quickly once we stop adding CO2 and other greenhouse gases to the atmosphere. Getting there isn’t something that happens overnight; in the best case, it looks like a 20-year phaseout of fossil fuels and end to deforestation.

      But the damage we’ll cause during those 20 years will destroy most of the ecosystem and our food supply chain. I have a feeling that the biggest reason behind stopping emissions will be our demise.

        There will be some damage, but probably not end-of-civilization kind of damage if we actually cut emissions by a few percent of current emissions each year

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.
