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.

Americans can achieve even more by helping to get others to vote

Opponents — including plenty of former global warming deniers who have rebranded themselves as economic pragmatists — have cast these steps as too ambitious, too costly or both. Which is to say, we can’t afford to save the planet.

To put it as soberly as we can, it’s that same old suicidal nonsense recast to pass for common sense.

A brilliant, introspective summary of how single-issue voting got us here and how it won't save anyone.

The system sucks, but please, be pragmatic. Vote for Harris, hold the Dems accountable, and donate to STAR and Ranked Choice Voting initiatives in your area to avoid this dilemma in the future.

Twenty years ago, I made a choice that left the world a distorted echo of what it could be.

Twenty years from now, you too will reap what you sow.

But now, a study sheds light on what’s driving record methane emissions. The culprits, scientists believe, are microbes — the tiny organisms that live in cows’ stomachs, agricultural fields and wetlands. And that could mean a dangerous feedback loop — in which these emissions cause warming that releases even more greenhouse gases — is already underway.

Americans: Besides voting for Harris, I recommend also actively volunteering

TLDR: Pasture in former forestland, such as New England, can quickly be returned to forest, soaking up carbon. There is an interesting opportunity for synergy here, as removing cattle from a relatively small amount of land can have outsized impacts compared to the larger grazing areas in the prairie by pairing the removal of cattle with reforestation. These high opportunity areas could be a highly effective investment and much more financially and politically feasible.

The devastating flooding should spur this month’s Cop29 climate conference to press for immediate action, not look away

I do not believe this includes scope 3 emissions.

A second Trump administration could stop defending the E.P.A. against lawsuits attacking its climate policies. Other effects might be more far-reaching.

If you want to stop him, it's going to mean not just voting for Kamala Harris but volunteering to help get others to vote for her as well.

The difference is pretty stark. Americans who want to make a difference, it's important to not just vote for Harris but actively volunteer for her campaign
