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.

‍2025 has been a disastrous year for climate science in America. The 47th presidential administration has fired hundreds of scientists, starved programs and departments of funding, rolled back dozens of environmental regulations, undermined the tracking of hurricanes and extreme weather, and has taken down hundreds of federal websites, pages, references and data sets related to climate change. This ideological purge of climate research aligns closely with the goals of the Project 2025 Mandate for Leadership.

There are some great organizations working on archiving this data, including the Public Environmental Data Partners, The Data Rescue Project, and the Southern Environmental Law Center. We're adding our site to the pile, as the more of us that download and share this information, the harder it will be to suppress.

Since most people won't be combing through these spreadsheets, we've also mapped several of these data sets, and provided commentary to help make sense of this data. You can view those here:

We've also compiled reports from both public and private institutions, as well as research papers with a focus on climate resilience and adaptation. If there are any reports or data sets you think we've missed, let us know and we'll add it to the collection!

The Democratic party and the climate movement have been “too cautious and polite” and should instead be denouncing the fossil fuel industry’s “huge denial operation”, the US senator Sheldon Whitehouse said.

“The fossil fuel industry has run the biggest and most malevolent propaganda operation the country has ever seen,” the Rhode Island Democrat said in an interview Monday with the global media collaboration Covering Climate Now. “It is defending a $700-plus billion [annual] subsidy” of not being charged for the health and environmental damages caused by burning fossil fuels. “I think the more people understand that, the more they’ll be irate [that] they’ve been lied to.” But, he added, “Democrats have not done a good job of calling that out.”

While Whitehouse slams his fellow Democrats for timidity, he blasts Republicans for being in the pocket of the fossil fuel industry, an entity whose behavior “has been downright evil”, he said. “To deliberately ignore [the laws of physics] for short-term profits that set up people for huge, really bad impacts – if that’s not a good definition of evil, I don’t know what is.”

To be clear, "ignoring" doesn't mean doing nothing; the Democrats actually passed major climate legislation that was then dismantled once the Republicans took power. It mostly means that they're not campaigning on it right now.

New preliminary research suggests that a combination of higher atmospheric CO2 and hotter temperatures contribute to a reduction in nutritional quality in food crops, with serious implications for human health and wellbeing.

I'll note that the converse also applies — because warmer air can hold more water, it can remove more water through evaporation too, so droughts can also end up being worse.

Summers have been heating up for decades, and they’ll only get hotter if heat-trapping pollution continues — making future summers in Minneapolis feel more like current summers in Tulsa.

With high levels of heat-trapping pollution, future summer high temperatures in 247 major U.S. cities would heat up by an average of 3.6°F by 2060 and 7.9°F by 2100. This analysis shows how future warming could transport a city’s current climate to an entirely different part of the country — or the world — with reduced commitments to lower carbon pollution .

On average, summer high temperatures across the 247 cities analyzed are projected to increase 3.6°F by 2060 and 7.9°F by 2100. Mitchell, S.D. is projected to warm the most by 2100 (11.1°F), when it will feel more like Wichita Falls, Texas.

By the end of this century, summers in the cities analyzed would shift to resemble hotter locations an average of 437 miles to the south. For 16 U.S. cities, there is no equivalent in North America to how hot they’d be in 2100. Their future summers are more similar to current conditions in Pakistan, the Middle East, and North Africa.
