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.

Those of us who care about climate change need to get off the mat and get back to work. There is still much we can do.

Stripping hundreds of millions of dollars from renewable energy and efficiency initiatives is part of a broader move to undo efforts to wean the United States off fossil fuels.

Fireflies are vulnerable to climate change and habitat loss. Some simple landscaping tricks and turning off porch lights can make a big difference.

Wealthy nations risk undermining the loss and damage fund’s plan to deliver $250 million in aid next year to climate-vulnerable countries hit by extreme weather, board members from developing nations said this week.

While rich nations have pledged $789 million, they have only transferred $348 million so far to the Fund for Responding to Loss and Damage (FRLD), which all governments agreed to set up two years ago under the UN climate talks and is now in its start-up phase.

The agency took the unusual step of creating websites debunking the conspiracy theory that chemicals are being sprayed in the sky to control the weather or do other things.

The websites are:

Apparently this conspiracy theory was too bonkers for even the Trump regime.

  • Each fraction of a degree of warming will have a bigger impact than the last on lengthening heat waves, with the most extreme heat waves lengthening the most.
  • Tropical regions will see larger changes than temperate regions, and summer heat waves will lengthen more than winter warm spells.
  • Researchers led by UCLA and the Universidad Adolfo Ibañez in Santiago, Chile, developed an equation that has the flexibility to analyze one region or to gain additional broad insight by analyzing multiple regions as a whole.

Submerged in about 40 meters (44 yards) of water off Scotland’s coast, a turbine has been spinning for more than six years....

The MeyGen tidal energy project off the coast of Scotland has four turbines producing 1.5 megawatts each, enough electricity collectively to power up to 7,000 homes annually.

‍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!
