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.

It's almost like Republicans want oil to be ridiculously expensive and to force us all to buy it.

Cycle lanes, electric cars and other interventions have helped 19 global cities slash levels of pollutants by more than 20%

Notice how the main approach was to avoid burning stuff. That's a key step which both reduces the amount of warming we'll get, and avoids significant local pollution.

President Donald Trump is preparing to invoke Cold War-era powers to clear the way for renewed oil production off the southern California coast, a long-shot bid to help ease the global crude supply crunch spurred by his war with Iran.

The Oil Sands Alliance — rebranded from the Pathways Alliance — has a history of misleading the public about the fossil fuel industry's support for climate action, all the while pushing to expand production.

Brian Joondeph, a Colorado-based ophthalmologist and political commentator, has not published peer-reviewed research on air pollution science.

...

Dr. Joondeph said he was nominated to the panel by the CO2 Coalition, a nonprofit group that claims that planet-warming carbon dioxide is beneficial to humans, contrary to the scientific consensus.

From here

SEC. 15. (a) (1) Section 302 of the Clean Air Act is amended by striking out subsection (g) and inserting in lieu thereof the following:

" (g) The term 'air pollutant' means an air pollution agent or combination of such agents.

" ( h ) All language referring to effects on welfare includes, but is not limited to, effects on soils, water, crops, vegetation, manmade materials, animals, wildlife, weather, visibility, and climate, damage to and deterioration of property, and hazards to transportation, as well as effects on economic values and on personal comfort and well-being."

(2) Section 103(c) of the Clean Air Act is amended by striking out "air pollution agents (or combinations of agents)" and inserting in lieu thereof "air pollutants"

Relevant because a semi-prominent publication published a false statement about this today.

  • As the EU’s Deforestation Regulation (EUDR) nears implementation this year, furniture giant IKEA may need stronger traceability systems to prove its timber isn’t linked to post-2020 deforestation.
  • Although nearly all IKEA wood is FSC-certified or recycled, past investigations show this voluntary scheme can miss illegal or unsustainable logging.
  • The EUDR requires geolocation data and stricter due diligence than existing certifications or regulations, but repeated delays and possible rule changes have created uncertainty for companies like IKEA preparing to comply.
  • Industry watchdogs say high-profile companies like IKEA can “do more” to champion the landmark regulation and implement leading wood traceability systems, rather than relying solely on existing — voluntary— certification schemes.
