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.

  • 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.
