President Donald Trump and right-wing media news outlets are falsely portraying the Intergovernmental Panel on Climate Change’s decision to move away from its most extreme warming scenario as proof that climate science and climate policy failed. In a Truth Social post amplified across right-wing media, Trump claimed the United Nation’s IPCC had admitted its projections were “WRONG! WRONG! WRONG!” and argued that climate activism had been used to scare Americans, justify “horrible Energy Policies,” and fund “bogus research programs.”Right-wing media outlets quickly seized on the technical update as evidence against climate science and climate policy, with Fox News and Fox Business using the same frame to attack climate spending, research funding, and emissions policy. However, the revision reflects the reality that the world has not followed the most extreme fossil fuel expansion pathway, partly because clean energy growth and changing emissions trends altered the outlook.

    The Murdochs, who own the post, have been at the anti-climate science game so long I can’t remember a time in my life when it wasn’t this way.

      The good news is that soon, there will be no more Dirty Digger, and his imbecile offspring will run NewsCorp into the ground eventually.

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.
