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.

Q&A: Why defining the ‘phaseout’ of ‘unabated’ fossil fuels is so important at COP28 (www.carbonbrief.org)

To me this is such a minor thing, that the whole topic, currently widely discussed in media, looks like a distraction from the overall shit show COP28 was.

COP28, with the before leaked documents, that it will be used as platform for the UAE to negotiate new fossil fuel deals behind closed doors. And Sultan Al Jaber saying there is no scientific basis for phasing out fossil fuels to keep global warming under a critical threshold.

To 'phase down' and 'phase out' is the same thing, just with two different time points selected. The event is a fossil fuel reduction and once you phase down long enough, you reach the phase out. It's like a kindergarten group debating a common statement, if later in life they will be teenager or adults. Both is true, one just sooner, the other later. Arguing about the wording detail in a non-binding statement is so silly to me, but there is a whole wave of media publication about it.

The more important CO28 topics from two days ago are gone though.
