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.

Building codes are holding back low-carbon concrete. A new study shows why. (www.anthropocenemagazine.org)

Building standards treat all concrete the same, hindering the use of greener concrete, but climate conditions play a much bigger role in determining a structure’s durability

The department that tests products and updates the code is probably underfunded

The study is for Europe, but in the US, the construction industry writes a model code and localities mostly just adopt it with fairly limited local changes

Underfunding of regulatory departments and rubber-stamping is also common in Europe, it was a major factor in the Grenfell fire
