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.

Australia joins the group of these 24 countries, and they didn't lobby against phasing out fossil fuels - unlike Russia, China, India, the U.S.. Saudi Arabia, and some other oil producing countries.

Australia's reliance on coal-fired power drops to record low in early 2025, the country pledged to end coal consumption by 2038 or earlier (no, that may be not enough, too, but China, India, Russia & Co are not even close to this, and they do nothing that it gets better).

Yeah, coal is decreasing as a share of our domestic usage, but we are still one of the world's biggest coal exporters.
