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.

Australian red meat industry says it doesn’t need to meet its self-imposed net zero target (www.theguardian.com)

Prof Mark Howden, the director of the Australian National University Institute for Climate, Energy and Disaster Solutions, said the sector’s net zero target is “effectively not possible”.

“It’s pretty well embedded in the public consciousness that red meat is high profile in terms of greenhouse gas emissions per serve,” Howden said.

“I suspect the industry saw this as a fundamental threat to their future … A few years ago everybody was kind of jumping on the net zero bandwagon without actually thinking through what it actually meant,” he said.

The CSIRO found the industry would fall short of meeting its net zero target, and instead recommended the adoption of a “climate-neutral” target that would require a reduction of methane emissions rather their complete elimination.
