Climate - truthful information about climate, related activism and politics.

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.

Biden has taken more action on climate than any president. His pitch? It creates jobs (www.opb.org)

This is an argument I’ve been pitching in the Australian context for some 20 years now - we should have been world leaders in solar technology, to the extent that by now we should have massive solar farms across the North of Australia in order to export clean, green energy up to Papua New Guinea, Indonesia and other near-neighbours. We could have created a whole new industry of both research and advanced manufacturing, and if we’d nationally sequester our resources correctly we could be doing every step of the way - dig out the minerals, refine them, manufacture them into panels, export those panels - all the while generating very low cost energy and exporting it for profit as well! Not to mention so many new jobs!

Even once you take away all of the obvious arguments for climate change action (environmental, ethical, prevention of future disasters etc.) there was always going to be a strong financial incentive in a capitalistic market to move to technology that has the lowest input cost to generate energy, which just so happens to be renewables. It just baffles me that so many politicians crucified themselves on the altar of coal when they could’ve been remembered for ushering in simultaneous economic benefit and environmental benefit, with a long term impact of lowered inflation through cheaper power bills, but that’s what the minerals lobby in this country has managed to achieve. What a disgrace.

Good to see a world leader using the economic arguments in addition to the other more obvious ones.
