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.

It's fair when that's what solar panels are replacing in Australia

Right, but that doesnt mean they're perfect and their flaws shouldnt be discussed, if for no other reason than to ensure it doesnt become a bigger problem in the future.

In addition to the waste problem the article also talks about the world supply of silver being exhausted in ~20 years if solar continues to expand at the expected 5-10x. That sounds like a problem, its probably fixable by shifting to new designs but it needs to be considered and work put into that in order to do so.
