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 proves that solar can be easy and widely adopted (www.volts.wtf)

Australia has high rates of adoption for rooftop solar. The interconnection is easy and permitting happens over night. And best of all, none of the fears associated with wide spread solar have materialized into real world problems.

I don't know how it works in Australia, but a plus to subsidizing solar installation on roofs is that the home owner still has to co-invest for a considerable part, so you kinda get a leveraged build out, as opposed to the government directly building installations. But the balance between private and public good should be weighed carefully all the same.

Im very pro rooftop for this reason. The most efficient place to generate electricity is where it will be used. The more transmission you need, the higher the cost. If the majority of energy is generated at the point of use, or close to it, transmission lines are only needed to balance out the margins
