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.

The carbon dividend makes the policy overall progressive, like a mini-UBI. It seems we agree that helping the poorest people is a good thing, and they will benefit the most.

The carbon tax should not be an exclusive policy. Canada estimates its tax will account for 1/3rd of its emissions reductions by 2030. That's a nice big chunk for one policy, but plainly insufficient on its own. Absolutely fund renewable infrastructure (including subsidies), public transport, walkable/bikeable housing, etc. Set hard limits / bans where appropriate (banning all emissions is not remotely feasible). A carbon tax is highly complementary to these.

Politics is messy. In Canada the Conservative Party (remind me -- are they for or against fighting climate change?) opposes the carbon tax, and associates it with Labor, so they have a ton of propaganda against it. Half of Canadians don't even realize they are getting a huge rebate back, let alone that it's more than they are paying in taxes (Abacus Data). That's why it's important to get people to understand how a carbon tax actually works.
