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.

Can we please also mandate landlords to update appliances in rental units if they’re not footing the electric/gas bill? So tired of paying obscene rates for inefficient appliances that I have no control over.

In the case of hot water heaters, they need to replace them every 20-30 years as they corrode, which means that the old one will leak and create expensive water damage if not replaced. They'll buy what's on the market, which means ones that meet the new standards.

Since last year I think there is a law like that in France. For renting an apartment it need to be audited to get an energy performance certificate.

If the performance is too low (low insulation, inefficient heating system ...) then the apartment can't be rented, or if it is rented the judge can allow the renter not to pay rent until the renovations have been done by the landlord to bring the performance to an adequate level.

The minimum performance level is going up every few years until 2030 or something like that.

That sounds like a great policy, hopefully other countries will follow suit!
