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.

EV sales stats in this article do appear to be electric car sales, even though electric-assist bicycles make up the bulk of electric vehicle sales.

I'd say that they're pointing out that some of the things we are doing are starting to succeed in a meaningful way. That's a big deal, even if we haven't gotten to the point of bending the curve of atmospheric CO2 concentrations.

even if we haven’t gotten to the point of bending the curve of atmospheric CO2 concentrations.

Nothing else matters. This is the bottom line, period, full stop. We've had promises and technological developments and "positive trends" for decades now, and CO2 emissions have just continued going up and up and up. All the while, our governments continue to subsidize fossil fuels to the tune of trillions of dollars, approve record numbers of oil and gas drilling permits on public lands, and don't take any meaningful action to address climate change. I don't want to hear any more of this garbage about how we're "starting to succeed." We're like thirty years behind where we should be.

The permits thing is about the US, where the courts have held that a drilling lease is a property right, so you can't just say no to permits. So Biden cut new leases to the minimum required by law.

acres leased by US bureau of land management by year, showing a huge drop once Biden took office

Getting an end to new drilling permits is going to take more votes and control of the courts than we've had.
