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.

Dutch people cycle an average of 2.6 kilometres each per day. If this pattern was replicated worldwide, the study suggests, annual global carbon emissions would drop by 686 million tonnes.

This mammoth figure exceeds the entire carbon footprint of most countries, including the UK, Canada, Saudi Arabia and Australia.

150 years ago, most cities were a bunch of unconnected small towns surrounding a central smaller city. They slowly grew together into the sprawl we have today.

The transcontinental railroad was completed in 1869 and again that’s not even talking about the commuter rail systems that I was mentioning before. You could take a train from New York to Philadelphia in the 1830s. Car companies want you to forget just how connected we used to be.

Uh...you can take a train from New York to Philadelphia today and it leaves like every 20 minutes. Two a day from New York to Cincinnati, but 19 hours. Car would be half that, airplane a fraction. I think it's less conspiracy and more convenience...
