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.

Having lived in both, I rather like being in a dense neighborhood like I am at the moment, but long term, I simply doubt I'll be able to afford it, which I think may be a pretty significant factor for many people. I already live at the extreme northern edge of my city, but if my rent goes up by more than another few hundred dollars a month, I doubt I could afford to find another place in the city that isn't in a terrible neighborhood. NIMBYs make sure that the housing crisis keeps going strong, aided by the byzantine process of community board review for any project that doesn't manage to get killed early on.

Prices are going up in all the similarly dense cities in my region. My options for the future look likely to be sprawl in my home region, with somewhat tolerable conditions despite bad Democratic policies, or sprawl in another state, with worse conditions and worse Republican policies. It's unlikely I could even afford a place in a nice urban region in red states, as their lower cost of living tends to go hand in hand with substantially lower wages. I looked into it at one point, and while apartments in that city were much nicer for maybe 40% of the cost, I would have had to take about a 50% pay cut, while also needing to buy and maintain multiple motor vehicles, as public transit was essentially nonexistent there.

I also prefer dense, urban living, but currently not in that situation. Working in tech in a tech hub blue city in a red state. Relatively lower cost of living, but above average pay. But yes, public transportation is almost non-existent, and you have to deal with the state trying to screw your city over all the time because of politics.
