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.

I will say that for most trips into Manhattan I'll use public transportation (Train or Subway) just because it's easier and less subject to traffic jams. It's also just nice to read a book while traveling to work. Overall it's a less stressful experience. Almost anything in the outer boroughs I need a car to get to (Parts of Brooklyn might as well be on the moon) However Manhattan is very different then anywhere in San Francisco, whose public transportation I found mind numbingly slow and less frequent.

One place that could use some major improvement is cross-country train travel. My wife and I took a train to Montreal about five years ago and I swore never to do this again. It was painful how slow and shitty that experience was. It really wouldn't take a whole lot to improve this, the bar is that low. I would have paid more money! High speed rail will never get you to the West Coast as fast as an airplane, but if the experience and ease is worth it you can get more customers. However it doesn't seem like Amtrak gives a single good God damn. They might as well be carrying freight.
