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.

They are spending 445 million USD on this.

I wonder how many of these flights are to other Midwest cities that could be easily replaced with HSR?

They could even build the rail station into the airport. It is on the edge of the city so there is ample space.

If I were king of the US, I'd connect all of the Major Midwest cities between the Appalachians and Rockies and then run the lines through the SW desert cities and then north up to Spokane and Seattle. Building through the mountains is expensive, so let's not make perfect the enemy of good and go after the most cost effective locations. It would be feasible to run lines from Miami up to Bangor too. Connect it to the Western system through the deep south cities.

I'm from Pittsburgh, PA, and the last time I visited my Mom was telling me that they're going to replace the airport.

She said that they're going to build an entirely new airport just next to where the current Pittsburgh International Airport is. Likely a smaller one, since we have less traffic now than we did when the current one was built. Then they'll just bulldoze the existing airport, I assume.

I asked her how much better spent that money would be to just make a train that takes people from our distant airport into the downtown. It's just nuts.
