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.

If only there was a cost effective and fuel efficient way to get large amounts of cargo across the US... Oh wait, we figured that out 150 years ago at promontory Utah didn't we? What happened with that? Oh yeah, that panama canal thing was cheaper...

Modernization and electrification of rail is the answer to this problem, and quite a few others. Expand that OG rail run through Utah, and add one through the south end of the Rockies from LA to Atlanta. Full double set of electrified rails to run bidirectional traffic coast to coast in a northern and southern corridor.

We had an answer already, this was a shortcut :)

it can't be more efficient than this: airlines and coal have ruined the canal for everyone. maritime and rail shipping are very efficient.
