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.

These trains could carry giant batteries across Colorado and deliver clean energy to Denver

SunTrain wants to use the existing freight rail system to transport clean energy from wind farms and solar arrays to the grid.

This is probably much more efficient the closer you are to the equator. Not saying it's a bad idea, but we'd have to make sure it's economically viable before we dove in.

It's an interesting idea though. Kinda reminiscent of "It's hard to beat the bandwidth of a truck full hard drives barrelling down the i95".

This is trying to quickly help with a lack of electricity transnmission. Canada as a country mainly runs of hydro However some provinces ike Alberta have a lot of coal electricity. So being able to transport relativly clean hydro power to replace coal just makes sense.
