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.

It’s a shame that the mine isn’t closer to the ocean, otherwise maybe shipping the minerals on cargo ships could have been a more park friendly alternative.

There are rivers and you would only need the roads around the mine and two ports. One inland to move cargo from the truck to the ship and one at the coast, which needs to be built anyway. Obviously the rivers need to be navigable, which is propably not the case.

Hmm. Could the rivers be made navigable without hurting the surrounding ecosystem too much? Or maybe an artificial canal .. but I suppose a new canal has many of the same problems that a new road (or roads) would entail..
