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 something. I'd like to see something more comprehensive, like also public transit for the islands and dramatically higher gas/car costs. Maui has like two roads, it can't be that hard to add a train and kill all the tourist parking. Blows my mind that this isn't a thing already.

Suing oil companies is great too but why not actually eliminate oil from the state entirely and make tourists pay for it? Hell I'd price out carbon for their flights and find a way to charge for that too, and spend the money on decarbonizing the entire state and climate adaptation.

That all being said, this is a start so let's build from here and force the wealthiest tourists to be carbon neutral and take care of these places.
