Climate - truthful information about climate, related activism and politics.

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.

This is a major reason why forward thinking public transit investment is so crucial for the PNW.

edit I added some thoughts I see these future climate migrants as an opportunity for the PNW to start building out mass transit infrastructure that can accommodate them, this is an opportunity because the PNW is uniquely positioned in the US to pursue genuine regional mass transit infrastructure and more thoroughly erase the crimes of building this country upon the template of the car than almost anywhere else in the US.

At the end of the day the high rainfall and lushness of the region along with a proximity to a temperature moderating ocean means that we have a responsibility to make room for people who are forced to flee from places that cannot support humans as sustainably, this is just part of what being a good person is about. It will be hard, there will be plenty of growing pains but the PNW can absolutely support a LOT more people and the beauty, natural spaces and identity that people love in the PNW right now doesn't have to be violated in order to accommodate all of those people IF we invest in mass transit and allow density to develop without suffocating the region in suburban sprawl and traffic clogged stroads. It is absolutely possible to accommodate many more people in the PNW while also improving environmental protections and habitat quality, it will be hard and take many many headache inducing balancing processes but it is absolutely possible and if we do it then think of how strong we will be with that many people who love nature as much as we do all living together?

The more interesting question to me isn't whether the PNW is ready for a wave of climate migration, it is whether the rest of the US is ready for that version of the PNW that leaps ahead of the rest of the US in terms of quality of life because it took advantage of this climate migration as an opportunity rather than a burden.
