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 these ideas involved profit, I would have some hope they could be adequately tested or even deployed on a test scale. But between a lack of a clear profit path and a long history of conservative obstructionism globally, I think it's a fair prediction that these treatments will not be attempted on a meaningful scale.

When things start getting bad enough that people in power at the moment are deeply affected, we'll see an incentive to focus on immediate solutions that actually work. That's when the window for drastic measures opens. For now, it's just a waiting game. Vote for the least worst candidate, donate if you can, and do your best to explain the situation without freaking people out so much they won't listen. Hopefully renewable energy wins that race, but as long as it hits the rich before we hit collapse, there's a chance for drastic measures to occur and work.

Our economy currently operates in terms of quarterly gains. I don’t expect that to change. The system will continue to support short term mitigation over long term improvement until it literally collapses under its own weight. While regulation will hopefully continue to stifle the brunt of climate change, corporations will continue to do everything in their financial and other power to push forward their short term profits, at the expense of everything else.

I agree that voting and donating is the best course of action, but the snowball is already rolling down the hill, and those who have the power to stop it would much rather just slow it down if it means a bigger payout.

Those in power that are deeply affected are already seeking ways out. Mars colonization and private space travel is an important human goal, but as it is being funded now it’s a way for those in power to ensure that they, and their children, and those who can pay for it, don’t need to live here once everything goes tits up. Billionaires have contingencies as they keep pumping profit out of the earth. For us, like you said, it’s a waiting game.

The climate deniers profiting off this know this, but they think people are too stupid to understand what will happen.
