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.

Remember when the Ivanpah Solar Power Facility accidentally incinerated all those birds because they underestimated the impact mankind could have? Anyway, something just randomly reminded me of that time that in pursuit of cheap energy, humans managed to accidentally burn thousands of creatures to death in a concentrated area.

I'm sure there are no lessons to learn from this.

Mostly that cats and windows kill a lot more birds than solar can even when fully built out.

Oh shoot, I wasn't actually trying to go anti-solar, I was trying to joke about how even when we're trying to be very careful to not cause mass destruction in an isolated area, we still manage to murder thousands of birds each year as whoopsies. Imagine how much more damage we're doing when we're not paying attention and are using explosions that fart out toxins and solar oven lining instead of highly focused sunlight.

The major point I'm making is that it was AFTER we incinerated and blinded a fuck-ton of birds that we slowly started fixing the problem over the course of years and have determined that the thousands we're still killing accidentally is acceptable collateral in the name of energy production. Well, now we're finally getting people to notice, report, and possibly address the issue because there's an undeniable correlation between how we're producing energy and mass bird die-offs. We have barely begun to refocus the metaphorical mirror and are nowhere near the levels that will be considered acceptable collateral damage. That acceptable level of collateral damage is going to be devastating... But at least a handful of people will have had the opportunity to be unfathomably rich for a little while.
