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.

No you’re missing my point. The stuff we read and share has a huge effect. If instead of aiming at the very bottom, hoping to pick up enough crumbs to stop the massive tsunami heading for us, we aimed all of our energy at the top, the mood would be very different. It wouldn’t be one of despair because we are reading about the lifestyle changes we need to make, knowing we can do everything possible and there are still millions if not billions of people that don’t have the luxury of making these decisions, not to mention all of the people that could but won’t. Instead, the feeling would be righteous indignation at the true culprits.

In fact, think of all the younger people reading this study, despairing that they don’t have the power or money to make these changes. We’re devastating an entire new generation, poisoning them against the feeling that they could do something positive against climate change. That has a powerful effect. That matters.

The feeling would be very different and we could see some true action that had the hopes of changing our course. Instead, with this kind of shit, it’s a mishmash of anger, despair, bickering over our lifestyle choices (as evidenced here)…it had the exact effect intended. To alleviate the pressure on the companies so they could continue destroying the earth while we sit here feeling guilty about having to drive to work here we live or about our clothing choices, eating habits, using our goddamn a/c in record heat, etc.

We are facing down a massive, gargantuan snake. And there are still some of us talking about taking small bites from the tail up to devour it. Instead of cutting off the head. Do those small bites actually help? On the most minuscule level, yes. But that head is still mowing down on everything and everyone while we argue about how to properly and effectively bite from the tail up. Cut off the fucking head and deal with the rest when the most dangerous part is vanquished.

The ability and willingness among the people to make the necessary changes—not to mention the efficacy of those individual changes on such a massive problem—make this conversation about how to best keep your clean outfits dry on the titanic. Useless. (And as I’ve always had to do in this conversation, qualify my statements by saying that yes, going vegetarian and vegan are great, doing anything with a net positive effect on the world around you is admirable and we should encourage it. But in this context, he framing of the conversation is deadly important. And that’s my entire point.)
