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.

In-person conversations and hands-on experiences are what ultimately shifted my worldview. During my undergraduate degree as an anthropology major and first-generation student, I remember holding an ancient hominin skull in my hands while inspecting scientific literature that rebuked my childhood teaching that evolution wasn’t real. In classrooms, I could debate and discuss lessons with students. In lecture halls, I had access to the words of professors and scientists with decades of experience and anecdotes. I began to see that there are many ways of existing in the world

I believed <situation/thing> was <fake/bad> until it impacted me personally.

It's not even that; it's just that he talked to people whom he saw as peers who were able to tell him that things weren't how he thought. And he did it in a context where he had distanced himself physically from a community of people who were deniers.

Right, he didn't believe it until it came from his ingroup. Which is the same thing with more steps.

None of the words changed... only who was saying them.

I promise, I'd be kind and polite in a conversation with the author, and it's important that we welcome latecomers to our side. Hugs for everyone who comes aboard the ark!

But anyone who's been undecided on climate change until 2025 has also been very stupid until 2025.

Every fucking time.

Conservatives do not understand reality except in terms of interpersonal trust.

I mean go north and listen to the people there. Permafrost melting grass growing where there has never been any. Not sure why Alaskans can't see it or is Alaska more.mild then Nunavut and the NWT?
