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.

“I have a foreboding of an America in my children’s or grandchildren’s time—when the United States is a service and information economy; when nearly all the key manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when, clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what’s true, we slide, almost without noticing, back into superstition and darkness.”

“And when the dumbing down of America is most evident in the slow decay of substantive content in the enormously influential media, the 30-second sound bites now down to 10 seconds or less, lowest-common-denominator programming, credulous presentations on pseudoscience and superstition, but especially a kind of celebration of ignorance.”

Hey kids, never let any Millennial tell you we didn't know.

I autotuned Carl Sagan's Pale Blue Dot speech and I put it on my youtube, then I deleted it later because I thought it sucked. The music was good, but the software I used to make it was cheap, so it didn't sound professional. I've looked for it, and it seems to be gone forever, so I guess I'll just have to redo it

How about a link to something similar? Symphony of Science is basically the same thing only it isn't just Sagan. https://youtube.com/playlist?list=PLFC4EE4355ADEBDB1
