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.

Animated by the “move fast and break things” credo that permeates Silicon Valley, the founders of Make Sunsets have no such concerns. They are selling “cooling credits” to customers who want to offset their personal carbon emissions. And a few times each month, after selling enough credits, they head for the hills and release balloons full of sulfur dioxide into the California sky.

“This is the one tool realistically that can cool Earth in our lifetime,” said Mr. Iseman. “Every day we’re not doing this leads to needless harm.”

Sikina Jinnah, a professor of environmental studies at the University of California Santa Cruz who has studied geoengineering, is also concerned about harm. “They are a couple of tech bros who have no expertise in doing what they’re claiming to do,” she said. “They’re not scientists and they’re making claims about cooling credits that nobody has validated.”

Yeah....Gotta admit I didn't have a lot of confidence in the idea when I first started reading the article. Then I read this part and my confidence went from low to zero.

Silicon Valley, where scams go to get funded.

Yeah, this is a giant scam. The whole "we're stealth" and "we look just like a regular RV" are key giveaways. If what they were doing was 100% legal and above board, they wouldn't be doing it this way.
