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.

Yes, "chem trails" aren't real. But weather modification absolutely is and you can read government pages detailing the programs since the 60's. We ABSOLUTELY have been putting chemicals in the atmosphere to attempt weather alteration.

Whether this is a good or bad thing is not my point. My point is all these bullshit articles attacking a strawman that doesn't exist. These programs do exist. Conflating them with the chemtrail conspiracy is bullshit tho.

Here's a government website detailing Santa Barbara, California's cloud seeding program that has existed since the 80's

Cloud Seeding (Precipitation Enhancement) | Santa Barbara County, CA - https://www.countyofsb.org/2548/Cloud-Seeding-Precipitation-Enhancement

This is what those laws are targeting, not "every planes condensation trail is actually a secret government device spewing mind control chemicals". Stop calling it "chemtrails" when the very real "weather modification" programs are right there.

Cloud seeding using silver nitrate was developed in the 1980s. It is rarely used as the cost is insane (its silver nitrate).

The patent for using silver iodide was made in 1976 by Bernard Vonnegut and Henry Chessin , based upon work that had been going on since 1946 by Vincent Schaefer and Irving Langmuir.

"Common agents include silver iodide, potassium iodide, and dry ice, with hygroscopic materials like table salt gaining popularity due to their ability to attract moisture."

So you're just wrong. Flat out wrong.
