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.

The Israel-based geoengineering startup has said it expects nations will soon pay it more than a billion dollars a year to launch specially equipped aircraft into the stratosphere. Once they’ve reached the necessary altitude, those planes will disperse particles engineered to reflect away enough sunlight to cool down the planet, purportedly without causing environmental side effects.

The proprietary (and still secret) particles could counteract all the greenhouse gases the world has emitted over the last 150 years, the company stated in a 2023 pitch deck it presented to venture capital firms. In fact, it’s the “only technologically feasible solution” to climate change, the company said.

Mmmm tasty secret particles I can taste them already. They'll pair well with my microplastics

Oh and of course it’s the worlds must trustworthy and socially conscious nation that will geoengineer globally distributed nano particles without any scientific or regulatory oversight…Israel

the "only technologically feasible solution" that allows capitalists to keep doing what they're doing. We already have the technology we need to implement the solutions that will get us 90+% of the way there; countries just have to use it...

It’s almost definitely this method right?

Most likely some proprietary blend of materials that dissipates quickly so they can charge subscription to warding off global warming

[–] silence7@slrpnk.net 6 points 2 days ago

Yes, and proprietary, but without details about what or why.

This is an even more flagrant scam than hydrogen.

[–] Sunsofold@lemmings.world 3 points 2 days ago

The only 'customers' for this are going to be governments. It's just a government program with private legal embezzlers.

Chew on this one, chemtrail conspiracy theorists

Ill need to see the write up on the roll back plan.
