Climate - truthful information about climate, related activism and politics.

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.

My hope is NASA and anyone who can check will just tell them it's done. Maybe drop some other satellite, or hide it somehow. It seems like every agency that depends on the data, including the military and amateurs who can track these things from their backyard--EVERYONE wants them to stay up there and would be willing to lie to protect them.

or make some money by selling those satellites to say ESA. They might even be able to provide some jobs.

Maintaining a satellite means expenses. If the funding is cut, the organisation and the people maintaining the satellites and the associated ground infrastructure won't get paid for it. Most of us aren't financially secure enough to do voluntary work as a day job.

Selling them to a different agency would mean that the buyer would also have to allocate resources to maintaining them. Not something that happens at any relevant timescales and it would be away from something else. And transferring the knowledge and skills would be a training operation in its own right.

"Oops we lost control of the satellite. It's still sending all its high-quality data back, but the controls to de-orbit it are locked out. Damn!"
