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.

Tools will wear out too and need replacement. Boots, gloves and many articles of clothing will wear out.

If you replace a machine that does the job of 100 people and replace it with 100 people, those people will need to commute to work, they will need to eat, and this will put carbon in the air and/or use electricity. Thermodynamics is a bitch, the energy needed by a group of people to lift something will not be any different from the amount of energy needed for a robot to lift something. Growing food to get that energy and then the person shitting out the waste requiring water treatment plants to process it may not be the most energy efficient way to move heavy objects.

And I've worked on machines that can do calculations to optimize where materials are cut to minimize wastage. A human with a tape measure and a calculator won't be able to achieve this level of material usage optimization. Automation can actually reduce material waste.

A lot of the problems you mention would still be problems even if we went full Butlerian Jihad and eliminated all robots. Bad management? Yeah it's not going to go away when a manger has more employees to manage. Wasteful use of plastic in shipping things? A person can wrap stuff with plastic just as a machine does.

If you don't like automation that's fine. But there's no environmental reasons for being against automation. In fact we need to produce a lot of wind turbines and solar panels as fast as possible. Like a huge number of them. The workforce isn't big enough to produce them all.
