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.

Im not sure what you are talking about, carbon taxes are one of the best ways to mitigate co2 emissions.

If two producers produce the same good, but one of them emits less co2, that one will have higher profit margins.

This is just one of the levers to nudge industries (who, let’s be real, are the main polluters) towards cleaner operations, and as far as I am informed, it’s one of the most effective ways.

So this is good news. It’s good. We have to celebrate that, too, lest we all suffer from doomerism. Can more be done? Yes, there is always more to be done.

But is this a good, important step?

Definitely.

One of the issues with carbon credits is they can be bought and sold. So if my company is more efficient, they can sell their remaining carbon credits to some other company which ends up polluting more.

Carbon credits are basically a fine for polluting. If you can pay the fine, it’s business as usual.

Which makes the environmentaly friendly company more profitable - encouraging others to do the same.

As more and more companies do this, the number of credits can be reduced to increase their price and keep the total emissions on a downward trend.

Yeah a lot of Tesla's revenue is selling carbon credits because their processes are less polluting. They make ungodly amounts of money by doing this.
