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.

This is also related to the ultimate bullshit about any kind of carbon credits.

The only way it makes sense to sell a carbon credit, at least in a world paradigm (such as it is under Paris) where all nations need to get to zero, is to price those credits backwards from the last ton of CO2 you are going to remove. Because all the tons need to be removed. In the most honest, true, legitimate scenario, selling a credit is taking a loan out against yourself which will HAVE to be paid back eventually.

So the cost of a carbon credit, assuming it actually represents the thing it claims to represent (hint: they don't), should be as expensive as it is per ton of DAC, since DAC is certainly the most expensive way to mitigate emissions.

That means they should be going at something like $500/ton or more in developed nations. Plus the interest on the loan.

In poorer nations, it's possible that those last tons will be cheaper to remove by nature of their lower costs. Maybe that DAC facility built in Indonesia will have lower operational costs than the one you build in Norway. But in that case, selling the credits from Indonesia to Norway makes even LESS sense because now Indonesia is effectively going to have to pay for that last ton to be removed from Norway... where it's WAY more expensive.

If we are to actually believe that carbon credits are what they purport to be, they are usury. They are colonialism. I guess we should be glad they're just regular scams and not that, eh?
