Expensive is the wrong word here, most of these calculations are not about money, but energy, they are about doing stupid things like using power from burning coal to collect CO2 emitted from it...at a net waste of energy. It literally emits more CO2 than doing nothing (unless all your energy and factories producing solar panels and wind turbines and cars and infrastructure already run on green energy). It is only good for greenwashing in the near to medium future.

It's a net loss, until you consider: You can pump that CO2 into oil wells to get more oil. That's what most CO2 collection is used for. The collection part is typically stopped when the oil runs out.

It makes much more sense when you realize the point was never to reduce atmospheric CO2.

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.
