If we want to use Direct Air Captur to limit overall warming to 1.5°C, while emitting enough to reach 2.5°C, DAC would need to use something like 30% of all electricity consumed over the next 80 years

      How about total cost of all goods and services. Pretty standard GDP way.

        So break all the windows in your neighborhood and the GDP goes up?

        Sounds like a good way to stimulate significant parts of the economy, infrastructure-like projects generally do

          Its a lot cheaper and broader to avoid burning fossil fuels in the first place.

            Is it actually cheaper? If so should be easy to subsidise the greener options

              Yes. By a lot. In almost all applications.

              The problem is that the fossil fuels industry holds a lot of political power and uses it to block shifting off fossil fuels

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.
