The world dedicates a Poland-sized area of land to liquid biofuels. Is there a more efficient way to generate energy?

    Not sure about the calculations here but land can be simultaneously used for solar & agriculture.

      It can, but mostly not for industrial grain production and solar at the same time.

        Pasture for high quality livestock.

          You can do that, but I’d really prefer to avoid ruminants due to the methane that their gut bacteria produce

            We don’t even need to limit ourselves to those two, to be honest. Agrivoltaics is quite flexible and can be used in many different crops and forms (above crops, between crops, etc)

            A surprisingly small amount of seaweed in their diet helps with that, a lot.

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.
