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.

Indoor farms are remaking the produce market — at a cost to the planet (wapo.st)

Energy use in the industry varies widely depending on greenhouse size and what crops are being grown. A study of 12 indoor farms by the nonprofit Resource Innovation Institute found that five of them used as much energy, per square foot, as a hospital. One vertical farm, an outlier, was guzzling as much energy as a data center.

I agree that it is worth looking at this in a more distinguished way, but carbon budgets for large farms rarely take into account the carbon emissions produced by organic soil loss, besides the vast negative effects that has otherwise. Indoor farms on the other hand can be pretty carbon neutral after their initial construction, assuming that the electricity they use comes from renewable energy sources.
