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.

For cost and emissions, I think the nascent field hasn't matured correctly.

The insect farms I see are farms out in rural areas where they truck in feed and truck out protein. A better model would be urban light industrial, where a city can divert grocery store spoiled vegetables to the urban insect farm. Just a few collection points and short distance for big payloads of human food grade waste. Perfect for hungry insects. Easy for an EV truck to do.

Passive house style building with photovoltaics reduces emissions to nearly nil. Insects grown can be processed on site into powders, then further onto food processors with minimal transportation because the entire supply chain is local, and its a waste stream being converted to productive use.

The rural areas are where you run-into the least NIMBY-ism, full-stop. Insect Protein still has a rep in the food and high-brow agriculture world akin to Nuclear Energy or Strip-Mining.

Oh, well if there is nimbyism at play we should just all lie down and accept our fate.

... or just build the stuff where it can be built? Rural≠"Useful for Agriculture", it really doesn't.
