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.

This is an oversimplification. It is true that organic farmers are permitted to use certain chemicals on their crops, but the allowed substances are very different in terms of ecological impact compared to conventional chemical treatments (conventional chemicals and their breakdown products generally persist in the environment much longer).

Organic farmers are also required to try to manage pests without chemicals first, steering the organic industry towards "integrated pest management" where very small amounts of pesticides are used in a highly targeted manner.

I don't see anything backing up your alternative insect control claims, but it really is just a different batch of pesticides on wide use.

Here is an excerpt from another source summarizing the requirement for integrated pest management:

"These plans address three levels of pest management. Level A is based on the expectation that a well-designed and healthy organic system will naturally have fewer pest problems. It focuses on pest and disease outbreak prevention practices such as cover crops, crop rotation and providing habitat for ladybugs and other beneficial insects.

If Level A practices are not sufficient, Level B focuses on the introduction of insect predators and parasites, mulching, grazing, mowing, solarization and other mechanical and physical practices.

If additional pest management is needed, Level C includes the use of natural and synthetic pesticides on the National List."

Also, the list you have linked is so so much less bad than the list of allowed chemicals for conventional farmers, which I can't even find online... Best way I have found to view it is here: https://ordspub.epa.gov/ords/pesticides/f?p=CHEMICALSEARCH%3A46::::

Bottom line is that conventional pesticide use is much less transparent and less tightly regulated.
