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.

@sonori

I think you're genuinely thinking about solutions, but, your knowledge base needs working on.

"fertilizer and pesticides, which honestly don’t matter climate wise"

They honestly do matter very much!

The "climate" isn't some abstract phenomenon that exists outside of the planet's ecosystems. Insects are fundamental components of an ecosystem. Insecticides kill insects!

Overuse of fertilizer, both organic and synthetic, runs of the land into rivers and oceans (i.e., more pollution)

Nither of which have anywhere near the impact of say, Diesel fuel consumption on global temperatures. Everything you jest mentioned is an effect on the local environment, not the gobal climate, which is to say what we were talking about.
