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.

Traditional crops are more nourishing for people who eat them and for the soils in which they are grown, according to Mr. Fowler, and they are better at withstanding the wild weather delivered by climate change. The problem, he says, is that they’ve been ignored by plant breeders. His goal, through the new State Department initiative, is to increase the agricultural productivity of the most nutritious and climate-hardy among them.

The initial focus is on a half dozen crops in a half dozen countries Africa.

I definitely recommend looking into some of Dr. Fowlers history, he's such a cool person and his work with Crop Trust was so cool.
