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.

With all of the horrible stuff happening in the world, I wanted to share something positive. This is our first year with a CSA, and I could not be happier. When we first signed up, they required us to come visit their farm. Our farmers are just a couple and their kids. They grow the majority of their own food, and also feed the local community. The food we get is the tastiest, freshest produce we could ever find (other than growing stuff ourselves). I saw someone posted a fruit cup the other day, and it said something along the lines of being produced on one side of the planet, then shipped half way across the globe to be packaged, then back to be sold in US. Then I thought about our farmers. Our food travels 30 minutes to the farmers' market. That's it. How many emissions would that save if everyone did that? In case any of you are interested, and are in US, you can find your local CSA here: https://www.localharvest.org/csa/
