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 was a well written article -- and boy, we're in for a hell of a ride. We need to start shaping cities to withstand larger bursts of precipitation with rain gardens, permeable surfaces, green infrastructure, and enhanced storm water systems. Fortunately, we have many non profits trying to address this with climate corps type jobs, but not as many young folks getting into the trades that we need (construction, plumbing, electric, architecture, engineering, carpentry, metalwork, etc.).

If you're reading this and want to help in these fields, look into getting some basic certifications. Here's a starter link. Also, look up your local environmental organizations and get involved! I've found that if you're not interested in committing to a long term gig, you can find a grant funded position (or be the one who seeks grants on behalf of an organization). Getting involved can look like a lot of different things, and the variety of roles is vast.

I never stopped being fascinated with atmospheric physics. Although I miss being paid to be a researcher, I'm still trying to help on the other end by understanding the economy of green/sustainable industries to bring the two together.
