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.

I get a lot of engineers at my job who don't understand the concept but they react to it in extreme ways. Like when we talk about plasma, there would always be someone bringing up how you can't use certain materials near plasma or near heat or in vacuum. Yet some how the machines we make work and you even have on your hands a little TV screen powered by all sort of circuitry that shouldn't exist because x or y factor that some guy always thought wouldn't work because they were not in the team that actually made the thing work. But do keep telling us how plug-in hybrids don't work. I only spent a decade in that industry actually developing motors, gear drives battery packs etc, and just so that some guy over here who maybe had one or drove one last week and has some options now controls the conversation. To me. Seeing is believing. I drive a little hybrid, I watch the gauge and it tells me, hey you got 57 mpg! Yey! But what I believe is that I do maybe 14 trips a year to go get gas and it's way cheaper than when we fill up the van. As a user of my Toyota hybrid, that's the bottom line regardless of my engineering degree and years of experience in the matter.
