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.

Here's another good one: The city of Long Beach, California spends close to that much every year to do the same thing to protect mansions built on a sand bar (the Long Beach Peninsula) that are about 50 feet from the water line on a good day. They just keep constantly moving sand from one end of the beach to the other end a couple miles away. That's city money. The article below has some details, but only refers to the city saving $100k to $300k a year by bringing the work in house. The figure I've heard is more like $500k a year. I imagine it's actually higher than that, even. They have dedicated big earth movers, a built facility to store and maintain them, employees dedicated to it, etc. Do the math. This is probably happening all over the country and all over the world.

Let me guess - the beachfront property owners have offshored their wealth and pay less tax than the neighbourhoods without such exorbitant demands?

The upside is that this creates jobs. Yay economy!

Yeah well someday I might get rich, and then I'll want everyone else to pay for me!
