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.

For biodiversity, for example, if the rate at which species disappear is less than 10 times the average extinction rate over the last 10 million years, that is deemed acceptable.

In reality, however, extinctions are occurring at least 100 times faster than this so-called background rate, and 10 times faster than the planetary boundary limit.

Will the miracle of life actually survive our self-induced extinction?

Life will survive beyond the human generated extinction. Mother natures been through worse, she will shake us off and move on.

Unfortunately, as long as the lights stay on, air conditioning keeps blasting, grocery store stays stocked, and entertainment remains flowing then people won't do anything.

The people who could do something would make them lose the next election, be labeled terrorists, or start get harping on "won't you think of the economy!"

Progress is being made, but drastic measures needed to happen decades ago. The question is now how quickly and badly will things get, and how well we can manage it....

When resources run short and very difficult decisions must be made regarding who around you should suffer so your family can live, remember your conservative neighbors did this.

Conservatives (including neo-liberals) refused to allow normal people to make changes or to pass regulations. They refused to even allow the discussion of change. They killed us and they mocked us as they did it. Decade after decade, conservatives did the bidding of their corporate benefactors, aggressively preventing the rest of us from addressing the problem at all. They should pay with what little resources they may have remaining, if that difficult decision must ever be made.

We like our coal and private jets too much. Let the next generation handle it (if there even is one)

Who's we? I'm not a conservative, a neo-liberal or a corporate exec.
