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.

It's so silly. Even if you don't understand the science of climate change (which isn't that fucking hard to understand) you can definitely understand this;

  • Solar PV + Battery: ~2.0–2.7 USD/W (2.4~ $/kW)
  • Solar PV standalone: ~1.33–2.74 USD/W
  • Wind (onshore): ~1.46–5.9 USD/W
  • Hydro: ~3.0–5.9 USD/W
  • Coal: ~3.1–5.5 USD/W
  • Natural Gas (combined cycle): ~1.06–1.2 USD/W
  • Oil/peakers (simple turbines): ~0.8–2.6 USD/W
  • Nuclear: ~6.7–8.0 USD/W

Even with batteries solar has the greatest fricken ROI in this list at the cheapest cost.

Fossil fuels are finite. After you pay back your solar panel capex your opex is barely anything and for the next 20-30 you have free fucking energy.

Jeebus, even if you don't give a shit about the environment picking anything but renewables is like the dumbest decision you can use your money on.

That's the weirdest thing about it. "Green" can be, and is profitable. Why pass up the opportunity to be the front-runners in what could be the new age of wealth?

with late stage capitalism, you get better ROI sabotaging the competition and just generally smashing shit around you. america is filled to the brim with disaster capitalists and republicans being in power is their green-light to finally take their masks off

I like you, but I don't like your words because they make sense. I do wonder sometimes if it is actually late stage, or just 1929 stock market crash repeating with some variations. Or all the market crashes of the late 1800s. A lot of similarities, going up to 1929 people were doing BNPL on RCA radios. Today it's groceries and cell phones.

I will say one thing though, late stage capitalism sounds dark and scary because "the way of life" is going away, which always means we poors suffer and die. The other angle, is maybe something better will finally fight its way to the surface. Not what those billionaire idiots want though. Hopefully it will be as damaging to them now as it was back in the 20th century when they were somewhat put in their place for a century. Capitalism only ever worked if the evil was regularly regulated, as greed is inherent in the design.

Next Stargate reboot ep, SG-1 visits a planet where they have the centennial saving of freedom by vanquishing the evil rich, as told over a few centuries, and only SG-1 can save them this time.

Apparently conservatives are not only shit businessmen but their also dumb fucks who will believe anything you tell em as long as you throw in some racist platitudes

Conservative governments in Western democracies have always tanked the economy. Always.

For us. Profits go up in the short term for them and their crooked buddies. But unfortunately, you are right.
