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.

So far, scientists have found that we’re trending toward the high end of those predictions. ... “Presently, sea level is tracking in the intermediate-high to high, the two fastest,” said Randall Parkinson, a coastal geologist with Florida International University. “The other three scenarios, you might not even think about because we’re already rising faster than that.”

Gonna be real funny when that 6 ft by 2100 drops to 2050 and most of Florida become the climate migrants nobody wants.

My in-laws just bought a house near the coast in Southeast Florida. I don't know what they're thinking. Maybe they're too old and stuck in their ways to believe that this will actually impact them? I don't know, but I imagine it won't be long before they can't insure that house anymore.

it’s not an obstacle, it’s an opportunity! – Florida has a long and prestigious tradition of selling waterfront property

Somehow I feel that capitalism won’t solve the problems that capitalism created.

The same kind of flooding that hit Brazil I expect to hit south Florida within the next year.

Florida does have a rigorous pumping systems due to hurricanes. So we will be able to pump the extra water out.... eventually. That being said, flooding will still persist for days at a time.

Though I am sure our elected officials won't just pretend that climate change doesn't exist..... and will put effort into upgrading that pumping infrastructure....

is the pumping system up to the same standards as Texas’ electric grid?

Not funny! 100's of thousands of people are currently in the dark because a thunderstorm came through 4 days ago!. JK. Maybe if enough people make fun of the joke of an electrical grid Texas has, it'll be improved.

Individual storms are random enough that I'm very hesitant to make that kind of short-term statement.

RIP to any freshwater animals living in florida.

Takeaways:

  1. buy land in ATL.
  2. Political implications interesting. Since the poors will be the Floridians withiut options, it makes sense they'd go to GA...normally poors would be bluish voters but in FL, fuckssake who knows. Rich FL will just fly back to their homes in AZ, TX, NY, etc.
