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.

We need to have a livable planet, but it's complicated because economists figured out rich folks could get richer by spending future profits that come from more efficient methods extraction from natural systems. It works perfectly so long as our extraction increases exponentially forever... Sure this is something ultimately unsustainable in a closed system, but you see the rich people are in charge and they like how things have been going...

...and in the past nerds have always found a way of extracting more...

...so like I mean, yeah exponential growth is impossible... But surely some nerd shisht will fix it. I heard a rich dude who said he's a nerd say computer super intelligence will be like the Uber nerd and will figure something out...

Which sounds great 'cause all the other smart nerds are saying the exponential growth we've been relying on, based mostly on converting carbon to CO2 is gonna kill us all...

The nerds are all saying to continue exponential growth we need to get energy from the sun and upgrading our electrical infrastructure, creating a ton of new jobs, spurring new industries and bypassing the generation of CO2 we've been relying on...

...But that doesn't sound profitable for the folks getting rich off converting carbon to CO2...

...So it's complicated. /S
