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 we're late. Doesn't mean we shouldn't do it.

For sure, hopefully we can withstand the superstorms long enough to completely alter everyone's quality of life, transition to a circular economy, get all the developing nations off oil and gas, capture the co2 and methane we've been releasing for the past 200, and 10,000 years respectively, and make sure that we don't trigger ww3 in the process! No biggie

Just because we can't do everything doesn't mean we shouldn't do anything. Or worse, like you're doing here, criticize a good thing because it doesn't solve everything.

That kind of doomerism you feel is exactly by design, because the less you feel you can do, the longer the big polluters can keep hoarding wealth.

My guy, humans are a plague on the planet. Unless we all go back to tribal communes living in tune with nature, there's no justification for our existence. Hopefully the next species to develop intelligence learns from our mistake.

Wonder what the new goal will be when we blow past 1.5° lol.

[–] Claidheamh 1 points 1 year ago (1 children)

Doesn't matter, we gotta fight the greedy fucks that got us here for every 0.1°C.

Big difference between 2.0°C and 3.0°C.

We dont seem to be fighting very hard.
