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 did it ! We Terraformed a planet ! Earth, a planet that was exactly as perfect as it gets for us to live on it, we Terraformed it into a suffocating hell.

Technically we deterraformed Earth. Terraforming implies we're making it more earth like when we're doing the opposite.

Can earth become less earth-like? I'd argue that we're changing the comparison standard so that more planets become more earth-like

[–] VieuxQueb@lemmy.ca 10 points 1 week ago

So we are terraforming many planets without even setting foot on them, what an accomplishment!

The main attributes of this planet are skewing away from habitability not towards it.

Technically Earth is always exactly like Earth.

well, getting rid of the majority of humans will make it better for everything else, so there is that.

that we're doing it to ourselves is gob smackingly stupid.

WOO! IN YOUR FACE, CYANOBACTERIA OF 2 BILLION YEARS AGO! WE DID IT IN RECORD TIME!

(2ish BYA cyanobacteria in the ocean produced oxygen, but nothing had yet developed protection from oxidation, thus killing almost everything living)

So that's how they get their religious thing.

Just wait a few years, and soon we'll see a hive colonies everywhere.

Imagine the futur, with underground cities sprawling deep under the surface, people living to mine the rare earth in devotion for the saint GPU !

Change has an effect in both ways, positive and negative, and unfortunately we tend to focus only on the negative.
