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.

you're saying the ocean floor is not land?

[–] [email protected] 6 points 2 days ago (1 children)

Yes. It is part of the surface, but it is not "land" by the common definition.

[–] ohwhatfollyisman -4 points 1 day ago (1 children)

what is the definition of "common definition", though? that's a wishy-washy stand, is it not?

the first dictionary definition of the word states that land is the solid part of the surface of the earth, which is contrary to your distinction between "land" and "surface". that's a more solid and substantial position, is it not?

Is this a joke? I genuinely can't imagine you being serious right now.

[–] ohwhatfollyisman 1 points 1 day ago (1 children)

well, i've provided a bonafide source. whereas you've provided only your opinion.

i'm not sure from whence this righteous outrage arises.

i would be happy to understand any issue in my source or any contrary sources that support your opinion that the seabed is definitely not "land".

No, I'm a different guy. It's just really hard to believe you could be serious. That's sad.
