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.

There's a difference between the earth's land and the earth's surface.

[–] ohwhatfollyisman@lemmy.world -2 points 1 month ago (1 children)

you're saying the ocean floor is not land?

[–] cravl@slrpnk.net 6 points 1 month ago (1 children)

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

[–] ohwhatfollyisman@lemmy.world -4 points 1 month ago (2 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@lemmy.world 1 points 1 month 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".

[–] FooBarrington@lemmy.world 1 points 4 weeks ago

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

If it helps, I don't think any worse of you because you got the definition of a word confused, even if it hasn't changed since it was inherited from Germanic prior to the 12th century. We could probs still be friends barring any major personality conflicts. 🙃

Cambridge Dictionary:

the surface of the earth that is not covered by water

Collins Dictionary:

Land is the part of the world that consists of ground, rather than sea or air.

Oxford Learner's Dictionary:

the surface of the earth that is not sea

Oxford English Dictionary:

The solid portion of the earth's surface, as opposed to sea, water

And finally, the one you quoted:

Merriam-Webster Dictionary:

a. the solid part of the surface of the earth

b. ground or soil of a specified situation, nature, or quality (dry land)
