Earth continues to break warming records (hexbear.net)

Pictured is a graph of historical global sea-surface temperatures across the year from 1982-2024. Yesterday was about 0.3°C warmer than last year. Well, maybe it will go back down since this is an El Niño year? :>

Average global surface air temperature in February 2024 was 1.77°C warmer than the average February from 1850-1900. So maybe we can retire those 1.5°C warming goals now?

However, the IPCC reports that global temperatures have only risen by 1.1°C. This is because they use decade-long averages. Indeed, it is completely possible that 2025 will be cooler than 2024, but crop failures don't care much for averages. shrug-outta-hecks And if global warming has accelerated, the IPCC's method will be a decade late to realizing it. Not that they can actually do anything about it...

I'm sure there won't be any major consequences to saturating the heat sinking capacity of all of the oceans. Also 2040's here and it called 2030 a nerd, beat it up, and stole its lunch money.

bruh we're going to figure out how to kind of communicate with cetaceans this decade only for them to go extinct due to food web collapse doomjak

"Hey guys. So, first thing, we're really excited to finally break the interspecies communication barrier! Truly a watershed moment for both our kinds. Second thing: and this is really awkward, but we did kind of a major oopsie. Really sorry about that."

First message from us to another species will be explaining the concept of death so that we can subsequently apologize for killing them.

In Disco Elysium, the cryptozoologist talks about an intelligent species of sonic waves of some kind, found to be communicating with distinct regional languages.

The scientists trying to communicate with the sound waves accidentally release a sonic wave that causes them all to pop, and their popping makes the same sound, which spreads until there isn't a sign of any of them left on the planet.

I think about that one story of hers a lot.

It's cool how the narrative on the right about climate change has changed from it being a ~~CHINESE~~ to ~~JEWISH~~ hoax or something to make Donald Trump look bad to now they accept the planet is warming so we need to nuke China to fix it.

No...

BOE summer '24 looking more and more plausible

[–] [email protected] 11 points 8 months ago (2 children)

BOE?

[–] [email protected] 17 points 8 months ago (1 children)

Blue ocean event, no sea ice. Shit starts to get pretty crazy after that.

[–] [email protected] 12 points 8 months ago

Blue Ocean Event - all the summer sea ice disappears

Nothing will fundamentally change, Jack biden-troll

I was promised a cool zone tho.

It will get cold in Europe due to AMOC collapse

I'm in Australia though.

My condolences

obviously this is warmer than usual, but i still have an unrelated stupid question: why isn't ocean temperature basically constant over a year? are they measuring a certain area more than others? seasons shouldn't affect this, so is the orbit doing something weird?

[–] [email protected] 14 points 8 months ago* (last edited 8 months ago) (2 children)

The eccentricity of Earth's orbit is pretty inconsequential. It's something like a 3% difference between the furthest and closest points, the changes in tilt relative to the sun or the kind of surface exposed to the sun make basically all of the difference.

The sun only heats the top layers of the ocean, like a couple hundred feet iirc, and unevenly at that. It would take a very very long time for all the water in the ocean to reach a true equilibrium (if the sun turned off tomorrow) but it doesn't get to because of the day/night cycle, the seasons, wind and the Earth's actual rotation etc. So that produces recurring ocean currents, which are chaotic in nature, thus leading to the ocean temperature to vary (drastically at times).

This newest warming though I think is largely an unintended consequence of the new bunker fuel regulations in 2020 that drastically reduced the amount of Sulfur in it. The sulfur dioxide produced from all those container ships actually has a cooling effect so really the planet was 'already' this warm, we were just countering it somewhat. It also is what is mainly responsible for acid rain so we can't just pump a bunch of it into the atmosphere.

so by enacting certain long-term climate policies, it actually gets warmer short-term? man-made horrors now within my comprehension

Oh yeah that's the fun of dealing with a hypercomplex system. It should help with rewilding efforts but those won't show results for awhile, assuming they're followed through on.

To temper the bleakness a bit, it also means that with the right interventions it would be possible to have similarly drastic positive results.

[–] [email protected] 3 points 8 months ago (1 children)

To add to this we don't really go "around" the sun, if my understanding is correct. We're essentially chasing it as it shoots through space dragging us all in its wake.

[–] [email protected] 3 points 8 months ago

"going around" is a fine enough description. It is true though that the solar system as a whole is orbiting around the galactic core.

[–] [email protected] 6 points 8 months ago

If you look at the scale, the seasonal variations are actually quite small. The ocean temperature was quite stable in a narrow band from 20-20.5C. Was. Water has a high heat capacity and the top few feet of the oceans is a colossal amount of water. I saw last year's rise described as "adding 500 million Hiroshima bombs of heat to the ocean." (Just normal variations I am sure, lol)

[–] [email protected] 5 points 8 months ago (1 children)

Just a guess, but the earth orbits closer to the sun during the northern hemisphere’s summer and farther during the northern hemisphere’s winter.

[–] [email protected] 7 points 8 months ago (1 children)

There's also not the same amount of ocean surface on the northern hemisphere and southern hemisphere, although I think this actually cancels out some of the difference due to Earth's orbit.

ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

[–] [email protected] 5 points 8 months ago

Seems bad

[–] [email protected] 3 points 8 months ago (1 children)

I recall seeing a video about this where they linked it to lower sulphur in container ships, now more sunlight hits the water or something.

Listen here Jack, if I'm elected we're going to convene a commission to study the feasibility of reducing carbon emissions by up to 12% across five key industries by 2075. biden-point
