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.

Parasol = sulfur dioxide acid rain producing dirty bunker fuel

Lower sulfur fuel was finalized in 2020, but started in 2000. Lower cloud formation was instant. Rather than glorifying the acid rain parasol, a more likely progression of global warming is as a step function of El-nino events. Ocean warmth increases and stabilized temperatures to a new plateau each time.

Climate deniers take heed - another warning has been sent to all Time has run out on the grace period of fossil fuel useage - the piper will be demanding pay soon

And they will just call people who care "doomers", and go on with their business as usual until we all burn.

They will declare it's the end times and their God will be back soon.

"God is destroying us because we treated trans people like humans."

I wish I was exaggerating.

The lake, the sea: the tireless gloves...
Where nature's hand.
Still holds her sceptre far above...
Her bastard, man.
The shore where centuries of sand...
Through waves have raced.
Invites a swim, but think where man...
Deposits waste.

It's probable that cutting sulfur emissions of marine fuels in the last years have reduced earths reflectivity, explaining the observed change in energy balance and the speeding up of the heating process -> "lost the Parasol"

The short version is as the title suggests, warming accelerating pretty dramatically, and based on recent studies we're fast approaching a hump that if we cross over, would likely result in a runaway situation that could not be fixed on human timescales. It's getting so bad even business analysis of the issue is suggesting drastic changes, such as not waiting for market forces to transition away from fossil fuels, but instead suggest governments globally super-charge the build-out of renewable energy sources.

What isn't said in the video: Basically unless we get off capitalism very soon (especially combined with the knowledge from a different study that suggests the atmosphere may become toxic to humans in the later half of this century), we're potentially looking at mass extinction much sooner than expected if we continue with our current way of life.

We can already expect USA to say "NOOOOOOOO, MAH PROFEEEETS!!! YOU'RE HURTING MAH PROFEEEEEEETS!!!"

Pretty much all industrialists, tech-bros, and billionaires will be screeching that the world over, as there's virtually no place left that isn't chock full of multinational corporations. I guess they turned out to be the final boss for humanity.

I'm rooting for us pulling through, but it'll take global grassroots organizing, militant unions, and a shit ton of mutual aid to prevent them from literally killing us all due to their mindless greed and lust for power.

The sun will burn a hole right through...
Your parasols.
The clouds so sick they've split in two...
From aerosols.
The air will fill your lungs with fists...
For ev'ry breath.
'Til future days when life exists...
To mirror death.

Lmfao, is that where the F thing comes for? I've been trying to figure that out for years hahaha

yup. this terrible call of duty story mode

Is there a link to something that isn't a video?

[–] Tiresia@slrpnk.net 5 points 6 hours ago

https://actuaries.org.uk/media/isvotyer/parasol-lost.pdf

The first link in the description appears to be what the "parasol" in the title comes from.

It seems to be a partially AI-generated report by the University of Exeter, with the cover image being the most obvious marker. The "parasol" in the title doesn't seem to represent anything specific, so maybe that was AI-generated too, or maybe it was artisan hand-crafted clickbait.

The sources he uses are in the video description, if you'd prefer to read them.

[–] MNByChoice@midwest.social 6 points 21 hours ago (2 children)

All but one of the sources are from the same website. An internet search for the earth's parasol finds lots of proposed projects.

Does this Youtuber discuss real things? Do they have a good reputation?

About me, to contextualize my opinion (skippable): I'd rate myself as a moderate to highly informed consumer of new media. I'm quite critical of channels and judge their factual value and practices, and I have a pretty good grasp on who I watch primarily for entertainment (Vaush, LTT,...) and who I watch primarily for information and meaningful analysis (Belle of the Ranch, Gamers Nexus,...). I try not to let my opinion be swayed by online sentiment either; e.g. I'll heavily criticize channels for factual errors and what I can only call 'journalistic negligence' even when most people don't seem to have an issue with them (e.g. Matt Ferrell's Undecided)

I've watched Just Have A Think for a few years now and his videos tend to be pretty solid and draw from a good variety of sources. He does an okay job of separating his opinions form the facts and not sounding too authoritative when he's not quoting an authority. This is also helped by his style being informal and infotainment rather than news-like. The titles and thumbnails can be a little clickbaity at times but the substance is there. Many of his videos, including this one, just consist of him presenting and intellectualizing papers or reports from reputable or authoritative sources.

Overall, I'd say it's a channel worth listening to.

[–] ProdigalFrog@slrpnk.net 6 points 21 hours ago

I've been following them for a while. They have a solid reputation from what I know, and I think they do a good job of explaining recent climate studies in layman's terms.

[–] jmill@lemmy.zip 5 points 23 hours ago

I haven't watched this yet, but I'm familiar with his channel. He typically pulls in info from a few different sources (often studies, which he does cite) and talks about them. Pretty worthwhile.
