Look at this dip during the last week !
Source : ClimateReanalyser.org and NSIDC
Could it be an anomaly with satellite imaging, a random statistical blip, or is something huge just about to start ?

I have no idea what this data is, but I have the gut feeling that we are fucked

[-] Flower@sh.itjust.works 31 points 2 weeks ago

Not completely fucked yet, but being fucked a bit more every year. But fixing things means doing unpopular stuff and not being elected next time.

[-] bedwyr@piefed.ca 11 points 2 weeks ago

That we are not completely fucked yet on climate change has been false for quite a while.

Factoring in our societies, there was never any chance we would change, and feedback loops are already amplifying, that is what will sink us. The permafrost melting will overwhelm the planet's ability to absorb carbon. Yay for anaroebic life!

[-] SaharaMaleikuhm@feddit.org 5 points 2 weeks ago

I honestly believe we are fucked. Even if he would reach net 0 today we would still be fucked.

[-] Eq0@literature.cafe 14 points 2 weeks ago

This has been my gut reaction for the last years of climate related news, lately extending to all other news as well….

[-] edinbruh@feddit.it 13 points 2 weeks ago

I know, Farage winning against Binface has been a shock for me as well

[-] bedwyr@piefed.ca 4 points 2 weeks ago

Binface just showed us a path to reform candidates though. He got solid numbers, 26 percent or something. With a blended joke/real candidate, we could win.

Regardless the US needs this organization of joke candidates that the UK has. I forget what they call it. Loony something.

this is showing the history of area (quantity) of sea covered by ice around Antarctica (South), with each curve being a different year.

In this context, less sea ice is bad news. It is winter there, so the overall ice is still strong. Summer is what matters most (you can see the months on the chart.) Although, leaving winter with less sea ice can make the summer ice situation worse.

[-] cybermass@lemmy.ca 34 points 2 weeks ago

With the super el niño I think this year is supposed to be the warmest on record (so far) so unfortunately I would not be surprised if the lack of sea ice is more concentrated in the northern hemisphere.

[-] BartyDeCanter@piefed.social 25 points 2 weeks ago

I’ve been following sea ice extent for a long time and the number one thing I’ve learned is to not get caught up by any given blip. Sea ice is a complex, slow moving system, so any wobble on the line in a given year is basically meaningless. Look at the year to year and decade to decade trends.

[-] Canigou@jlai.lu 7 points 2 weeks ago

Like you, I've been looking at those graphs almost daily since 2023, but this dip caught my eye.

[-] silver_wings_of_morning@feddit.dk 18 points 2 weeks ago

We are Big F in the uck department

[-] chuckleslord@lemmy.world 11 points 2 weeks ago

As someone who doesn't have a background in climate science, I think it's a really bad idea to look at this and start panicking without context. Just saying

[-] Canigou@jlai.lu 7 points 2 weeks ago* (last edited 2 weeks ago)

Sure, there is more than plenty other reasons to panic 😁
Like some projections of a Blue Ocean Event for 2027...
Or the recent observation of the acceleration of global warning 🥳
But besides panicking, I think a lot of people are really not worried enough...

[-] Fluke@feddit.uk 6 points 2 weeks ago

Man, you're gonna look daft in a few weeks when the ice shelf falls off and the wave drowns half the coastal population centres...

[-] Upgrayedd1776@sh.itjust.works 10 points 2 weeks ago

i got my maga branded panic food cart to hide in, im all good thank you

[-] pageflight@piefed.social 3 points 2 weeks ago

Hopefully. But there are parts of the climate that are delicately balanced and may suddenly cut loose, like potential Gulf stream collapse.

[-] billionsandbillions@piefed.social 3 points 2 weeks ago
[-] chuckleslord@lemmy.world 3 points 2 weeks ago

Yes. Climate change is real. Not, uh, not what I'm saying, but thanks for clarifying.

[-] TheKaul@lemmy.dbzer0.com 10 points 2 weeks ago

Since the powers that be are making no steps to slow this down... we need somebody to invent a Mega Space Air Conditioner that blow exhausts hot air directly into space.

[-] BenLeMan@lemmy.world 11 points 2 weeks ago

That sounds like the kind of idea Elon would have at 3 am while zoinked out of his gourd.

[-] Thorry@feddit.org 9 points 2 weeks ago

Looks like a pretty significant dip yeah. No idea if it's just an unseasonably warm bit that evens out, or if the ice started retreating really early this year. Normally the peak is in September, not August.

[-] frongt@lemmy.zip 3 points 2 weeks ago

There are ups and downs all over the chart. This is well within normal range from what you can see here. OP should never put any money into the stock market on their own.

[-] queermunist@lemmy.ml 8 points 2 weeks ago

Eyeballing it, it looks sharper than anything else before melt season.

But eyeballing charts is also not a good investment strategy.

[-] frongt@lemmy.zip 2 points 2 weeks ago

Eyeballing it, I see similar shapes to the left of the indicated point, in the line at peak of the chart, and in the line at the bottom of the peak.

Climate change is a huge problem, but this tiny section isn't indicative of anything. You can find animations of this chart showing new lines peaking lower almost every year, and that's horrifying.

[-] queermunist@lemmy.ml 3 points 2 weeks ago

I don't see it. I see faster melts during melt season, so from the peak to the valley, but comparing this time of year to melt season isn't really a good investment strategy either.

[-] Shotgun_Alice@lemmy.world 3 points 2 weeks ago

Yeah, I was wondering the same if the peak just happened earlier then what should be normal.

[-] Lemmyoutofhere@lemmy.ca 8 points 2 weeks ago

Super El Niño is really messing everything up.

[-] im_fine_sandy@nord.pub 8 points 2 weeks ago

Firstly, of course we need to be taking immediate action on climate change.

Secondly, i m aware of the trajectory in that sea ice is reducing each year.

That said, my guess is that this is a blip. Ok it might be a sudden tipping point but I think it's more likely that it's a problem with the data.

[-] AeonWorm@lemmy.world 5 points 2 weeks ago* (last edited 2 weeks ago)

SCAR (Scientific Conference of Antarctic Research) 2026 is wrapping up currently. If interested in Antarctic data, I recommend looking at the information coming out of and presented there

[-] Canigou@jlai.lu 2 points 2 weeks ago

Thank you. I will check that out !

[-] frongt@lemmy.zip 5 points 2 weeks ago

I mean there's always something happening, so yes.

[-] BigTurkey@lemmy.dbzer0.com 4 points 2 weeks ago

I swear to Gawd, this better not fuck up my unlimited pasta pass at Olive Garden that starts in 2 weeks.

Go read Ministry for the Future 🫠

[-] Someonelol@lemmy.dbzer0.com 3 points 2 weeks ago* (last edited 2 weeks ago)

Don't know why you're being down voted. It predicts a much more drastic heat dome event compared to what Europe just experienced this year. It even discusses the way the polar ice sheets melting can accelerate if enough water starts accumulating underneath it. It also emphasizes international cooperation to have a chance at curbing the worst of the damage global warming will do.

I’m being downvoted because I pissed off some tankies a while back, so now I usually get a small handful of downvotes on most comments I make, regardless of the topic or relevance (or total lack thereof) to any political stuff. It just makes me laugh tbh, because karma is not a thing on lemmy :P

A blip, just like other temporary abberations in other years.

[-] partofthevoice@lemmy.zip 2 points 2 weeks ago

You’re now the second or third comment I’ve read to mention this. Has anyone actually pointed these blips out though? I’d like to see them.

That's sea ice extent, not measuring the ice sheet (which is the permanent glacier on land).

Also it's well within the historical variability, so probably not a huge flag right now.. Might be worth checking over the next few weeks though. Antarctic sea ice did fall off a cliff over the last decade.. There's also an El Niño building, which is connected to warming I'm the Amundsen Sea, though I don't know how the timing works there.

[-] peopleproblems@lemmy.world 2 points 2 weeks ago

No. This is a sharper momentary dip. Sort of expected with climate change.

If you look at the summer months for 2025, (January and February for the southern hemisphere) you can see ice sheet area declined far more rapidly rapidly than 2026 did.

Rates of change, particularly ones that are of more recent data, can be very misleading. Now if the same rate of change continued through the end of August, then it would definitely be anomalous.

Climate change does not make immediate impacts like this. Climate change makes the trend of the WHOLE line lower, and more volatile. Notice that 2025 and 2026 lines are at the lower end of the graph.

One (ugly) way to understand this chart better would be the area under the curve for a given year. As 2026 isnt over yet, you cant do this reliably beyond the most recent data point.

The "big" thing then would be if the result for each year was successively lower.

[-] humanspiral@lemmy.ca 4 points 2 weeks ago

The “big” thing then would be if the result for each year was successively lower.

graph is from https://nsidc.org/sea-ice-today/sea-ice-tools/charctic-interactive-sea-ice-graph

that grey area shows 10%-90% range. The big thing is that since 2022, ice extents have deviated strongly from that ultra narrow band. Previously year to year and successive moves, were fairly random above/below that range.

[-] peopleproblems@lemmy.world 5 points 2 weeks ago

Yep. I didn't mean to imply something wasn't happening, but that something isn't what OP pointed at, and that something is evidence of climate change.

People need to learn that its a slow decline. It's disastrous, but it looks like worsening wildfires each year. More tornados in Iowa and Minnesota. Lower crop yields. Beaches getting smaller by inches, ocean front property values declining and insurance rates increasing. More intense variations in weather and more difficultly forecasting.

[-] Canigou@jlai.lu 2 points 2 weeks ago

But there are also discussions and predictions about numerous potential tipping points and positive feedback loops.

[-] peopleproblems@lemmy.world 2 points 2 weeks ago

Even those don't mean it's straight for rock bottom.

A tipping point means a point of no return. It will never improve beyond that point. Extent of ice won't show you that. Otherwise when the extent is at its lowest in March, it would never come back.

This measures sea ice around antarctica. It is winter there, and it is very unusual to have a period of over 0C at the time of year (happening right now), but it has a thinner outter perimeter that is vulnerable to breaking away and floating off to warmer water.

There is no relevance to ice sheet stability at this time of year, which is at its strongest.
