The Distract me from 2020s P&CE Thread Part Deux

Forza Pangea Ultima!

 

You mean in your yoot? I think you said you made some Ellios pizza recently

 

Well, I've been in SoCal the past 10 yrs so the only time I can get edible grub is when I can get back to the North East.

 

lol. I gotta call "BS" on that one. I mean, I get that continental climates are more extreme but even with a single supercontinent there are still coastal areas. They'll be cooler ocean currents that create foggy coastlines like we have today in San Fran and Lima where mammals would thrive. Not to mention the mammals that live in the sea...

 

A critical thing is that both poles would be continent free thus moderating temperatures since there would be water flow over the coldest part of the planet.

 

Kale sandwiches don't do it for ya?

On that Guy Fietti (or Fieri) show all the gringos from LA go bananas about burritos & enchiladas like they friggin invented them.

 

Haha, by the time that supercontinent formed tens of million years gone by. We humans are near self destruction in the next 50-500 years

 

By then everyone will be really old and will be more concerned about becoming incontinent!

 

What was the weather like in Pangea?

 

That’s not necessarily true.

While it is quite certain that these scientists have made lots of assumptions, I’m going to assume that they know a bunch more about ocean currents and climate patterns than any of us here do. And you need also to consider that the predictions, science, and clickbait headline are all out of sync.

Right now, the ocean is unobstructed in the same latitude around Antartica, and it sets quite an impervious band to surface climate interactions. It’s quite possible that having unimpeded waters in the poles keeps most of the cooler weather in those zones isolated from the super continent. I don’t really know for sure.

Other large shifts in tectonics have resulted in massive volcanism, coupled with significant extinction events. So even if Homo sapiens sapiens (our current classification) remained unchanged over the next 250million years, if we are even fortunate to get there, it’s likely that we would already be completely stressed out, and the super continent might deal a fatal blow. The woolly mammoths were ultimately doomed because of too small a gene pool, caused by shrinking habitat. I doubt whatever comes of our DNA in 250million years will closely resemble our current form today.

Maybe @raza_rebel could chime in?

 

The article was so limited I have no idea what assumptions the scientists made. They could have included the continent free poles in their assumptions.

 

That’s my main point. Most articles like these are almost completely divorced of the actual paper published.

 

"Weather tonight: dark. Turning partly light by morning." [GC]

Oranges are plentiful in the groves so Lord John Marbury was hoping for mimosas.

 

I'll bet you a bag of walnuts as I still have all of them from the past 10 Xmass'.

 

Ok. Mammalian adaptation to heat is stubbornly slow and actually runs into other factors where photosynthesis (food source) breaks down, so evolving our way out of high CO2 levels in the event of mass tectonic shifts along with the sun radiating more will be quite dire. This is not new info.

What they are saying is that 3 out of 4 models predict some form of Pangea-like continent largely within the tropics that operates like a gigantic Australia. We’ll be squished to the East coast, with some places on North and South coasts. The lack of rain in the gigantic arid center will actually reduce CO2 adsorption compared to today’s configuration, despite increased rain events, so the large continent further aids greenhouse effect to spiral. (Rain leads to erosion and carbon capture.)

The 1 other model has Antarctica staying put and the rest of the continents amassing towards the arctic. This still will be a difficult situation, but less dire to mammalian survival.

Point being, regardless of our current CO2 emissions, things are going to get rough. The Sun will turn the Earth into Venus in 1-2billion years no matter what we do. This study says we have a max of 250million years to figure out how to colonize another habitable planet that will outlive this one, or not.

I think it’s ridiculous that we think we’ll survive much more than 100million years at best. Very few complex organisms have managed that.

 

What will they call it? PUFF? (Pangea Ultima Football Federation).

 

No matter what it is named you can still depend on it being corrupt.

 

Turn it into nft's.

 

Hey, I saw the bat signal and thought I would chime in.

I read a page back to make sure what was being asked.

1 - I read the link about the scientists and assumptions. IMHO, and speaking personally, some of these dense topics get lost in translation. Even straightforward issues can be misconstrued. For example, I gave an interview for a St. Maarten newspaper on sea turtles. I was quoted correctly, but the framing leading up to the quote was very out of context. I tried to get the journalist to give an errata, but they moved on and there was little I could do about it.

2 - Re ocean currents/climate - The world's ocean currents are super vital and provide stability to the worldwide temps. Ocean currents are super strong and can push nutrients from nutrient-rich areas (Arctic and Antarctica for example) around the world. To give perspective, the Gulfstream current is as strong as combining the Mississippi, Nile, Amazon, Ganges, and Yangtze and multiplying that by a thousand. Nutrients at the bottom of the ocean get pushed up and end up in areas historically rich in fishing. This will be severely disrupted. The other part is warmer temps are caused by some of these currents. The Gulfstream and keeping parts of Europe warmer, compared to similar latitudes. This can get flipped on its head.

The collapse of one of these conveyor belts will cause a devastating disruption to climate temperatures and a loss of species. A potential collapse of shipping lanes and parts of the food chain would also occur.

3 - I am oversimplifying this as this is not my area of expertise. Salinity/density, global winds, sea ice, and ocean temperature play their part too, But not the only factors. Here is a good starting point (https://oceanexplorer.noaa.gov/facts/facts.html). IIRC there is someone here who is married to an oceanographer. I think they could explain it better. Or maybe someone who studies plate Tectonics (Geologist).

4 - If there is a supercontinent that is formed, who knows how it will shake out and what it will look like? That it will take millions of years and the Red Bulls will still suck. One thing is certain, curbing CO2 emissions needs to happen to get a handle on stabilizing any damage to the environment. IMHO we already passed a lot of red lines WRT climate and species loss. Things will get worse before they get better. Except for NYRB, they will always be the worst.
