Re: Changes in Atlantic currents
More about:
“Ocean current system seems to be approaching a tipping point” ~ by University of Copenhagen
➥ https://phys.org/news/2021-08-ocean-...proaching.html
And:
“Study pinpoints key causes of ocean circulation change” ~ by University of Exeter
➥ https://phys.org/news/2021-06-key-oc...rculation.html
The study [abstract only]:
“Observation-based early-warning signals for a collapse of the Atlantic Meridional Overturning Circulation” ~ by Niklas Boers
“The Atlantic Meridional Overturning Circulation (AMOC), a major ocean current system transporting warm surface waters toward the northern Atlantic, has been suggested to exhibit two distinct modes of operation. A collapse from the currently attained strong to the weak mode would have severe impacts on the global climate system and further multi-stable Earth system components. Observations and recently suggested fingerprints of AMOC variability indicate a gradual weakening during the last decades, but estimates of the critical transition point remain uncertain. Here, a robust and general early-warning indicator for forthcoming critical transitions is introduced. Significant early-warning signals are found in eight independent AMOC indices, based on observational sea-surface temperature and salinity data from across the Atlantic Ocean basin. These results reveal spatially consistent empirical evidence that, in the course of the last century, the AMOC may have evolved from relatively stable conditions to a point close to a critical transition...”

Re: Changes in Atlantic currents
Oh dear, another one and we're still bogged down in the reef health issue.

Try not complaining so much. No one is forcing you to either read or respond to this thread.

Nah, not complaining, observing. We all know where this one is going to go.

Re: Changes in Atlantic currents
It's pretty foolish to reject that climate change is happening. I suppose if a person buries their head deep enough...

Re: Changes in Atlantic currents
Emma, the teacher, is reading her class the story of Chicken Little. Emma gets to the part where Chicken Little tries to warn the farmer. "So Chicken Little went over to the farmer and said, 'The sky is falling, the sky is falling."
Emma then asks her class, "What do you think the farmer then said?"
Little Moshe raises his hand.
"I think he said,
'I can't believe it! A talking chicken!"

As I like sitting on a boat in warm climates, please remind me again what the problem was? Raising sea levels? Warmer weather?
Plastic pollution of the ocean on the other hand is a real concern, which actually would deserve to be tackled and could be solved in a measurable way without fancy-shmancy hockey-stick charts.

Because there are no regional climates on the big blue marble. It is all interconnected and what effects one area effects the entire world. But then, I am certain you already knew that.
Food for thought, the US Department of Defense is not what anyone would call a "liberal" organization and yet they list climate change as the single biggest threat to US security in the next 10 to 20 years.
I know, reality is not always pleasant.
