Three years left to limit warming to 1.5C, leading scientists warn

[westwall]

The sun is remarkably constant for it’s class.

Explain D-O events using the sun.

Sure, the Sun most likely has hot phases, to go along with its cool phases. The periodicity of the D-O events links up with one of those solar cycles.

Not the Halstatt, one of the intermediaries. Its cycle is between 1200 and 1500 years IIRC.

Correct, using the WIND, not the ocean currents. Surface currents are short lived. They last only so long as some other force doesn't interfere.

Such as another wind, from another direction.

Did you read the Wikipedia article? ... that describes prevailing winds ... average over climatic time periods ... the forces that redirect these ocean currents are the continental masses ... forming the clockwise gyres in all the major ocean basins (except the Arctic Ocean) ... most any map will show this ...

See how these currents are coincident with the prevailing Trade Winds and Westerlies?

"Surface currents in the ocean are driven by global wind systems that are fueled by energy from the Sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents." --- NOAA's "Ocean Explorer" -- n.d.

No one believes D-O events are related to solar activity.

No one believes D-O events are related to solar activity.

So what? No one knows what causes them either. It's all theoretical.

I don't read wiki. It's not a reliable source.

Then look it up in a meteorology textbook ... I've read that article and can vouch for it ... do you know nothing of sailing on the high seas? ...

Here's the exact same information from NOAA ...

I've never had a problem with Wikipedia's reference material ... at least no more than the CRC Handbook of Chemistry and Physics ... things like the diameter of Mars ... why wouldn't you trust that information on Wikipedia? ...

Anti-learning? ... read the article ... and think of all the latent heat all that water vapor is carrying from the equator to the poles ... the cause is convection, the force is buoyancy ... something thermometers don't read ...

Yeah, I used to race back in the day. J-29s for the most part. But I did an around the world trip with a friend on his Cal 40 once upon a time.

So yeah, I have some experience. And prevailing winds are just that, prevailing, not constant. You can become bacalmed for days at a time. When we were on the Cal 40 we were becalmed for a week smack dab in the middle of the Trade Winds. Normally reliable as hell, but not that week.

I don't use wiki because any person can modify it. So I use my books for the most part. And yes, I have a CRC.

I gave other citations ... all of which confirm winds drive surface currents ...

It's an encyclopedia ... not a citation ... I get that ... but it's a nice tool in the toolbox ... if the information is the same as CRC, what's the problem? ... it's 7,800 km whether we look at Wiki or Bulfinch's ... or whatever books you have ...

 

[ding]

Changing ocean currents caused them. When heat is circulated from the Atlantic to the Arctic, the northern hemisphere deglaciates. When heat transport from the Atlantic to the arctic gets disrupted, the northern hemisphere glaciates.

Surely you are aware that Northern Europe is much warmer than it should be, right? Take away the Gulf Stream and Europe’s climate is much colder. Frigidly cold.

^^^^^^^

is arguing "water causes ice"

Minor problem = water is too warm to cause ice

Yes, surface currents are down to a 100 meters, tops. Variable, and generally quite weak.

How do you know? Present your evidence. Right now everything you are presenting is correlational.

Correlation does not equal causation.

Cause of D-O events.

But common sense ought to tell you that the only thing capable of creating 8C swings in temperature over 30 year periods is the AMOC switching on and off. And there were something like 25 of these events.

What? Your ocean currents only exist thanks to the energy from the Sun. Common sense says that big old yellow ball has that sort of power.

There are no abrupt changes in the sun that can be the cause for abrupt climate changes on earth.

You do realize that 'sudden' climate changes on Earth take hundreds of years to develop.

You do realize that do you not?

Not D-O events. And not from what the models predict for AMOC switch off. So no. And then recently there was the little ice age.

I have probably posted no less than 5 studies on abrupt glaciation and or abrupt deglaciation over the last year and all had physical evidence for changes in ocean currents.

And I bet I could find a bunch more.
