Busy Hurricane Season is predicted for 2024

You are dodging any discussion of your ORIGINAL CLAIM because it FAILED and you're just too much of a COWARD to admit to it.

Tilt away, Donny.

I'll just keep posting the science how changes in ocean currents can result in abrupt 5C to 8C temperature swings both ways.

These peer reviewed scientific papers say otherwise. They say the ocean is responsible for abrupt temperature changes.

And this statement simply confirms that you are a coward and a liar. Neither of us have been able to locate a source that said anything OTHER than Milankovitch orbital forcing has been the initiator or the glacial-interglacial cycle, the original topic of this conversation [See the "Pliocene Era" thread, post 135 where you claim ocean currents are responsible for all climate change in the last 3 million years]. You're a coward because you have dodged the actual conversation when you found yourself losing it and a liar with your claims that the conversation has always been about "abrupt temperature changes"

The most recent ice age was characterized by rapid and hemispherically asynchronous climate oscillations, whose origin remains unresolved. Variations in oceanic meridional heat transport may contribute to these repeated climate changes, which were most pronounced during marine isotope stage 3, the glacial interval 25 thousand to 60 thousand years ago. We examined climate and ocean circulation proxies throughout this interval at high resolution in a deep North Atlantic sediment core, combining the kinematic tracer protactinium/thorium (Pa/Th) with the deep water-mass tracer, epibenthic δ13C. These indicators suggest reduced Atlantic overturning circulation during every cool northern stadial, with the greatest reductions during episodic Hudson Strait iceberg discharges, while sharp northern warming followed reinvigorated overturning. These results provide direct evidence for the ocean’s persistent, central role in abrupt glacial climate change.

The idea of Gulf Stream slowdowns as a mechanism in climate change is not merely theoretical. There is actually evidence from the study of ocean sediments that deepwater formation in the north Atlantic was diminished during the sudden cold Heinrich events and other colder phases of the last 130,000 years, including the Younger Dryas phase (e.g., Fairbanks, 1989; Kennett, 1990; Maslin, 199x). The same appears to have been true further back in time to 1.5 Myr ago (Raymo et al. 1998). The process also 'switched on' rapidly at times when climates suddenly warmed around the north Atlantic Basin, such as at the beginning of interstadials or the beginning of the present interglacial (Ramussen et al. 1997). Decreasing deep water formation occurred at times when the climate was cooling towards the end of an interstadial, and it diminished suddenly with the final cooling event that marked the end of the interstadial (Ramussen et al., 1997), and over a period of less than 300 years at the beginning of the Younger Dryas (e.g., Berger and Jansen, 1995).

You need to face the fact that changing ocean currents explain all of the climate events of the past 3 million years.

This was not the beginning of this argument. This was your attempt to dodge your losing proposition that changes in ocean currents were responsible for virtually everything seen in the geological record for the past 3 million years. Now you want to pretend you never said any such thing. That makes you, as I just noted, a LYING piece of SHIT.

The last ice age wasn't one long big chill. Dozens of times temperatures abruptly rose or fell, causing all manner of ecological change. Mysteriously, ice cores from Greenland and Antarctica show that these sudden shifts—which occurred every 1500 years or so—were out of sync in the two hemispheres: When it got cold in the north, it grew warm in the south, and vice versa. Now, scientists have implicated the culprit behind those seesaws—changes to a conveyor belt of ocean currents known as the Atlantic Meridional Overturning Circulation (AMOC).

These currents, which today drive the Gulf Stream, bring warm surface waters north and send cold, deeper waters south. But they weakened suddenly and drastically, nearly to the point of stopping, just before several periods of abrupt climate change, researchers report today in Science. In a matter of decades, temperatures plummeted in the north, as the currents brought less warmth in that direction. Meanwhile, the backlog of warm, southern waters allowed the Southern Hemisphere to heat up.

AMOC slowdowns have long been suspected as the cause of the climate swings during the last ice age, which lasted from 110,000 to 15,000 years ago, but never definitively shown. The new study "is the best demonstration that this indeed happened," says Jerry McManus, a paleo-oceanographer at Columbia University's Lamont-Doherty Earth Observatory, and a study author. "It is very convincing evidence," adds Andreas Schmittner, a climate scientist at Oregon State University, Corvallis. "We did not know that the circulation changed during these shorter intervals."

Five named storms in the Atlantic and nine in the Pacific. Of those, six have reached hurricane status, three in each basin.

We are behind the forecast (17-25 named, 8-13 hurricanes) but then, the Atlantic has recently cooled almost as dramatically as it had heated up when that forecast was made.

NOAA predicted up to 33 named storms, CSU 23. There was a constant drumbeat of doom. Now? Just shows how much they don't know and speculate on emotion. Its actually very sad to see.
