Gulf Stream shifted north during 12,900-year-old cold snap, first direct evidence shows
During an abrupt global cold snap nearly 13,000 years ago, the #GulfStream #ocean current shifted farther north, temporarily disrupting eastern #Canada's oceanic ecosystems, a process that could happen again as the #climate changes, a new study by UCL researchers finds.
The paper, published in Nature Communications, reconstructed the history of the ocean current using marine sediments recovered off Canada's East Coast. The team found that during a time of rapid and intense climatic change known as the Younger #Dryas, about 12,900 years ago, the Gulf Stream shifted hundreds of miles to the north, bringing it closer to the coast of Nova Scotia.
This northward shift has been predicted in previous modeling studies, but the sediment cores are the first empirical evidence of it during a past major abrupt climate event. The research also provides insight into the sequence of shifts that #Atlantic currents are predicted to undergo because of #ClimateChange, giving scientists better advanced warning of major changes.

Here we are in drought. Parts of New South Wales are flooding after being dry for a long time. And we can't get it to rain.
I am hoping to fix that. I have a guy coming tomorrow to quote me on building a proper creek crossing. That should make it rain 😎
Going to wash both cars and hang the sheets out. Also going to paint some doors outside and invite 100 people for a picnic lunch, just to be sure.

Gab es doch einen Kometentreffer vor 12.800 Jahren? Bohrkerne vom Meeresgrund liefern neue Indizien für einen Einschlag in der jüngeren Dryas. #Dryas #Kometeneinschlag #Einschlag #Impakt #Eiszeit

Nach ihr wurden geologische Zeitabschnitte (Drei Kaltzeiten im Pleistozän) benannt ❤️ - Dryas octopetala, die Weiße Silberwurz. Sie ist ein Glazialrelikt der europäischen Hochgebirge.

Se está desarrollando un debate interesantísimo sobre las causas del #Dryas Reciente.
El Dryas reciente fue un cambio climático muy brusco producido hace unos 13 000 años, momento en el que se interrumpió el calentamiento progresivo desde el máximo de la última glaciación hace unos 20 000 años. En apenas un año (posiblemente) la temperatura de Groenlandia cayó entre 5 y 9ºC.
El cambio duró unos 1200 años y la salida fue casi tan brusca como su inicio.
