Oceanic and Atmospheric Cooling Started Before Start of Younger Dryas 16FEB2019

 Oceanic and Atmospheric Cooling Started Before Start of Younger Dryas

Hi,

While reading on a slow Friday afternoon,

I came across the below paper.

Levac, E., Sandercombe, S. and Chmura, G.L., 2018.

The Younger Dryas in palynological records from

the northern Northwest Atlantic: Does the terrestrial

record lag the marine and air records?.

Palaeogeography, Palaeoclimatology, Palaeoecology,

 490, pp.269-279.

https://www.sciencedirect.com/science/article/pii/S0031018217307514

In part the the abstract states:

“Major changes in both pollen and dinocyst

assemblages are recorded during the Younger

Dryas in Bay of Islands and are associated with

large drops in air and sea surface temperatures,

and sea surface salinity. The changes in

vegetation are similar with those observed at

other sites in Newfoundland.”

“Sea-surface and air temperatures started

cooling 250 and 110 years before the start of

the YD, hence there is a 140 years delay

between ocean and atmosphere.”

On page 277 of Levac et al. (2018):

“However, we were not expecting a cooling trend

(in sea-surface and air temperatures) that started

before the recorded YD period.”

and

“Not only did sea-surface and air temperatures start

to deteriorate before the start of the YD (respectively

250 years and 110 years before the YD), we also

see a 110 year-lag between the changes in air

temperatures and pollen assemblages.”

and

..and we suggest that the decrease in air

temperatures in eastern Canada started before

the YD period.”

Basically, the cooling trend associated with the

Younger Dryas (YD) actually started before the

official start of the YD period, the time of

the hypothesized YD impact.

How can an extraterrestrial impact effect climate

before it even happens?

Paul H.

Fossil Hunting on the Moon in Terrestrial Meteorites

https://royalsocietypublishing.org/doi/full/10.1098/rsta.2013.0190

https://core.ac.uk/download/pdf/30704804.pdf

The abstract states:
“This is the first demonstration that fossils can survive and be transferred from projectile to target in hypervelocity impacts, implying that
it is possible that, as suggested by other authors, terrestrial rocks ejected from the Earth by giant impacts from space, and which then strike the Moon, may successfully transfer terrestrial fossils to the Moon.”
