What Effect Coming Ice Age on North of 30th Parallel Boating?

"The finding confirms previous data that elevated levels of carbon dioxide in the atmosphere lagged behind the initial warming event - by about 1000 years - and that the principal driver of climate change is the sun, with carbon dioxide ( CO2 ) amplifying the effects."

 

What will the sea-floor be like after the water recedes? Will some areas be mucky like parts of Alabama and some areas form a new Bonneville Salt-Flats deposit? Will new mineral-rich areas become exploitable? How will we manage/compete over these new resources? Will life be easier or more difficult for migrating species? Only time will tell and our part in this cycle has yet to be written.

 

Ice-age temperatures may even have an effect on plate techtonics, as illustrated in this interesting link.: http://www.willmore.net/the_itchy_andes.htm

"We are used to seeing geology control weather, when mountains stop rain from reaching entire regions of the earth, and I suppose we all know how rivers carve valleys. Nonetheless, this is the first time science has shown the weather affecting events deep under the earth's crust....."

"These channels are the main transport pathway for sediments to the deep sea where they form sedimentary deposits. These deposits ultimately hold not only untapped reserves of gas and oil, but they also house important secrets — from clues on past climate change to the ways in which mountains were formed."

 

I was searching for info on submarine Mississippi River when I came across this.:

Has Wellmer been to visit?

submarine river:

"In 2010, a team of scientists led by the University of Leeds used a robotic 'yellow submarine' to observe detailed flows within an 'undersea river' for the very first time. Submarine channels are similar to land rivers, but they are formed by density currents - underwater flow mixtures of sand, mud and water that are denser than sea water and so sink and flow along the bottom. These channels are the main transport pathway for sediments to the deep sea where they form sedimentary deposits. These deposits ultimately hold not only untapped reserves of gas and oil, they also house important secrets - from clues on past climate change to the ways in which mountains were formed.

The team, led by Dr Dan Parsons and Dr Jeff Peakall from the University of Leeds, has been able to study the detailed flow within these channels. Dr Parsons quoted as: "The channel complex and the density flow provide the ideal natural laboratory for investigating and detailing the structure of the flow field through the channel. Our initial findings show that the flow in these channels is quite different to the flow in river channels on land. Specifically as flow moves around a bend it spirals in the opposite direction in the deep sea compared to the spiral to that found in river channels on land. This is important in understanding the sedimentology and layers of sediment deposited by these systems."

It is thought by some that the channels in the Black Sea were formed around 6,000 years ago when sea levels were approaching their current point. The Mediterranean swelled and breached through into the Black Sea - once an isolated freshwater lake - via the Bosphorus Strait. As the waters surged, they carried a dense, salty fluid which formed a network of sea-floor channels that are almost constantly active, even today.

Some people even believe that this was the biblical event Noah's flood, but despite their historical significance, the first spectacular images of these submarine channels were only obtained in 2006 (by researchers at Memorial University, Newfoundland, Canada who are project partners in this study).

The team will use the data obtained to create innovative computer simulations that can be used to model how sediment flows through these channels. The models the team will produce will have broad applications, including inputting into the design of seafloor engineering by oil and gas companies.

The project was led by Dr Jeff Peakall and Dr Daniel Parsons at the University of Leeds in collaboration with the University of Southampton, Memorial University (Newfoundland, Canada), and the Institute of Marine Sciences (Izmir, Turkey). The survey was run and coordinated from the Institute of Marine Sciences Research Ship, the R/V Koca Piri Reis.

The researchers estimate that the river - known as a submarine channel - would be the sixth largest river in the world if it were on land based on the amount of water flowing through it."

"There is no doubt that world sea levels have risen on average some 400 feet since the maximum influence of the Ice Age, although the identification of shore lines at this date around 16,500 BC must be considered in the light of much greater compensatory movements in the earths crust and other factors. Certainly a large island at this latitude would have been a suitable glacial refuge for plants, animals and man, during a highly inhospitable, cold and extremely dry climatic phase with so much of the earths moisture locked tip within Ice sheets."

 

And it is fully demonstrated that the sea levels have not risen in more than 100 years so it seems we are likely at the peak of the warming phase and things are probably going to start getting cold again. BRRR!

 

Yes, and quickly, but Alaskan land-mass will actually increase in size.

 

Thats probaly true ,it was very hot here last week and the tourists were here on the beaches.

 

Is it?

 

It's hardly been 'fully demonstrated.' As a matter of fact, that statement directly contradicts the best available evidence.

I understand I'm not going to change your mind; there's probably no one and nothing that can. But I'll speak up anyway, to keep the record straight.

 

By the way, Hoyt, that's some interesting stuff you've posted about the submarine rivers. I'll have to read up on them.
