Climatologist Andrew Weaver of the University of Victoria says the notion that an extraterrestrial impact caused the Younger Dryas "requires an extraordinarily huge leap of faith." He says there were many climate swings during the last glacial cycle; the mini-ice age was simply the last of them and does not require an extraterrestrial explanation.
Actually, he's dead wrong.

Question - what recorded blast started wildfires? Every high temperature blast, that I have seen record of, cooked (sometimes to charcoal) things exposed to them, yet I see no references to fire resulting from them.
:') The flash from a nuke starts fires; such large impacts release similar amounts of energy, and will indeed start fires. Also, the ejecta from the crater are hot, and where they land they can start fires. Massive fires resulted from the Chicxulub impact at the K-T boundary.

It also accounts for the Cheetah. Today's crop is so genetically identical they must have been the offspring of a single male and female about 10,000 years ago.

One analyst suggested it's almost as though a female gave birth to cubs deep in a den while all the world above was destroyed along with the Cheetahs running around. A massive widespread tsunami would do the trick every single time (provided these animals preferred very flat alluvial plains for their habitat).

And that he is ~ wrong, wrong, wrong ~ the Lesser Dryas affected North America (almost exclusively) ~ and interrupted the normal ice cap meltdown cycle that would otherwise have happened.

How you fellows can joke about this is beyond me.

It is obvious to any sensitive human that Women, Children, Members of Minority Groups, and the Gay and Lesbian Community suffered the most when Halliburton's shoddily constructed ice dam let go without warning.

If Hillary is not elected, this could easily reoccur, driving gasoline prices beyond the ability of illegal aliens to pay.

"I hadn't heard of the Antarctic Meltdown, but that also could account for evidence of 1000 foot waves throughout the world."

I've read that when the fresh water ice dam broke at Hudson bay that the water rushed out then the humungus ice sheet covering the lake broke in half and it too rushed into Hudson Bay causing outrageous tsunamis. The water level worldwide was raised by a foot overnight.

12,900 years ago is but a blink of the eye regarding Earth. Yet the world was such a different place back then. One can only imagine how Earth will be 12,900 years from now!

The immensity of it all amazes me sometimes. The Earth has been here for so very long. And yet, we are the first to be able to think and wonder.

A comet expoding over Canada wouldn’t explain the extinctions of megafauna in South America that happened at about the same time.

Here in the Pacific NorthWest we have ample evidence for the floods, up to 120, that created the WA state scablands and deepened the Columbia River. All of the western Montana valleys were full of meltwater, held back by an icedam near Thompson Falls. Periodically it would break, sending cubic miles of floodwater racing to the pacific. Spokane falls is a result of that deluge/gouging action.

Mt Saint Helens happened in 1980, there is ample proof of a 300 foot high wave that hit the Olympic peninsula/Pac NW coast hundreds of years ago, caused by the Cascadia fault. Point : natural forces operate on their own timescale, chicken little algore and his fearmongering has nothing to do with causing it, it’s Mother Nature doing her thing.

I couldn't agree more.

We experience the El Nino phenomena every few years, and scientists still haven't determined its cause. My own theory is that it is caused by a "hot spot" of magma below the crust in the Pacific Ocean. Some tremendous heat source is required to raise the temperature of the ocean by 3-5 degrees.

You might have something there. You know of course about diapurs(not baby diapers) and hot spots. The fixed hot spot out in the middle of the pacific plate causes the hawaiian island chain. Even now the new volcano south of the big island is a third of the way to the surface.

Diapurs are sort of like low 9 cumulonimbus thunderhead clouds of hot rock welling up from deep in the mantle, possibly the outer core/mantle interface. In Hawaii it breaks thru the thin oceanic crust but here, in these 2 warm pools of water, it may not be strong enough to break thru but spread under the crust like that thunderhead.

Easily checked though : measure heat flows directly under these 2 ocean pools of warm water, all the way down to the ocean floor. It is only 2 things, either geothermal or a solar heating gyre that forms in much the same way as the great red spot on jupiter, or the sargasso sea gyre.

Interesting point though, el nino COULD be caused by geothermal diapurs...go LOOK.

Wow, you have the technical knowldge that I lack.

But it's amazing what a little common sense, applied to some basic information, can accomplish. It was the awareness of the hotspot forming the Hawaiian Islands that led me this conclusion, plus observation of lava lamps, lol.

I am not familiar with the term diapur, but I am going to investigate this, particularly the information about the area south of the Hawaiian chain.

Thanks.

I have read about the evidence for the Cheetah going through a genetic bottleneck, as well.

It accounts for their extreme photogenic appeal, in that they are virtually identical and make fascinating group photos.

Do you think that members of the transgendered community, which you so negligently failed to mention, are not as adversely effected as those other groups?

Ah yes, HAWAII : spent about 5 winters in a row there as my mother’s companion. For about 20 years(winters)she led a singing group on waikiki beach, sort of an aloha-welcome wagon thing. Ukes, leis, hawaiian dancing on the sun-splashed shore. It REALLY pays off in FEBRUARY when you know back home they are freezing their bippies off.

Yes, unique place and people come from all over the world to be there. I did get to visit the observatory on mauna kea one year. It is in fact the largest mountain on the earth as the base starts 2 miles on the ocean floor, peak at 13,800’. In addition to astronomy they do geotechnical work there as well. They send me periodic announcements.

The activity at the kiluaea crater, on the south shore of the big island, has been tapering off in recent years; the hotspot/diapur lava flow is shifting more to the new volcano to the south. Wait a million years and you’ll see it break thru the ocean’s surface.

Which just goes to show that the earth is doing its dynamic, organic thing; volcanism occurs on venus, mars, jupiter’s moon Io, elsewhere; and those planets never heard of algore and his “we’re the center of the universe” nonsense. Volcanos will continue erupting, earthquakes will continue a-shaking wheather you pray to the earth as a god or see it as fraternal twin to venus that got a lot of lucky breaks, for us.

Funny, even though LAND is limited in HI, the natives wouldn’t even THINK of grinding up fresh lava flow-fields, to make fertile fields, that’s sacred pele’s breath. Hey, you can’t even WALK on that ****, it’s like broken glass. It would take you an HOUR to get 100’ on it. So, folks like that are algore’s natural prey....

The main theory is that Hudson Bay is where the last of the gigantic Laurentide Ice Sheet melted. The ground underneath was compressed for so long by so much pressure, it has yet to rebound to its former altitude. Measurements seem to point to this, as the whole area is still rising (also, the Baltic Sea in Europe is a similar remnant that is still rising).

Some of my best friends are transgendered and should Halliburton Ice Dam let go again, rest assured that I shall immediately surrender my seat on the rescue helicopter to him/her/it.

Part of the evidence developed in the debate over where modern humans originated was the number of different mitochondrial DNA types found in different groups, and which ones each group had.

The "Out of Africa" thesis rests on a count showing that Africans have many more types than do other groups, and that all types have a source or counterpart (little changed) among Africans.

By conveniently forgetting about this comet which killed off tens of thousands of small settlements and tribes throughout the Northern Hemisphere, the sample got biased.

It's pretty clear that Africans would end up with more types of mitochondrial DNA than others simply because they weren't eradicated by the comet.

In fact, the latest "trail" out of Africa hypothesized by analysts in the field looks more like the outer limit of a blastzone than it does a "trail".

The Sa'ami and Eskimo ability to deal with vast quantities of seal meat and sea mammal fat suggests that at some point the only folks to survive the comet were hidden in caves, or under cliffs, and when they emerged there was nothing to eat but sea mammals.

With all the DNA testing that is presently going on, I expect some real suprises in the next few years.

I have come to the conclusion based on various inputs that there was something bad that happened about 8,000 years ago. Can you recommend any links?

Genesis ~ oldest story ever about a flood that reached to the mountains.

The Alaskan Earthquake back in the 1960s caused some Tsunamis that reached over 1,000 feet.

There were undoubtedly smaller floods.
