On a serious note. I don’t think there are too many huge cold lakes like that anymore. Icepack melting is not going to happen in the blink of an eye.

something similar could happen with equal abruptness as the planet warms under human influence There is no huge inland lake in Canada behind the ice dam. They must mean something other than what the word 'similar' means.

10,000 years ago is but a moment ago on Sagan's cosmic clock. The real key to the story is that we "recently" came out of an ice age and who is to say that the coming out is finished? They have unknowingly admitted to a natural warming cycle in publishing this scare story. I'd be more worried about when that giant ice sheet that extended all the way down to Long Island Sound was going to return.
And latest NIE notwithstanding, Nuclear Winter will cure Global Warming long before the temp has gone up more than a degree to two.

They say the findings show modelling studies are right to suggest that something similar could happen with equal abruptness as the planet warms under human influence.
Dang, they're right! That huge glacial lake held in place by the glaciers spreading from Maine to British Columbia could go at any time!!

BIAS ALERT!
I'm still waiting for this "Scientific" proof!

What caused the rise in temperature 10,000 years ago that caused the alleged flood?

Icepack melting is not going to happen in the blink of an eye. Especially since the total amount of fresh water ice is actually increasing, right now.

They have unknowingly admitted to a natural warming cycle in publishing this scare story. If you dig a little deeper you'll find they believe this catastrophe was George Bush's fault.

They say the findings show modelling studies are right to suggest that something similar could happen with equal abruptness as the planet warms under human influence. The film The Day After Tomorrow, which portrays such a scenario, may have exaggerated but not by much.As soon as I got to this paragraph I knew the article could not have been written by a scientist. That is such an infantile leap of pure faith in "the agenda".
The creator of The Day After Tomorrow candidly confessed that he was science-ignorant, and he made up scenarios based on their dramatic visuals, rather than any grounding whatsoever in the natural sciences, climate science or physics of any kind.
It's going to take a lot more than an ignorant assertion that "man made" global warming can be compared (how exactly?) to a gigantic natural process.
Aside from that, it is a fascinating subject. Ice age dams bursts are being found and verified world wide, not the least of which is our very own Lake Missoula...

I first read of the scientific speculation that the Gulf Stream could shut down in the mid 1980’s when the first mumblings of Global warming began to circulate. The argument is that the thermocline which powers the down-welling of the current in the upper latitudes will be shut down by the lowered salinity of the Arctic Ocean from melting sea ice.
That was at least 24 years ago.
Now I will concede that there has been considerable Arctic ice melting in this time frame, yet we see no abatement of the Gulf Stream flow. Nor will we, given the current rate of melting, as it is all things considered, incremental, not catastrophic. A catastrophic event in the past, is not evidence of a catastrophic result from incremental events today.

The study also shows that the changes were abrupt, happening within a decade or so, in warm climate conditions not unlike those of today.I want a lot more documentation and back-up math for this statement before I even begin to take it seriously.
One decade represents 0.125% (0.00125) of 8000 years.
Convince me that sediment cores can be read to that kind of resolution.
That alone casts serious doubt about anything else that is claimed.

“Catastrophic” could also be an event such as a prolonged solar flare, quickly warming the Earth by seveal degrees, not, as we have today, by hundredths of a degree.
Or, there could be another volcano such as Krakatoa in the late 1800s...

they know for sure that this catastrophic event shut down the Gulf Stream and cooled parts of the northern hemisphere by several degrees for more than a hundred years. But that's nothing compared to the damage that humankind can do to the earth unless we empty our pockets and give it to the cause and live as paupers for the rest of eternity. ; )
What humankind can do to change the nature of the earth is at least ten billion fold what the creator of it can do to change it via nature. /s
It's not nice to fool Mother Nature but IF the "fooler's" have enough cash flow, look out ma!

...cooled parts of the northern hemisphere by several degrees for more than a hundred years. Yep, that is a CATASTROPHE!
A few degrees! For a hundred years! Run away!
Frankly, I'd have thought the impact would have been far greater...
