The special effects were pretty cool. The story is not just far fetched but it is impossible. I kind of wish this movie had come out a month ago so I could hear my physical geography professor rip it apart. Armed with one semesters worth of knowledge in that class (I got an A, by the way) I can tell you why this stuff is not possible. Just ask and I'll get into it.
A teaser...
A low pressure system developing over an area dominated by High pressure? pfft
The SEA water freezing in new york city? (anyone ever make ice cream?)
Instant glaciers? No thats not how they are formed.
Ice ages are predominatly caused by a shift in the angle the earth faces the sun. Which is typically about 22 degrees. It shifts as far as 25 degrees during ice ages. Cooler summers are the cause of glaciers, as they are formed by centuries of snowfall that is not fully melted by the unusually cold summers. The snow compacts into sheets of ice due to its sheer weight.
I think humans are a bit too proud of our own abilities. It takes thousands of years to develope into an ice age and to form SLOW moving glaciers. We are man though, we can do that in a week.
In a different science course, Geology and Natural Disasters, I had the dubious honor of attempting to prove global warming is not caused by humans. There are charts that show the change in temperature mimics the amount of solar energy being produced (I could dig them up if anyone wants to see them, otherwise just look through intellicast.com for info). In fact, in the early 1960's solar energy had decreased so much and temperatures were colder than usual the northern parts of the western and eastern hemespheres that scientists were concerned that the planet may be slipping back into an ice age. There is no substantial proof that the ice ages have totally ended, we could just be in one of the 15,000 year warming periods between ice ages, which can last 100,000 years.
I know that I get too caught up in these movies, and some of you may be able to argue a different point of view, but I can't enjoy a movie in which everything that happens seems totally incorrect.
Cool special effects, horrible story and ungodly acting.
