some comments on "The day after tomorrow"
This is what I put on my internet site:
( http://www.euronet.nl/users/e_wesker/dat.html ) __________________________________________________ ______ "The Day after Tomorrow", spectacular & amusing bull**** These days a new (intended) "blockbuster movie" is released: "The Day after Tomorrow". In this movie a climate catastrophe is riding roughshod all over the world. First all kinds of voilent weather is raking numorous places, and then "the big freeze" follows. In my opinion it is a load of rubbish, which might give rise to an opportunity to greenhouse sceptics to ridicule sound climate science done by e.g. NOAA or the KNMI. Therefore I list some details from the movie which are plain wrong or highly improbable. The special affects look good as far as I can see from the trailers available on the internet. From this point of view I may well go to the cinema and watch it. But only in the same way that a looked at James Bond movies: I am looking at unpretentious amusement. Don't take it seriously. Some minor details Tornadoes in Los Angeles In the movie Los Angeles is levelled by huge F4 to F5 multiple vortex tornadoes. This is simply impossible. The sea surface temperatures off the Californian coast are far too low to create the conditions needed to produce such beasts. If there are places as examples where no tornadoes (not even a waterspout) are possible these are the subtropical areas where upwelling of cold water takes place: Marocco, Namibia & the NW of South Africa, California and Peru & Northern Chili. A 300 ft tidal wave generated by a storm A 300 ft tidal wave generated by a "superstorm" sweeps over lower Manhattan. (Buildings do not topple - which is highly unlikely.) Also this is simply impossible. The worst case scenario for New York is a repeat of 'the New England hurricane of 1938' and the eye making landfall slightly South-West of the city, thus sending the worst part of the storm and its accompanying storm surge into the New York harbor. In such a scenario the storm surge will be 30 ft above the normal tide. Lower Manhattan will be inundated, and the subway will be flooded. JFK international airport will be rendered useless due to flooding. So: Quite major inconveniance and some $20 billion economic damage, but nothing like in the movie. The trigger is a big ice shelf breaking off near Antarctica Quite big ice sheets (sometimes as big as 5000 - 10000 km˛!) have broken away from the Antarctic pack ice in recent years. Up to now no appreciable climate effects due to these events have been observed. They are probably a result of the present warming, so a consequence. Secondly: The influence of these events on the sea currents in the Northern Hemisphere is (at most) very indirect. Climate change Climate change doesn't occur in one day. So "the big freeze" in the movie is not credible. The movie is in fact a highly exaggerated version of the Younger Dryas cold wave which occurred 12700 years ago. This was caused by a huge fresh water flood from the Laurentide Ice cap (on Canada) into the Atlantic. Due to this the gulf stream stopped, causing the tempratures in Europe and North America to drop dramatically within 50 years. It was a mini ice age which lasted some 1200 years. 11500 years ago the climate flipped back to normal. Currently the Younger Dryas cold wave scenario is regarded by most climate scientists as highly improbable. A similar conclusion can be found in the last IPCC report. If you want to read some more on the subject of climate change, on this internet site quite a few small articles on it can be found. As a start look at http://www.euronet.nl/users/e_wesker/climate.html A final remark Enjoy the movie, but don't take it seriously. __________________________________________________ ______ Mazzel & broge / kind regards, Evert Wesker Amsterdam, The Netherlands http://come.to/wesker (redirect URL, no adv's), or http://www.euronet.nl/users/e_wesker/ |
some comments on "The day after tomorrow"
I'm intending to post this all in a separate new topic...
I actually saw this movie, in the actual theater. The reason I saw it was mainly so that I could watch the spectacular weather CGI. I was NOT disappointed. There was one scene, in which the residents of the International Space Station (I think its the IIS anyway) look down and several see gigantic cold hurricaines over the Northern hemisphere made it worth my 5.75 matinee expenses (plus I snuck into troy). This was a disaster film, and the script was often corny. Many things were lame. However, I really enjoyed the actors, Dennis Quaid (like harrison ford, but possibly a better actor), and the guy who played Donnie Darko (the best performance of a wierd troubled teenager ever). But I'm not here to do a real film review, I want to talk about science. I was actually able to suspend my disbelief because the movie presented a concept that was so foreign to me that I was unable to really dispute it during the course of the film. I'm still not sure what to think, tho I'd imagine the science is a little (or very) hokey. Perhaps some of you gurus will enlighten me. Be warned: A SPOILER FOLLOWS!!! As a weather geek, if further discussion proves the film is indeed wrong and silly, you may not attain the full level of Joy that I was. Also, Please forgive me for any stupidity/ignorance I may exhibit in my explanation. The root of the meteorology in this: Cold Hurricaines. Also there are definitely a lot more presumptions than the 2 I cover in the following... Presumption #1 (the more hokey one, I think) It all begins when there is a change in the salinity of one of the major currents in the atlantic and also running throughout the world. I do have some vauge recollection of such currents, but I'm a lot more interested in the atmosphere than oceanic stuff. I also recall that salt water rises and so presumably this alters the interplay of cold water The idea is that there is a critical shift in the salinity at some point where there is a confluence of currents. Suddenly, buoys all along the length of the current off the coast of the East US and Greenland start register 13 degree (F?) drops. Presumption #2: Cold Hurricaines... IS THIS REALLY POSSIBLE? I'd guess probably not, but who knows? The idea is that there are gigantic storms that form all over the northern hemisphere (3 to 5). The eyes of these hurricaines exhibit extreme freezing cold, to the tune of -150 degrees (F?). Helicopters crash because of frozen fuel lines and people freeze instantly. They form over Northern Canada and Siberia and stuff, which sounds plausable enough. Has anybody ever heard of such a concept? Also, A month or two ago, the Defense Department released a report which outlined a prediction that global warming would occur followed by ANOTHER ICE AGE. I can't find the link, but it was on cryptome.org. The report was intended to explore global strategy for the US in such a situation. Thanks, Dubs |
some comments on "The day after tomorrow"
John Krempasky (in your seperate entry) gave an adequate answer.
One more comment on the Pentagon stuff: It was just a scenario study ("What, If"). Nothing more, nothing less. It was done by Peter Schwarz, once employed with RD Shell. Over there he did similar jobs: scenario studies for the corporate planning dept.
