Is it sensationalism to tie the colossal squid discovery with global warming? Discuss.

As far as I can tell, yes, this is sensationalism. I see the effects of Global Warming across the globe, but the recent encounters with large teuthids in polar regions strike me as being the byproduct of entering new areas and encountering the denizens. Commercial overexploitation of the globe's fisheries this may be, but global warming bringing up these large squid it is most probably not. But if an expert can persuade me otherwise on this, I welcome the conversation.

For cold-water species, global warming will contribute to their demise. Indeed, this latest example reflects our expansion into hitherto little-trawled/fished environments.

However, temperate to tropical squid have been referred to as environmental barometers, and work published by Dr George Jackson (I believe) certainly points to their increase in size in warmer, more recent years. It is quite possible that for some species the warmer conditions that we are experiencing will result in faster growth rates and greater size, but I must stress SOME species.

I quite liked that article!

Is this the one Steve,

Jackson GD & Domeier, ML 2003 The effects of an extraordinary El Nino/La Nina event on the size and growth of the squid Loligo opalescens off Southern California. Marine Biology. 142: p 925-935.

'Twas most interesting!

Without commenting much on the main thrust of the article (I'm not a vegetarian and strangely enough I AM aware that meat and fish comes from living animals). I'd agree that linking the colossal squid to global warming is sensationalist. Yes we did not previously catch these, but that is almost certainly due to the fact (which is alluded to in the article at one point) that we only recently started fishing in that area/at that depth.

Re: the article that started the thread; the Meso hauled up by the longliner most likely did not "fight for two hours" but just refused to let go of its munchies...

Hmmm the way i see it is the end result of "global warming" is the prevalence of the next "ice age" due to the gulf stream getting cut off by huge quantities of Freshly melted ice. Tho it will get warmer first. So couldn't that make them more abundant. (sorry about the brief/cut down explanation,im tired).

Secondly you all believe in Global warming? Personally i think that its just a trough and crowns in a Milankovitch curves.

As I understand it from the press releases, what took two hours was carefully maneuvering a net underneath it to get it all without totally mangling it and then carefully lifting darn near half a tonne of squid on board. I know arrow squid come apart quite easily in the kitchen, have no idea if the larger squid are similarly delicate. Anyone able to comment on the 'falling to bits' qualities of the biggies?

Not an expert, but I was under the impressiong that 'Global Warming' actually leads to localised climate change in that some places will get a lot colder, some get warmer, some get drier, some get more floods, some get tornadoes when they didn't before, etc. rather than everyone just wearing t-shirts more often.

What I do know is that I shudder to think of what will happen if the major currents start shifting, even with my limited knowledge this sounds......ungood

I've 'worn' many a big one, when moving them around (covered in digestive gland from head to toe). They are probably even more flimsy in construction that the arrows.

Lets use the less news-friendly term climate change, and yes, it does all of that. The last major high temperature spike happened over one hundred thousand years ago - not helped-along by ape-intervention like this current one. The conveyer belt got shut down, and then we got thrust into the last ice age. The major change happened within ten years. That cottage along the British coast you might have been tempted to buy? I don't know, maybe one in the Canary Islands might be more prudent.

Cairnos It would start as a changes to localised weather systems but the end result when the temerature reaches a certain points and the icecaps melt (which is an expinential increase as the albino effect would be decreasing at the same time). The gulf stream (or conveyer belt) would cut off resulting in a Continentaly weather shift. Basically we get wet and cold :wink:.

Was a good post by erich orser and thats the basic (very basic) pricaple of Milankovitch curves.

I think I saw that movie, 'Being John Milankovitch'. Very confusing it was; not sure if I understood it actually.

Watch it again, eat a plate of these, and you'll get it ! (and the runs)



Was talking to a friend of mine who works in the forecasting department locally the other day, and she said to expect the hottest temps on record for Arizona this next year...whilst the midwest of the US might go on for the coldest. Ups and downs, all over the map. :mad:
