In one of my meteorology classes I'm taking, today the professor discussed some trends in the rising of carbon dioxide levels in the atmosphere and it's quite easily seen the levels are rising exponentially.

Below is a view from space of the arctic region... the image is pretty much self-explanatory to be honest. That's quite a loss of average polar sea ice for twenty-some years..

Moreover, one interesting point about potential global warming that I'm sure most here have not even pondered is the posibility of global ocean currents shifting course.

If chunks of polar sea ice continue to melt and drop off into the rest of the Northern Atlantic Ocean, there will be a massive temperature swing of the water in the area. Such a drastic temperature change in the water, due to basic fluid mechanics, has the potential to cut-off the normal current in the Northern part of the Atlantic. Or in other words, the current could take a much more southerly u-turn than seen in the image below. If something like this would occur, the meteorological patterns in Europe would change drastically. I'm not talking about just a couple degrees Fahrenheit either... more like potential temperature departures of minus 10 degrees Celsius than what is normally found. And along with this decrease in seasonal temperatures, you could probably expect more brutal winter storms than usual during an El Nino weather pattern, for instance.

Doesn't it just sound lovely, Erik? :weee:

That's the part that freaks me out that most. It's that the heat pump that is the world's ocean currents can switch off or reverse at certain points of temperature sway -- amplifying any effects of any climate changes due to temperatures and CO2 levels, for example.

We know we've seen it in the past from ice cores. And then knowing from geological history that the earth can go from weather patterns like today to global Ice Age conditions in less than about 6-7 years (and this is without the unprecedented CO2 levels we're producing today) is pretty freaky.

Just if I understand your latest avatars, I would share your joy :D

On a serious note now, a few weeks ago Sweden became 8 meters shorter.

It's my homage to the booming personal security/paranoia industry in this country that has particularly flourished over the past 15 years. Don't leave home without your own personal pocket smoke hood.

I take it Ibrahimovic didn't forget to turn off the water running in his bathtub....

    every pound of snow that melts, releases carbon dioxide :disagree:

    this idiot who denied global warming on larry king live was saying how ocean currents are due to winds :D

    The Hellish Vision of Life on a Hotter Planet
    by Mark Lynas

    Buried within the newly released IPCC report is an apocalyptic warning: if greenhouse gas emissions continue to rise at current rates, global warming by the end of the century could total 6.4C. The scientists don't say so explicitly, but a rise in temperatures of this magnitude would catapult the planet into an extreme greenhouse state not seen for nearly 100 million years, when dinosaurs grazed on polar rainforests and deserts reached into the heart of Europe. It would cause a mass extinction of almost all life and probably reduce humanity to a few struggling groups of embattled survivors clinging to life near the poles.

    An eco-alarmist fantasy? Unfortunately not - having spent the past three years combing the scientific literature for clues to how life will change as the planet heats up, I know that life on a 6C-warmer globe would be almost unimaginably hellish. A clue to just how unpleasant things can get is contained within a narrow layer of strata recently exposed at a rock quarry in China, dating from the end of the Permian period, 251 million years ago. For reasons that are still not properly understood, temperatures rose by 6C over just a few thousand years, dramatically changing the climate and wiping out up to 95 per cent of species alive at the time. The end-Permian mass extinction was the worst ever: the closest that this planet has ever come to becoming just another lifeless rock orbiting the sun. Only one large land animal survived the bottleneck: the pig-like Lystrosaurus, which for millions of years after the disaster had the globe pretty much to itself.

    Clues as to how the world looks in a long-term extreme greenhouse state also come from the Cretaceous period, 144 to 65 million years ago, when there was no ice on either pole and much of Europe and North America was flooded by the higher seas. Tropical crocodiles swam in the Canadian high Arctic, whilst breadfruit trees grew in Greenland. The oceans were incredibly hot: in the tropical Atlantic they may have reached 42C, whilst at the North Pole itself, the oceans were as warm as the Mediterranean is today. The tropics and sub-tropics were so hot that no forests grew, and desert belts probably extended into the heart of modern-day Europe.

    During the Cretaceous, of course, species evolved over millions of years to be able to survive on a much hotter planet. Nowadays very few species could survive such a sudden transition. Cold-adapted species like polar bears would obviously be an early casualty, and coral reefs will also disappear from the tropics. The Met Office's Hadley Centre has predicted that the Amazonian rainforest could start to burn as early as 2050, gradually transforming towards desert as temperatures soar in the interior of South America. Ash and smoke would blanket much of the southern hemisphere, and nearly half of the world's terrestrial biodiversity would be wiped out at a stroke.

    How people might fare is anyone's guess. With the tropics too hot to grow crops, and the sub-tropics too dry, billions of people would find themselves in areas of the planet which are essentially uninhabitable. This would probably even include southern Europe, as the Sahara desert crosses the Mediterranean. As the ice-caps melt, hundreds of millions will also be forced to move inland due to rapidly-rising seas. As world food supplies crash, the higher mid-latitude and sub-polar regions would become fiercely-contested refuges. The British Isles, indeed, might become one of the most desirable pieces of real estate on the planet. But with a couple of billion people knocking on our door, things might quickly turn rather ugly.

    Six Degrees: Our Future on a Hotter Planet by Mark Lynas will be published by Fourth Estate on 19 March.



    A very scary article people

    I'm aware of the Gulf Stream, we've been hearing about it slowing down since the late 1980's. As it stands though, long-term and diverse measurements carried out by our dear Confederal leaders in Brussels have concluded the Gulf Stream's main influence stretches no further than the British Isles and Northwestern Scandinavia, that being Iceland, Norway and Sweden, excluding Denmark.

    It's effect on Northwestern Continental Europe, that being the Denmark, the Benelux, France to just South of Paris and the former West Germany is rather limited.

    The slow down of the Gulf Stream would, combined with global warming that would continue as a general process of the Earth's averages, only briefly and moderately cool down Northwestern Europe. Scotland would see significant snowfall again, but the Netherlands wouldn't.

    Since the EU's track record with propaganda is absolutely disillusioning to any fascist, I'm inclined to believe them.

    Sorry :D

    There's lots of creepy stuff going on that we only know so much about. There's no need to panic, that doesn't serve anyone.

    Ever heard of Geomagnetic Reversal? It's a reversal of the magnetic poles of the Earth: meaning North becomes South and vice versa. This switch has happened several times in the past and last time I checked, the next switch shoulda happened some time ago. I don't think I need to spell out the disastrous consequences.

    really worrying when you consider that britains climate is increased by teh gulf stream. i watched a programme recently that showed that due to all the fresh cold water breaking from the icebergs is entering the sea andslowing down teh gulf stream. when you look at scotlands positioning on the globe we could get hit with a shit long winter. they reckon that instead of benefitting from longer hotter summers, britain might end up plunged into another ice age

    kind of what i was attempting to say but in laymans terms, well explained andy. scotland is bloody cold enough i dont wanna be plunged into another ice age
