Global warming?

There's a mini ice age coming, says man who beats weather experts

He has a flair for writing.

In a few brief hours, we are told, the snowy superfortresses will be above us again, bomb bays bulging with blizzard. It may be that in the next hours and days we have to step up our de-icing, our gritting and our shovelling. So let me seize this brief gap in the aerial bombardment to pose a question that is bugging me.

EU weather troubles blamed on a shifting jet stream. Interesting.

The jet stream shift is related to polar warming.

[TheMercenary]

How can you prove that?

I thought it was related to Al Gore.

[Pico and ME]

I googled it. You can too.

But, but, Pico, I thought you were an EXPERT!

Not possible! You are our resident EXPERT!

First you have to accept that it is not a natural event.

eet the global weirdos. They’re the ones telling you that all the snow outside is proof that it’s getting warmer. Only, they don’t call it “warming” anymore.

No, that was back in the “Earth has a fever” days. Back when Al Gore was predicting that the ice caps were melting, the polar bears were drowning and Manhattan would sink beneath 20 feet of water “in the near future.”

But then something happened. Since 1998, temperatures have been relatively flat. We’ve got more polar bears than ever, and Manhattan is buried under snow. For a planet-roasting crisis that threatened the human race with extinction, there doesn’t seem to be much actual warming.

ok let me get this straight. refineries, cfc's, humans are causing global warming. hmmm ok...there may be some relevance to that but what about when the asteroids hit and wiped out the dinosaurs? it left a cloud of dust and smoke that obliterated the sun from the earths surface. everything froze. finally the dust and smoke settled then things started warming up a bit. over the thousands of years it's still getting hotter, though mind you some years were colder or warmer than others, but the ice age from a historical point of view was caused by the as i'll call it blackout. things take time to heal. the earth is going to heal. it's going to warm up. ice core samples have proven that the earth has gone through a plethora of temperature changes. to say man caused them? i call foul.

from cnn no less

Other scientists and observers, a minority compared to those who believe the warming trend is something ominous, say it is simply the latest shift in the cyclical patterns of a planet's life.

The average surface temperature has warmed one degree Fahrenheit (0.6 degrees Celsius) during the last century, according to the National Research Council.

now fromhere

A new theory to explain global warming was revealed at a meeting at the University of Leicester. The controversial theory has nothing to do with burning fossil fuels and atmospheric carbon dioxide levels. According to Vladimir Shaidurov of the Russian Academy of Sciences, the apparent rise in average global temperature recorded by scientists over the last hundred years or so could be due to atmospheric changes that are not connected to human emissions of carbon dioxide from the burning of natural gas and oil. Shaidurov explained how changes in the amount of ice crystals at high altitude could damage the layer of thin, high altitude clouds found in the mesosphere that reduce the amount of warming solar radiation reaching the earth's surface.

and it goes on....

The Tunguska Event, sometimes known as the Tungus Meteorite is thought to have resulted from an asteroid or comet entering the earth's atmosphere and exploding. The event released as much energy as fifteen one-megaton atomic bombs. As well as blasting an enormous amount of dust into the atmosphere, felling 60 million trees over an area of more than 2000 square kilometres. Shaidurov suggests that this explosion would have caused "considerable stirring of the high layers of atmosphere and change its structure." Such meteoric disruption was the trigger for the subsequent rise in global temperatures.

now in defense....

Many natural gases and some of those released by conventional power stations, vehicle and aircraft exhausts act as greenhouse gases. Carbon dioxide, natural gas, or methane, and chlorofluorocarbons (CFCs) are all potent greenhouse gases. Carbon dioxide and methane are found naturally in the atmosphere, but it is the gradual rise in levels of these gases since the industrial revolution, and in particular the beginning of the twentieth century, that scientists have blamed for the gradual rise in recorded global temperature. Attempts to reverse global warming, such as the Kyoto Protocol, have centred on controlling and even reducing CO2 emissions.

then...

However, the most potent greenhouse gas is water, explains Shaidurov and it is this compound on which his study focuses. According to Shaidurov, only small changes in the atmospheric levels of water, in the form of vapour and ice crystals can contribute to significant changes to the temperature of the earth's surface, which far outweighs the effects of carbon dioxide and other gases released by human activities. Just a rise of 1% of water vapour could raise the global average temperature of Earth's surface more then 4 degrees Celsius.

The role of water vapour in controlling our planet's temperature was hinted at almost 150 years ago by Irish scientist John Tyndall. Tyndall, who also provided an explanation as to why the sky is blue, explained the problem: "The strongest radiant heat absorber, is the most important gas controlling Earth's temperature. Without water vapour, he wrote, the Earth's surface would be 'held fast in the iron grip of frost'." Thin clouds at high altitude allow sunlight to reach the earth's surface, but reflect back radiated heat, acting as an insulating greenhouse layer.

and finally:

As such, Shaidurov has concluded that only an enormous natural phenomenon, such as an asteroid or comet impact or airburst, could seriously disturb atmospheric water levels, destroying persistent so-called 'silver', or noctilucent, clouds composed of ice crystals in the high altitude mesosphere (50 to 85km). The Tunguska Event was just such an event, and coincides with the period of time during which global temperatures appear to have been rising the most steadily - the twentieth century. There are many hypothetical mechanisms of how this mesosphere catastrophe might have occurred, and future research is needed to provide a definitive answer.
