Letter: Last winter was proof of climate change
Thursday 17th March 2011, 6:00AM GMT.
Letter: The harsh winter we have experienced is not proof global warming is not happening but the opposite.
It also shows why the phrase “climate change” is a better term than “global warming”.
Vladimir Petoukhov, a climate scientist at the Potsdam Institute for Climate Impact Research, has recently completed a study on the effect of climate change on winter, published in the Journal of Geophysical Research.
The Arctic has been heating up at two to three times the global average. This rise in Arctic temperature has reduced the region’s floating ice layer by more than 20 per cent.
When the reflective ice and snow layer is stripped away, it leaves a dark blue sea which absorbs the sun’s rays and aids the heating process. As the ocean gets warmer it is in marked contrast with the polar air above. The heat from the ocean flows up into the polar air, creating a high pressure system. This forces the polar air to move and then pushes frigid air down into Europe and across the globe.
Before anyone writes to tell me this is just a hurried and belated excuse to blame global warming for severe winter weather, this paper was submitted in November 2009.

I absolutely support the theory however I caution against claiming any weather event is proof of climate change. The only way to ‘prove’ that a climate has changed with any certainty is to look at the 30 year average.

They said their speculative computer projections predicted warmer winters, due to global warming, but that didn’t happen; the winters got colder. So now they claim their speculative computer projection models predict colder winters due to global warming.
The only way the real world seems to enter into any of these computer projection, is when they see what is actually happening and then change their stories. So now we can all rest easy and get back into our 4 x wheel cars have some proper light bulbs and get rid of all those windmills, as all those scientists who were predicting catastrophic global warming were wrong, burning Co2 actually makes the the world colder.

The letter writer absolutely needs an “In my opinion” in his document.
One winter in one area of the planet proves nothing, other than the high opinion the letter writer has of himself.

In your opinion.

Climate is not the same as weather so merely because the winter was so cold doesn’t invalidate the idea of climate change. In an oversimplification of the case it can be seen as an increase in global temperature and the differences between areas leads to increased winds and the movement of air-masses. This can lead to huge masses of cold air being dumped where they don’t usually belong and vice versa. HOWEVER, I personally am not convinced that humans are primarily the cause of climate change. The climate has been continually warming since the mid 18th century following the mini-Ice Age of the 1600′s. And of course the earth has been warming since the end of the last major Ice Age around 8,000 BC,. Since the start of the Industrial Revolution human activity has dumped many giga-tons of carbon dioxide and other pollutants into the atmosphere but just how much that has infuenced the rise in temperature is still unclear despite the protestations of the quasi-fascist Green movement.

Do you accept Joseph Fourier’s discovery of the greenhouse effect in 1824, Paul?
And do you accept John Tyndall’s experiments proving the greenhouse properties of nitrogen, oxygen, water vapour, carbon dioxide, ozone and methane in 1858?
It’s always interesting to know at what stage people’s scepticism begins and whether they reject the whole canon of climate science or just part of it.

Richard, the Arctic sea-ice reaches it’s minimum extent in September. However, at the North Pole, the Sun drops below the horizon on Sept 25th and doesn’t rise again for 175 days. So there is little or no sunshine to heat the water as you describe.
By contrast the Antarctic sea-ice, which has been increasing in extent, reaches its maximum in September – close to Antarctic mid-summer – when the days are long and sunny. So the increased Antarctic sea ice has a dramatic cooling effect – reflecting the sun back out into space.
So the net effect of recent global sea-ice changes is cooling, not warming.

Amazing! It doesn’t matter what the WEATHER it’s used as proof of CLIMATE. And while the theory above sounds, well, thinly plausible, it’s made to sound as though there 1) a lot of absorptive bluewater and 2) all that heat escapes in the middle of winter, when the area is frozen solid. That kind of dashes the theory on the rocks of timing. And the article was SUBMITTED…but was it actually reviewed by anyone?

Why is it that in the midst of summer at 30,000ft and the temperature outside is -33 degrees, why does this global warming not affect that, why doesn’t the heat rise any more? why doesn’t all this alleged global warming heat the athmosphere by a single degree?

Ask a scientist, perhaps ?

Radiation from the sun (ultraviolet, visible light, near-infrared) passes through the troposphere (the lower layer of the atmosphere that contains our weather) without being absorbed. It’s absorbed at the earth’s surface and some of it is radiated out again as far-infrared (heat that we feel). Some of this is re-radiated back to the earth (i.e. “trapped”: greenhouse effect) and some is radiated away. That’s why it’s warmer near the planet’s surface and cooler as you approach the tropopause (the boundary between the troposphere and stratosphere).

I don’t think anyone doubts global warming is happening and has been since the last ice age.
What is in dispute is the claim that it is ”man made.”
Governments are using a natural occurance as an excuse to raise yet more tax.
Sir Patrick Moore recently told us that there is ”global warming” on Mars.
So the martians are obviously being hit with higher gas, electric, and fuel prices to reduce their carbon footprint !!!

President Obama made no mention of the climate change crisis in his State of the Union Address as Obama knows that the majority of Liberal voters are now former climate change believers. But that DOES NOT mean the Republican deniers won anything since the neocons will always put environmental protection last. So we are left with the same battles of finding new energy, continued pollution controls, population control, environmental awareness, clean water management and promising our children that we will all them a sustainable planet.
And note the “phrase” climate change was not a phrase, it was a scientific theory of runaway unstoppable and deadly continued heating of the planet leaving dire consequences of death for many species besides ours.

Last winter whilst digging my car out of the snow at 5.00 am, in minus 15 degree temperatures, I couldn’t help thinking to myself “One degree warmer and we are all toast”. History shows that the climate fluctuates all the time, the present trend is not unprecedented.

weather = conditions on the ground on any given day
climate = trend of weather over hundreds of years
get it?
its cold outside right now, but it will be sunny tommorrow, the weather is variable in the UK, despite its long term temperate climate
got it now ??

Yes and no – climate = trend of weather over hundreds of years.
The scientist use shorter terms than hundreds of years ie.
Human caused global warming, climate is 30+ years, in general.
But as shown in this letter warmists tend to use any weather event in order to further their own agenda, what ever the weather rain, sun, snow it is all caused by global warming, which of course is is caused by man using Co2. Perhaps that is why the wheels are coming of the bandwagon as far as the people who have to pay are concerned.

Ken, in an earlier discussion you said that the Arctic sea ice was not melting and that it was at the same levels as it was 30 years ago.(http://www.shropshirestar.com/latest/2009/01/20/everyone-will-pay-for-airport/ #62)
Do you stand by this statement?
Shropshire Star readers can compare what you said with this animation of the Arctic Sea Ice extent between 1979 and 2010 on the website of the (US) National Snow and Ice Data Centre.

You can fool all the people some of the time, but there’s always some people you can fool all the time.
In the 1970s they were predicted an impending ice-age, but when it started getting warmer they invented CO2 based warming to “explain” their failure to predict the climate. So it got warmer for a few decades until 2001 when they predicted 100 years of climate warming with warmer winters etc. etc. … since when it has not warmed at all. So now they are predicting colder winters, or is it “weirder winters”.
Let me give a prediction! Like bird flu, swine flu, salmonella in eggs, the millennium bug and a host of other scares that are long forgotten, no government minister will ever admit they were taken in by these scamsters or admit that they wasted billions on trying to solve a problem that clearly did not exist.

Mike, you might be interested in a paper in the Bulletin of the American Meteorological Society (September 2008), ‘The Myth of the 1970s Global Cooling Scientific
Consensus’ by Thomas C. Peterson, William M. Connolley, and John Fleckwhich, which deals with your point.
‘There was no scientific consensus in the 1970s that the Earth was headed into an
imminent ice age. Indeed, the possibility of anthropogenic warming dominated
the peer-reviewed literature even then.’

The reason the temperature at 30,000 feet is tens of degrees below zero is due to the fact that the atmosphere is very thin. Temperature is a measure of how energetic the particles in a gas are. Fast moving particles equals high temp. Few not very energetic particles bumping into each other = low temp. Strange as it may seem the outer layers of the sun’s atmosphere have a temperature of many millions of degrees Celsius but it’s not ‘hot’ in the way we normally think of as hot because although the gas particles are moving very quickly they are not packed close togther.
