When governments around the world have 78 billion dolllars to prove that the other disbelieving scientists with no money dont know what they are saying is true.
Yet these government scientists have no back up ,they wiil not show their data to support theirclaims or even how they claim to have worked it out...Its a rip off .Even if the Global temperature is going up ,its not humans ,it only takes one volcano to spit out decades of C02 in days..
You believe what you want ..sucker

I was reading in New Scientist that the Anthropogenic Global Warming proponents are concerned about how their industry will survive the predicted global cooling trend for the next decade or two.

The whole Greenhouse Effect raising sea temperatures doesn't stack up. Can someone please explain to me how warm air can heat up cold water, when there's so much more water than air? It doesn't work that way. The only way to heat up that much water is to use the sun. There's been no sunspots for about ten years, and so solar output is higher than norm. Once the sunspots come back, water temperature will cool, and we'll be all worrying about the next ice age again, just like we were in the 1970s.

Global warming.Look at the evidence ,freezing weather in Europe,North Korea had the most snow since records began.Mongolia and China experiencing equally cold weather.Oh Fuck yeah I,m convinced now.
Where do I pay my Carbon Credits for my 4x4 ? Because its all us humans fault for Global Warming,
nothing to do with the sun or any other natural phenonemn (don,t care if I spelled it wrong,can,t be arsed checking the spelling)Our leaders tell us its our fault and we must pay and who am I to question it ?Fuck I dont buy it ,its just another way to tax the sheep...:buggerd:

Like most deniers you base your bias to global warming on your opposition to the carbon credits etc. I agree there is much to be said against the CC tax but to use this as a basis to deny the obvious i.e. melting glaciers, Arctic ice sheets etc suggests a lack of understanding of the basics of global warming.

For example many deny global warming on the basis of cold and freezing temperature. These cold and freezing temperatures occur on a seasonal level and yet NASA have documented that the ten warmest years have occurred since 1997.

It seems to me that many of the global deniers do not understand the difference between weather and climate.

Climate is the temperature that is averaged over a period of time.

Weather is what we get or is forecast for a set period of time.

At the same time, many warmers also do not understand the difference between weather and climate. When there is a particularly high temperature measured at Heathrow and taken imediately behind the jet exhaust of an idling 747, this is portrayed as evidence of global warming.

Many also point to melting glaciers etc as evidence of man's effect on the climate while ignoring that those same glaciers have been in retreat since the end of the last mini ice age and not just over the past 40 years. they also ignore the effect of the PDO which switched in 1998. This is like the tide direction at the beach swithing from an incoming tide to an outgoing one. Its therefore no wonder that the decade around the switch will contain the years of highest overall temperature, just as the decade from 1965 - 1975 contained the lowest of the last half century.

The last time there was a large increase in temperature was in the Middle ages...
Funny that they didn,t have the internal combustion engine back then as far as I know.
It has also been proved that the CO2 levels back then rose after the temperature went up.

It's the speed of the retreat and melt that is different.

Gwigs post was a denial that global warming/climate change is occurring. I suspect and mentioned that this may be due to opposition to carbon credits. It seems to me that now some deniers not only dispute the cause of global warming but that it is occurring at all. My focus now on the subject is not the cause, as there will never be a consensus on this either here or in the scientific community, but on the global effects that global warming will cause.

(I had a graph on this but seem to have lost it. I’ll do a search and see if I can find it. The link covers some detail but the key is the answer to two questions
1 have mean global temperatures risen compared to pre-1800s levels,
2 has human activity been a significant factor in changing mean global temperatures.

I do not believe that the prevalence of global catastrophe forecasts and surge of climate denial is a coincidence. I’m not suggesting any kind of conspiracy here. I believe that the groundswell of climate denial has stemmed from the grass roots opposition too carbon credits ‘tax’ How far this has been pursued by the science community to global warming is conjecture on my part, but I do see a developing trend here.

DIY ocean heating

by Mark Imisides

December 7, 2009

Scarcely a day goes by without us being warned of coastal inundation by rising seas due to global warming.

Carbon dioxide, we are told, traps heat that has been irradiated by the oceans, and this warms the oceans and melts the polar ice caps. While this seems a plausible proposition at first glance, when one actually examines it closely a major flaw emerges.

In a nutshell, water takes a lot of energy to heat up, and air doesn’t contain much. In fact, on a volume/volume basis, the ratio of heat capacities is about 3300 to 1. This means that to heat 1 litre of water by 1˚C it would take 3300 litres of air that was 2˚C hotter, or 1 litre of air that was about 3300˚C hotter!

This shouldn’t surprise anyone. If you ran a cold bath and then tried to heat it by putting a dozen heaters in the room, does anyone believe that the water would ever get hot?

The problem gets even stickier when you consider the size of the ocean. Basically, there is too much water and not enough air.

The ocean contains a colossal 1,500,000,000,000,000,000,000 litres of water! To heat it, even by a small amount, takes a staggering amount of energy. To heat it by a mere 1˚C, for example, an astonishing 6,000,000,000,000,000,000,000,000 joules of energy are required.

Let’s put this amount of energy in perspective. If we all turned off all our appliances and went and lived in caves, and then devoted every coal, nuclear, gas, hydro, wind and solar power plant to just heating the ocean, it would take a breathtaking 32,000 years to heat the ocean by just this 1˚C!

In short, our influence on our climate, even if we really tried, is miniscule!

So it makes sense to ask the question – if the ocean were to be heated by greenhouse warming of the atmosphere, how hot would the air have to get? If the entire ocean is heated by 1˚C, how much would the air have to be heated by to contain enough heat to do the job?

Well, unfortunately for every ton of water there is only a kilogram of air. Taking into account the relative heat capacities and absolute masses, we arrive at the astonishing figure of 4,000˚C.

That is, if we wanted to heat the entire ocean by 1˚C, and wanted to do it by heating the air above it, we’d have to heat the air to about 4,000˚C hotter than the water.

And another problem is that air sits on top of water – how would hot air heat deep into the ocean? Even if the surface warmed, the warm water would just sit on top of the cold water.

Thus, if the ocean were being heated by greenhouse heating of the air, we would see a system with enormous thermal lag – for the ocean to be only slightly warmer, the land would have to be substantially warmer, and the air much, much warmer (to create the temperature gradient that would facilitate the transfer of heat from the air to the water).

Therefore any measurable warmth in the ocean would be accompanied by a huge and obvious anomaly in the air temperatures, and we would not have to bother looking at ocean temperatures at all.

So if the air doesn’t contain enough energy to heat the oceans or melt the ice caps, what does?

The earth is tilted on its axis, and this gives us our seasons. When the southern hemisphere is tilted towards the sun, we have more direct sunlight and more of it (longer days). When it is tilted away from the sun, we have less direct sunlight and less of it (shorter days).

The direct result of this is that in summer it is hot and in winter it is cold. In winter we run the heaters in our cars, and in summer the air conditioners. In winter the polar caps freeze over and in summer 60-70% of them melt (about ten million square kilometres). In summer the water is warmer and winter it is cooler (ask any surfer).

All of these changes are directly determined by the amount of sunlight that we get. When the clouds clear and bathe us in sunlight, we don’t take off our jumper because of greenhouse heating of the atmosphere, but because of the direct heat caused by the sunlight on our body. The sun’s influence is direct, obvious, and instantaneous.

If the enormous influence of the sun on our climate is so obvious, then, by what act of madness do we look at a variation of a fraction of a percent in any of these variables, and not look to the sun as the cause?

Why on earth (pun intended) do we attribute any heating of the oceans to carbon dioxide, when there is a far more obvious culprit, and when such a straightforward examination of the thermodynamics render it impossible.

How else do you think meteorologists make their forecasts for air temperatures? They look at the direction of the airflow that is approaching land and integrate the fetch of that airflow by the sea surface temperature that it flows across. The air temperature is a very close reflection of the SST.

Riffer. The problem that Imisides fails to mention is that of salinity. It's what happens when snow melt and large volumes of water from the ice shelf comes into contact with salted sea water. Ask him about the methane riseing and it's future effects on the atmosphere. Being an industrial chemist he should know the effects of mist and oxygen with methan and a lightining strike in the midst of this mixture. I'll see if you tube has something on this. Nope the clip I'm looking for has been removed so I'll just have to improvise witj apologies to Private Baldrick
