Climate change at the poles IS man-made

Maybe if they cut down on the amount of contrails, then we might see a difference, Watch this video to see the scale of the problem


Airplane Contrails Boost Global Warming, Study Suggests

The role of contrails in climate change is still under study, but some scientists believe that they contribute to the greenhouse effect by trapping heat in Earth's atmosphere.

Scientists refute sceptics by proving that human activity has left its mark on the Arctic and Antarctic

Changes to the climate due to human activity can now be detected on every continent, following a study showing that temperature rises in the Antarctic as well as the Arctic are the result of man-made emissions of greenhouse gases.

It is the first time scientists have been able to prove the link between the temperature changes in both polar regions are down to human activity and it also undermines climate sceptics who believe the warming trend seen in the Arctic in recent decades is part of the climate's natural variability.

The findings contradict the 2007 report of the Intergovernmental Panel on Climate Change, which said that Antarctica was the only continent where the human impact on the climate had not been observed.

The new study shows that Antarctica has been caught up in the changes to the global climate over the past 60 years and that this warming cannot be attributed to natural variations.

Using four computer models and data from dozens of weather stations sited around both the North and South Poles, the study conclusively shows that humans are responsible for the significant increases in temperatures observed in the Arctic and the Antarctic over the past half century.

"We're able for the first time to directly attribute warming in both the Arctic and the Antarctic to human influences on the climate," said Nathan Gillett of the Climate Research Unit at the University of East Anglia, who led the study, published in the journal Nature Geoscience.

The analysis has also shown there is a significant change to the Antarctic climate caused by human activity.

Peter Stott of the Met Office Hadley Centre, who took part in the modelling analysis, said: "In both polar regions the observed warming can only be reproduced in our models by including human influences – natural forcings [increases] alone are not enough.

"For a long time, climate scientists have known that Arctic areas would be expected to warm most strongly because of feedback mechanisms, but the results from this work demonstrate the part man has already played in the significant warming that we've observed in both polar regions.

"There was a clear detection in both the Arctic and Antarctic regions of a human influence on the climate. We had shown we had detected the human fingerprint in both regions."

In the Arctic, the most visible effect of warmer temperatures has been the disappearance of the sea ice which floats on the Arctic Ocean. In 2007, the sea ice reached an all-time summer minimum, which was nearly reached again this year.

In the Antarctic, global warming has had the greatest impact on coastal areas and the Antarctic Peninsula, which has seen the greatest increases in average temperatures in the region, leading to the disintegration of ice shelves and the speeding up of the flow of glaciers to the sea.

The picture in the Antarctic has also been obscured by the effect of ozone depletion, which has tended to lower temperatures and so counteract the effect of global warming within the region. However, with the recovery of the ozone layer, scientists are expecting to see even greater increases in Antarctic temperatures in future.

Andrew Monaghan of the US National Centre for Atmospheric Research in Boulder, Colorado, said the study clarifies human impact on two regions that are notoriously variable in terms of climate. "The polar regions exhibit the largest climatic variability on Earth, so detecting and attributing climate changes has been more difficult than elsewhere," Dr Monaghan explained. "The study is important because it formally demonstrates the human contribution for the first time."

But then you have to ask yourself, who benefits from melting ice?

Global Warming Triggers an International Race for the Arctic
As the ice melts, national rivalries heat up over oil and gas deposits and shipping routes

By Thomas Omestad
Posted October 9, 2008

A new epoch is beginning at the top of the Earth, where the historic melting of the vast Arctic ice cap is opening a forbidding, beautiful, and neglected swath of the planet. Already, there is talk that potentially huge oil and natural gas deposits lie under the Arctic waters, rendered more accessible by the shrinking of ice cover. Valuable minerals, too. Sea lanes over the top of the world will dramatically cut shipping times and costs. Fisheries and tourism will shift northward. In short, the frozen, fragile north will never be the same.

Its hard to believe any of these studies anymore, so much disinfo or biased assesments.

We could be causing it or it could be a natural cycle or like I think its a combination of the two.

I live in a northern state climate so I am all for global warming

[Nostalgia]

I go for a combination of the two, KOTS.

[ZingPao]

Who is KOTS TMI?

(Just kidding Nostalgia )

Is it just me or is the spam really been increasing?

[Nostalgia]

I think it is on the increase ZP, they have been busy at it today.

[Nostalgia]

Who benefits? Oil gets pumped-----> oil gets turned to fuel------> Aeroplanes use fuel which creates pollution and contrails trap heat-------->Ice melts-------> Corporations have access to more oil and gas and the north west passage opens up for more trade.
Who benefitted?
Of course, I am just being silly now.

I just realised what you meant, it's my turn to slip up, and that is without a drink!

Do you people have any knowledge of S C I E N C E at all?

Question 001

So, what season was this film taken?

I will go slow enough for you to keep up if I do one simple question at a time.

Lets see, winter?
