Climate change is over!

That's right, you (might've) heard it here first. Climate change is over! The ice in the Arctic is increasing back to 2001 levels! Hooray!

Well, sort of, anyways. According to Times Online:
"A shift in the chilly winds across the Bering Sea over the past few months has caused thousands of square miles of ocean to freeze.

The same phenomenon, known as the Arctic Oscillation, is also partly responsible for the cold winter experienced in northern Europe and eastern America.

It allowed icy blasts of air to escape from the Arctic and make their way southwards. Provisional Met Office figures for December to February suggest the UK had its coldest winter since 1979, with an average temperature of 1.6C — a full 2.1C below normal. Last week a teenager was killed in Scotland when a school bus crashed in the snow — just days into British Summer Time."

Well, okay, climate change isn't over. In fact, it's just due to the phenomenom listed there, called "Arctic Oscillation," which is determined by shifting air pressure in the north, which apparently since the 70's has lead to higher than normal temperatures in the northern hemisphere (Europe and North America) due to it being in a "positive" phase.

In other words, this is a natural thing determined by natural forces that our natural-but-hardly-inclined-to-believe-it-is minds can barely understand, predict, or control. However, scientists remain adamant that this doesn't affect global warming/climate change predictions:

"The reality is that greenhouse gases are making the world warmer, but it is a mistake to see short-term changes in weather, currents or Arctic ice cover as evidence of this," Pope said.

"Instead you have to look at long-term trends. These show that Arctic summer sea ice is decreasing by 232,000 square miles a decade, nearly 2.5 times the area of Great Britain.

"On current trends it will still become ice-free in summer by around 2060."
