Global Warming Did Not Cause The Storms, Says Senior Met Office Expert
\By Guest Column Dr. Benny Peise
Quote:
One of the Met Office’s most senior experts yesterday made a dramatic intervention in the climate change debate by insisting there is no link between the storms that have battered Britain and global warming. Mat Collins, a Professor in climate systems at Exeter University, said the storms have been driven by the jet stream – the high-speed current of air that girdles the globe – which has been ‘stuck’ further south than usual. Professor Collins told The Mail on Sunday: ‘There is no evidence that global warming can cause the jet stream to get stuck in the way it has this winter. If this is due to climate change, it is outside our knowledge.’—David Rose, Mail on Sunday, 16 February 2014
Okay, I know darn well some posters are gonna go out of their way to “prove” how wrong this is and I don't have the technical knowledge to decide if they're right or wrong; I'm must posting this as an example of how many different “experts” have opinions on this subject.

Move Over Polar Vortex: A Tale of Two Extreme Storms
By Tom Yulsman | February 14, 2014
Yeah, I'm sure you know more than all the scientist there.
What about the "wavy" jet stream from 1918. Was there a "human signature" then?
Funny that there were similar SST's in the winter of 18' that produced an almost identical temperature pattern as this winter
Or January 1977 when the jet was also similar and heights were actually much warmer in Alaska than it is now, and with higher levels of Arctic Sea Ice?
and we were in a negative PDO in both those winters as is the case now. Quite a coincidence wouldn't you say? PDO ENSO years tables
Not saying we don't have an influence on weather patterns (especially on a local scale), but the 3000 pound elephant in the room are the oceans. They drive global weather patterns.
And yes, scientists, credible scientists don't all agree that humans are now in control of the jet stream. The jet stream wobbles and waves according to the oceans temps always has and always will. Arctic Sea Ice certainly plays a role too, but if we conclude that less sea ice today caused this cold winter here, then what about the more sea ice in the 60's and 70's that also caused cold winters right??

Did u watch the video? The reason being cited is the warming of the arctic which is fact. Do u deny the arctic has warmed?
Yes. Of course they shot it on location from Chi-Town

But if you look at the analogs, we can see similar wavy jet stream patterns in the past. So what makes this current one anthropogenic, or blame it on an Arctic that is 1-2C warmer on average then it was during the 1950's?

Yes it has warmed in the Arctic..... Except for Alaska, which has been cooling thanks to the PDO shift

As globe warms, Alaska is cooling down

Fairbanks, Alaska (UPI) Jan 07, 2013
There is expected to be little respite in the coming few days with the weather office forecasting that chilly conditions will prevail.
The unusual cold has been attributed to dense fog which has obscured the sun and disrupted airports and trains, as well as icy winds from the snowy Himalayas to the north.
Winter in the Indian capital, home to 16.3 million people, usually lasts through January before giving way to spring and summer, when temperatures regularly rise to 45 degrees Celsius (113 degrees Fahrenheit).
Despite a global trend of warming climate, Alaska has been experiencing a widespread cooling pattern for at least a decade, scientists say.
.
Do you realize that there is almost no light for many weeks in the Arctic in the winter, and that it is still cold as **** and is mostly ice covered?
and that 8000 years ago, with half the co2 in the atmosphere, the Arctic had half the sea ice it has today for centuries?

Large variations in Arctic sea ice: Polar ice much less stable than previously thought, study finds
For the last 10,000 years, summer sea ice in the Arctic Ocean has been far from constant. For several thousand years, there was much less sea ice in The Arctic Ocean -- probably less than half of current amounts, according to a new study.

More like a quarter less co2, and the Arctic got somewhat stronger summer sunlight back then due to orbital cycles (earth was closer to the sun in northern hemisphere summer).

Holocene Optimum co2 levels were between 260-280ppm. We are now at 400ppm. So about a third less. We split the difference

Why not read the proceedings from the meeting instead of parroting Bastardi.
