Prove it.
Science magazines are science journals, idiot. They publish papers and conclusions that contain data and assessments.
Got anything to back yourself up?
I thought not.

Got anything to back yourself up?
I thought not.
Quantified conclusions or corellation implying causation?
Can you quantify through modelling?
Can you quantify through modelling?
Prove anything related to the topic.
Direct observations are quantifiable.
Got anything to support your dumbass denial?
Operational risk.
Who cares about the IPCC? You are the one that brought it up so why should I have to supply info about it? grow up and find it yourself..
BTW, got anything supporting your denial?
Operational risk? That's hilarious
IPCC who cares? Yeah how true. Who really does give a **** about the agency that is spewing bull**** around all willy nilly based on magazine interviews. It's not costing us a ****ing penny or effecting any of our lives.
My denial of it warming continually for 13000 years. Never did deny that.

Prove me wrong then. You wanted an example and didn't specify any particular example.
As far as climate models go, they can provide quantifiable indications and trends. If data supports their predictions then they are decent models.
If you don't think so, that's your problem.
You haven't yet proven that anything has warmed over the past 13,000 years. You haven't proven much of anything, actually.
A prediction isn't a quantified fact. It's still just a guess.
What's to prove? I haven't been asked to prove anything.
Now... wouldn't that be local though?

At any rate. Two weeks ago we had unseasonably warm weather in New England. It was high 70's... beautiful out. The local Liberal talk show naturally had a show that stated that this unseasonably warm weather was a sure sign of Global Warming! People calling in, saying they are afraid etc. and this warm weather CERTAINLY is a sign of Global Warming. One need only go outside and see!
However when the temps dropped backed below the averages... nary a peep!
The alarmists sure love to have it both ways.
There is a reason for this years above seasonal averages and it's not a global issue. It's not the first time these patterns caused very similar conditions. We saw this 80 years ago.
You asked, "Can you quantify through modelling?". Again, you did not specify anything in particular, let alone specify that you wanted quantifiable facts. You got what you asked for.
Bullshyte.
Do you claim AGW is BS? If so, post something supporting your claim.
13000 years of steadily rising temps is all the proof anyone needs. What more do you want? Magazine articles?
Oh well you should have heard them on the radio! Warm weather was a sure sign that MAN was heating the earth to the BOILING point!
yes. However, you mentioned Greenland so I posted some info about it. And it isn't as if Greenland is the only place ice is disappearing from. It's disappearing all over the planet. That weather phrnomenon contributes to and indicates issues in global climate trends.
Record_Lows_2001
Concerning global climate, there's no reason it should garner much of a "peep".
Just like deniers.
Show the temperature figures.
La Nina did the nearly identical thing to N.America in 1930's. Remember the whole "dust bowl" thing? It would be just as dusty if it weren't for better soil management today.
Is 450,000 years worth which includes 4 interglacial events with temps and CO2 levels higher than today good enough for ya or do you want WWF and magazine literature too?
Uhuh. Now you might notice that the temperature scale hit peaks and then goes down. Except for the past little bit. It is still hanging around at higher temps for a longer period of time. That breaks the trend shown in your graph over the past 450,000 years. And it shows no sign of going down any time soon.

Funny stuff. lol
Bering Sea Ice Extent Breaks Records
The Arctic has crossed the threshold from winter into spring. Scientists at the National Snow and Ice Data Center announced last week that Arctic sea ice reached its maximum extent on March 18 and is slowly beginning its summer retreat.
Despite a chilly winter in some part of the Arctic, the overall ice cover was the ninth lowest since the satellite record began in 1979. That’s still a sizeable quantity of ice – 5.9 million square miles, or roughly the size of the United States and Canada combined – but about 200,000 square miles less than the 30-year average.
Most of the missing ice was in the Barents and Kara Seas, above western Russia, where higher-than-average temperatures kept sea ice from forming.
Meanwhile, closer to home, the Bering Sea had record ice cover in February and March and it remains well above average even now, halfway through April.
Walt Meier is a sea ice researcher at the National Snow and Ice Data Center. He says a persistent low-pressure system south of Alaska is responsible for the Bering Sea’s extreme ice.
“Basically what that did, that brought the circulation from the north or the northeast out across the Bering Sea and that essentially does two things. Number one it brings cold air down into the area, so that cold air helps ice form. But it also pushes the ice southward, so you keep pushing the ice edge southward because of the winds blowing from the north.”
Air temperatures over the Bering Sea averaged 11 to 14 degrees colder than usual this winter, which pushed the ice edge as far south as the Aleutians at times.
But the extent isn’t the only unusual part, according to Meier. Heavy ice flow through the Bering Strait created a formation called an ‘ice arch’ several times this winter. It's a little complicated, but basically the Strait acts as a choke point for the ice when it’s moving south. If there’s a lot of ice trying to flow through the Strait all at once, it tends to start piling up and when enough of it accumulates, it locks together in such a way that it creates an arch and stops the southern flow. Meanwhile, the ice that’s already passed through the Strait continues on its southern trajectory, creating a swath of open water between the arch and the rest of the ice pack. Meier says the formation is pretty rare.
“We haven’t seen it happen a lot recently and that may be partly due to… you know, the Arctic used to be covered with older and thicker ice and so that older and thicker ice was stronger and so when it would get crunched together north of the Bering Strait, you would see these ice arches form. That thicker ice is stronger. Lately we’ve seen more thinner, seasonal ice cover that breaks up more easily and probably flows through a little bit more easily.”
Meier says any thicker ice that formed in the Bering Sea this year won’t stick around for long though. The Bering Sea's ice is seasonal and completely disappears by mid-summer. Meier says that makes the record-breaking ice extent less significant in terms of the overall Arctic.
“From a climate perspective, it’s not a big factor in the long-term trends [in the Arctic] and it’s not going to be a big factor in the summer extent this year.”
The last year with similar levels of winter ice cover in the Bering Sea was 2008.
Stick the the 450,000 year and explain why glaciation has come and gone 4 times without man? Coincidence?
