BUT

From the BBC (by Richard Black, who by BBC standards is a 'climate denier'):

'Rapid' 2010 melt for Arctic ice - but no record.

Ice floating on the Arctic Ocean melted unusually quickly this year, but did not shrink down to the record minimum area seen in 2007.

That is the preliminary finding of US scientists who say the summer minimum seems to have passed and the ice has entered its winter growth phase. 2010's summer Arctic ice minimum is the third smallest in the satellite era. Researchers say projections of summer ice disappearing entirely within the next few years increasingly look wrong.

At its smallest extent, on 10 September, 4.76 million sq km (1.84 million sq miles) of Arctic Ocean was covered with ice - more than in 2007 and 2008, but less than in every other year since 1979...

The last 12 months have been unusually warm globally - according to Nasa, the warmest in its 130-year record. This is partly down to El Nino conditions in the Pacific Ocean, which have the effect of raising temperatures globally. With those conditions changing into a cooler La Nina phase, Nasa says 2010 is "likely, but not certain" to be the warmest calendar year in its record...

Fortnightly bin collections and a 5p charge for carrier bags have saved the planet! We did it! Good for us.

OR

The great recession has seen global industrial output fall,and trade and transport declined so reducing emissions over the last 2.5 years.

How can the BBC square this?
Recession = greener planet =smiley face.
Recession = PS cuts = sad face.
Answer -- blame the Pope?

BQ: "The great recession has seen global industrial output fall,and trade and transport declined so reducing emissions over the last 2.5 years."

Is that a tacit admission that reducing emissions reduces temperatures? You're 'on thin ice' there, because the article says that 2010 is the warmest year (even though there was more ice than 2007 or 2008).

Either The Pope is Christ's Vicar on Earth and therefore is to blame, or he isn't and is just the fraudulent fop commanding battalions of boy-buggerers. Take your pick.

These 'smallest minimums' and the like can get very confusing, shades of 'tallest dwarf' or 'flattest peak'. Never quite sure how to interpret it, do we cry or cheer?
This one is even worse than usual, since, if my simple engineers brain follows the logic, 2007 was the all time minimum. Since then, there was more ice in 2008, even more in 2009, slightly less than 2009 in 2010, but still more than 07 and 08, so the trend is still upward.
Yet the ice is somehow decreasing (sea ice melts in summer when it gets above 0degC, who knew?), and the arctic will be ice free at some future date if this trend continues. Or not?

Having spent 5 minutes researching (Google) I found this post on WUWT which confirmed my recollection that we started using satellites to measure sea ice in 1979.

That means so we could also say that 2010 was in the top 30 most sea ice years or the 27th highest ever to use a warmist phrase.

Ch, don't knock it these false superlatives. I still get loads of hits for "World's biggest bonsai tree"

SF, damn! I missed that one, despite having pointed it out myself three years ago (plus/minus two days).

A few years ago, when the global warmmongers were on a roll, there was a scare, sorry, theory going round that the reduction in arctic ice would eventually stop the Gulf Stream. It sounded quite convincing, how the warm water of the GS was cooled in the Arctic and froze and the much saltier water caused by the freezing sank to the bottom, making room for more warmer water to come up from the south etc.
When I thought about it, I realised that the GS hadn't packed up in the Mediaeval Warm Period, when it was a damn sight hotter than it is now, or else it would have been the Mediaeval Bloody Freezing Period, so it was all a load of bollocks after all.
