Paul Homewood notes: According to John Cook, Antarctic sea ice has been expanding because the Southern Ocean is getting warmer. He also claims that anyone thinking more ice is due to colder conditions is “ignorant”.
He forgets that some of us know how to check the data.
Bob Tisdale produces analyses of sea surface temperatures each month, and these have shown that the Southern Ocean has been getting considerable colder since 1981, and particularly in the last 8 years.

Now who looks “ignorant” Mr. Cook?

:”He forgets that some of us know how to check the data” He also forgets that some of us have studied physics.
The data shows us that the past 12 months—October 2013–September 2014—was the warmest 12-month period among all months since records began in 1880, at 0.69°C (1.24°F) above the 20th century average.
This breaks the previous record of +0.68°C (+1.22°F) set for the periods September 1998–August 1998, August 2009–July 2010; and September 2013–August 2014.

Only by adjusting the data as this graph shows. The current adjustments are even more extreme, cooling the past as well as warming the present.

Even if that were true in reality (versus adjusted reality), there is no proof that man is the cause of much, if any, of it, nor is there proof or evidence that it’s bad. The 1930’s were the warmest years on record at the time, but I doubt that it caused the kind of alarmist reaction that we see today.
“The 1930’s were the warmest years on record at the time” In the US it was, but not globally. Right now globally it’s the hottest 12 month period on record since 1880. Cool hey!
By how many 100ths of a degree? If it is so warm why has no one bothered to tell antarctica?
Antarctica is not the whole globe ya know!
