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.
All of Bob’s data is sourced from the KNMI website here.
Now who looks “ignorant” Mr. Cook?
