In a recent visit to Steve Goddard’s blog, I came across the post Climate Scientists Always Trying To Rewrite Their Own History. It’s about a Tweet by Greg Laden, in which Laden states:
.@LesJohnsonHrvat @SteveSGoddard @PeterGleick AGW Models do NOT predict southern SEA ICE reduction. You are simply wrong. And confused.
— Greg Laden (@gregladen) December 20, 2013
For those not familiar with Greg Laden, he is a well-known proponent of the hypothesis of human-induced global warming, who writes regularly at ScienceBlogs.
In reality, about Antarctic sea ice, it is Greg Laden who is wrong and confused. Antarctic sea ice has been increasing and climate models say is should be decreasing.
Greg Laden is of course contradicted by the outputs of the CMIP5-archived models. See the post here and the figure below.
And Greg Laden is contradicted by the 5th Assessment Report of the IPCC. See Chapter 9 here, page 6. They write:
Most models simulate a small decreasing trend in Antarctic sea-ice extent, albeit with large inter-model spread, in contrast to the small increasing trend in observations. [9.4.3, Figures 9.22, 9.24]
And on page 45 of Chapter 9, the IPCC writes:
Most CMIP5 models simulate a decrease in Antarctic sea ice extent over the past few decades compared to the small but significant increase observed.
Greg Laden appears to be expressing a belief, not knowledge, which is a common trait among global warming alarmists.
Lenin had a succinct description for the Greg Ladens, Phil Plaits, and John Cooks of a movement:
“Useful idiots.”
Greg Laden’s later response – “The gentleman I was cross tweeting with had no interest, though, in having a conversation, so that really didn’t develop.” – is pure projection, as telling someone they are “simply wrong”, followed by insult, is not a normal method of inviting further conversation. Rather, it appears Greg was the one interested in shutting down the conversation.
SR
Steve: I did continue the conversation, and remained polite. Greg offered only insults, and could not provide any support whatsoever for his position. He ignored all offered proofs against his position.
You mean laden cannot really read minds?
[snip – slayer junk, and way off topic -mod]
the weird thing is that I think the latest IPCC report says that the Antarctic is losing mass very slowly. But the numbers are not really alarming because they are almost in balance if you consider the error bands. It’s like we don’t know.
Extent is not the same as ice volume. I would expect more precipitation in Antarctica because of warmer waters and then more ice as it is till too cold for the ice to melt.
He’s right. A tweet is indeed small enough not to fit his big lies.
I’ve run into this Laden guy on Twitter. His output is generally topped off with expletives and he has the unerring instinct of choosing losing propositions. Clearly has some issues to work through.
And NevenA is never to be heard from again…

That was a great post Steve. It needed saying and it was well said. Damn these twisting twisters.
Wow. Its Revisionism all the way down. It looks like Rob Honeycutt is removing responses. I can’t see any of his posts yesterday. This is after Greg Laden removed most of his (and mine).
So we have Rob revisioning his revisioning of Greg’s revisionisms.

Global sea ice in December? Not only was Steve making out it was the 2nd highest on record for the time of year, but global sea ice is at it lowest during the SH summer. (between December and February)

Global sea ice overall what determines part of the planets albedo, not just what happens in the Arctic. The balance between the two poles is key for the planet, not what just what happens at one pole. We are not going to see a warming in the atmosphere at the poles with ice shielding the warmer ocean/seas. When global sea ice remains high, this new trend if anything could lead to positive feedback and bring back further cooling.
When I was in elementary school back in the good old days, a teacher of mine (actually THE Mrs. Wingo of the cartoon Doug fame, she was a real person and a great teacher), placed this note in my permanent record: “Has trouble discerning what he himself deems correct from proven fact.”
Truer words have never been spoken, and I relied upon them to balance and temper my thinking for my entire career in science.
Everyone should have Mrs. Wingo for third grade.
RS that is funny! I’m a teacher and know of several third graders like that. They often argue with a stop sign.
If we had impartial, professional, journalists and an uncontrolled media it would have all been over years ago. As regards Laden (whoever he is)….the lights appear to be on but nobody is at home.
In case anyone is challenged by this guy the best response starts with the sixth letter of the alphabet and ends in the word off!!!!
On a more serious note
Sea levels rise in Holocene’s and fall in Ice Ages….and just to correct things we are talking about where the sea ice anomally is North and South. Compared with the mean 78-08 the answer is 6% down in the Arctic and over 24% up for Antarctica as of todays published figs. Overall making current Global Sea Ice the 7th largest area in the last 35 years.
