Greg Laden Once Again Expresses Something Other Than Fact

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:

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.

    I had posted on the AR4 and TAR, plus the CMIP5 models. I also added your reference to the AR5. Sorry, I should have addressed to you as well.
