Since I'm an ice guy, I'm saddened that a place with ice in its name turned out to be unreliable. Still, I wandered over there and took a look at the first article on their main page (as of Aug 3rd, 8 AM) in the 'new and cool' section. The article was http://icecap.us/images/uploads/Examiner_Story.pdf by Joseph D'Aleo (Seems to have been published first on 31 July in the Examiner). In very short order, I found a major error, a cherry pick, and an error or at least misleading graphic. I stopped there.
The first is straightforward error, and the initial red flag is one which needs no special knowledge:
NASA’s JPL reported their 3000 global ARGO diving buoys deployed in 2003 have shown the world’s oceans have too cooled.The thing is, science is done by scientists, not institutions. If he's reading the science, the author would be giving us scientist names (and institutions, perhaps). The scientists involved are at several institutions, as is typical. And, as adults know, scientists do not speak for their employers.
So let's look at the science on ARGO and ocean heat content, and see what's out there. In short order, I found http://oceans.pmel.noaa.gov/pubs.html , which shows two papers with interesting titles:
2006 Lyman, J. M., J. K. Willis, and G. C. Johnson, 2006. Recent cooling of the upper ocean. Geophysical Research Letters, 33, L18604, doi:10.1029/2006GL027033.
2007 Willis, J. K., J. M. Lyman, G. C. Johnson, and J. Gilson. 2007. Correction to "Recent cooling of the upper ocean". Geophysical Research Letters, 34, L16601, doi:10.1029/2007GL030323.
If you go to the web site and select the link for either paper, you'll get both. The comment by D'Aleo, written in 2008, is in accord with 2006's paper. But it ignores the 2007 correction. Since D'Aleo is a fellow of the AMS, it is not plausible that he couldn't know about the correction a year later, particularly as it appeared in the same source as the original.
Immediately following is an eye-catching graph of temperatures (as observed by the MSU, but he doesn't tell us whose MSU data, and there are significant differences between sources). It also plots carbon dioxide levels. The illustration could have come straight from Darrell Huff's excellent How To Lie With Statistics. We're invited to think that the CO2 curve is an estimate of how much atmospheric temperatures are expected to have risen at the time the temperatures were 'dropping'.
0.6 degrees (are those C or F? again, he doesn't tell us something important) seems like an awful lot to expect from a rise of 12.5 ppm (my eyeball estimate from the curve). How much might we expect? Well, suppose that the temperature increase were 1 C over the last century and all of it was due to CO2 (which we don't expect in the science; there are other things going on too). CO2 is up about 100 ppm in that time. Our simplest plausible figure then is that we expect about (12.5/100)*1 degrees warming, or 0.125. The slope of that CO2 curve is about 5 times too large! View the graph again, but for the CO2 line, put your pencil so that it runs from the 0.2 degree tick mark to the 380 ppm tick. That's about the warming we'd expect if you made a lot of assumptions in favor of making this comparison in the first place.
With this carefully selected span the trend line on CO2 and temperature seem to go in different directions. But, now that we've put the two on more comparable footing, we see that the temperature record is highly variable, with 0.6 degrees in 6 months happening at least a couple of times. While you can always draw a straight line through data points, you have to ask whether your line is statistically significant. More to the point here, he should have asked whether that noisy temperature line was significantly different from the smooth CO2 line.
Even better, and more honest, would be to ask just what we expect climate to do in 6 years with only 3.5% increase in CO2. The answer is, hard to say. Solar variability is part of the answer, and the sun has been quiet. That means a contribution to cooling. We also expect that weather happens, and the figure shows this to be continuing in the year to year changes. That is part of why we want long series to consider climate with. 6 years is not long.
A little more subtle, but not specialized, is that we don't expect all the energy that would be captured by CO2 to show up as warming in the atmosphere. Though it's the easiest part of the climate system to measure, the atmosphere is not the only part energy can go to. Energy can go in to heating the ocean, land, and melting ice, for example. We've all hear in the last few years of record melts in the sea ice and ice sheets.
So our unreliable source is:
