Let’s do the math!

Roger Pielke’s post which we criticized now has seven updates. Seven! He has protested, I would even say whined, that I and my readers have treated him unfairly. He has accused me of a lack of “professional courtesy” for such horrible deeds as blogging under a pseudonym. He even went to the trouble to dig up my real name and post my hometown location on his blog. How professionally courteous of you, Roger. That certainly advances our understanding of sea ice trends.

Do the Math

Roger Pielke Sr. claims that northern hemisphere sea ice has not declined as fast as computer models predicted. Yet we’ve often heard the opposite, that northern hemisphere sea ice is declining faster than predicted by computer models. How does Pielke arrive at the opposite conclusion?

Defense Against the Dark Arts

This has spawned considerable speculation, and concern, about sudden increase of methane concentration in the Arctic due to extreme Arctic warming, which could potentially cause a nasty global-warming feedback since methane is a potent greenhouse gas. That some are very concerned is no surprise.

Nothin’ but Noise

Pat Michaels claims (also here) that the journal Nature has lost its credibility. That’s an extraordinary claim, considering that Nature is one of the most prestigious peer-reviewed science journals in the world. There are those who believe Pat Michaels is the one lacking any credibility.

Roy Spencer, man of mystery

Apparently, Roy Spencer believes that warming indicated by data from the USHCN (U.S. Historical Climate Network) is almost entirely false. He likewise distrusts the trend for the U.S. estimated from the CRUTem3 data. More to the point, he seems to think that warming over the U.S. for the last several decades has been negligible. All but a pittance (a mere 0.013 deg.C/decade), he says, isn’t real, it’s just due to “adjustments.”

For decades, one of my most revered heroes (heroines if you prefer) has been Jane Goodall.
