What is the status of the Arctic sea ice?

The year 2016 will go down as one with below-normal Arctic sea ice coverage.

While not quite a record-setting year like 2012, throughout much of 2016 the extent of sea ice was more than two standard deviations below the average. At the end of October the Arctic sea ice was at its lowest coverage for the month since satellite-based data records started in 1978. Continue reading

As of Sunday, this year’s string was at 127. Low temperatures forecast around 45 degrees for Monday through Wednesday could maintain or break that streak. Continue reading

Has global warming stopped?

In a recent interview on the Glenn Klein Show on WRJN radio, U.S. Sen. Ron Johnson, R-Oshkosh, asserted that “the climate hasn’t warmed in quite a few years … that is proven scientifically.”

This statement is entirely untrue but echoes a line of argument that many climate change and global warming skeptics have introduced into the discussion for a number of years. The so-called “global warming hiatus” argument suggests that since the beginning of the present century there has been a slower rate of increase in the global average surface temperature than climate models suggested would be the case.
