This story compares a 1971 National Geographic map of the Arctic Ocean and its icecap with modern satellite data, and finds that the icecap is actually significantly larger now.
Take a look. Then come back to read my analysis.
Back? Okay. First, we are presently in the midst of summer in the Arctic, so the icecap shown on the modern map should shrink somewhat this year. Second, it is not clear what time of year the National Geographic map portrays. Is it maximum ice during the winter? Or they average for the year?
These questions however avoid the bigger point here, which is that there doesn’t really appear to be any significant change overall to the Arctic icecap in the past half century. The icecap had seen some major shrinkage during the first decade of the 21st century, but in recent years it has begun recovering. So much for the many past predictions by global warming activists that the Arctic will be ice free in summer because of global warming, by 2008, 2014, or 2018.
