(click on the images to enlarge) The image on the left is snow cover in North America at daybreak Weds. AM. Note there are a couple pixels in N. Lower Michigan where there was a dusting (which melted during the day). There is a pretty solid snow cover North of Lake Superior, straight up to the Arctic. The weekend storm will add to that. The second image is snow cover across Europe and Asia. The third is a comparison of snow and ice on 10/20 in 2007 and 2013. According to the National Snow and Ice Data Center, the extent of the Arctic ice reached a minimum on Sept. 13th, when sea ice extent dropped to 5.10 million square kilometers (1.97 million square miles). As the Arctic reached its minimum extent for the year, Antarctic sea ice was reaching record high levels, culminating in a Southern Hemisphere winter maximum extent of 19.47 million square kilometers (7.52 million square miles) on September 22. The September 2013 monthly average was also a record high, at 19.77 million square kilometers (7.63 million square miles) slightly higher than the previous record in 2012. Antarctic ice extent is now more than 2 standard deviations from the satellite era average, while ArHctic ice extent is close to the average for the 2000s. Here’s the average annual temperature at the South Pole since the 1950s. Here’s a video of the Southern Lights at the S. Pole. Here’s a link to the weather in Vostok, Antarctica, the coldest place on Earth.
