What’s up with the Antarctic weather?
On Feb. 6, a record high temperature of 65 degrees was recorded at a research base located at the most northern tip of Antarctica. That beats the previous record of 63.5 set in March 2015.
Then on Feb. 9, the temperature on Seymour Island in the Antarctic Peninsula reached 69.5, setting a new record. This is the warmest temperature measured on the world’s coldest continent. Continue reading
What is snow sparkle?
Saturday was a bright, sunny day, and if you were walking by an undisturbed field of snow, the snow may have appeared to sparkle.

As we have reported several times over the years, the evidence is clear that over the entire Northern Hemisphere winter temperatures have been systematically warming over the past 70 years.
We base that conclusion on measuring the extent of air with a temperature of 23 or colder at the 850 millibar level, which is located about 1 mile above sea level. Such a measure can equally be made in the autumn months. Continue reading
