Arctic Snow Cover Rapidly Retreating

August 17, 2014

Scientists have known for a while that Arctic snow cover and sea ice are retreating, but the magnitude of problem wasn't so clear. New long-term measurements have solved that problem, and the news isn't good.

In the last 50 years, snow cover over Arctic sea ice has thinned rapidly, according to a study by NASA and the University of Washington.

The report shows that snow cover has thinned by half in some parts of the Arctic Circle, which can cause problems for the ice below.

Researchers are uncertain what effects melting snow cover will have on the environment, but they predict that less snow cover could cause the ice to melt quicker in spring.

The retreating sea ice could also have an impact on animal habitats.

A Mostly Mild and Dry January for U.S., Punctuated by Big Storms

The strong El Niño event dubbed “Godzilla” by one oceanographer behaved more like a hero than a monster in January, at least when it came to conditions across the United States. Mild and dry weather prevailed over much of the nation, and where it was wet or snowy, the moisture was generally well predicted and widely appreciated, apart from a titanic Northeast snowstorm.

California: What a Difference a Month Makes

One month ago I posted a blog about the precipitation deficits that were endemic in California at that time (December 9, 2015) but just prior to the beginning of a series of storms that rolled in. As was expected, the storm door opened and remains open. Here is where California now stands as of January 9th, 2016 precipitation-wise. Looking a lot better!

Why the Arrest of a Science-Loving 14-year-old Matters

By now, many of you have heard or read about the arrest of Ahmed Mohamed, a 14-year-old high school student from Irving, Texas. Ahmed was arrested because school officials called the police after he showed one of his teachers his homemade clock. Mistaken for a bomb, Ahmed was taken into custody, interrogated, shamed, suspended (still on suspension today, Wednesday), and reprimanded. All of this after it has been found that the "device" he brought to school was indeed, a homemade clock.

What the 5th IPCC Assessment Doesn't Include

By Angela Fritz
September 27, 2013

Melting permafrost has the potential to release an additional 1.5 trillion tons of carbon into the atmosphere, and could increase our global average temperature by 1.5°F in addition to our day-to-day human emissions. However, this effect is not included in the IPCC report issued Friday morning, which means the estimates of how Earth's climate will change are likely on the conservative side.
