From sand and gravel to rock salt and magnesium chloride, the people who maintain our roads are constantly searching for the most most innovative ways to keep our road clear of snow and ice. Our science guy Steve Spangler looks at the science of de-icing with a cool experiment you can try at home. Continue reading
Throughout Earth’s history, climate has varied greatly. For hundreds of millions of years, the planet had no polar ice caps. Without this ice, the sea level was 70 meters higher. At the other extreme, about 700 million years ago, Earth became almost entirely covered in ice, during an event known as “Snowball Earth.” Continue reading
Where do glaciers and icebergs get their beautiful blue color? This unique blue might be nature’s most brilliant, and the color arises in a very special way thanks to some surprising interactions between light and water molecules. Who knew physics could be so breathtaking? Continue reading
This rare footage has gone on record as the largest glacier calving event ever captured on film, by the 2016 Guiness Book of World Records.
On May 28, 2008, Adam LeWinter and Director Jeff Orlowski filmed a historic breakup at the Ilulissat Glacier in Western Greenland. The calving event lasted for 75 minutes and the glacier retreated a full mile across a calving face three miles wide. The height of the ice is about 3,000 feet, 300-400 feet above water and the rest below water.

Chasing Ice won the award for Excellence in Cinematography at the 2012 Sundance Film Festival and a 2013 Emmy Award for Outstanding Nature Programming. It has won over 40 awards at festivals worldwide, and was also nominated for an Academy Award for Best Original Song, “Before My Time” by J. Ralph featuring Scarlett Johansson and Joshua Bell.
A new study may help mankind understand the gravity of climate change.
West Antarctica has lost so much ice between 2009 and 2012 that the gravity field over the region dipped, according to an announcement Friday from the European Space Agency (ESA). The conclusion is based on high-resolution measurements from satellites that map Earth’s gravity.
The gravitational fluctuation over the Antarctic Peninsula is small, but it’s further evidence that melting ice is fundamentally changing parts of the planet. Continue reading
