Regelation Lets Glaciers Flow

Under the cold temperatures and immense pressures of a glacier, ice does not always behave in ways we’d expect. For example, cutting through ice using the pressure of a weighted wire does not break an ice block in two; as the wire passes through the ice, the melted water refreezes in its wake, leaving an intact block. Known as regelation, this process is one way that glaciers flow past obstacles in their path.

Although many experiments demonstrate regelation for ice with temperatures near freezing, the process occurs in colder ice, too. A new study combines data across a wide range of temperatures with a new physical model of regelation to show how the process changes with temperature. It seems that relatively small temperature changes drastically affect how much meltwater forms around the wire and how slowly the ice refreezes. (Image credit: S.

I am so excited to share the beautiful North American cover of #Melting the Ice Queen, coming March 16th, 2027! 😍

This epic conclusion to my Queens of Villainy trilogy features an ice queen’s marriage of convenience to a fiery high priestess, with "no feelings ever to be involved."

(Yeah, right. 😘 ❤️‍🔥 )

Their world will never be the same again!

Boy, it almost seems like a #GlobalConspiracy by #BigOil and #BigMineral... Keep warming temps so they can mine #Antarctica!

Antarctica hides huge caches of gold, silver, copper and iron. As the ice melts, countries may race to harvest them.

Melting ice, rebounding land, and rising seas will change what resources are available in Antarctica, a new analysis finds.

Blue Jewels and Gray Haze

Beginning in early spring, brilliant blue ponds form on Greenland’s ice sheets as meltwater gathers in indentations. This satellite image shows the ice east of Nordenskiöld Glacier, which is the tongue of ice projecting on the left side of the image. The center region of ice is darker, marked by soot, ash, and dirt left behind after previous ice layers have melted. These darker remains make the ice less reflective to sunlight; with less reflectivity, the ice absorbs more sunlight, melting faster. (Image credit: M. Garrison/NASA Earth Observatory)
