3. The Dangers of Glacial Lake Floods: Pioneering and Capitulation

During the past 70 years, Peruvian engineers virtually eliminated the risks posed by glacial lake floods. But climate change and a political blind eye are increasing the dangers once again.

Natural Resources:

1. Mystery of Green Icebergs May Soon Be Solved

Glaciologists report in a new study that they suspect iron oxides in rock dust from Antarctica’s mainland are giving some icebergs an unusual color.

Space & Planets:

1.Erupting Saltwater and the Bright Spots in Occator Crater, Ceres

Simulations show that pockets of brine that form from the addition of impact heat to the crust of Ceres could have erupted on the floor of Occator crater, explaining the presence of the bright spots.
