The Aral Sea has made Central Asia significantly dustier, according to study

The drying up of the Aral Sea has made Central Asia 7% dustier in the last 30 years. Between 1984 and 2015, dust emissions from the growing desert almost doubled from 14 to 27 million tons. This is the result of a study by ...

The limits of ice: What a 19th-century expedition trapped in sea ice for a year tells us about Antarctica's future

In 1897, the former whaling ship RV Belgica left Antwerp in Belgium and set sail due south. It was the first voyage of what would become known as the Heroic Age of Antarctic exploration. It did not go to plan.
