Flooding in LaPlata

In early April 2013, severe flooding claimed more than 50 lives, and forced thousands from their homes in the Buenos Aires region, news sources said. Many of the casualties occurred in La Plata, situated about 60 kilometers (40 miles) southeast of Buenos Aires. Roughly 40 centimeters (16 inches) of rain fell on La Plata in a two-hour period April 2-3, Agence France-Presse reported.

Ice on the Caspian

The Caspian Sea isn’t really a sea but in fact a giant lake that spans roughly 1,000 kilometers (600 miles) from north to south. In the winter, ice often forms over the lake’s northernmost reaches, while the central and southern parts remain ice free. Temperatures are generally lower in the north, so you might guess that the ice owes its existence purely to the higher latitude. But the reality is more complex: From north to south, the Caspian Sea also exhibits differences in salinity and depth. Read more

Dust Storm in Libya

A dust storm blew out of Libya and across the Mediterranean Sea in late March 2013. Southwest of the coastal city of Banghazi (Benghazi), an especially thick dust plume spanned roughly 100 kilometers (60 miles), and the plume was thick enough to completely hide the ocean surface below. Read more
