Update on berg A-81🧊
This #Landsat image from Jan. 25 shows the A-81 berg on the left and the new front of the Brunt Ice Shelf on the right.
According to a @NASAGoddard glaciologist, satellite images show the front has retreated 20 km since 1973. go.nasa.gov/1333

Lake Albert in southern Oregon is drying up due to years of water withdrawals and dry weather.
The lake is also becoming too salty to support the flies and brine shrimp that serve as a food source for migrating birds.

Shrinking Lake Abert
As the lake in southern Oregon dries up, the remaining water is becoming too salty to support key food sources for birds.go.nasa.gov
To understand why the lake is drying up, scientists analyzed two decades of @nasa’s Terra satellite data.
They found that between 2001 and 2021, fewer days of snow cover and higher surface temperatures led to more evaporation over Lake Albert. go.nasa.gov/3kPwsIE

In Antarctica, a long-watched rift in the Brunt Ice Shelf produced an iceberg about twice the size of New York City: Iceberg-A81. 🧊
The iceberg, with an area of 1550 square kilometers (about 600 square miles), was captured by @nasa’s Terra satellite.
