The amount of ice flowing from the Antarctic glacier has doubled in the span of three decades, and scientists think it could undergo even more dramatic changes in the near future.
The icefields of Patagonia, located at the southern end of South America, are the largest masses of ice in the temperate Southern Hemisphere (approximately 55,000 square kilometers).
Where once two streams of ice merged in Greenland’s Jakobshavn Glacier, today there is division and a complex surface riddled with crevasses and melt ponds.
Ferrar Glacier begins at Taylor Dome and flows toward the Ross Sea. North of it, an unusual feature known as “Blood Falls” stains ice bright red in one of Antarctica’s rare dry valleys.
In August 2016, an iceberg heaved away from the Porcupine Glacier in northern British Columbia. It could be the biggest calving event in North America since satellite observations began.
