"The glaciers of the Andes Mountains have retreated at an unprecedented rate in the past three decades, with more ice lost than at any other time in the last 400 years."
"Precipitation in the region has not changed, the researchers found, but temperatures have risen nearly 0.2 degrees Fahrenheit (0.1 degrees Celsius) per decade over the last 70 years."
"Antarctica Glacier's Retreat 'Unprecedented'"
"In the past 20 years, Pine Island Glacier's grounding line, the location where the glacier leaves bedrock and meets the ocean, has retreated at a rate of more than 1 kilometer a year. The glacier itself has thinned at a rate of 5 feet (1.5 meters) a year since the 1990s, and its flow rate has accelerated by 30 percent in the past 10 years."
