Small ice caps in the Arctic are very sensitive indicators of the effects of climate change
"I can't say I was terribly surprised because we knew they were going, but it has happened really fast," Mark Serreze, director of the National Snow and Ice Data Center, told CNN. Serreze co-authored aThe two ice caps were located on the Hazen Plateau of northeastern Ellesmere Island in Nunavut. Data from 1959 suggests the area of the larger cap was 3 square miles and the smaller one 1.1 square miles, declining ever since.
Hotter heat waves and cold waves that are not as cold as they were in the past are contributing factors.The disappearance of the St. Patrick's Bay ice caps is"an exclamation point of what's happening in the Arctic," Serreze added. Neumann, who studies the Earth's ice cover through satellites, told CNN that the melting of Northern Hemisphere glaciers has been an ongoing process that has worsened in recent years.
"We should care because even though this is a little glacier somewhere in Arctic Canada, collectively all of these glaciers contribute to sea level rise," he told CNN.
