Sentences with phrase «melt during the summer season»

In a new study, Box and a team of researchers describe the decline in ice sheet reflectivity and the reasons behind it, noting that if current trends continue, the area of ice that melts during the summer season is likely to expand to cover all of Greenland for the first time in the observational record, rather than just the lower elevations at the edges of the continent, as is the case today.

Many rivers draining glaciated regions, particularly in the Hindu Kush - Himalaya and the South - American Andes, are sustained by glacier melt during the summer season (Singh and Kumar, 1997; Mark and Seltzer, 2003; Singh, 2003; Barnett et al., 2005).

The reason: until the end of the melting season the fate of the ice is ultimately determined by the wind conditions and air and water temperatures during the summer months.

The lowest extent on record came during the remarkable summer melt season of 2012, fueled in part by summer storms that moved ice into warm waters.

What the scientists think happened was that the traditionally older, thicker ice around Greenland and the Canadian archipelago «just didn't melt away as much as it usually would» during the cooler summer conditions, «and it kind of just remained over the summer melt season,» Tilling said.

Increased surface melting, loss of ice shelves, and reduction of summer and autumn sea ice around the Antarctic and Greenland continents during the warmest interglacials would have a year - round effect on temperature, because the increased area of open water has its largest impact on surface air temperature in the cool seasons.
