About half the recent record loss of Arctic sea ice can be blamed on global warming caused by human activity, according to a new study by scientists from the nation's leading climate research center.
he peer-reviewed study, funded by the National Science Foundation, is the first to attribute a specific proportion of the ice melt to greenhouse gases and particulates from pollution.
The study used supercomputers named Bluefire and Franklin and one of the world's most sophisticated climate models to reach its conclusions, said lead author Jennifer Kay, a staff scientist at the National Center for Atmospheric Research. The paper was published last week in the scientific journal Geophysical Research Letters. (more)
