On the whole, the model projects a contraction within current ranges during both seasons, with a loss of 58 percent of current summer range and 44 percent of current winter range. (climate.audubon.org)
However, this comes at the cost of significant loss of current winter climate space. (climate.audubon.org)
Audubon's climate model projects a 64 percent loss of current winter range by 2080. (climate.audubon.org)
