The effects of global warming in the Arctic are so severe that the region is shifting to a different climate, one characterized less by ice and snow and more by open water and rain, scientists said Monday.

“Already, they said, sea ice in the Arctic has declined so much that even an extremely cold year would not result in as much ice as was typical decades ago. Two other characteristics of the region’s climate, seasonal air temperatures and the number of days of rain instead of snow, are shifting in the same way, the researchers said.”

Ice loss on Africa’s highest peak prompts star climber Will Gadd to reconsider his sport…

“Gadd, the first person to climb a frozen Niagara Falls, had hoped to scale the remaining ice atop Africa’s highest peak [Mount Kilimanjaro] with climbing partner Sarah Hueniken in February. But when they got there, they discovered that the extremely challenging Messner route they wanted to attempt – scaled only once since the 1980s – had lost so much ice it was impossible to ice-climb.”
