Reindeer threatened by global warming

In what is "traditionally the busiest time of year" for reindeer, US environmental scientists warn that global warming means, oddly enough, too much ice in the north. Rain falling in the arctic causes a layer of ice that hooved mammals like caribou, musk oxen and reindeer can't dig through to get to the lichen below, their main source of winter food.
Just one of the many unexpected results of the current climate changes.
