Warming
Don't be fooled by Fox News "experts" claiming that the Arctic is not warming. A recent article in Science, summarized by BBC News, reports that this last half century, especially the last 10 years, have been the warmest in the last 2000 years of the Arctic's history.

The extinction crisis is continuing to steam ahead at full speed, as documented by scientists with the International Union for the Conservation of Nature, who found that at least 25% of mammals are headed towards extinction. It doesn't help that extinctions happen in clusters, meaning that if one species from a family goes extinct, there's a domino effect on the rest of that family.
