Bears Starving in Canada

Grizzlies in Canada are starving as the salmon population withers amid climate change. Excruciatingly thin grizzly bears in Canada are fresh evidence of the dire consequences of climate change and vanishing food sources for wildlife. Salmon, a key food source for grizzlies, is at an all-time low, affected by climate change. Fisherman say the salmon population is the smallest they’ve seen in 50 years.

Bird Populations in Mojave Desert Collapse

Bird populations in the Mojave Desert have collapsed over the last century, and now scientists say they know why: The animals’ bodies can’t cope with the hotter and drier weather brought on by global warming.

The discovery, described this week in the Proceedings of the National Academy of Sciences, draws upon historical records and high-tech virtual bird modeling to explain how climate change has caused such drastic population losses — and how it will likely cause even deeper losses in the future.

As climate change and habitat destruction due to human activity continue across the globe, many species have found themselves in decline or under threat. A recent study in the journal Science, for instance, found that there are nearly 3 billion fewer birds in North America today than there were in 1970.
