The first ever worldwide census analysis of caribou/reindeer numbers reveals a nearly 60 percent decline worldwide in the last three decades.

This dramatic decline across the circumpolar world is a result of a bad intersection between global warming and industrial development, according to the data published in Global Change Biology.

Global warming is affecting the herds in three of four season. The spring green-up in the Arctic now arrives earlier—before the migrating herds arrive, depriving mothers and calves of quality feeding. Warmer summers cause more intense insect blooms that harass the herds and affect their ability to feed. Winters produce more freezing rains that ice over and make inaccessible the lichens the animals feed on during the dark months. I wrote about a particularly bad freezing rain event a year ago.

Meanwhile industrial development in the boreal forest has driven the decline of many herds.

The analysis raises serious concerns not only for the animals but also for people in northern latitudes who depend on caribou/reindeer for their livelihood.

For all of us, really.

A BETTER WAY TO DO THIS?

We have an ambitious $350,000 online fundraising goal this month and we can't afford to come up short. But when a reader recently asked how being a nonprofit makes Mother Jones different from other news organizations, we realized we needed to lay this out better: Because "in absolutely every way" is essentially the answer.

So we tried to explain why your year-end donations are so essential, and we'd like your help refining our pitch about what make Mother Jones valuable and worth reading to you.

We'd also like your support of our journalism with a year-end donation if you can right now—all online gifts will be doubled until we hit our $350,000 goal thanks to an incredibly generous donor's matching gift pledge.
