Climate Change Is Making It Hard for Bears to Hibernate Through the Winter

What was once a rare sight—a bear wandering outside its den before springtime—has become increasingly common, thanks to climate change. As The New York Times reports, warming temperatures are waking American black bears from hibernation earlier than ever, and in some cases, preventing them from settling down for the winter in the first place.

Hibernation is a vital part of the black bear's life cycle. When awake, a bear must consume at least 11 to 18 pounds of food per day to maintain a healthy body weight. Withdrawing for the winter allows it to survive the food scarcity that comes with the colder months.

But as climate change promotes certain extreme weather patterns in the western U.S., the region's black bear population has begun to act differently. Last year the Pine Nut Mountains in Nevada saw unusually high levels of snowfall, and the excess moisture produced an abundant pine nut crop. This past winter, snowfall in the area hit near-record lows, leaving the pine nuts exposed on the ground for a longer period. The prolonged access to food in the area meant some bears started hibernating later or just never got around to it.

Many of the bears that did eventually crawl into their dens were woken up ahead of schedule this year. According to a 2017 study, for every 1°C that minimum winter temperatures rise, bears hibernate six days fewer. In January 2018, temperatures in the Pine Nut Mountains reached 5.4°C above the 20th-century average for the region.

Some years bears emerge from hibernation during droughts, which are exacerbated by climate change, and food is hard to come by. When that's the case, bears may end up on private property, raiding people's trash cans and bird feeders and sometimes breaking into their homes. Fatal bear attacks on humans aren't common: The more likely scenario is that the so-called problem bear will be euthanized. Bear management groups will often try other strategies, like capture and release and aversive conditioning, before resorting to this option. Nonetheless, dozens of bears are euthanized by states each year.

Black bears aren't the only ursine species being forced to adapt to global warming. In the Arctic, polar bears are losing the sea ice they need to hunt marine mammals, and many of them are moving onto land in search of prey. Climate change is pushing both species of bears toward human-populated territory, which means conflicts between the bears and people will only increase from here.

15 Animal Names That Can Be Used As Verbs

People can go fishing, rabbit on incessantly, dog one another, and horse around. But because of their usefulness in completing burdensome work, horse has also been used in (originally naval) slang since the mid-19th century to mean “to work to the point of exhaustion”—or, in the words of the Oxford English Dictionary, “to drive or urge at work unfairly or tyrannically.” But horses aren’t the only animals whose names can be “verbed.” From turtles to tigers, you can drop any one of these 15 creatures into your everyday conversation.

1. Bulldog

No one is entirely sure why bulldogs are called bulldogs, with different theories pointing to everything from their bull-like stature to their bullish faces to the fact that they might once have been bred to bait bulls. Whatever the origin, the bulldog’s strength and its robust, resilient behavior means that you can use its name as a verb meaning “to attack roughly,” or “to wrestle to the ground.”

2. Tiger

If you tiger, then you walk to and fro, like a tiger pacing in a cage. If you tiger something, then you paint or mark it with contrasting stripes.

3. Spider

As well as being used simply to mean “to creep” or “to move like a spider,” if you ensnare or entrap something, or else cover it in a cobweb-like pattern, then you spider it.

4. Cat

Because the cathead is the horizontal beam at the bow of a ship that’s used to raise an anchor, the word cat has a number of nautical uses as a verb, including “to lift an anchor from the water,” “to secure an anchor,” and “to draw an anchor through the water.” But because shooting the cat was 19th century slang for being sick from drinking too much, you can also use cat to mean “to vomit.”

5. Vulture

Vultures’ grim feeding habits and their remarkable flying ability have given the word two meanings as a verb in English. Feel free to use it to mean “to eat voraciously” or “to tear at your food,” or else “to descend steadily through the air.”

6. Owl

Owling (as well as being a short-lived social media craze) was once the name given to the crime of smuggling sheep and wool from England to the continent—a crime so-called because the nefarious “owlers” carried out their crimes at night. That might not be the most useful of words these days of course, so feel free to also use owl to mean “to act wisely, despite not knowing anything.”

7. Shark

It’s easy to presume that the use of shark as a verb to mean “to act like a predator” (which is the same shark as in loanshark, incidentally) derives from the deadly sea creatures. In fact, it might be the opposite: Both meanings of the word shark date back to the late 16th century, but it’s possible that the verb shark is the older of the two. If so, it’s possible that it comes from the earlier word shirk (in the sense of using deceit or trickery to avoid work) or else a northeastern French word, cherquier, which was often used in a phrase that essentially meant “to sponge of others” or “to act as a parasite.” So how did sea-dwelling sharks come to be called sharks? It’s possible the deceitful sharks gave their name to the menacing creatures, or else the two could be completely unrelated—and, thanks to a sea battle off the Yucatan peninsula in 1569, shark could in fact be a Mayan word.

8. Monkey

As well as meaning “to play the fool” or “to behave playfully”—as in “monkeying around”—monkey, like ape, can also be used to mean “to mimic” or “to copy someone’s movements or actions.”

9. Turtle

If a boat “turns turtle,” then it capsizes and flips over, so that it looks like a turtle’s domed shell floating atop the water. Because of that, to turtle something is to turn it upside down.

10. Snail

For obvious reasons, snail has been used to mean “to move slowly” since the late 16th century, but because of the snail’s coiled shell, you can also use snail to mean “to draw or carve a spiral,” or “to roll into a spiral shape.”

11. Porcupine

When your hair stands on end, feel free to say that it porcupined.

12. Canary

Canary birds take their name from the Canary Islands, which, somewhat confusingly, take their name from canis, the Latin word for “dog.” But in the 16th and 17th centuries, the canary was also the name of an energetic dance inspired by a traditional dance performed by the natives of the Canary Islands. And because of that, you can also use the word canary as a verb meaning “to dance in a lively fashion.”

13. Earwig

Earwigs are so-called because they were once (thankfully erroneously) thought to crawl inside people’s ears as they slept. Through association with someone whispering clandestinely into someone’s ear, in the late 18th century eavesdroppers and people who seeked to secretly influence others became known as earwiggers—and so to earwig is to do precisely that.

14. Pig

Pig has been used to mean “to give birth” since as far back as the 15th century in English (a fairly uncomplimentary allusion to a pregnant sow delivering a litter of piglets). But slightly less depreciatively, the living habits of pigs mean that it can also be used to mean “to huddle together,” or else “to live or sleep in crowded or dirty conditions.”

15. Dingo

Because of their stereotypically sneaky behavior, to dingo on someone meant “to let down” or “to betray” them in 1930s Australian slang, while to dingo meant simply “to shirk” or “to back out of something at the last minute.”

This list first ran in 2016.

Photographer's Up-Close Images of Animal Eyes Will Have You Seeing Wildlife in a Whole New Way

Few people ever get close enough to a hippo, hyena, or crocodile to snap a photo of one, let alone get a detailed shot of their eyes. Yet that is exactly what theoretical physicist-turned-photographer Suren Manvelyan, of Armenia, has done. His macro photography series of animal eyes, spotted by My Modern Met, offers a rare look at the animal world, amplified.

Some of Manvelyan's eye photos—like that of the camel, which has three eyelids—look like strange landscapes on some distant, alien planet. The smallest details have been captured in his photos, from the kaleidoscopic irises of the chinchilla and chimpanzee to the shimmery edges of a raven's eye. If the photos weren't labeled, it might be difficult to tell what you were looking at.

"It is very beautiful and astounding," Manvelyan told Radio Free Europe/Radio Liberty. "The surface resembles the surface of other planets, with craters, rivers, and valleys. It looks like something from another world. Every time I photograph the eye, I feel myself traveling through the cosmos."

Manvelyan keeps his photography techniques secret, but he says he sometimes spends an hour with an animal just waiting to capture the right moment. To date, he has photographed both domestic animals (like a husky dog and Siamese cat) as well as exotic ones (including a variety of tropical birds and lizards). Check out some of his shots below, and visit his website to see more photos from this series.
