canary in the coal mine – gray wolves


Gray wolves could emerge as a “canary in the coal mine” of global warming by suggesting how climate change will affect species around the world, researchers say.

“We’re not so much looking at wolves as a predator but as an indicator,” says environmental scientist Christopher Wilmers of the University of California-Berkeley. Shorter winters without wolves mean about 66% fewer elk deaths every April, which threatens starvation for scavengers.

With wolves preying on elk, however, the drop in carrion is only about 11%, a much less dire situation.

“Because gray wolves are so intensively studied, they may give us very good data on the effects of climate change,” says ecologist Mike Phillips, executive director of the Turner Endangered Species Fund in Bozeman, Mont. “More specialized species, such as snowshoe hares, could show such effects even sooner,” he says, “but they receive less study.”

canary in the coalmine – an octopus in the garage!

Octopus in the parking garage is climate change’s canary in the coal mine.

Photos of an octopus splayed out in a flooded Miami Beach parking garage have been floating around the internet all week, prompting some skeptics to call “bogus” on both the discovery of the eight-legged creature out of its element and the force blamed for its appearance — climate change.

Both appear to be all too real. University of Miami associate biology professor Kathleen Sullivan Sealey examined the photos and identified the octopus as likely one of two species common in South Florida waters.

And she said Miami Beach residents ought to get used to seeing strange new creatures making sporadic appearances as rising sea levels push ocean waters deeper and more frequently onto land, along with some of the creatures that live in them.

Canary in the coal mine – Mount Wheeler

As the climate changes, disappearing snow and ice on Wheeler Peak — Nevada’s second-highest mountain — raise concerns about the future of water in the state, for which the glacier plays an integral role.

Climate change is expected to hit alpine ecosystems like Mount Wheeler’s hardest, said Steven Mietz, superintendent of Great Basin National Park.

“The region could be a baseline for measuring how nature reacts to global warming. The glacier is a canary in a coal mine,” he said.

Canary in the coal mine – Florida Keys

“We are feeling some of the most severe impacts of climate change first, and we have no escape route,” says Alison Higgins, President of Florida Keys Green Living and Energy Education and staff of The Nature Conservancy, thinking about the limitations to adaptation in the Keys.

“We’re the canary in the coal mine for climate change impacts in the U.S…We want to be seen as an example of why it’s important for other local governments to work hard on [climate] mitigation [to reduce carbon emissions.] Because that’s going to help us, and themselves.”

Canary in the coal mine – shrimp

Shrimp like canaries in coal mine, indicating health of stocks, water temperature. Peter Koeller, a Canadian fisheries scientist, said the findings shed light on the complex mating habits of the Pandalus borealis, the shrimp species that makes up one of the world’s largest fisheries and sustains an industry worth $500 million a year in the North Atlantic.

“Shrimp are very sensitive to changes in environmental conditions, be they global warming-driven or otherwise,” Koeller said from the Bedford Institute of Oceanography in Dartmouth, N.S., about the research to be published Friday in the journal Science.

Canary in the coal mine – Maldives

Maldives May Be Canary In The Coal Mine. Alas, the high point in this entire nation of 1,200 islands is only 8 feet above sea level. So people here worry that eventually the entire nation may have to move, making the Maldives perhaps the first country in the world to be destroyed by global warming. (Tuvalu and Kiribati, both small Pacific island nations, are other contenders for the title of the first modern nation to be drowned).

Canary in the coal mine – estuaries

When it comes to climate change impacts, estuaries are the proverbial canaries in the coal mine. These unique habitats, which are also home to 22 of the world’s 32 largest cities and are essential hubs for global commerce, face not just the threat posed by rising sea levels, but also a complex nexus of increasing storm risks, droughts, water and air pollution and marine dead zones.

Canary in the coal mine – walrus

Huge Walrus Haul-Out Signals Latest ‘Canary in the Coalmine’ for Climate Change in the Arctic.

Margaret Williams, managing director of the World Wildlife Fund’s Arctic program told the Associated Press, “The walruses are telling us what the polar bears have told us and what many indigenous people have told us in the high Arctic, and that is that the Arctic environment is changing extremely rapidly and it is time for the rest of the world to take notice and also to take action to address the root causes of climate change.”

Canary in the coal mine – oysters

A company near San Diego raises oysters. Last year, Dennis Peterson says they could only get a quarter of the young oysters, or seed, they need from hatcheries in the Pacific Northwest. Dennis Peterson worries about what that means for his oysters.

“When it comes to climate change,” he says, “the oyster in the ocean is like a canary in a coal mine.”

Canary in the coal mine – monarch butterfly

The poster child for conservation is at risk of being at risk. Environmental groups across the country are stepping up efforts to increase the population of monarch butterflies as the insects face being designated as a species at risk.

“They’re currently an international species of concern. The monarch butterfly is like the canary in the coal mine of climate change and conservation,” said Maxim Larrivée, the University of Ottawa professor who developed ebutterfly.ca, an online database of butterfly observation.

Canary in the coal mine – frog

Thus a climate canary would be an animal that is susceptible to the impacts of climate change. In that sense, frogs and other amphibians could be considered the “Canaries of global warming”.

Canary in the coal mine – finch

When it comes to global warming, the canary in the coal mine isn’t a canary at all. It’s a purple finch.

An Audubon Society study released Tuesday found that more than half of 305 birds species in North America, a hodgepodge that includes robins, gulls, chickadees and owls, are spending the winter about 35 miles farther north than they did 40 years ago.

Canary in the coal mine – Alaska

At a Senate hearing on Thursday, Sen. Bernie Sanders called Alaska the “canary in the coal mine” on climate change and cited threats to Native American communities from rising seas as a result of global warming.

The village of Newtok, Alaska, near the Arctic Circle, may be underwater by 2017, according to the U.S. Army Corps of Engineers, Sanders noted. More than 180 other native Alaskan villages also are at risk because of climate change, Sanders added.

Canary in the coal mine – Napa Valley

Is Napa Valley the canary in the coal mine? Climate change, the bad, the good and the unknown…

There is little consideration for the potential impact of global warming on all forms of agriculture and human and animal activity – were this apocalypse to come true, one could argue that world hunger, deforestation, coastal flooding and other horrific environmental changes would dominate the world’s agenda and no one would care about where the best Cabernet Sauvignon is produced.

Canary in the coal mine – cherry blossoms

DC’s Cherry Blossoms as Climate Change Canary…As a native of the Washington area, the Cherry Blossoms are perhaps the quintessential universal symbol of nature’s beauty. In short, a November 11 published scientific study from University of Washington suggests that Washington, D.C., will have to move the Cherry Blossom up by nearly a month by 2050 or risk having blossom-less trees for the parade.
