Climate models may underestimate future warming on tropical mountains

PROVIDENCE, R.I. [Brown University] — In few places are the effects of climate change more pronounced than on tropical peaks like Mount Kilimanjaro and Mount Kenya, where centuries-old glaciers have all but melted completely away. Now, new research suggests that future warming on these peaks could be even greater than climate models currently predict.

Researchers led by a Brown University geologist reconstructed temperatures over the past 25,000 years on Mount Kenya, Africa’s second-highest peak after Kilimanjaro. The work shows that as ...

Nadia Prupis – Global Sea Ice Hits Lowest Levels ‘Probably in Millenia’

Global sea ice levels are at their lowest in recorded history, according to new statistics from the U.S. National Snow & Ice Data Center.

In the Arctic, the loss is due to climate change and extreme weather events that are likely influenced by global warming, while the changes in the Antarctic may be attributed to natural variability, the center said.

But as a result of the declines in both regions, the total loss of ice is likely at the lowest it’s ...

Mary Hoff – 15 Most Surprising Trends for 2017

What should we be thinking about when we think about the future of biodiversity, conservation and the environment? An international team of experts in horizon scanning, science communication and conservation recently asked that question as participants in the eighth annual Horizon Scan of Emerging Issues for Global Conservation and Biological Diversity. The answers they came up, just published in the scientific journal Trends in Ecology & Evolution and summarized below, portend both risks and opportunities for species ...

Andrea Germanos – Sounding ‘Death Knell’ for Reef, Massive Australian Coal Project Heads Towards Completion

Indian energy giant Adani on Monday achieved a “key milestone” in completing its massive and controversial Carmichael coal mine project in Australia—a project, according to a marine conservation group, “that will super charge climate change and sound the death knell for our Reef.”

The achievement comes thanks to Queensland’s Coordinator-General giving “the latest, and final, secondary approval” for a permanent rail line and a temporary construction camp.

With those in place, the Australian Associated Press reports, “Construction on ...

Nika Knight – ‘The Coral Was Cooked’: 2016 Deadliest Year on Record for Great Barrier Reef

The Great Barrier Reef suffered through the worst coral die-off in recorded history this year, scientists found, with unusually warm ocean water and record-setting bleaching eventskilling a stunning 90 percent of all coral in the worst-hit area.

Those were the conclusions of a study published Monday by the ARC Centre of Excellence for Coral Reef Studies.

“One of the worst-hit areas is around Lizard Island in Far North Queensland, where around 90 percent of the coral has died,” reports the BBC. ...

BILL MCKIBBEN – Time to Declare a War (Literally) on Climate Change

In the North this summer, a devastating offensive is underway. Enemy forces have seized huge swaths of territory; with each passing week, another 22,000 square miles of Arctic ice disappears. Experts dispatched to the battlefield in July saw little cause for hope, especially since this siege is one of the oldest fronts in the war. “In 30 years, the area has shrunk approximately by half,” said a scientist who examined the onslaught. “There doesn’t seem anything able ...

BRYAN NELSON – Humpback whales around the globe are mysteriously rescuing animals from orcas

Humans might not be the only creatures that care about the welfare of other animals. Scientists are beginning to recognize a pattern in humpback whale behavior around the world, a seemingly intentional effort to rescue animals that are being hunted by killer whales.

Marine ecologist Robert Pitman observed a particularly dramatic example of this behavior back in 2009, while observing a pod of killer whales hunting a Weddell seal trapped on an ice floe off Antarctica. The orcas were able to ...

First Mammal Goes Extinct Due to Human-Caused Climate Change

The Bramble Cay melomys—a rodent found only on Australia’s Great Barrier Reef—has been declared extinct, according to a new study from researchers at the Queensland’s Department of Environment and Heritage Protection and the University of Queensland.

Alarmingly, this could be the first mammal species wiped out due to human-induced climate change.

The researchers came to the conclusion after failing to find a single specimen of the melomys, also called the mosaic-tailed rat, from its only known habitat.

“A thorough survey effort involving 900 ...

Breaking: Big Food Giant Guilty of Money Laundering in GMO Labeling Stunt

A landmark case about the dirty-money and politics that go into keeping Big Food and Big Biotech afloat was just decided.

Judge Anne Hirsch awarded a summary judgment in a suit brought against the Grocery Manufacturer’s Association by Attorney General Bob Ferguson, finding the GMA guilty of a money laundering scheme that shielded members’ identities as they helped to defeat Washington’s 2013 GMO labeling ballot initiative, I-522, with their donations.

The GMA includes big names in the food industry like Monsanto, Nestle, ...

For many species, noise pollution can be deadly

Some reef-dwelling fish are twice as likely to get gobbled up by predators in the presence of a noisy motorboat, according to a study released Friday.

The research, published in Nature Communications, adds to a growing body of evidence that noise pollution — on land and in the water — is a serious menace for wildlife.

Many mammals, birds and other animals use sound to locate food, avoid predators, navigate their environment, and even select a mate.

But all ...
