Nations agree to ban fishing in Arctic Ocean for at least 16 years

Science


Nine nations and the European Union have agreed to place the central Arctic Ocean off-limits to commercial fishers for at least the next 16 years. The pact will give scientists time to understand the region’s marine ecology and the potential impacts of climate change. Story here.

A FOOTNOTE: In the interests of fairness and accuracy, it should be pointed out that it was Eva Pip,
a long-time water expert at the University of Winnipeg, and a colleague who are on the record as first confirming BMAA in Lake Winnipeg, NOT the BC research team referenced in the CBC story.

Global response to malaria at crossroads - WHO report shows gains are levelling off

World Health Organization

After unprecedented global success in malaria control, progress has stalled, according to the World malaria report 2017.  There were an estimated 5 million more malaria cases in 2016 than in 2015. Malaria deaths stood at around 445 000, a similar number to the previous year.

“In recent years, we have made major gains in the fight against malaria,” said Dr Tedros Adhanom Ghebreyesus, Director-General of WHO. “We are now at a turning point. Without urgent action, we risk going backwards, and missing the global malaria targets for 2020 and beyond.”

The WHO Global Technical Strategy for Malaria[ii] calls for reductions of at least 40% in malaria case incidence and mortality rates by the year 2020. According to WHO’s latest malaria report, the world is not on track to reach these critical milestones.

A major problem is insufficient funding at both domestic and international levels,  resulting in major gaps in coverage of insecticide-treated nets, medicines, and other life-saving tools.

Proposed fossil fuel development threatens yet another caribou herd - by Larry Powell.

According to the magazine Science, US politicians may be about to put the continent’s biggest and healthiest caribou herd at risk. That’s because a US Senate committee has just voted to allow drilling for oil in Alaska’s Arctic National Wildlife Refuge. The coastal plain region of the sprawling refuge happens to be the calving grounds for the Porcupine caribou herd.

Republicans supporting drilling say its footprint will be small. Environmental groups disagree, saying roads and pipelines will dissect the animals' habitat. 

A Canadian wildlife ecologist quoted in the story, Chris Johnson of the University of Northern BC (Prince George), says the consensus that industrial activity disturbs the animals is “pretty strong.” It has already been observed that caribou stay away from industrial activity, including diamond mines in Canada and will even move their calving grounds, as a result.

It is estimated that the Porcupine herd may consist of as many as 200 thousand animals.

US Republicans have been trying to open up the refuge to drilling for decades.

Yet another of Earth's creatures faces extinction. - by Larry Powell

It’s not looking good for the vaquita.

The vaquita are porpoises which measure only about 1.5 meters, fully grown. They’re among the smallest of the cetaceans, an order of marine mammals which includes porpoises, dolphins and whales. Their numbers have now dwindled to fewer than 30 in Mexico’s Gulf of California, where they live. 

The National Oceanic and Atmospheric Administration reports vaquita numbers have declined an astonishing 92% since 1997. Gill net fishing is the main culprit. The vaquita have become “collateral damage” as poachers target a fish whose swim bladder fetches $20 thousand dollars per kilogram for use in Chinese medicine.

Mexico has imposed a permanent ban on the taking of vaquita. But authorities have been unable to enforce the law sufficiently to make a difference.

Now, the magazine, Science is reporting, an eleventh-hour bid by a team of conservationists, to bring them back from the brink, has been a heartbreaking failure.

A rescue team has been trying for some two years now to capture enough live animals to breed them in captivity, so their numbers can recover. But the vaquita have proven so sensitive to the stress of capture, two females have now died. And the rescuers have decided it's just not worth risking the death of any more. So the effort has been called off with no plans for another.

The rescuers do not regret having tried. They’re just sorry they hadn’t started sooner.

So where does this leave these vulnerable, intelligent, innocent creatures? 
According to the author of the Science article - in “extreme peril.”

Worldwide increase in methane bubbles due to climate change

Science Daily
Due to climate change, more and more methane is bubbling up from lakes, ponds, rivers and wetlands throughout the world. The release of methane -- a potent greenhouse gas -- leads to a further increase in temperature, thus creating a positive feedback loop (also known as a 'vicious circle'). Story here.
