Obama to create the largest protected place on the planet, off Hawaii

The Papahanaumokuakea Marine National Monument is set to become the largest ecological preserve in the world.
A graphic from The Pew Charitable Trusts puts that size in perspective — the area will be more than 3.5 times the size of California, 10 times the size of Iowa and 105 times the size of Connecticut.

President Obama on Friday created the largest ecologically protected area on the planet when he expanded a national marine monument in his native Hawaii to encompass more than half a million square miles.
The president more than quadrupled the size of the Papahanaumokuakea (pronounced “Papa-ha-now-moh-koo-ah-kay-ah”) Marine National Monument to 582,578 square miles of land and sea in the Northwestern Hawaiian Islands.
President George W.
Bush established the monument a decade ago, but Obama’s action Friday underscores the high priority he has placed on issues of conservation and climate change in his second term.
The president has now used his executive authority under the 1906 Antiquities Act to protect more than 548 million acres of federal land and water, more than double the set-asides of any of his predecessors.



Many scientists, environmentalists and Native Hawaiians have argued for more stringent protections for the biologically rich region, given important deep-water discoveries in the area and the dual threats of climate change and sea-bed mining.
“The oceans are the untold story when it comes to climate change, and we have to feel a sense of urgency when it comes to protecting the ocean that sustains us,” said Sen.
Brian Schatz (D-Hawaii), who helped broker a compromise with groups including Native Hawaiians and day-boat fishermen.

 The expansion of Papahānaumokuākea Marine National Monument, surrounding the Northwestern Hawaiian Islands, is one of the largest conservation actions in history.
The monument is now the largest protected area in the world—almost four times as large as California—measuring a total of 582,578 square miles.
Papahānaumokuākea also happens to be one of the most biologically and culturally significant places on the planet.
The expansion not only creates a safe zone for the replenishment of tuna stocks and promotes biodiversity—it gives Native Hawaiians a greater voice in managing this precious resource.

In his official proclamation, Obama declared, “It is in the public interest to preserve the marine environment.”
All commercial extraction activities, including fishing and future deep-sea mining, will be prohibited in the expanded monument area.
However, recreational fishing, removal of resources for traditional Hawaiian cultural purposes and scientific research will be allowed with a federal permit.
Obama will highlight his action in an address Wednesday to the Pacific Islands Conference of Leaders and the IUCN World Conservation Congress in Honolulu, and will travel the following day to Midway Atoll, which is located within the current monument.
The president has unilaterally established more than two dozen national monuments, most of them in his second term.
White House press secretary Josh Earnest said Obama “would be happy to sign into law a piece of legislation that would have protected these waters, but we haven’t seen that kind of legislative activity in this Congress, and it means the president has had to make more effective use of his executive authority.”

Longline fishermen lobbied against any new protections, arguing that their industry rejects damaging practices such as trawling and needs flexibility to sustain an annual catch valued at more than $100 million.
“We move all over the ocean, in the way the fish move,” said Jim Cook, co-owner of POP Fishing and Marine, a Hono­lulu store, adding that the new restrictions mean 60 percent of federal waters off Hawaii are now closed to fishing.

With Friday’s action, seven presidents — starting with Theodore Roosevelt in 1909 — have taken steps to safeguard parts of the archipelago, which is one of the most biologically diverse areas in the world.
It is the planet’s largest seabird gathering site, with more than 14 million birds from 22 species, and is home to nearly all Laysan albatrosses and the remaining endangered Hawaiian monk seals.


Recent research expeditions have unearthed extraordinary features beyond the existing monument boundaries, such as the world’s oldest living animal — a black coral estimated to be 4,500 years old — and six massive seamounts, one of which is nearly 14,000 feet high and teeming with life.
This area also includes the wreckage of the USS Yorktown, which sank during the Battle of Midway in 1942 and has not been visited since it was discovered there in 1998.

Daniel Wagner, a researcher at the National Oceanic and Atmospheric Administration who served as the scientific lead for the agency’s deep-water expeditions in the region a year ago and again in February, said every one of the 50 biological samples that remotely operated vehicles recovered were either new species or “not known to live in the area.”
“We’re seeing a lot of life, a lot of new life and a lot of very old life,” he said.
“Things have not been disturbed for a very long time.”
Wagner said he is particularly concerned about future underwater mineral extraction, given the rich deposits of manganese, nickel, zinc, cobalt and titanium in the region.
“If they’re not protected, they’re going to be exposed to mining,” he said.

Matt Rand, director of the Pew Charitable Trusts’ Global Ocean Legacy program, said that intact ecosystems such as these “offer a glimpse of what our planet was like before the impacts of human activity, and it is critical that we preserve places in this way, both as a window to the past and for future generations.”
Schatz suggested a change to the proposal that carved out areas where day-boat fishermen in Kauai and Niihau can continue operating.
His suggestion won the support of influential state officials such as Democratic state Sen.
Ron Kouchi.
Kouchi said in an interview that he could back Obama’s expansion as long as it is the last one.
“One of the questions the fishermen are asking is, ‘When will it stop?’ ” he said.

Federal officials estimate that 5 percent of current commercial fishing efforts will be displaced.
Longline operators already catch about half their fish in international waters, and they reached their annual catch limit for big-eye tuna in early August.
However, Sean Martin, president of the Hawaii Longline Association, said the industry’s fleet of 145 boats could not match the lobbying power of well-financed environmental groups such as Pew.
“We’re obviously going up against environmental organizations that have billions of dollars,” Martin said. “For somebody to feel good, we’re going to force U.S.
fishermen out of waters.”

Republicans have accused Obama of abusing his authority under the Antiquities Act, which says any protections must “be confined to the smallest area compatible with proper care and management of the objects to be protected.”
But Richard Pyle, a researcher at Hawaii’s Bishop Museum, said he and other scientists have concluded that the ecological interconnectedess of the region — including the fish larvae that are dispersed on currents, and the sharks and other pelagic fish that travel vast distances — extends beyond federal waters.
“The minimum space necessary for protection, it’s more about 350 to 380 miles, but of course we don’t have the jurisdiction for doing so,” Pyle said.
Some Native Hawaiian activists, moreover, lobbied for greater protection so they could continue to observe traditional voyaging practices in which they navigate without instruments.

The state Department of Land and Natural Resources and the Office of Hawaiian Affairs will serve as trustees in managing the monument.
William Aila, a former state official and Hawaiian activist, said Thursday that the president’s move will preserve “a cultural seascape, with the history of the Polynesians who migrated up to Hawaii.”
He recalled that when he journeyed to Mokumanamana, or Necker Island, in 2009, “you could feel the presence of your ancestors,” not just in the earth but in “the symphony of birds, all night and all day long.”
Asked what he thought of the monument expansion, Aila switched to Hawaiian.
“Olu olu,” he said.
“In English, that’s ‘very pleasant.’ ”

Into the sea

Making the connection between how we care for our yard and the health of our local waterways 

From Surfrider

Most people have no idea of the connection between how they manage their lawn and gardens at home and the health of our local waterways and beaches.

From unnecessarily treating our garden and lawns with chemical fertilizers and pesticides to applying too much water, we’re killing all the beneficial biology in our soils that support beautiful and healthy plants, and it’s creating polluted runoff. Landscaping chemicals don’t stay where they are applied, but instead can leach into groundwater or be washed away by runoff when it rains or when misdirected irrigation runs off our properties. The resulting storm water and urban runoff pollutes local waterways and harms coastal ecosystems by causing harmful algal blooms and killing fish and other aquatic animals. Water affected by runoff makes it dangerous to swim and play in.

Ocean Friendly Gardens act like a sponge in your landscape. These gardens are shaped in a natural way to capture rain and runoff, contain native, climate appropriate plants and healthy, living soil which soaks up, stores and filters out pollutants from stormwater and road runoff. They have the added bonus of providing native habitat for bees, birds and butterflies. And it’s an important tool in addressing climate change as healthy plants and soil work in combination to capture and store carbon from the atmosphere. In the most basic terms, Ocean Friendly Gardens can conserve water, help clean up local waterways, and be beautiful and affordable too.
Want to make your backyard more ocean-friendly? Here are some easy ways to conserve water and prevent polluted runoff from hitting the ocean:
Get dirty! Stop using chemical fertilizers and pesticides and pull weeds by hand instead.
Mulch, mulch, mulch. Apply organic compost to your yard and garden and cover it with mulch to build healthy, living soil that acts like a sponge to hold onto rain for your plants’ use during dry months. Soil microbes, which are like probiotics, help the soil’s ability to absorb nutrients and resist drought, disease and pests and aid in cleaning up pollution and capturing carbon that plants absorb from the atmosphere.
Compost. Make your own soil amendments by composting your yard and kitchen scraps in a compost or worm bin.
Go native! Plant native plants and grasses that don’t need supplemental irrigation when they are fully-grown. You’ll also be providing food and habitat for butterflies, birds and bees.
Shape your garden to slow down and soak up rainwater. Leave a natural buffer or slightly raised border around the edge of your yard to prevent runoff from leaving your property and polluting local waterways.
Barrel on! Install a rain barrel to store rainwater for future watering needs, and direct the overflow into the landscape and not onto the driveway and out to a storm drain. If rain barrels are not an option, direct gutters to the landscape. This reduces flooding and keeps polluted runoff from reaching the ocean.
Mind the gap. Make your walkways and driveways permeable by cutting gaps in them or make sure they are pitched to drain into your yard.

Healthy beaches start upstream with clean rivers, lakes and streams. Whether you live inland or by the coast, we can all do our part to protect local waterways and our ocean from being polluted.

Man of Aran

Man of Aran is a 1934 British fictional documentary (ethnofiction) film directed by Robert J. Flaherty about life on the Aran Islands off the western coast of Ireland.
It portrays characters living in premodern conditions, documenting their daily routines such as fishing off high cliffs, farming potatoes where there is little soil, and hunting for huge basking sharks to get liver oil for lamps.
Some situations are fabricated, such as one scene in which the shark fishermen are almost lost at sea in a sudden gale.
Additionally, the family members shown are not actually related, having been chosen from among the islanders for their photogenic qualities.
The Cripple of Inishmaan by Martin McDonagh is a play set on the Aran Islands at the time of the filming of Man of Aran.
The film won the Mussolini Cup for best foreign film at the 2nd Venice International Film Festival

Global warming is melting the Greenland ice sheet, fast


Cryosat reveals recent Greenland ice loss 
Between 2011 and 2014, Greenland lost around one trillion tonnes of ice.
This corresponds to a 0.75 mm contribution to global sea-level rise each year – about twice the average of the preceding two decades.
These results from the UK Centre for Polar Observation and Modelling (CPOM) at the University of Leeds combine data from the CryoSat mission with a regional climate model to map changes in Greenland ice-sheet mass. 
source : ESA

From The Guardian by John Abraham

The Greenland Ice Sheet is losing 110 million Olympic size swimming pools worth of water each year.

A new study measures the loss of ice from one of world’s largest ice sheets.
They find an ice loss that has accelerated in the past few years, and their measurements confirm prior estimates.

As humans emit heat-trapping gases, we expect to see changes to the Earth.
One obvious change to be on the lookout for is melting ice.
This includes ice atop mountains, ice floating in cold ocean waters, and the ice within large ice sheets or glaciers.
It is this last type of ice loss that most affects ocean levels because as the water runs into the oceans, it raises sea levels.
This is in contrast to melting sea ice – since it is already floating in ocean waters, its potential to raise ocean levels is very small.

So measuring ice sheet melting is important, not only as a signal of global warming but also because of the sea level impacts.
But how is this melting measured? The ice sheets on Greenland and Antarctica are huge and scientists need enough measurements in space and time to really understand what’s going on.
That is, we need high-resolution and long duration measurements to fully understand trends.

In a very recent publication in the journal Geophysical Research Letters, an international team reported on a new high-resolution measurement of Greenland.
The lead author, Malcolm McMillan from the Centre for Polar Observation and Modeling, and his colleagues mapped Greenland with incredibly high resolution (5 km distances).

They accomplished this mapping by obtaining data from the Cryosat 2 satellite.
This satellite uses a technique called radar altimetry to measure the height of surfaces.
It is able to track the elevation of the ice sheets on Greenland with high precision.
If the height of the ice sheet is growing, it means the ice is getting thicker.
If the heights are decreasing, it means the ice layers are getting thinner.

Watch this documentary on Greenland which icebergs are said to be melting.

A simplistic view would be that if ice sheets become taller, then they contain more frozen water.
If they are shorter, they contain less water.
But, this isn’t the entire story.
Scientists also have to account for other changes, such as changes to density, surface roughness, and water content.
When you realize that the Greenland Ice Sheet is thousands of meters thick, and the top layers include both snow and firn (which later get buried and compressed into ice), it becomes apparent that accounting for the constitution of the ice sheet is important when estimating how much water is being delivered to the ocean.

The authors of this study did such an accounting and they discovered that not only is Greenland losing a lot of ice, but the loss varies a lot depending on location and year.
For example, 2012 was a year of incredible ice loss compared to other years.
Also, the western side of the ice sheet is losing much more ice than the eastern side.
They also found that a small part of the ice sheet (less than 1% of the sheet) is responsible for more than 10% of the mass loss.

Why are scientists out flying over Greenland, drilling into its ice, and monitoring it from space?
The answer is that they see it as a bellwether of future Earth.

In total, they estimate approximately 270 gigatons of ice loss per year for 2011–2014.
This result is almost a perfect match to independent measurements made by other researchers and builds our confidence in their conclusions.
To put this in perspective, the Greenland Ice Sheet is losing approximately 110 million Olympic size swimming pools worth of water each year.

New maps chart-Greenland glaciers melting risk

Lead author Malcolm told me:
"Using high resolution satellite data from ESA’s CryoSat-2 mission, we have produced a detailed and comprehensive picture of how Greenland has changed in recent years.
In particular, we have been able to map the changing ice sheet in fine detail, and pinpoint where, and when, the greatest ice losses have occurred.
These observations reveal not only the extent of Greenland’s contribution to sea level in recent years but, thanks to their high resolution, allow us to identify the key glaciers that are showing the greatest signs of change.
The data also enable us to look at how much ice has been lost in each year and, for example, to quantify the large impact on the ice sheet of the record summertime temperatures occurring in 2012.
Within a wider context, satellite records such as these are crucial for systematically monitoring our climate system, and assessing the impact of rising temperatures across Earth’s polar regions.
In particular, they help us to understand the sensitivity of the ice sheet to changes in its surrounding atmosphere and ocean environment, and aid the development of reliable sea level rise projections."

The duration of this study is pretty short (4 years).
I will be very interested to see if the mass loss continues at the same rate in following years.
If the rate of mass loss increases, it may signify a larger future contribution to sea level from Greenland.
This would be bad news for vulnerable coastal cities like Miami and certainly something coastal areas should plan for.
