Corridor.<br>
Winemakers are also planting varieties of grapes that do better in
the heat and shading their grapes with more leaf canopy.<br>
Minor weather variations that occur vintage to vintage can change
the grapes' sugar, acid and tannin content, which affects the wine's
taste and characteristics.<br>

heat source found beneath large Antarctic glacier</a></b><br>
"When you find helium-3, it's like a fingerprint for volcanism,"
researcher Brice Loose said. "We found that it is relatively
abundant in the seawater at the Pine Island shelf."<br>
By Brooks Hays - June 25, 2018 at 9:56 AM<br>
June 25 (UPI) - Scientists have discovered a volcanic heat source
underneath Antarctica's Pine Island Glacier.<br>
Already threatened by rising atmospheric temperatures and warming
ocean currents, the West Antarctic Ice Sheet's enemy list continues
to grow.<br>
Scientists discovered the heat source while analyzing trace gases
from water samples collected near the glacier's coastal shelf.<br>
"I was sampling the water for five different noble gases, including
helium and xenon," Brice Loose, a chemical oceanographer at the
University of Rhode Island's Graduate School of Oceanography, said
in a news release. "I use these noble gases to trace ice melt as
well as heat transport. Helium-3, the gas that indicates volcanism,
is one of the suite of gases that we obtain from this tracing
method."<br>
Loose and his colleagues weren't looking for volcanism. When they
measured the elevated levels of helium-3, they assumed it was an
anomaly or a mistake.<br>
But followup measurements confirmed the helium isotope spike wasn't
an aberration.<br>
"When you find helium-3, it's like a fingerprint for volcanism. We
found that it is relatively abundant in the seawater at the Pine
Island shelf," Loose said.<br>
Pine Island Glacier is losing ice mass faster than any other glacier
in Western Antarctica, but researchers don't believe the volcanic
heat source is the main driver of the glacier's melting.<br>
"There are several decades of research documenting the heat from
ocean currents is destabilizing Pine Island Glacier, which in turn
appears to be related to a change in the climatological winds around
Antarctica," Loose said.<br>
The volcanic heat source is, however, one more factor to account for
when modeling the stability of the West Antarctic Ice Shelf. The ice
shelf's stability has serious implications for the future of sea
level rise.<br>
The analysis of trace gases - published in the journal Nature
Communications - suggests the volcanic heat source is putting off as
much as 25 times more thermal energy than a dormant volcano. And
while climate change explains the bulk of the glacier's melting, the
new heat source is most likely accelerating the glacier's ice loss.<br>
"The discovery of volcanoes beneath the Antarctic ice sheet means
that there is an additional source of heat to melt the ice,
lubricate its passage toward the sea, and add to the melting from
warm ocean waters," said Karen Heywood, a professor at the
University of East Anglia. "It will be important to include this in
our efforts to estimate whether the Antarctic ice sheet might become
unstable and further increase sea level rise."<br>

Abstract<br>
<blockquote>Tectonic landforms reveal that the West Antarctic Ice
Sheet (WAIS) lies atop a major volcanic rift system. However,
identifying subglacial volcanism is challenging. Here we show
geochemical evidence of a volcanic heat source upstream of the
fast-melting Pine Island Ice Shelf, documented by seawater helium
isotope ratios at the front of the Ice Shelf cavity. The
localization of mantle helium to glacial meltwater reveals that
volcanic heat induces melt beneath the grounded glacier and feeds
the subglacial hydrological network crossing the grounding line.
The observed transport of mantle helium out of the Ice Shelf
cavity indicates that volcanic heat is supplied to the grounded
glacier at a rate of ~ 2500..., which is ca. half as large as the
active Grimsvotn volcano on Iceland. Our finding of a substantial
volcanic heat source beneath a major WAIS glacier highlights the
need to understand subglacial volcanism, its hydrologic
interaction with the marine margins, and its potential role in the
future stability of the WAIS.<br>

Introduction<br>
<blockquote>The stability of Pine Island Ice Shelf and the Pine
Island Glacier are of paramount importance to sea level rise and
the mass balance of the West Antarctic Ice Sheet (WAIS)1.
Geothermal heat sources and the production of subglacial water can
influence the bottom boundary condition that partly determines the
glacial mass balance... Variability in the subglacial water
supply..., including that caused by intermittent heat flux6, can
lead to ice sheet instability. Thus, the existence of subglacial
volcanism impacts both the stable and unstable dynamics of an ice
sheet such as the WAIS.<br>
</blockquote>
"...that volcanic heat does not contribute significantly to the
glacial melt observed in the ocean at the front of the ice shelf. <font

Internal calving briefly raised fear of flooding along Mendenhall
River, flood watch has since been canceled<br>
The National Weather Service office in Juneau has canceled a flood
watch for the Mendenhall River after the Mendenhall Glacier calved
ice into Suicide Basin.<br>
The basin, uphill from the face of the glacier, contains meltwater
that surges into a jokulhlaup flood each summer. On Monday, an
abrupt change in the basin's water level seemed to indicate another
flood was imminent. Upon further analysis, hydrologists and glacier
experts found ice had broken free from the glacier and was floating
in the basin, sloshing the water within.<br>

A video taken by an unmanned drone controlled by University of
Alaska postgrad Christian Kienholz shows a massive glacial segment
that dropped into Suicide Basin on Monday afternoon, June 25, 2018.
The blue streak of freshly exposed glacial ice shows where the ice
broke from the main body of the Mendenhall Glacier and into the
basin, which poses a persistent flooding risk for the Mendenhall
Valley.<br>

Rick Fritsch, lead forecaster at the Weather Service here, said it
was akin to "dropping a large chunk of ice into a bathtub."<br>
Eran Hood, a glaciologist at the University of Alaska Southeast,
said it was quite a bit more spectacular than that. Hood was among a
group of scientists who were at the spot when the glacier calved
into the basin. Hood estimates a chunk of ice a fifth of a mile wide
splashed into the basin with a cacophanous roar.<br>
"It was tremendously loud. It sounded like explosions were going
off," he said.<br>
Shards of ice flew into the air, icebergs overturned in the basin,
and free-floating ice soon covered much of the basin's surface.<br>
"It was really, really impressive," Hood said. "We have never seen
any calving event that was this big in this section."<br>
Pictures show a fresh blue gash where dense glacial ice has been
exposed to the air.<br>
"You see these giant new ice cliffs forming where the ice just snaps
off and drops into the water," Hood said.<br>
U.S. Geological Survey hydrologist Jamie Pierce was with Hood.<br>
"Most of us were just at a loss of words. We weren't expecting what
we saw. It defied reason," Pierce said.<br>
At his office in Juneau, Fritsch said that despite the icy events
uphill, "it's pretty obvious that whatever happened in Suicide Basin
has not had any kind of effect (on lake and river levels)."<br>
<a class="moz-txt-link-freetext"

With that in mind, the Weather Service canceled a flood watch that
had been issued Monday afternoon.<br>
Suicide Basin is not wholly understood, Hood said, but studies are
under way to determine its dimensions, activity, and the threat it
poses to the Mendenhall Valley.<br>
Starting in 2011, the basin began collecting and releasing surges of
water beneath the glacier and into Mendenhall Lake and Mendenhall
River. The floods associated with releases in 2016 were the largest
on records that began more than 50 years before.<br>
The basin is like a bowl with an opening on its bottom. That exit is
normally sealed with ice, allowing meltwater to collect within. When
the weight of the water is too great for the icy seal, it lets
loose, sending a surge of water beneath the glacier. It isn't known
how much water the basin can hold.<br>
Monday's event involved an unsupported ledge of ice that jutted over
the edge of the bowl and down into the basin, below the surface of
the water. Ice naturally floats, and when the buoyant pressure
lifting the ice overcame the strength of the ice holding it, the
ledge calved into the basin.<br>
Hood said the ice entering the basin is a lobe separate from the
main flow of the Mendenhall Glacier. He doesn't think this week's
calving increases the flood risk to the Mendenhall Valley, but he
acknowledged that the situation is complicated.<br>
As ice fragments, it becomes more prone to melting, thus increasing
the water in the basin. At the same time, the thinning Mendenhall
Glacier is weaker and less able to hold water within the basin.<br>
"It's something we're actively working on," he said. "The university
and USGS are still working together to monitor it and be able to
better forecast the floods."<br>
Pierce said the next 12 hours should be revealing. Monday's calving
was such a significant event, it should have broken the icy seal
that keeps water in the basin. That doesn't appear to have happened.<br>
"It's re-sealed itself, and if we see (the water level) go back up
again, we will have never seen that before," he said.<br>
If the water level does rise, that might indicate a firmer seal on
the basin, something that would increase the flood danger for the
Mendenhall Valley.<br>

Sea Level Rises: Build the Mall</a></b><br>
June 20, 2018<br>
Sea level is rising. Malls are going bust everywhere. What's the
answer?<br>
<b>Build the biggest mall ever, at sea level.</b><br>
Wall Street Journal:<br>
<blockquote> At a time when store closures are accelerating and
struggling malls pockmark the country, county commissioners in
Florida have approved a plan to build what would be the largest
mall in the U.S.<br>
American Dream Miami would also be the most expensive mall ever
built, according to Canadian developer Triple Five Worldwide Group
of Cos. The 6.2-million-square-foot retail and entertainment
complex would cost an estimated $4 billion, Triple Five says.<br>
The cost would include 2,000 hotel rooms, indoor ski slope,
ice-climbing wall and water park with a "submarine lake," where
guests could enter a plexiglass submarine and descend underwater.<br>
Edmonton, Alberta-based Triple Five secured zoning approval in May
from the Miami-Dade County Commission in an 11-1 vote, and is now
in the process to secure environmental and water permits for the
174-acre site.<br>
The project provides a window into the thinking of North America's
largest mall developers as they confront the revolution in the
shopping world sparked by e-commerce. They recognize it's no
longer enough to fill malls with stores selling clothing, food,
electronics and other merchandise people can more easily buy
online.<br>
Rather developers are filling malls with restaurants, rides,
trampoline parks, gyms, services and other types of entertainment.
This strategy taps into the increasing preference of consumers to
spend their money on experiences as opposed to goods.<br>
</blockquote>
NPR:<br>
<blockquote> The seas are rising, frequently flooding the streets
even when no storms are on the horizon. But that hasn't stopped
foreign investors from shelling out big dollars for Miami real
estate. Many are in it for the relatively short-term investment,
then they'll try to sell before climate change takes its toll,
observers of the local market say.<br>
Visit South Florida and you would have no idea this boomtown was a
subprime war zone just a decade ago. In the aftermath of that
collapse, Miami's skyline was dominated by half-empty buildings
and idled cranes; condo associations had trouble collecting fees,
and billboards advertised lawyers who swore they could wrest back
your security deposit.<br>
The notoriously boom-bust region was bailed out by foreign
investors, who desired hard U.S. assets and a piece of the
sun-kissed Miami dream. Eighty percent cash down payments became
the new thing - and often sight-unseen: About 5 percent of South
Florida foreign buyers snapped up local homes without even
visiting; 18 percent bought with just one visit.<br>
But accompanying this giddy ascent has been a gurgling anxiety at
sea level.<br>
Locals are increasingly finding even inland streets flooded during
high tide - the rising Atlantic Ocean sluicing through the porous
limestone that South Florida is built upon. Catfish and even an
octopus have been spotted in the floodwaters, as storm drains
operate in reverse. Miami Beach is eyeing $500 million in
infrastructure upgrades, installing 80 new pumps over a decade to
redirect floodwaters back to the ocean. The city of Miami approved
a bond offering that would include about $200 million for projects
to prevent flooding and mitigate sea-level rise.<br>
Even so, Zillow estimates that by the end of the century, nearly
half a million Miami homes could be submerged. That's tops in the
country.<br>
</blockquote>
Miami New Times:<br>
<blockquote> Miami tops of a lot of nationwide lists, especially
when those lists have to do with climate change or luxury housing.
The Magic City is the second-most vulnerable to coastal flooding
in America and the most vulnerable to hurricanes - yet somehow
it's also one of the most expensive real-estate markets on Earth.<br>
Even as the 305 has become the most expensive place for
millennials, with the highest percentage of "worst-case needs"
renters and requiring residents to spend a higher share of income
on rent than any other American city, Miami-Dade has doubled down
on luxury houses and condos, building so many new high-end units
that it could take four years just to fill them all. In fact,
Miami also takes first place in a ranking of cities with assets
exposed to coastal flooding. In sum, if this city sinks thanks to
sea-level rise and climate change, thousands of expensive homes
are going down with it.<br>
But for the billionaire preppers hoping to stick it out in South
Florida, Arkup is here. Arkup is a new design firm that
specializes in solar-powered, sustainable, "luxury livable
yachts," or "arks."<br>
The 4,350-square-foot, four-bedroom, four-and-a-half-bathroom
floating homes are as mobile as any large boat - with 272
horsepower - but they can also become as stable as any house on
land. Each unit is equipped with retractable hydraulic "spuds"
that can lift the structure out of the water onto 40-foot stilts.<br>
Arkup says its designer vessels are flood-resistant, capable of
withstanding Category 4 hurricane winds, fully off-the-grid, and
able to motor away from serious tropical storms. That's why their
makers are marketing them as "future-proof."<br>
