Arctic journey shows the glaring effects of climate change</a></b><br>
A Finnish icebreaker has completed the Northwest Sea passage, which
links the Atlantic and Pacific oceans across the Arctic. The trip,
from Vancouver to Greenland’s capital city Nuuk, took 24 days -- a
new record, in part because climate change has melted sea ice,
making the journey easier. Frank Jordans, an Associated Press
reporter who took the trip, joins Hari Sreenivasan from
Greenland. video 3:41 <a class="moz-txt-link-freetext"

sets mark for earliest Northwest Passage transit</a></b><br>
NUUK, Greenland (AP) - After 24 days at sea and a journey spanning
more than 10,000 kilometers (6,214 miles), the Finnish icebreaker
MSV Nordica has set a new record for the earliest transit of the
fabled Northwest Passage.<br>
The once-forbidding route through the Arctic, linking the Pacific
and the Atlantic oceans, has been opening up sooner and for a longer
period each summer due to climate change. Sea ice that foiled famous
explorers and blocked the passage to all but the hardiest ships has
slowly been melting away in one of the most visible effects of
man-made global warming.<br>

Missing from "An Inconvenient Sequel," Al Gore's New
Climate-Change Documentary</a></b><br>
Intentionally or unintentionally, "The Uninhabitable Earth" leaves
room for something "An Inconvenient Sequel" does not: grief. The
present and possible future ravages of climate change, on our own
species and others, are enormously, often overwhelmingly sad, and
most of us would rather not contemplate them. Wallace-Wells, as a
journalist, isn’t professionally obligated to pivot away from the
worst-case scenarios, and he makes the unusual decision to leave us
staring at them. The vantage isn’t pleasant, but its provision
feels, oddly, like a gesture of respect: for once, we’re given a
chance to absorb and reflect, and, in time, find our own way to a
response.<br>

global warming gets real: inside Nasa's mission to the north
pole</a><br>
</b><font size="-1" color="#666666"><font color="#000000">For 10
years, Nasa has been flying over the ice caps to chart their
retreat. This data is an invaluable record of climate change.
But does anyone care? By Avi Steinberg<br>
Thursday 27 July 2017 <br>
From the window of a Nasa aircraft flying over the Arctic,
looking down on the ice sheet that covers most of Greenland,
it’s easy to see why it is so hard to describe climate change.
The scale of polar ice, so dramatic and so clear from a plane
flying at 450 metres (1,500ft) - high enough to appreciate the
scope of the ice and low enough to sense its mass - is nearly
impossible to fathom when you aren’t sitting at that particular
vantage point.<br>
But it’s different when you are there, cruising over the ice for
hours, with Nasa’s monitors all over the cabin streaming data
output, documenting in real time - dramatising, in a sense - the
depth of the ice beneath. You get it, because you can see it all
there in front of you, in three dimensions.<br>
Imagine a thousand centuries of heavy snowfall, piled up and
compacted into stone-like ice atop the bedrock of Greenland, an
Arctic island almost a quarter the size of the US. Imagine all
of modern human history, from the Neolithic revolution 12,000
years ago - when humans moved from hunting and gathering to
agriculture, and from there, eventually, to urban societies -
until today. All of the snow that fell on the Arctic during that
entire history is gathered up in just the top layers of the ice
sheet.<br>
Imagine the dimensions of that ice: 1.71m sq km (656,000 sq
miles), three times the size of Texas. At its belly - from the
top layer, yesterday’s snowfall, to the bottom layer, which is
made of snow that fell out of the sky 115,000-130,000 years ago
- it reaches 3,200 metres (10,500ft) thick, nearly four times
taller than the world’s highest skyscraper.<br>
Imagine the weight of this thing: at the centre of Greenland,
the ice is so heavy that it warps the land itself, pushing
bedrock 359 metres (1,180ft) below sea level. Under its own
immense weight, the ice comes alive, folding and rolling in
solid streams, in glaciers that slowly push outward. This is a
head-spinningly dynamic system that we still don’t fully
understand - and that we really ought to learn far more about,
and quickly. In theory, if this massive thing were fully
drained, and melted into the sea, the water contained in it
would make the world’s oceans rise by 7 metres (23ft).<br>
When you fly over entire mountain ranges whose tips barely peek
out from under the ice - and these are just the visible ones -
it’s possible to imagine what would happen if even a fraction of
this quantity of pent-up freshwater were unleashed. You can
plainly see how this thing would flood the coasts of the world,
from Brooklyn to Bangladesh.</font><br>

in Provence: locals blame climate change and arson</a></b><br>
An academic study published this month for the international Society
for Risk Analysis by two French experts on biodiversity and forest
fire management suggests that official policy places too little
emphasis on prevention in the first place, while bans on fire use
for agricultural purposes have led to the disappearance of a
"fire-wise" culture among communities.<br>
The authors Thibaut Fréjaville and Thomas Curt argue that the
suppression policy itself may even have resulted in the build-up of
biomass that increases the hazard of massive fires and lengthens the
wildfire "season".<br>
Strongly questioning the sustainability of the fire policy pursued
by France and other Mediterranean countries, the authors warn that
the approach could be the origin of a new generation of wildfires
that will prove even more intense and difficult to suppress.<br>
Back in Carros, there is optimism that moves to plant new trees and
repair forest beds can produce tangible results within 10 years.<br>

has been extremely important to us," said the mayor, Scibetta. "We
do have other forests but it is still sad to see it being destroyed
like this."<br>
