Arctic Background / Re: 2017 SWIPA report
« on: April 26, 2017, 04:22:16 PM »

A handy scary summary analysis:


http://gcaptain.com/quickening-arctic-thaw-could-cost-trillions-report/


First part:
OSLO, April 25 (Reuters) – The Arctic’s quickening thaw is melting the permafrost under buildings and roads from Siberia to Alaska, raising world sea levels and disrupting temperature patterns further south, an international study said on Tuesday.    Link: http://www.amap.no/
The frigid region’s shift to warmer and wetter conditions, resulting in melting ice around the region, may cost the world economy trillions of dollars this century, it estimated.
The report by 90 scientists, including United States experts, urged governments with interests in the Arctic to cut greenhouse gas emissions. U.S. President Donald Trump doubts that human activities, led by use of fossil fuels, are the main driver of climate change.
“The Arctic is warming faster than any other region on Earth, and rapidly becoming a warmer, wetter and more variable environment,” according to the study, which updates scientific findings from 2011.
“Increasing greenhouse gas emissions from human activities are the primary underlying cause,” they wrote in the study commissioned by the Arctic Council grouping the United States, Russia, Canada, Sweden, Denmark, Norway, Finland and Iceland.
Arctic warming could have cumulative net costs from 2010-2100 of between $7 trillion and $90 trillion, it said, with harm exceeding benefits such as easier access for oil and gas exploration and shipping, it said.  Link: http://gcaptain.com/ice-class-lng-tanker-forges-path-for-arctic-shipping-super-highway/
The period 2011-2015 was the warmest since records began in 1900. Sea ice on the Arctic Ocean, which shrank to a record low in 2012, could disappear in summers by the 2030s, earlier than many earlier projections, it said.

« on: March 08, 2017, 12:32:19 AM »

In the sea Ice around Antarctica thread the area is currently (record minimum) around 1,500,000 km2 so 5,000km2 - the size of the potential loss of the shelf is quite small in area % terms - probably lost within normally daily increase / decrease figures though it obviously represents a massive volume compared to thin, surface ice.

I can't seem to find any measures of arctic sea ice volume so dont know what fraction it would represent (or if it would skew the figures)

I couldn't help noticing the differences from this to the Piomas "January Average". 

I have taken the liberty of rotating AMSR2 for 21st and putting them side by side.....

Is this significant?  Seems there is thick ice in different areas.

This was Russia’s Arctic weather in 2016
«These kind of temperatures have never before been registered in the region», the country’s Hydrometeorological Center says.

By Atle Staalesen February 03, 2017

The year 2016 became the warmest on the northern hemisphere on record, and temperatures in the Arctic were by far the most extreme, the research center says in a sum-up of the year.

Among the most extreme examples is the Island of Vize, the land located north of Novaya Zemlya, where average temperatures in January was 17 degrees Celsius above normal for the month..................

... and some amazing footage of the ice in this film.   Note sea ice in the first 2 minutes, and again at about 12 minutes in vol 1.  It does show a lot of swell at times though, so the landwater lead wasn't always calm.

Antarctica / Re: Halley base shut down and new crack in Brunt shelf
« on: January 30, 2017, 11:11:23 AM »
I've just started reading the fascinating book on the Trans-Antarctic expedition in 1955-8 by Fuchs and Hillary - The Crossing of Antarctica.

There are great descriptions of the ice forming, conditions and sea state. It would be amazing to link their comments into the actual locations - and compare with current / recent conditions.

In the first two years they initially arrived and set up the Shackleton base in the Weddel sea, at the base of Flichner along the coast from the Halley bay base.  They found that the best way to progress with the ships making the supply run (Dec/Jan) was to use the extensive "landwater" lead that they found along the coast - their name for it.   

There was a section of ice at the shore before the start of the ice shelf proper.  Some stores which were waiting to get to the base and were held here during early 1956 were lost when a section broke away in late March.

The landwater lead would mean that in effect there was no physical buttressing by the sea ice, but clearly the effect of the sea ice was to have a calmer water area - which they often used for their seaplane to take off.

The book is very well illustrated with some great photos.

What happened to the inscription on the Statue of Liberty ?

Not like the brazen giant of Greek fame,
With conquering limbs astride from land to land;
Here at our sea-washed, sunset gates shall stand
A mighty woman with a torch, whose flame
Is the imprisoned lightning, and her name
Mother of Exiles. From her beacon-hand
Glows world-wide welcome; her mild eyes command
The air-bridged harbor that twin cities frame.

"Keep, ancient lands, your storied pomp!" cries she
With silent lips. "Give me your tired, your poor,
Your huddled masses yearning to breathe free,
The wretched refuse of your teeming shore.
Send these, the homeless, tempest-tost to me,
I lift my lamp beside the golden door!"

Wrong door ?

« on: January 27, 2017, 03:16:26 PM »
I imagine the justification for a "new" or discontinuous trend line would be where a significant event has occurred that causes a shift so there is the trend before - and after.

Normal seasonal variations though wouldn't be seen as justifying this (but presumably a major meteorite strike would).  Perhaps change in methodology (visual vs satellite observations?) might also qualify.

Science / Scientists march on Washington - Date tba
« on: January 27, 2017, 02:57:34 PM »
As it will no doubt be a significant event... I thought this would merit a thread on its own (rather than within the Presidential Poll).  No idea if it will become global.....

http://www.scientistsmarchonwashington.com/

Current front page (27 Jan):

What is the Scientists' March on Washington

Welcome!  We want to thank you all for your incredible outpouring of support for this march.  We are working to schedule a March for Science on DC and across the United States.  We have not settled on a date yet but will do so as quickly as possible and announce it here.

Although this will start with a march, we hope to use this as a starting point to take a stand for science in politics.  Slashing funding and restricting scientists from communicating their findings (from tax-funded research!) with the public is absurd and cannot be allowed to stand as policy.  This is a non-partisan issue that reaches far beyond people in the STEM fields and should concern anyone who values empirical research and science. 

There are certain things that we accept as facts with no alternatives.  The Earth is becoming warmer due to human action.  The diversity of life arose by evolution.  Politicians who devalue expertise risk making decisions that do not reflect reality and must be held accountable.  An American government that ignores science to pursue ideological agendas endangers the world.

Please bear with us as pull together our mission statement and further details.  Many more updates to come on Monday.

« on: January 26, 2017, 02:02:06 PM »
Thanks Paddy for comments. 

It was my surprise at the 60 km vs 12/13 km normally that struck me.

I think its actually a case of scale.  See map below - a thin sliver along the coast, or a blob (as NSIDC shows) around Erebus may actually be quite large,

I suspect they would have avoided the "rocking horse" which anyway shows as typically < 50%, so not very solid.

Surely if there is a sleight of hand re "payment" ... that is money that could be used for something more useful than a wall (or reduce debt).  Seems a  shame and unlikely to have any positive spinoffs (unlike NASA for example). 

In the short term though it should ensure a flood of people heading North as they will want to get in early / before jobs are lost etc !

How do the animals that travel across the area fare?  I expect they will need passports and permits now!

...and yet the Polar star experienced more / thicker ice than usual:

http://gcaptain.com/ship-photos-u-s-icebreaker-polar-star-reaches-mcmurdo-station-antarctica/

Quote...
The Coast Guard says that in previous years Polar Star typically worked through approximately 12 to 13 miles of ice to reach McMurdo Station. This year, however, there was more than 60 miles of ice to break with thickness ranging from two feet to more than 10 feet.

“We experienced a significantly larger ice field this year compared to the last several years,” said Capt. Michael Davanzo, commanding officer of the Polar Star. “In several areas, the ice was under considerable pressure and covered with several inches of snow, slowing our progress. Despite these challenges, the crew worked around the clock to prepare the resupply channel before the arrival of the first ship.”

end quote

Looking in NSIDC Chartic this seems odd as it shows next to no ice in the area

Provisional full-year figures for global average near-surface temperatures confirm that last year, 2016, was one of the warmest two years on record, nominally exceeding the record temperature of 2015.
When viewed alongside 2015, the two years are the warmest in an annual series of figures that starts in 1850.
