Next century's most important place in the world--Greenland?

If one had to pick the region of the world most likely to influence the course of human history this century, the Middle East would be the obvious choice, due to its political volatility and rich oil resources. However, the Middle East may have a significant challenger next century from a seemingly unlikely place--Greenland. Why Greenland? Well, the Greenland ice sheet holds enough water to raise global sea level 7 meters (23 feet). There are worrisome signs that the ice sheet might be more vulnerable than we thought to significant melting near the end of the century, according to research results presented at last week's annual meeting of the American Geophysical Union (AGU) in San Francisco. The meeting is the world's largest annual gathering of climate change scientists.

For climate change scientists, Greenland is clearly the most important place in the world. You could tell this by the way glaciers with unpronounceable names like "Kangerdlugssuaq" rolled off their tongues in a smooth, practiced manner at talks given at the AGU meeting. At least 120 presentations focused on the Arctic or Greenland, and fully 52 of these concerned Greenland. I attended roughly 20 of these talks, and most of the presenters made it clear that they were quite concerned about the future of Arctic sea ice and the Greenland ice sheet, particularly in light of the astounding Arctic sea ice melt that occurred in 2007. A number of these talks raised the possibility that we've reached a tipping point in the Arctic. A complete loss of summertime sea ice may occur between 2013 and 2040, three of the presenters said, with the resulting warming dooming the Greenland ice sheet to a slow but inevitable melting process over a period of centuries. None of the presenters expressed the view that the current melting of the Greenland ice sheet and Arctic sea ice was due to a natural cycle that would completely halt or reverse in the next few years or decades.

At a talk on "The Recent Arctic Warm Period", Dr. Jim Overland, an Arctic expert with NOAA's Pacific Marine Environmental Laboratory, didn't offer his view on whether a tipping point had been reached. Instead, he asked the audience to vote. The options he presented:

* A The melt back of Arctic sea ice observed in 2007 is permanent and will not lessen.
* B Ice coverage will partially recover but continue to decrease.
* C The ice would recover to 1980s levels but then continue to decline over the coming century.

Both Options A and B had audience support, but only one brave soul voted for the most conservative option C.

The latest news from Greenland
I was amazed see the tremendous breadth and intensity of research efforts focused on Greenland and the Arctic, presented at AGU. Extra funding has been given to research efforts as part of the International Polar Year (IPY) program, scheduled to run March 2007 through 2009. Satellites like Icesat and GRACE measure the extent of Greenland's ice from above, aided by a fleet of small and large research aircraft. Scientists now have unmanned aircraft that can use runways or be launched by slingshot that can measure the extent of Greenland's melt water lakes. The air armada will be joined next year by the Total Pole Airship, the first blimp used for Arctic studies. Manned and unmanned submarines measure the thickness of the sea ice surrounding the island, and both permanent and temporary bases dotted across Greenland and the polar sea ice house scientists doing land-based studies. Ships and buoys also add data from the ocean areas.

A short list of the results presented at AGU all point to an ice sheet in peril:

- Melting of snow above 2000 meters elevation on Greenland reached a new record in 2007 (Tedesco, 2007).

- Leigh Stearns of the University of Maine's Climate Change Institute showed that the contribution of Greenland melting to global sea level rise has doubled in the last five years. According to the 2007 IPCC report (see Figure 4.18), Greenland may account for as much as 10% of the total global annual sea rise of about 3-4 mm/year (approximately 1.5 inches per decade).

- Sea Surface Temperatures (SSTs) have warmed over 5° C (9° F) over the waters west of Greenland since 1990 (Figure 1, to the right). This has caused the ice-free season to increase by over 60 days per year along the coast.

- The Greenland ice sheet has experienced conditions as warm as those today in the past. Lowell et al. (2007) found organic remains in eastern Greenland that had just been exposed by melting ice, and dated these remains at between A.D. 800 to 1014. Thus, this portion of Greenland was ice-free about 1000 years ago, and temperatures were presumably similar to today's. Erik the Red took advantage of this warm period to establish the first Norse settlements in Greenland around 950 A.D. However, the climate cooled after 1200 A.D., and the Norse settlements disappeared by 1550.

Hydrus - check out the coldfront surf pictures on aurasurf.com - they were from 12/17 and 12/21 - we do rock and roll. I am old so I hang with the groms and I can't get a tube......but yesterday the guys were rockin' although only the ones who were watching closely caught the day.

Hydrus, that is why I also became a UW groupie. I get to see well in advance the potential for weather that will set up my waves. I'd say that in the GOMEX our waves are really dictated by mother nature. I watch the hurricanes and I watch the coldfront between the two there is almost a few windows of opportunity a month, almost --occasionally it's just flat forever it seems. When I got out yesterday there yesterday there just three/four other guys it was real relaxed and I am still buzzing from the day. The hard part for me is when I have to work or be a responsible mom/wife and I miss the window of opportunity. The search for waves has really been a good thing for me - it open the doors to a whole new awareness - weather on the computer box and most importantly weather that I see, smell and feel. I started surfing late in life (my kid taught me) till that point I NEVER knew which way the wind was blowing, couldn't tell which way the wind was blowing, wind change direction?, cold fronts?, a fetch?, a clipper? Total dull in the senses for awareness. Now, the slightest change and I notice, I discovered (after 18 years living about a mile from the beach) that in the early morning if surf is up I can hear it. I never listened before! Now I get up to listen to the cold fronts pushing through in the middle of the night - Whew!

MichaelSTL, how or where did you get that number? I have never seen that before.

Not that it would change my thinking.
I'm not comfortable with a bunch of weathermen creating a brand new science
the science of climate change
and then claiming consensus, saying it's settled and all the facts are in, and slamming the door shut.
When the hypothesis - theory - has not even been proven.

SurfMom-It always seems difficult to get good riding waves in the G.O.M. Some years are so much better then others.But when the storms are brewing such as the winter storms of 82 & 83 and all the tropical cyclones we have had--then surfs up.

speaking of surf, had a nice westerly come through yesterday in the GOMEX, water temp 68, blue skies, bright sun. Waves were good from 9:00 till 11:30 when the wind dramatically switched north and then the water got all disorganized. Got some sweeet rides - in the chest high range - no seaweed, no red tide. Looks like the next front will be a small wave maker this Monday - fingers crossed

Weather 456-About what time period were those colonial days?


anytime between the introduction of slavery in the Caribbean and 1938. The introduction varies throughout the Caribbean. In this period, most of society was based on the plantation system.

But the scientists see few signs that government leaders anywhere are even prepared to take the simple measures of stockpiling food or of introducing the variables of climatic uncertainty into economic projections of future food supplies. The longer the planners delay, the more difficult will they find it to cope with climatic change once the results become grim reality.

Take a wild guess when that was written before hitting this link.

Baha, my comments regarding the good Dr are based upon the fact that he is only pushing the "doom" debate. Granted he is not pushing his own personal opinion - but given the content of his posts, one can only feel that he subscribes to this line of thought.

Reagrding weather - and I mean weather not climate, I have highest respect and regard for Dr M and this will never change.

I just feel, and I don't think I'm alone on this, this specific forum is not the appropriate stage for such a topic that has been politiced - and now taxed debate.

In the reactions to the Inhofe story which received world coverage and sent alarmist blog sites into a fury or deep depression, there were the usual claims that the scientists were bought off. The following image submitted by Alan Siddons says it all when it comes to relative funding of the alarmist side and the skeptic side of the science since 1990 based on actual numbers.

Photobucket


It is so ironic that in the usual ad hominem attacks to any coverage of a skeptic, the accusation ‘bought and paid for’ is usually found though they rarely question the science. They call that projection in psychology - defined as is a psychological defense mechanism whereby one “projects” one’s own undesirable thoughts, motivations, desires, and feelings (and in this case actions) onto someone else.

I dunno. I think I'm GWed out for now. I am still pretty agnostic about the MM effects on climate change, but I do believe it's a serious issue that requires further dialogue and study so that we can react effectively.

I'm interested in that period DR. M talked about (and BTW, I think the person who accused Dr. M of hyping the issue is being judgemental - the Doc seemed to be making a report without injecting too much of his personal views) so I'm off to do some online reading and outdoor activities.

Have a great day, everyone!

Lin, I am not trying to prove anything to anybody - I was trying to illuminate where I am coming from as a lay person. Most (all?) people on this blog have forgotten more about climate science than I know - I was more trying to give an insight into why I am concerned - as a layman.

It has been a great experience and refreshing to see all the comments....either direction on this topic.
There is a lot of research information that is not yet presented and also a lot of information presented that is just plain wrong from the scientific community.
I have found it worth the effort to examine as much as I can on the subject and I hope others will also.
For now it seems that many have been Blinded By the Science.

Once this blog re-establishes a two-sided conversation where each side is given the freedom to speak without being shunned and banned by several on this blog as I am, this blog will be back to what it was before it was hijacked by those same individuals.


lin, let's not get melodramatic here. Most of these people have just agreed to disagree with you. That's the point of the ignore button; you can choose who you see, which I think is only fair. Other than that, I think the debate here has been relatively clean.

I think I mentioned when we first started chatting (was that after Noel?) that u and I prolly see a lot alike on a lot of issues. However, I'm like a lot of other people here in expecting you (and anybody else, for that matter) to bring your evidence to the table with you. Repeated statements of your opinion without new information will come across as rehashing to some. Expect to get the ignore button in these cases.

OTOH, you will get respect, even from those who disagree with you, if you keep your argument rational and supported. I've disagreed with a lot of things you have said, but I think you are trying to do that. So dialogue is possible.

I hope u can hack it in the 2008 season. I think it should be fun . . .

Syd - you have taken a snapshot of just one year. Even in our lifetimes there have been hooter days, colder nights, wetter summers and hotter winters.

2006 had less hurricanes than 2005 - does that mean we are in a Global Cooling period ?

Every 30 something in Britain remembers the summer of 1976 as being long and hot - with nothing like it since - perhaps that may have been the gloabl warming peak for the century?

Sorry to be sarcastic - but it is frustrating when people take the smallest of snapshots in time to predict what the future holds. The facts are that over millions of years there have been periods of greater warmth and cold than we are experiencing now - and a million years ago we weren't burning fossil fuels, burying plastic bags and issuing carbon credits.

In the following post, the important words have been highlighted for your perusal.

*****************************

350. Patrap 4:21 PM GMT on December 22, 2007
Global climate change poses risks to human health and to terrestrial and aquatic ecosystems. Important economic resources such as agriculture, forestry, fisheries, and water resources also may be affected. Warmer temperatures, more severe droughts and floods, and sea level rise could have a wide range of impacts. All these stresses can add to existing stresses on resources caused by other influences such as population growth, land-use changes, and pollution.
Climate Change in Louisiana

Below are some of the potential impacts:

* By 2100 temperatures in Louisiana could increase about 3F (with a range of 1-5F) in spring and summer, slightly less in winter, and slightly more in fall. The frequency of extreme hot days in summer is expected to increase along with the general warming trend.
* At Grand Isle, Louisiana, sea level already is rising by 41 inches per century, and is likely to rise another 55 inches by 2100.

************
????
In Naples, there hasn't been anywhere near such an increase in sea level, not even 'inches' plural over the last century. How can it be that Naples is not experiencing the sea level rise and Grand Isle is. HMMMM
Is Grand Isle surrounded by a moat or something that would allow such a phenomenom to occur?
************

* Louisiana currently is losing coastal wetlands at a more rapid rate (approximately 50 square miles a year) than any other coastal state or region in the United States.
* Louisiana's low-lying delta coastal wetlands are a unique case ..these wetlands receive large deposits of sediment from the outflow of the Mississippi River. These deposits provide wetlands with a natural defense against the effects of sea level rise. However, because the surface is subsiding faster than sedimentation is occurring, Louisiana wetlands could be flooded extensively even by relatively small changes in sea level. Cumulative costs of sand replenishment to protect Louisiana's coast from a 20-inch sea level rise by 2100 could be $2.6-$6.8 billion. sea level rise update
* In addition, warmer seas could contribute to the increased intensity, duration, and extent of harmful algal blooms. These blooms damage habitat and shellfish nurseries, can be toxic to humans, and can carry bacteria like those causing cholera. Brown algal tides and toxic algal blooms already are prevalent in the Atlantic. Warmer ocean waters could increase their occurrence and persistence.
* Along Louisiana's coast, viral and bacterial contamination of shellfish has repeatedly caused illness. Warming in the Caribbean may have contributed to these ill-nesses; future warming combined with local pollution most likely would continue to damage fish and shellfish and thus affect human health.

********************

I know..it's the writers who are reading the reports all wrong a getting the data confused..yep that's the reason.

Well seeing as the discussion has continued...

I am not a climate scientist - I am a person who has been warned that if we do not address this issue then my nieces children may not have a future - this is quite disturbing. I have also observed the Northwest Passage open for the first time in my lifetime THIS YEAR!! Record flooding in Africa, Vietnam, Britain and Europe - a severe drought in China to sy nothing of a record drought in Australia (I know some of the people effected by this) Two Cat 5 hit Central America - Two Cat4/5 hit China etc etc. I am definitely open to the people who dispute Global Warming (or it's cause) but I feel that there is enough information coming my way to lead me to be concerned about this possibility and that to be written off as a 'Climate Change Wonk' is maybe a tad severe LOL

lindenii - At last a refeshing voice of reason to put this into context. My biggest disapointement with the Weatherunderground forum is the respected Dr M himself is now using it to push a political message down our throats. These "experts" are using 5 minutes worth of data, from a million year old library to preach complete garbage and myth. These are the very same geeks, who thirty years ago were preaching that we were entering an ice age! The reality is that people are sick to death with the same drivvle from so called "experts". These experts claim to to be able to predict world climate for the next hundred years - but failed entirely, to see a Cat 1 hurricane form and make landfall this year.

It's good we should be living better, less waste and cleaner - but this is not going to change a thing when it comes to climate.

The "scientists" are simply justifying their own existence and gloryfying in their 5 minutes of fame in the latest "Climatologist Idol" contest. Like all fads, this will die and go away and we will be left with the harsh reality of what is happening in the world today to real people and not this eco-warrior bulls**t that is boring the crap out of us.

If the spent just 10% of the time effort and money that goes into this worthless debate on AIDS and Malaria research - that has a better probability of saving the earth and actually changing peoples life.

The question the world is struggling with is how to avoid "The Tragedy of the Commons" with regard to the ecosystem. Carbon Credit, wetland restoration and other trading systems are all attempts to internalize the costs into the price of the products involved. Since I am of the opinion that "The Market" is based on as much of a utopian fantasy as "The Commune" I am not all that sanguine as to the outcome of the current hullaballoo.

All these stresses can add to existing stresses on resources caused by other influences such as population growth, land-use changes, and pollution.
Climate Change in Louisiana

Below are some of the potential impacts:

* By 2100 temperatures in Louisiana could increase about 3F (with a range of 1-5F) in spring and summer, slightly less in winter, and slightly more in fall. The frequency of extreme hot days in summer is expected to increase along with the general warming trend.
* At Grand Isle, Louisiana, sea level already is rising by 41 inches per century, and is likely to rise another 55 inches by 2100. Louisiana currently is losing coastal wetlands at a more rapid rate (approximately 50 square miles a year) than any other coastal state or region in the United States.
* Louisiana's low-lying delta coastal wetlands are a unique case ..these wetlands receive large deposits of sediment from the outflow of the Mississippi River. These deposits provide wetlands with a natural defense against the effects of sea level rise. However, because the surface is subsiding faster than sedimentation is occurring, Louisiana wetlands could be flooded extensively even by relatively small changes in sea level. Cumulative costs of sand replenishment to protect Louisiana's coast from a 20-inch sea level rise by 2100 could be $2.6-$6.8 billion. sea level rise update
* In addition, warmer seas could contribute to the increased intensity, duration, and extent of harmful algal blooms. These blooms damage habitat and shellfish nurseries, can be toxic to humans, and can carry bacteria like those causing cholera. Brown algal tides and toxic algal blooms already are prevalent in the Atlantic. Warmer ocean waters could increase their occurrence and persistence.
* Along Louisiana's coast, viral and bacterial contamination of shellfish has repeatedly caused illness. Warming in the Caribbean may have contributed to these ill-nesses; future warming combined with local pollution most likely would continue to damage fish and shellfish and thus affect human health.

The above are based on from the Environmental Protection Agency's report on climate change, which uses data from the Third Assessment Report of the Intergovernmental Panel on Climate Change (2001)"

Louisiana is the 9th highest emitter of C02 of all 50 states and the 22nd most populous.

Baha.....you might want to do some research on the Medieval Warm Period for the temps you were asking about.

Here's a page with research reports....but there is much more available with just a search.

Question.....?


Is any of the data injected into Climate Models ever revealed to the public?

I love this site but am noticing a very rapid and somewhat disturbing change.... It is becoming more of a political forum for global warming and less about weather. Perhaps the should be a new site created by those that support this global warming stuff and leave this site strickly to weather forcasting?


What is happening is that some of us have finally gotten the gumption to speak out and express our serious doubts concerning the computer driven weather models and how they might be skewed by political bias of those in charge.

Only by 'outing those individuals and their political biases' can we begin the process of truly analyzing the data in an unbiased manner. Hardy a day goes by that a new and improved instrument isn't brought out for all to see and use. What is left out is how to accurately use it.

There are some among us who would go back in time to points where such instrumentation did not exist and attempt to make observations based upon the new instrumentation. That is simply wrong and they probably know it.

I am , for example, being shunned by several on this blog, not because I am vulgar or call names; but, it is because I have a differing viewpoint and am not afraid to be insulted by their ilk. In other words, I do not blink.

Once this blog re-establishes a two-sided conversation where each side is given the freedom to speak without being shunned and banned by several on this blog as I am, this blog will be back to what it was before it was hijacked by those same individuals.

Well looking at it that way,
the entire UN agenda and IPCC reports are implied too.

CENTRAL AMERICA AND THE CARIBBEAN REGION....

An abundance of clear, sunny skies and fair weather is affecting most, if not all, of the Caribbean this afternoon. The culprit is large amounts of dry stable air that sits over the region. The only shower activity remains south of 10N from Lower central America across Northern South America. Stray showers may occur within patches of clouds and moisture being transported by the trades. This will be one of the many beautiful Saturdays that the region will experience between now and May – the dry season.
