Record warmth at the top of the Greenland Ice Sheet

The coldest place in Greenland, and often the entire Northern Hemisphere, is commonly the Summit Station. Located at the top of the Greenland Ice Sheet, 10,551 feet (3216 meters) above sea level, and 415 miles (670 km) north of the Arctic Circle, Summit rarely sees temperatures that rise above the freezing mark. In the 12-year span 2000 - 2011, Summit temperatures rose above freezing only four times, according to weather records researcher Maximiliano Herrera. But remarkably, over the past week, temperatures at Summit have eclipsed the freezing mark on five days, including four days in a row from July 11 - 14. There are actually three weather stations located at the location--Summit, Summit-US, and Summit AWS. The highest reliable temperature measured at any of the three stations is now the 3.6°C (38.5°F) measured on Monday, July 16, 2012 at Summit-US. A 4.4°C reading at Summit in May, 2010 is bogus, as can be seen by looking at the adjacent station. Similarly, a 3.3°C reading from June 2004 is also bad. Records at Summit began in 1987.

Record heat leads to major flooding in Greenland
The record heat has triggered significant melting of Greenland's Ice Sheet. According to the Arctic Sea Ice Blog, on July 11, glacier melt water from the Russell Glacier flooded the Watson River, smashing two bridges connecting the north and south of Kangerlussuaq (Sønder Strømfjord), a small settlement in southwestern Greenland. The flow rate of 3.5 million liters/sec was almost double the previous record flow rate. The latest forecast for Summit calls for cooler conditions over the coming week, with no more above-freezing temperatures at Summit.

Another huge iceberg calves off of Greenland's Petermann Glacier
A massive ice island two times the size of Manhattan and half as thick as the Empire State Building calved off of Greenland's Petermann Glacier on Monday, July 16, 2012. According to Andreas Muenchow, associate professor of physical ocean science and engineering at the University of Delaware's College of Earth, Ocean, and Environment in his Icy Seas blog, the break-off point has been visible for at least 8 years in satellite imagery, and has been propagating at 1 km/year towards Nares Strait. The same glacier calved an iceberg twice as big back on August 4, 2010--the largest iceberg observed in the Arctic since 1962. The freshwater stored in that ice island could have kept the Delaware or Hudson rivers flowing for more than two years, or kept all U.S. public tap water flowing for 120 days. “While the size is not as spectacular as it was in 2010, the fact that it follows so closely to the 2010 event brings the glacier’s terminus to a location where it has not been for at least 150 years,” Muenchow said in a university press release. “Northwest Greenland and northeast Canada are warming more than five times faster than the rest of the world, but the observed warming is not proof that the diminishing ice shelf is caused by this, because air temperatures have little effect on this glacier; ocean temperatures do, and our ocean temperature time series are only five to eight years long — too short to establish a robust warming signal.”

Figure 2. Look familiar? Two years ago, a 100 square-mile ice island broke off the Petermann Glacier. It was the largest iceberg in the Arctic since 1962. Image taken by NASA's Aqua satellite on August 21, 2010. Image credit: NASA. I've constructed a 7-frame satellite animation available here that shows the calving and break-up of the Petermann Glacier ice island. The animation begins on August 5, 2010, and ends on September 21, with images spaced about 8 days apart. The images were taken by NASA's Aqua and Terra satellites.

That is bad news about the record high temps in Greenland. AND, the increased melting of Russell Glacier.

When I was in the Air Force many years ago (1968), I was stationed at Sondrestrom Air Base. This base was located on the south west coast of Greenland and about 60 miles north of the arctic circle. The airfield is no longer an Air Base but is now known as Kangerlussuaq Airport and at the end of Kangerlussuaq Fjord (Danish name was Søndre Strømfjord)

Here's a picture of what you would maybe see on approach to the runway. Note the ice pack behind the mountains. This is Russell Glacier and what it looked like in 1968.



do you have a picture before they built the airport?

Here's a fact, Dr. Masters has NEVER said that current climate change is caused by humans.



Here's a great big juicy fact for you to chew on. This is the statement about climate change provided by this site, Dr. Masters' site...

"Earth's climate is warming. This time, humans are mostly responsible, and the overwhelming majority of climate scientists agree.

The warming climate is already causing significant impacts to people and ecosystems, and these impacts will grow much more severe in the coming years.

We can choose to take economically sensible steps to lessen the damage, and the cost of inaction is much higher than the cost of action.
"

(I tweaked the format a bit just to help you follow along.)

Today is the 6th year anniversary of the worst storm I've ever seen in my life back in St. Louis. This storm will be remembered as it caused millions of people to loses the power for a week during one of those bad heat waves. This storm also hit Busch Stadium really hard during Cardinals/Braves game and the storm move in so fast that it caught many fans off guard as the winds went from 10 MPH to 100 MPH in a second and couple of debris fell into the crowd (portable concession stands were knocked over, the infield rain tarp was damaged, and plastic sheets used to protect the press box were dislodged). As a result of the storm at least thirty spectators were injured, of whom five were taken to the hospital. This storm causes Busch Stadium to installs "tornado shelters" and to show the radar on scoreboard before the storm strikes. As result, Busch Stadium is now one of the safest stadium to be inside of ANY stadium in USA during the storms. Meanwhile, I remembered seeing 90 MPH winds back in Chesterfield, MO and I witnessed the birth of tornado that eventually touch down in Eureka. Scariest storm I've ever seen. Luckily, I did not lost the power or I would've been fried by the heat.

If you read any of my other posts, you will note I don't disagree with you on the ISSUE; I just found your tone offensive.

But I quoted your post. There wasn't much too it besides the rhetorical? question.

Anyway, let's not argue about this anymore. I looked at some of ur other posts and realized I am normally plussing what u put up, so maybe that one post was just early morning exuberance. I still maintain, though, that thinking about the way you say things can be important - indeed sometimes vital - to how well you achieve your objectives.

My teacher used to say, "It's not what you say, it's how you say it." I think on the internet those words are truer than ever....


I'm sorry for that post this morning that offended you and I will work on refining my post better so that people don't get offended. Again sorry for the rant earlier. I'm tired as it has been a long day and not much sleep anymore due to my new edition at home that keeps me up all night feeding and changing diapers.

De ja vu here in South MS. Same thing happened to us yesterday, it was just later in the day when it occurred. The water is certainly piling up here, making up for lost time in June when it might have rained 2 times the whole month.

Well according to the last month of precipitation anomalies, the ITCZ is actually slightly farther north than normal in the eastern Atlantic and western Africa.
Yes it has been. To add some of my own thoughts on the matter...


Current position of the intertropical front (ITCZ/Monsoon trough) over the African continent





Mean position of the western portion of the ITF relative to climatology





A cool Gulf of Guinea has increased the temperature and pressure gradient over the region, pushing the trough forward and enhancing precipitation. Furthermore, the MJO has been stuck over Africa resulting in large velocity potential anomalies and upper divergence anomalies over the last 31 days. As a result, the Sahel region is well above average in terms of precipitation.


Sahel Precipitation Anomalies (percent of normal) from May to July 18th




So we can expect stronger waves coming off Africa and less SAL across the Atlantic, should these anomalies persist. One problem the anomalous upward motion has created, however, is it has created a lot of anomalous downward motion over the Atlantic. As the MJO phase changes, this anomaly should also change, but it is a bit of a concern and also goes to show that SST anomalies are really not that warm over the MDR as they have been in previous years. Remember, warmer SSTs (relative to the anomaly) means more upward motion.

Back to weather the local mets here say that much of next week down here (s fla) will be affected by SAL. Per Trent Aric's words, (Met on Channel 10 Miami), this looks like it'll be one of the largest Saharan dust areas to move over the area in years.
I can say though on a brighter note for us, compared to the rest of the country the temps have been close to our average nearly all summer thus far.

I've stood up to those here simply to mislead others. I've tried to be a good member of this blog and have kept 90% of my comments weather and climate related.

Thank You Grothar

Tropical Storm Christine (1973) was the easternmost forming Atlantic tropical cyclone on record. Forming as a tropical depression over the country of Guinea on August 25, the system tracked nearly due west for several days before intensifying into a tropical storm on August 28.

Thanks all for the words of support, really making my day. In some ways, I get it, this ain't no Democracy. Rules are expected to be followed, and I technically did violate them. Just didn't expect Jeff to be so curt. Made me feel as though I add nothing here and he'd be happy if I left.
You are taking this too personally. He happened to notice yours. If he noticed anyone else's post they would have been gone too. I don't think Dr. M. knows any of us, except the real good weather nerds. I get the impression that I am talking to adults at times, then children at other times. Maybe he considers us his "classroom" and needs to put his foot down once in a while. And the forecast for the the keys in the next few weeks is Hot, sticky and possibility of breezes if KOG gets his way!!!!
