Potential Record Ice on Lake Superior May Mean a Cooler Summer

AccuWeather Global Weather Center -- 19 February 2014 -- AccuWeather.com report mith no end in sight, the winter of 2014 rages on, ushering in frigid Arctic air and dumping record-breaking snow and ice on much of the nation. This season, ice coverage on Lake Superior has exceeded other measurements in recent history.
"By the long shot this is the most ice we've had on Lake Superior in 20 years," Associate Professor Jay Austin of the Large Lakes Observatory in Duluth, Minn., said. During a typical winter, 30 to 40 percent of the Great Lakes are covered by ice, according to AccuWeather Senior Meteorologist Brett Anderson.
Usually Arctic air swept over the Great Lakes creates lake-effect snow, but modifies the air, making it warmer. This usually makes regions from Ohio through the Northeast a little warmer than it otherwise would be. However, this winter 80 to 90 percent of the Great Lakes are covered in ice. As of Thursday, Feb. 13, 2014, Lake Superior was classified as 90 percent covered. "The Arctic air masses don't get warmed up as much because of all the snow and ice," Anderson said. "There has not been much of a thaw so the ice keeps building up." The last time the ice coverage was even close to this winter's percentage was the winter of 1993/94. At this exact time two years ago, the ice coverage on the Lakes was approximately 9 percent.
Unlike a pond, the depth of the Great Lakes prevent it from being a completely frozen sheet of ice, but instead the ice atop the lakes can actually move with the wind, according to Austin. Due to the ability of the ice to move around, the thickness of the ice across the lakes vary and therefore researchers do not know how thick the ice is in all portions of the lake. So, this makes it hard for scientists to define what freezing over entirely means. Depending on who you ask, Lake Superior already has frozen over, Austin stated. However, with two to three weeks to go until the typical peak of ice coverage in mid-March, the Lakes will only freeze even more. "The ice will become more robust, we are going to have more ice rather than less over the next three weeks," Austin said. Other than the ice jam worries, the ice coverage on the Great Lakes, specifically on Lake Superior, is mounting concerns for the region's climate. "With all of this ice, all the sunlight that hits the surface of the lake is going to get bounced back out into space, so it's going to take longer to get warmer this spring and summer," Austin said. "The lake is going to just start warming this year when it will start cooling off for next year."
This could bring a relatively cool year for the communities surrounding the lake. However, the silver lining of the massive ice coverage is that perhaps it can prevent lake water levels from lowering like they did just last year. "With the ice cover, less water gets evaporated so lake levels stay high and help preserve some of the water," Anderson said. Regardless of the impending impacts of the ice on the region, one thing is for sure, the ice isn't going anywhere, anytime soon. An impending return of the now-infamous polar vortex for the middle of next week ill send temperatures from the Midwest to the Northeast plummeting 15 to 20 degrees below normal. As it drops down to the James Bay in Canada, it will deliver another blast of arctic air for the area. "This type of airmass will give the Great Lakes the potential for a new satellite-era ice coverage record," Anderson said. The winters of 1993 and 1994 had the previous highest since we started monitoring ice coverage with satellites about 30 years ago.
My Uncle lives in Thunder Bay on lake Superior. Asked him about global warming. He said boy you been living in Australia to long, you gone nuts. I said but uncle Bert every one in Australia says the globe is getting warmer. He said come home boy or your mind will be lost forever. You will start voting for the communist party. Then if you do come home we have to take you out behind the barn and shoot you. Now we don't want that do we.
Peter Where are all you global warmin boy's, you aint all hidin now are yu. Not gettin all shy now?? Cat got ya tongue. Peter :pop:

How did Surface Temperatures Rank for January 2014? February 18, 2014; 7:21 PM
The Goddard Institute for Space Studies (GISS) has released their January 2014 global temperature data for land and ocean surface combined.
I realize it is hard to believe for folks in the eastern half of the U.S. and Canada, but January 2014 was the 3rd warmest January in the GISS global temperature record, which goes back to 1880. The top two warmest January months were 2002 and 2003 in which both years averaged 0.72 degrees above normal.

You can clearly see how warm it was compared to normal last month over western Canada and Alaska, while a large portion of eastern North America shivered.
January 2014 averaged 0.70 degrees C. (1.26 degrees F.) above the 1951-1980 average, according to GISS.
January 2014 was also the 3rd warmest January in the Northern Hemisphere and averaged 0.94 C. (1.69 F.) above normal.
In the Southern Hemisphere, last month was the 8th warmest January on record with a temperature anomaly of +0.47 C. (+0.85 F.)

Key FAQ's from the GISS site.........
Q. Why no data from before 1880? A. The analysis is limited to the period since 1880 because of poor spatial coverage of stations and decreasing data quality prior to that time. Meteorological station data provide a useful indication of temperature change in the Northern Hemisphere extratropics for a few decades prior to 1880, and there are a small number of station records that extend back to previous centuries. However, we believe that analyses for these earlier years need to be carried out on a station by station basis with an attempt to discern the method and reliability of measurements at each station, a task beyond the scope of our analysis. Global studies of still earlier times depend upon incorporation of proxy measures of temperature change.
Q. Why use the adjusted rather than the "raw" data? A. GISS uses temperature data for longterm climate studies. For station data to be useful for such studies, it is essential that the time series of observations are consistent, and that any non-climatic temperature jumps, introduced by station moves or equipment updates, are corrected for. In adjusted data the effect of such non-climatic influences is eliminated whenever possible. Originally, only documented cases were adjusted, however the current procedure used by NOAA/NCDC applies an automated system that uses systematic comparisons with neighboring stations to deal with undocumented instances of artificial changes. The processes and evaluation of these procedures are described in numerous publications - for instance, Menne et al., 2010 and Venema et al., 2012 - and at the NOAA/NCDC website.
Q. Why stick with the 1951-1980 base period? A. The primary focus of the GISS analysis are longterm temperature changes over many decades and centuries, and a fixed base period makes the anomalies consistent over time. However, organizations like the NWS who are more focused on current weather conditions work with a time frame of days, weeks, or at most a few years. In that situation it makes sense to move the base period occasionally, i.e. pick a new normal, so that roughly half the data of interest are above normal and the rest below.

Climate change isn't necessarily warmer weather, it's extremes of weather. It seems every year around the world records are being broken for temperatures and rainfall.
I don't see myself as a lefty climate change activist - but on a trip to the UK last April, -9 degrees in April?? Huge snow drifts in the north of Ireland wiping out livestock?? It does seem that it would be no harm to err on the side of caution with regard to enviromental protection
I reckon the only solution is to cull a large proportion of the human race though - we're the cause of it all. A nice global pandemic is what they need, a few people to fall asleep.
If you listen to conspiracy nutjobs, the UN already has a plan for population control in place, it's called "Agenda 21". It is a real document, ratified by 178 countries...

Deep freeze polar vortex
AP
Anybody tired of the "polar vortex" yet? No? Excellent, because it's returning soon with all its tail-whipping winds and freezing temperatures as low as 35 degrees below average.
The expected timetable for the vortex – a name that's not technically accurate in many cases – is that the cold will arrive in the Midwest this weekend and in the following days paint the South and East with misery. If anybody wants to shoot the messenger, although please don't, consult this prognostication yesterday from the Weather Underground's Jeff Masters. Here's part of it:
Temperatures 20°F below normal will likely invade the Upper Midwest on Sunday, and gradually spread southeastwards during the week. The peak cold is predicted to occur late next week, with temperatures 20 - 35° below normal covering much of the eastern 2/3 of the country. As a result of these new model runs, the natural gas market has been soaring ever since early this morning, and is now approaching a five-year high of $6.
That five-year high had been topped as of Wednesday afternoon, with prices soaring to $6.25. That's understandable considering that in the past month, only 4 days have reportedly had below-average demand for natural gas in the United States.
To get an idea of how widespread this chill-fest is looking, here's the 6 to 10-day temperature forecast issued Wednesday night by the NWS Climate Prediction Center. Darker-blue regions represent areas with greater probabilities of below-average cold (and that thin white band is just-about average):
http://www.businessinsider.com/the-polar-vortex-is-returning-this-weekend-2014-2?IR=TSo global warming has bee replaced by climate change. When a champ is losing it is not uncommon for him to move the goal posts. The thing that gave this scam away was the money grab. Big ole A Gore give me all ya money, and the fools just said shit ya. Tax me more baby and the global temperature setting will be adjusted to just right. You have been scammed my friend. Don't shoot the messenger. Peter :pop:

No, global warming is a topic within the subject of climate change.
The Intergovernmental Panel on Climate Change was formed in 1988
You keep posting articles about weather not climate, its winter in the northern hemisphere, I would be surprised if it wasn't cold up there.
Ok, Climate change as you now call it.
Please tell me in your own words, a time in the history of the planet when the climate has not "changed". Please also provide information on the government programs in the past that have "stopped" climate change and the tax amount paid historically to rectify this "climate change" as you now call it. So, to simplify this for you, how many seashells and rocks did prehistoric man have to pay each week to change, stop or increase "climate change" Man you must be able to see this is a scam. The carbon taxes probably go to a Nigerian bank account through an untracable wire transfer. Peter
