Signs of Arctic climate change increasing: NOAA state of the Arctic report

Worldwide, 2010 was one of the two warmest years on record, says the 2010 State of the Climate report, released June 27 by the U.S. National Oceanic and Atmospheric Administration.

On the Arctic, the State of the Climate shows how 2010 marked the end of the warmest decade since instrument records began in 1900.

The summer of 2010 in Greenland reveals the speed and breadth of the environmental change occurring in the Arctic, the report says.

In Greenland, warm air from the south was responsible for the longest period and largest area of ice sheet melt since at least 1978, and the highest melt rate since at least 1958, it says/

High summer air temperatures and a longer melt season also occurred in the Canadian Arctic, where loss from small glaciers and ice caps continued to increase.

A combination of low winter snow accumulation and high spring air temperatures also resulted in a record minimum spring snow, says the report, compiled by 400 scientists from 45 countries.

This year’s update on climate information from every continent tracks 41 climate indicators, including the temperature of the lower and upper atmosphere, precipitation, greenhouse gases, humidity, cloud cover, ocean temperature and salinity, sea ice, glaciers, and snow cover.

These indicators show “a continuation of the long-term trends scientists have seen over the last 50 years, consistent with global climate change,” said Thomas R. Karl, director of NOAA’s National Climatic Data Center.

The Arctic section of the State of the Climate says:

• Arctic sea ice extent in September 2010 was the third lowest of the past 30 years. After a record minimum summer sea ice cover in 2007, the upper Arctic Ocean remains relatively warm and fresh, instead of salty, “a condition that is affecting marine biology and geochemistry;”

• observations of changes to tundra vegetation indicate “continued increases in greening,” associated with more ice-free, coastal waters and higher tundra land temperatures;

• on Sept. 19, 2010, ice extent shrank to its annual minimum of 4.6 million square kilometres. That’s the third-lowest minimum recorded since 1979, higher only than 2008 and the record minimum in 2007. There has been a substantial loss of old, thick ice in the Arctic Basin compared to the late 1980s, with the pack ice in the central Canada Basin changing from a multi-year to a seasonal ice cover;

• “surface air temperatures through the 2010 summer were higher than normal throughout the Arctic, though less extreme than in 2007;”

• vegetation changed and increased on Baffin Island;

• there was more warming in relatively cold permafrost than in warm permafrost in 2010; and,

• a combination of low winter snow accumulation and above-normal spring temperatures created new record-low spring snow cover duration over the Arctic since satellite observations began in 1966;

    • The solution is continued technological advancement- solar, wind, hydroelectric, etc.

      Also, there needs to be a change in the conversation- rather than "Look at Global warming- we should stop pollution!"

      It should simply be "We should stop pollution!"

      Agreed!
      The mythical man-made Global Warming never was a problem, and climate change is a natural part of the earth's continuing evolution.
      I don't know a single person who isn't against doing something about pollution.

      And I don't know a single person who says Global Warming is man-made.

      What the scientific consensus is, held uniformly, is that man-made pollution contributes to and aggravates climate change.

      The people pretending that scientific facts are simply myths are funded by the fossil fuel companies.

      THEY are the ones who are against doing something about pollution.

      Thank you so much for those links.
      Both are alarmist articles that sing the same, "CO2 is pollution" tune.
      One article is from 1999, the other 2007. Never mind!

      Edit: nearly missed the third site, but seeing as it comes from a group that states, "NRDC is the nation's most effective environmental action group..." I doubt there would be much in the way of scientific information there.

      Real scientific information can't be found on FAUX News or with likes of Limbaugh, Hannity, Beck and ORielly. Global warming, as a result of human activity is a fact, and your opinion that it isn't happening is irrelevant. In other words you can look down the tunnel and claim that the light you see is the opening on the other side. However if you don't step off the tracks, the oncoming train will kill you no matter what.

      Now, why doesn't that statement tally with the data?

      Both refer to resolution.
      Basically, you need to look at the green line and the red line. If the red line is below the green line it shows lower temperatures than the long term average.
      The 2010 data clearly shows temperatures were constantly below the long term average during the melt season.
      This data shows the statement, "surface air temperatures through the 2010 summer were higher than normal throughout the Arctic, though less extreme than in 2007" to be incorrect.
      I assume the negative votes were because I dared to show real data that disputes an extremist's view.

      If you haven't the ability to find the Danish Meteorological Institute's website without a link... Life isn't all about links. There isn't a rule that says there has to be a link to everything to make it valid! How do you evaluate TV documentaries or newspaper articles, do you phone the authors and ask for links?

      So, STILL no link.
      I was not asking for a link to the Danish Meteorological Institute's website.

      I was asking for a link to the website where you got the graph, that has it placed within context.

      You know what context is, right?

      That means the article with the chart, that explains it, and points to how your interpretation has NOTHING to do with reality.

      THAT link.

      But, your refusal to provide the link where you got the chart is just like your refusal to say you are not a creationist.

      It's VERY suspicious.

      Your constant evasiveness makes it quite clear:

      You drew that chart yourself.

      If you actually got it from any reputable website, and the text on that website confirmed what you wrote, you would have NO PROBLEM giving the link to the page you got that graphic from.

      But since it came from a Creationist website that you yourself made, you can't provide one.

      According to you the data shown in the chart is incorrect, so what would be the point in supplying you with a link? Would you then say the data is correct and tell me you're now going to look into the lies and distortions written in the article featured here?
      If you have no idea of how to acquire or use data from official agencies, you have no business asserting that the data is incorrect.

      That's because this is only one part of the Arctic, not the entire Arctic. More cherrypicking. And notice it is only their graph of this one part from 2010. No comparison to 2007.

      http://ocean.dmi.dk/arctic/documentation/arctic_mean_temp_data_explanation_newes...

      "Plus 80N Temperatures - explanation.
      The temperature graphs are made from numerical weather prediction (NWP)
      "analysis" data. Analyses are the model fields used to start NWP models. They
      represent the statistically most likely state of the atmosphere, given the
      information available to make the analysis. Since the data are gridded, it is
      straight forward to deduce the average temperature North of 80 degree North.
      However, since the model is gridded in a regular 0.5 degree grid, the mean
      temperature values are strongly biased towards the temperature in the most
      northern part of the Arctic! Therefore, do NOT use this measure as an actual
      physical mean temperature of the arctic."

      The NOAA report is about the Arctic in total, not just one part. And it's laughable that the same people always come here disputing NOAA when it doesn't fit into their agenda, but have no problem posting only parts of other data and trying to pass it off as complete.

      "surface air temperatures through the 2010 summer were higher than normal THROUGHOUT the Arctic, though less extreme than in 2007;”
      You've got 65N to 79N to go.

      The alternative is to use NASA GISS data which consists of one single ground station. That data is used to represent the entire Arctic. Whereas the DMI data cannot be used to represent the entire Arctic, it does accurately represent the state of the Arctic.

      "...do NOT use this measure as an actual physical mean temperature of the arctic"

      What this actually means is, because of the number of data sources, the data gathered is 'lumped together' and collated to produce one single figure, the representative temperature. Just as if you had ten thermometers in your garden, and they all gave a slightly different temperature, taking the average of them would not give you the actual temperature but would still give you useful long-term data with which to work.
      Anyone visiting the DMI site can see the data for themselves. Few, it seems, actually understand it.

      Of coarse not. Enthalpy. The ice is melting. Just like we've always told you. Releasing latent heat of crystalization. The ice melts and carries the heat away as water. Multiply that by thousands of cubic miles of ice melting, and you get a LOT of heat.

      NOAA has deleted from its datasets all but 1,500 of the 6,000 thermometers in service around the globe. Their coverage of the entire Arctic is poor, to say the least, their interpretation of that data seems to be riddled with political ideology. Still, so long as it fits in with your belief system you'll fall for it, as usual.

      Oh, something you may not have read.

      “The Greenland coastal temperatures have followed the early 20th century global warming trend. Since 1940, however, the Greenland coastal stations data have undergone predominantly a cooling trend. At the summit of the Greenland ice sheet the summer average temperature has decreased at the rate of 2.2 °C per decade since the beginning of the measurements in 1987."
      Petr Chylek, Jason E. Box and Glen Lesins, Climatic Change, Volume 63, Numbers 1-2, 201-221, DOI: 10.1023/B:CLIM.0000018509.74228.03.

      “Analysis of new data for eight stations in coastal southern Greenland, 1958–2001, shows a significant cooling (trend-line change −1.29°C for the 44 years), as do sea-surface temperatures in the adjacent part of the Labrador Sea"
      Hanna, E., and J. Cappelen (2003), Geophys. Res. Lett., 30(3), 1132, doi:10.1029/2002GL015797.

      Not everyone thinks the Arctic is burning up.

      You are full of sh**. This is only information for ONE position, North of 80N which you conveniently left out of your post. Wonder why. And I KNOW how to read.

      Yet, that is EXACTLY what you were doing right here, on this website, when you posted that chart.

      You say:
      "Anyone visiting the DMI site can see the data for themselves. Few, it seems, actually understand it."

      And that is the point- either you did not understand it, or you were being purposefully deceptive.

      It seems people here have absolutely no idea of how data works, how to read it or how to read the literature regarding the data.
      The data presented is well regarded and widely used by many agencies. If you choose to deny its accuracy (which, by the way, you did) then that's up to you. Obviously it's best to believe the scaremongering articles rather than data. That's understandable judging by the lack of intelligence displayed within the last batch of abusive comments.

      I knew full well that you would not understand the data and would not be use the data in the way in which it was meant to be used.
      The data was there for you had you been bothered to look for it, you didn't actually need a link (although, you probably did) in order to see the data. It seems you were either too lazy (as previously stated) or lacked the ability to find these things for yourself.
      Hence the reason why you get your information from alarmist articles and the likes of extreme activists whose only knowledge comes from hours of trawling the internet looking for suitable articles to post here.

      Sorry, I seem to have upset you again!
      I knew you wouldn't understand the meaning behind the text within the article you pasted here and it seems I was right.
      Correct, the data is for one position only; all of 80N and above, but even you would have to admit that that is a fairly large 'single position'.

      This is not the first time you have admitted you have no idea of how to interpret data, how to read charts and graphs, and again you admit your knowledge of the subject is gained only from articles in dubious publications and activists' websites.

      Oh, and finally (for now) please tell me (again) that this is the final time you're going to respond to me. I'm getting sick of hearing it and yet it never comes to fruition... much like the claims of an ice-free Arctic. They keep on telling us it's going to happen but reality always steps in. Hopefully reality will step into your life at some point too, it would surely be better than spending so much of your life searching for propaganda with which to prop-up your love affair with the failed Mr. Gore.
      By the way, when old man Gore decides to come clean and admit his part in the scam, will you too denounce the position you have held for so long, as you did when he did a U-turn on ethanol?

      When the temperature is below 0*C, water freezes. When the temperature is above 0*C ice melts. Ice is melting in the arctic. Therefore, the arctic must be getting warmer.

      So, what is your interpretation of the data?

      In principal a good idea, but I'm afraid the mindset of the people who make the decision will only disregard them as liberal crooks, who only want to push the "climate change hoax".

      I think the only way of battling the effects of climate change (biodistress), is to start a grassroots movement which takes matters in their own hands, instead of waiting for politicians to lead who only have the next election in mind. I commend all those people, who almost on a daily basis point out the signs and effects of climate change, but for most people that is an solely academic discussion. I think if one really want to change something one has to motivate wide parts of society to participate. To do this one has to come up with ideas which can be implemented by normal individuals without making big investment and if they can save some money in the process even better (Money is a great motivator). For example why not offer a website (and widely advertise it) with all kinds of information on how to decrease our impact on the climate and on companies who sell products which follow those principals. If people would stop buying products of companies with bad environmental records, change could happen.

Example , getting the schools off grid for emergency shelters in a power outage ( we get hella snow here and that happens almost every year ) , or fire dept . or what have you ?
