It is widely being reported that, based on surface-temperature data from the National Oceanographic and Atmospheric Administration (NOAA) and the National Aeronautics and Space Administration (NASA), 2010 was tied for the warmest year on record. What is not so widely reported is that those surface temperature data have been so shamelessly manipulated by climate alarmists that they are entirely unreliable. For a short course in one of the great scientific scandals of all time, go here. There are a number of things wrong with the data produced by NOAA and NASA, but one of the most basic involves the urban heat island effect. It it commonly understood that cities are warmer than the surrounding countryside; you see that every day in weather reports. Thus, weather stations located in urban areas, as many of them are, tend to show increasing temperatures as urbanization and changing land use make the immediate area of the weather station warmer. One study indicated that even a tiny village of 1,000 people can warm temperatures by up to 3.8 degrees F. NOAA and NASA used to acknowledge the urban heat island effect and try to correct for it, but that didn't produce the sort of alarming temperature increases that warmists are looking for. This is how NOAA depicted US temperatures from 1880 to 1999, as posted on NASA's web site in 1999; James Hansen, the head of NASA's climate unit and one of the worst of the alarmists, said truthfully in 1999: The U.S. has warmed during the past century, but the warming hardly exceeds year-to-year variability. Indeed, in the U.S. the warmest decade was the 1930s and the warmest year was 1934. That didn't get the warmists where they were trying to go, so they have now changed the data by eliminating or drastically reducing the urban heat island effect. NASA now shows very different data for the period 1880-1999 from what it published in 1999. This animated GIF shows how the alarmists changed their own data to create the false impression of a climate crisis:

Does Urban Heat Island effect exaggerate global warming trends?
Problem is that there are no remote stations in the Artic.
It's spelled "arctic" and weather stations have been there since 1950. Do you have any other idiocy you'd like to share in this thread?
in populated heat islands.
I guess you did have more idiocy that you wanted to post. One of the stations is located in Eureka, a small staging area used by those hiking to the North Pole. Then there's the Resolute Weather Station, located on a now abandoned air base on Cornwallis Island, pop. 229, over its 2,700 square miles. You know, usually I have to work a bit to expose your complete and utter lack of knowledge of the subjects you post, you are making it easy this time.
Then there's the Resolute Weather Station, located on a now abandoned air base on Cornwallis Island, pop. 229, over its 2,700 square miles. Are you really this stupid? All of the stations are located in areas of human population with associated heat island effects, including the concrete infrared reflections. Of course, there's no NYC there. And up until 1999, even Hanson acknowledged such until it was detrimental to his agenda. Look at how they changed their data. God, you're fucking dumb.
Even the satellites and ocean sensors? You don't know when to quit, do you?
Scientist says Arctic getting colder A Russian scientist says the Arctic may be getting colder, not warmer, which would hamper the international race to discover new mineral fields. An Arctic cold snap that began in 1998 could last for years, freezing the northern marine passage and making it impassable without icebreaking ships, said Oleg Pokrovsky of the Voeikov Main Geophysical Observatory. "I think the development of the shelf will face large problems," Pokrovsky said Thursday at a seminar on research in the Polar regions. Scientists who believe the climate is warming may have been misled by data from U.S. meteorological stations located in urban areas, where dense microclimates creates higher temperatures, RIA Novosti quoted Pokrovsky as saying. "Politicians who placed their bets on global warming may lose the pot," Pokrovsky said. http://www.upi.com/Science_News/2010/04/23/Scientist-says-Arctic-getting-colder/UPI-94431272034113/

Arctic Adds 2000 Cubic Kilometers Of Ice – Despite Reports Of Accelerating Ice Melt These media reports were based on a study published in Science. The authors write in the abstract (emphasis added): Here, we present a multidecadal-scale record of ocean temperature variations during the past 2000 years, derived from marine sediments off Western Svalbard (79°N). We find that early–21st-century temperatures of Atlantic Water entering the Arctic Ocean are unprecedented over the past 2000 years and are presumably linked to the Arctic amplification of global warming.” I’m not sure what they mean by “early 21st century”. Perhaps the years 2000 to 2007? The study says the waters are about 2°C warmer. Here it has to be noted that they are presuming, i.e. postulating. The CO2 link here is a bit of wild speculation. Here’s how Der Spiegel puts it in a report titled Atlantic Current Is Heating Up The Arctic: The experts suspect that the accelerated reduction in sea ice and the measured warming of ocean and atmosphere in the Arctic over the last decades, among other factors, was the result of an enhanced transfer of warmth from the Atlantic. The Fram Straits is even about 1.4° C warmer than during the Medieval Climate Optimum, a time when temperatures in Europe were significantly increased.” And Der Spiegel writes: ‘Cold sea water is decisive in the formation of sea ice, which in turn cools because it reflects sunlight,’ says Thomas Marchitto of the University of Colorado in Boulder. The melting is accelerating by itself.” Media reports like the one in Der Spiegel of course emphasized the supposed vicious circle of the melting Arctic ice dynamic: more melting leads to more warming, which then accelerates the process – all unleashed of course by man-made CO2. If anything they are, perhaps unwittingly, admitting that the Arctic sea ice reduction of the 2000s can be traced back to ocean currents. And as things stand right now, just the opposite is occurring. The Arctic is NOT melting, it’s freezing up again - recovering from its low in 2007, and quite impressively. The Global Rumblings website here reports that 70 trillion cubic feet of ice have been added to the Arctic core since January 2009. That translates to 2000 cubic km – enough to cover Manhattan with 20 miles of ice (or 32,000 Manhattans with 1 meter of ice). The US Navy PIPS 2.0 graphic shows ice thickness. The following comparator shows how it’s the Arctic that has gone green. Source: Global Rumblings Some will say that PIPS is not a reliable indicator of Arctic ice thickness, and so cannot be used reliably. But you can put that rumour to rest, see PIPS WUWT. So why is the Arctic thickening and regrowing, and no longer melting at an unprecedented rate as claimed by the media? This could have to do with the Labrador Current, which flows southward between Greenland and Labrador. Reports say it is slowing down. That means cold water is not getting transported out of the Arctic. A Der Spiegel article just 2 weeks ago titled ”Feared Atlantic current is now weakening” suggests that this current is at its weakest level in 1800 years. What is it caused by? According to scientists, Der Spiegel says: As a cause for the change, scientists suspect climate change. The coincidence that this has happened during the warming of the last decades allows this to be the conclusion, they believe. But the knowledge about ocean currents still has many holes says Wallace Broecker of Columbia University in USA – a pioneer in ocean research.” Changes in the atmosphere controls the ocean currents? Right. And as usual, they’re sure – yet admit there are many holes in the knowledge and so they are not sure. Meanwhile, the ice keeps growing. http://notrickszone.com/2011/01/31/arctic-adds-2000-cubic-kilometers-of-ice-despite-reports-of-accelerating-ice-melt/

yes, ice coverage typically increases in winter, but volume is still way down. Again, with each consecutive post you indicate your lack of understanding of physics.

Scientist says Arctic getting colder
Warm North Atlantic Heating Arctic
Repeat of a negative Arctic Oscillation leads to warm Arctic, low sea ice extent
Arctic sea ice extent for December 2010 was the lowest in the satellite record for that month. These low ice conditions are linked to a strong negative phase of the Arctic Oscillation, similar to the situation that dominated the winter of 2009-2010.
Surface temperature anomalies for the period 17 December 2010 to 15 January 2011 show impressive warmth across the Canadian Arctic….
The largest anomalies here exceed 21°C (37.8°F) above average, which are very large values to be sustained for an entire month.
