GISS tells us that it was the hottest May on record. Just looking at that map makes me perspire. It must be wicked hot at the North Pole!
But wait a minute! The DMI record doesn’t look so hot in the Arctic.
What could be wrong? Could it be the fact that GISS has almost no coverage in the Arctic? We often hear the question”what if CO2 were pink?” Answer : it would still be almost invisible at 0.0004 concentration.
Now, let’s turn that around and see what GISS coverage holes would like if they were pink.
Shocking pink, that is. GISS is claiming a global temperature record based largely on the Arctic – in which they have less than 10% coverage. Hansen explains the growing gap between GISS and Had-Crut as being due to the fact that GISS has better Arctic coverage.
Judge for yourself.
GISS has 2010 at #1. Had-Crut has 2010 at #4. Thanks to GISS’ extensive Arctic coverage.

“David L. Here is what the holes look like as transparent”
Thanks for posting so quickly! Even though transparent is “cool looking” the pink is more striking!
NASA GISS had a huge 11 degree mistake in their data for March 2010 in Sodankylä, Finland. They claimed, that the mean temperature was +2C, which was ridicilous. They “corrected” the problem by deleting the data and extrapolating. The huge red spot on Finland disappeared and changed to blue. Funny thing was, that one wrong measurement like this turned almost the whole Scandinavia red.
Then two months went and the same idiotic mistake reappeared. Weirdly enough, this happened at the same time when NASA claimed, that the last 12 months have been the warmest ever. No wonder, if your data is 10C off.
Well, the problem is corrected again, but I bet the same mistake will reappear again later this year. They don’t treat the real problem and only treat the symptoms. So keep your eyes open on NASA GISS measurements for Finland in 2010.
Steve Goddard says: “Concentration is a dimensionless number. It has no units.”
What?? Since when? Concentration always has units: 0.0004 g CO2/g air, or if done by volume 0.0004 L CO2/L air. The grams and L do not cancel as they refer to different species.
This is why we use PPM or PPB as concentration units for a ratios of masses.
Continuing still about that 10C huge mistake in Sodankylä. Any red spots on that map should be double checked. Actually, nothing on that map should be believed without scrutiny as NASA obviously does no quality control on their data.
GISS did lose most of Africa and the World Cup, but being part of NASA they did discover something remarkable about the football stadium in Johannesburg.
Nice propaganda job Steve, as always. Opening with the subtle ‘trick’ of comparing the GISS monthly anomaly with the DMI daily temperature, classic ‘apples to oranges’. By the way Steve how many stations are used to compile the DMI temperature, how big are their holes? Since you persist in showing your comparison with UAH why not do it correctly and show that they have no coverage north of 82.5ºN?
Hansen’s Arctic hole is represented by the color assigned a greater than +5° anomaly (from the bar key below). I know many alarmists (including politicians) who would simply look at the image an conclude that Arctic warming is out of control without even the slightest understanding that the +5° end of the scale actually represents a lack of data and not out-of-control warming. How does Hansen do this with a straight face, let alone scientific integrity?
AG Foster – Thanks for the explanation. CO2 is in parts per unit volume.
It’s always amazed me that people do not see the disconnect between claiming that different areas of the world can be hotter or colder, all at the same time, because of weather, and then claiming that anyone can get a global temperature by adjusting, guesstimating, averaging, fudging the very few temperature stations they have. They even claim that they know exactly how much heat has been added to their stations over the years by people developing the land around them, and can accurately adjust for that too.
and then taking it to the next level by claiming they can get a trend from that………
and that accurate temperatures do not matter, it’s the trend.
Looks like they can just about claim any temperature or trend at any time and get away with it……
Benjamin Said –
“Funny to see such a great correlation between no data and warming.
Maybe the best way to fight against global warming is by adding thermometers ? :)”
It fits the predetermined narrative though doesn’t it? It is the only thing that it could be. Wherever there is no data, it must be warmer. After all, it is worse than we thought.
Concentration could also be expressed as .04% of the atmosphere, I believe? Not much. Does this not differ by altitude? Do the different gasses which make up our atmosphere not concentrate at different elevations? What effect does that have on their greenhouse effect?
The notion that a trace component like CO2 can have only a negligible effect due to its ultra-low concentration is an incorrect one, and I find it odd that it is perpetuated here. The absorption by CO2 of outgoing longwave thermal radiation is based on the absorptivity coefficient of the gas and on the optical path length. The actual absorption of radiation by atmospheric CO2 in its frequency range is therefore quite large.
Steve Goddard: What month are you presenting in the second animation?
These temp records are just wrong. It is nearly a record winter in Australia/NZ yet the anomaly map shows positive. The positive anomaly is manufactured and in fact we are having serious cooling. Worst spring in 15 years in the Pacific NW. Seriously.
Henry chance says: “So the GISS tells us it was very hot in areas they took no readings. The old term for this was cheating.”
But it’s not that they “took no readings.” GISS deletes Sea Surface Temperature data, which varies less than Land Surface Temperatures, and extends Land Surface Temperature data out over the oceans. Refer to:

Question for Steve (or others).
When visiting the DMI site (http://ocean.dmi.dk/arctic/meant80n.uk.php), their explanation of daily mean temperature is not clear, to me at least. Is the daily “mean” red curve actual measured temps or some type of estimate (extrapolations?)? Does the green curve represent the daily average of actual average temps between 1958 and 2002, or is it some type of average of estimates?
If these indeed are temperature estimates, how is their estimation process different from GISS?
Per YouTube pic above, it ought’a be pale green. Then Good Ol’Mother Earth would look like a Do-Nut, a KrispyKreme Do-Nut!
Wasn’t it Hansen that claimed only a small number of thermometers are necessary to measure “global” warming? Why then does GISS need the Arctic?
Global warming is neither.
Owen, based upon the amount of energy entering the atmosphere and the amount of energy leaving the atmosphere, the absorbtion of CO2 is actually pretty darn insignificant at the current concentration.
The GISS folks should pay attention to what is actually happening on the ground, verses trying to confirm their bias toward global warming by force fitting heat into the Arctic. Too many organizations are trying to force the data to prove some kind of climate change model rather than sticking to actual observational data or perhaps they might say: “Huh, I don’t know if the data supports global climate trends.”
It has been cool and wet in Western Canada this year. The Canadian Wheat Board says that over 5 million hectares (12.3 million acres) are too wet to seed or are underwater in the Western Canadian Prairies – the wettest May and June in 40 years. The weather has, in a word, sucked. Maybe we are in a cool wet cycle, but we are not where the large population is in North America. It has been warm and humid in central Canada where the air from Gulf of Mexico air travels to. Coincidentally, that’s where the voters are so, voila! “Global Warming!” The climate seems more like “global schizophrenia” to the casual observer.
Did you see on the news of all those “football” fans in Argentina watching games in fans parks in the rain? Looks like typical fall weather there.
“”Owen says:

Owen, if you could answer a few questions for me, that might make it clearer and easier for me to understand.
In percentages:
1. How much atmosphere is CO2?
2. How much of that CO2 is man made?
3. How much of that man made CO2 can we possibly reduce?
4. If temperatures rising is a natural event and not something man-made, how much higher will CO2 naturally rise?
UAH NoPol anomaly for May is +2.51
RSS anomlay map (click on anomaly) here
http://www.remss.com/msu/msu_data_monthly.html?channel=tlt
shows arctic regions up to 4 deg warmer than 1979-1998 mean.
GISS arctic temperatures are perfectly consistent with satellite measurements.
The Mercator projection doesn’t hurt them either. Vast swaths of land and sea that don’t actually exist, are even now, roasting at an imaginary temperature.
Bob,
The GISS and HadCrut maps in the second animation were taken from Hansen’s paper
http://data.giss.nasa.gov/gistemp/paper/gistemp2010_draft0319.pdf
Figure 12. I believe it represents the entire year 2005.
Steve, that hot pink is a stroke of genius! It’s the perfect candidate for a new international symbol meaning ‘no information’, ‘made up information’ and ‘general bull[snip]’. It certainly sums up the GISS situation perfectly without needing a word of further explanation.
