NORTH POLE AND SOUTH POLE ICE EXTENT

The image above from Arctic Sea Ice Extent, ijis.iarc.uaf.edu is a typical exemple of what all who study Mathematical Statistics are taught not to use. It’s an image not showing the correct proportions. For those who can read curves that might not be an issue. For those who can’t it is.
SEASONAL UPS AND DOWNS IN ICE EXTENT
What’s is important to understand reading the curves is the simple fact that Pole Ice Extent in North Pole as well as South Pole depend on season. Each year the summer ‘heat’ warms up the air and the surface so the Ice Extent decline. Each year the winter ‘colder temperatures’ makes the Ice Extent incline.
IN ACCURATE PRESENTATION OF A CURVE
Please note that the curves not presenting all facts from actual readings from 1980’s up to now. From Theories of Science view this is an red alert at once.
Neither does is it possible to read from image if the reading of a certain day is made at same hour each day or if it’s an average figure counted from max minus min values or if it’s the max or min value of the day. From Theories of Science view this is an red alert at once.
Also please note that the figures, no matter how they are measured calculated and presented, are from readings made by satellites. What can be measured from satellites are reflexion of ice extent. Not actual extent due to the fact that there are large areas in Arctic as well as Antarctic where there during summertime (in Antarctic when it’s winter in Arctic) often exists melted water up to 20 cm over ice no matter if it’s thin ice or several metre thick sea ice. From Theories of Science view this is an red alert!
Same goes for temperature measurements made by satellites. You can’t get temperatures 2 meters above surface nor can you get the actual figures from under the Ice sheet. All correct figures also needs to be taken at same GPS-point no matter when.
If you are accurate you need to do the reading at same time every day. If you don’t or if you try to “correct” figures, well that’s no Science involved at all. In Theories of Science this is one of the worst fallacies. A circle proof can never ever prove anything of value. That’s one thing every scholar, scientist or otherwise should have learnt before writing a Master thesis…..
Please observe this:
Extent for North Pole Ice 31 december 2013 12.341.252 km2
Compare this with the Area of United States of America approx 9.830.000 km2
This gives us the fact that the Sea Ice Extent in North Pole in 31 december 2013 was more than 125 % of US total land area..
Please notice that the estimated figures for Ice Bear north the pole circle is 20-22,000…. this means that each Ice Bear have approximated 560 km2 each to walk on without having to meet an other Ice Bear.
That might not seem a lot when using the scale above. But please remember that the area for New York City is 1.213 km2 which gives a figure af close to half the area of New York City for each individual Ice Bear to walk on.
So Greenpeace and WWF ought to rethink the need for ‘saving the Ice Bears’ and to present where on Earth the collected money has been used!
