Sea Ice 2012
Posted by Jeff Id on January 28, 2012
I have reworked my sea ice code to account for leap years and to make it easier to read. It wasn’t a terribly easy process but it was useful. Here I will present some plots of sea ice trend as derived from the gridded satellite data. The purpose of this was to verify their accuracy and lay groundwork for future posts on sea ice.
Unfortunate statistically significant loss of ice during unprecedented death-spiral sea ice doom.
All of the graphs here have been taken from the NSIDC gridded data. Of all the government funded global warming groups I have corresponded with, these people are the best. The graphs shown are daily data with some linear interpolation for the earliest decade where data was missing. AR corrected c0nfidence intervals are reasonable but are getting close to 1 so don’t interpret them too closely. They also assume a normal distribution – which probably isn’t that bad of an assumption. Bottom line – look at them as an approximation. – – more people should write that.
Now for my signature sea ice plot. The global sea ice with an offset based on the average area of sea ice. The purpose of this plot is to explain that there is a heck of a lot of sea ice left on this “little blue marble” and that those who panic are in their own special class.
I will present the code for these plots soon. It is fairly complex, definitely has a C accent that would drive Mosher crazy, but does the job more accurately than anything I have previously produced.
