SH Sea Ice Data and Anomaly
Posted by Jeff Condon on December 14, 2008
Well everyone on earth probably knows about the plight of the polar bears looking for that last ice cube to stand on in the arctic. I bet under 1/10th of the people know that the southern hemisphere has increased in ice level. We have all heard that the increase at the south pole hasn’t compensated for the NH losses, how bad is it.
The slope of the increase in area is 0.02910 milion Km^2/yr. The shape of the annual signal is more sinusoidal than the NH and is shown below.
The SH area anomaly from the bootstrap algorithm by my calculation is.
Now lets look at southern hemisphere sea ice extent. Slope of the red line is 0.02602 million Km^2/year.
The shape of the annual extent signal
And then the Ice extent anomaly.
Well there you go. The SH is adding ice at nearly the same rate the NH is loosing ice. In the NH the area is decreasing by -0.02679 million Km^2/yr while the SH is increasing by 0.02910 million Km^2/yr.
To me that is an absolutely shocking set of slope numbers, I’m learning more every day.
