Here is the real condition of Arctic sea ice and it's not good:
At Start of 2015 Melt Season, Arctic Sea Ice is in a Terrible State
...In the extent measure we find that for the past month running we have been at or near new record lows. Over recent days, consistent with the strong surge of polar heat amplification, extent values have again plummeted past previous record low values. Dropping by more than 50,000 square kilometers for each day in the April 6-8 timeframe, the melt rate is exceedingly steep for this time of year. With April 8 achieving a new record low extent of 14,073,000 square kilometers 95,000 square kilometers below the previous record low of 14,168,000 set in 2006...
National Snow and ICe Data Center: A Double Dip
...Arctic sea ice extent for March 2015 averaged 14.39 million square kilometers (5.56 million square miles). This is the lowest March ice extent in the satellite record. It is 1.13 million square kilometers (436,000 square miles) below the 1981 to 2010 long-term average of 15.52 million square kilometers (6.00 million square miles). It is also 60,000 square kilometers (23,000 square miles) below the previous record low for the month observed in 2006...

Any rational person can now see than an exponential doubling period has been established
