Scientists have discovered that the North Pole's average temperature year around at one time was 76 degrees Fahrenheit. Today it appears to be headed back that direction too. As it is now expected that ALL Arctic ice will melt out for a time within the next 20 or 30 years for the first time in recorded history since there have been humans with writing, memory or even hieroglyphics to record such things.

The last time the average temperature was an average of 76 degreees Fahrenheit year around or 24.444 etc. Celsius it took a whole lot of ferns growing from the North pole to the equator(which is one of the most efficient plants in converting carbon dioxide to oxygen) about 1 million years to bring us back to the temperatures we saw during the 19th and 20th century at the north pole.
