May is here. It is one of the dryer months for Northerm Arizona. This May isn’t looking much different. It should be dry and nice for the most part. I don’t see any big drivers for warmer than normal temps.

But, what about sea ice. If you remember a couple years back, there were great expectations of the North Pole being ice-free. Well, that doesn’t seem to be in the cards for now. Here are a couple charts that tell a diffferent story. Northern Hemisphere Sea Ice did recede drastically a few years back. But, it is currently the highest coverage since 2002 at the start of May.

However, the departure from average for 1979 until now is still negative, but moving in a growth direction:

One more consideration is the Southern Hemisphere Sea Ice, where it is above average and growing:

Finally, overall, Global Sea Ice coverage is above average: Granted, recent levels have been below average:

So, shouldn’t the mainstream media give us a general update? If this trend continues, it might snow in London, or Lousiana, or, maybe just maybe we will see two back to back seasons where we can skate on Lake Mary, south of Flagstaff. Oh wait those things already happened.
