The North Pole won't melt this year.

All the media hype notwithstanding, this year's arctic ice isn't going to disappear.  In fact, there is today more ice in the arctic than this day last year.  In fact, there is almost 1 million square kilometers more.  In fact, there is more ice today than there was on this date in 2006 and in 2005.  There is more melting to be done but we are, this week, in the period of greatest melt and 2007 is losing ground to 2007.

The loss of ice over the past couple of years appears to have been more to do with changes in wind patterns than with changes in temperature.  Arctic air temperatures have not been unusually warm and ocean temperatures globally have cooled somewhat in the past few years. It appears that the winds pushed more of the ice than usual past Greenland into warmer waters where it melted away.  This year's wind patterns are apparently more benign in that regard.

This past winter showed the fastest and most extensive sea ice recovery every documented. Media outlets have been reporting that since this year's ice was new ice, it would be easier to melt.  That is because first-year ice has a higher salt water content and melts at a lower temperature. Multi-year "old" ice is also more compressed and denser causing it to melt more slowly at a given temperature.  It seems this year's ice is thicker than previously thought and this summer has not been as sunny in the arctic resulting in lower melt rates than predicted.

The major media can be expected to pick up on this story and widely report this year's great arctic ice recovery ... well ... probably when we see Satan on skis.

173rd Airborne Brigade -- American Heroes

On 13 July 2008, 45 paratroopers from the 173rd Airborne Brigade along with 25 Afghan soldiers defeated a coordinated attack by 500 Taliban in Kunar province Afghanistan. Nine of the paratroopers were killed and 15 were wounded leaving 21 paratroopers and 21 Afghan soldiers to fight off an attack of 500 enemy.  Not only did they manage to kill dozens of the enemy, they also succeeded in repelling the assault. 

Ladies and gentlemen, this generation of Americans have stood and answered the call with amazing heroism.  Words fail me in my attempt to describe the pride and the gratitude in my heart.  The 173rd is based in Italy.  There will be no homecoming here in the US.  But if any unit in this war deserved a parade, it would be those of the 173rd Airborne Brigade.  What an amazing group of young Americans!

Today's Employment Numbers

Well, first of all, it has been a long time since I wrote a blog entry here.  Life has been hectic with the tragic loss of a spouse, suddenly being a single parent of two elementary schoolers, and changing jobs in the middle of that adjustment.  But we adapt and life goes on. Now to blogging!

I thought something was fishy with the employment numbers released today when all I heard on the radio on my way home from work was that the US "lost" some 60,000 jobs but no mention was made of the unemployment rate.  So I went and looked it up a few minutes ago and as I suspected, the unemployment rate was unchanged from last month.  How, you might ask, can the economy "lose" 60,000 jobs and the employment rate remain unchanged?  Easy; companies are cutting unfilled positions.  They are eliminating jobs that they have been unable to fill.  And this phenomenon is going to become more common as more of the "baby boom" generation retires.  We are going to see a period where workers will be leaving the workforce at a faster pace than people are entering.  In other words, the reverse of the situation we saw in the 1960's and 1970's when we had more people entering the workforce than the economy could absorb and saw rising unemployment.

All of the reports seemed to be grasping for bad news.  They were along the lines of "while unemployment remained steady at 5.5%, May's rate jumped by the largest amount in ...". In other words, they had to reach back a couple of months and regurgitate May's bad news.

The perceptions of what constitutes a good economy and what constitutes a bad economy were formed back when we had the largest single generation of Americans in history in the job market.  That generation is now on its way to retirement.  A 5.5% unemployment rate is right at the edge of "optimal" unemployment rates.  4.5% to 5.5% is considered the desired range that is sustainable over time.  The double digit unemployment rates of the late 1970's is apparently gone from the American memory.

The loss of jobs when an economy is losing workers is actually a GOOD thing.  You do not want a situation where unemployment drops much below 4.5% because then there aren't enough workers "between jobs" for business to hire new workers simply to replace ones that leave over the normal course of career advancement.  Below 4% you get into a situation where businesses begin to "bid up" salaries in order to attract what labor you can get and that labor is probably less qualified because at that point, all the people who are sharp at what they do are already working.  That was the situation in Silicon Valley during the dot-com bubble.  Companies could not find workers at any price and the salaries being paid to even entry-level employees were through the roof.  That situation is not sustainable over the long term for an economy as a whole.  What actually happens is that companies start trading workers around as they bid salaries up.

So today's unemployment numbers really aren't such bad news at all.  Business cut 60,000 jobs but they were either unfilled positions or a corresponding number of people who had been out of work in May had been able to start new jobs or a combination of both.  The place where I work added two new job openings in the past month and we have two positions to fill due to people changing jobs on their own.

The retirement of the baby boom is going to challenge all the notions we have about economics.  We are going to see people retiring in droves within the next few years.  Businesses are going to have a hard time finding the labor to fill those positions.

Happy Independence Day!
