The mean temperatureof 75.1 for July 2010 on Blue Hill Massachusetts breaks the recordhottest month, previously set at 74.9 in July of 1952. This is notjust a July Record, this is for any month on record. Blue Hill Observatoryhas continuous weather data going back to 1885. So we can state withconfidence this is the hottest month here in Eastern Massachusetts inmore than 125 years.
One Hundred andTwenty Five Years! That is a lifetime and then some! But in a world ofrapidly changing climate, 125 years is a pin prick. So how important isthe record? Does this prove man-made climate change is real? Myconfidence is shaken, but not broken. I am still in the calm camp ofwhat I call rational meteorologists. We can look around the world andsee plenty of signs that we are experiencing natural cycles, and thatfor every hot record, we have a cold record. Winter 2010 in thesouthern Hemisphere is shockingly cold and snowy, for many there this is thecoldest and snowiest in a life time. Just three weeks ago a front formthe South Pole made it all the way to two degrees north of the equatorin Brazil, that is amazing. Snow accumulated in Bolivia, Brazil, and on theshores of Argentina. The amount of Ice at the South Pole is at historichighs. Closer, here in the USA, San Diego CA is experiencing a rathercold summer. Here is a Statement form National Weather Service in SanDiego.
RECORD LOW MAXIMUM TEMPERATURES FOR VARIOUS LOCATIONS WERE TIED OR
BROKEN ON 21 DAYS IN JULY. ON THE 8TH...SAN DIEGO TIED ITS ALL-TIME
RECORD LOW MAXIMUM TEMPERATURE FOR THE MONTH OF JULY WITH A HIGH
TEMPERATURE OF ONLY 64 DEGREES. THE LAST TIME THIS OCCURRED WAS IN
IN SAN DIEGO...THE AVERAGE HIGH TEMPERATURE FOR JULY WAS 69.4
DEGREES...THE 5TH LOWEST SINCE RECORDS BEGAN IN 1875 AND THE LOWEST
SINCE 1916. THE AVERAGE TEMPERATURE FOR JULY WAS 65.9 DEGREES...THE
14TH LOWEST ON RECORD.
In Russia the heat is on, 100 was recorded 'for the first time ever'. So why is San Diego so cold,
and here and abroad so hot?
Engines that drive the climate are multiple and complex.
But a simple view is that our Heat comes from the sun, and is stored in the Oceans.
The Pacific is the largest store, and is currently coming off an El Nino and
is in a cooling mode overall. The Atlantic Ocean however is in a warm cycle,
with plenty of energy available for warming continents (and fueling hurricanes).
In this cycle, naturally we can expect
continents adjacent to the Pacific to cool, while those near the Atlantic warm.
But watch out, the North Pole is having a cold summer,
with the least July ice melt in the last several years.
That may mean trouble (cold), for
us this winter.
Today is Camille's Anniversary of 200 mph into Mississippi .
And that was B4 Global Warming! Hopefully Colin is Kinder.
The National Hurricane Center is tracking huge Tropical Wave,
likely to become Colin and arrive near the southeastern US
Tuesday 10th or so.
Here in New England, the intermission of Hot & Stormy Summer 2010 will end Wednesday,
as Hot & Stormy returns.
Part two begins in few days, and we add hurricane threats to the Hot and Stormy Pattern.
