21 Apr 09 - Paul Stanko of NOAA writes meteorologist
Anthony Watts to tell him of an interesting development in his tracking
of the International Sunspot Number (ISN).
Paul writes:
My running mean of the International Sunspot Number for 2009
just dipped below 1.00.
For anything comparable you now need
to go back before 1913
(which scored a 1.43) which could mean
we’re now competing
directly with the Dalton Minimum.
Just in case you’d like another tidbit, here is something that puts
our 20 to 30 day spotless
runs in perspective… the mother of all
spotless runs (in the
heart of the Maunder Minimum, of course!)
was from October 15, 1661
to August 2, 1671. It totaled 3579
consecutive spotless
days, all of which had obs.
To say that that we in interesting times is a huge understatement.
We are about to enter a
Grand Minimum, which in the past have
produced a cooler planet,
while our government is preparing for
run-away global warming.
Who could have predicted this stupidity?
