This Arctic
Sea Ice Time Plot shown below is updated daily by the National Snow
and Ice Data Center
(NSIDC) in Boulder CO.
From Sweden, we have Arctic
Regional Ocean Observing System (Arctic ROOS) The fact that
2007 data is included in their average line means it is a lower than
the 1979-2000 mean at NSIDC.
University of Alaska Fairbanks has the International
Arctic Research Center, using data from the Japan Aerospace Exploration
Agency. This plot shows the seven most recent years.
A prediction of the Arctic Oscillation is made by NOAA A negative Arctic
Oscillation level generally means colder at the north pole.
Sea Levels
On NASA’s Global Climate
Change Key Indicators page, it is odd that they do not
present
their own most current Jason 1 satellite data; their plot below stops
around Oct. 2007.
Sea level data from Jason 1 and Jason 2 is released by
the French AVISO
agency. Here is one of their plots.
But the sea
level trend according to the University
Of Colorado, global sea level has scarcely risen since 2005.
Both of these plots are of the same Jason 1 and Jason 2 data, why are
they so different now.
Here is a big
time line
If the sea level is starting to drop, as of about two years ago,
after 20,000 years of rising, that would be profound news...
Effects
of cosmic ray flux (CRF) on clouds and precipitation
Henrik
Svensmark is a physicist at the Danish National Space Center
in
Copenhagen who studies the effects of cosmic rays on cloud formation.
The Sun comes in to the picture in this process as its magnetic field
has an influence on the amount of cosmic rays hitting the earth.
"During the last 100 years cosmic rays became scarcer because
unusually vigorous action by the Sun batted away many of them. Fewer
cosmic rays meant fewer clouds--and a warmer world."

Israeli/American physics professor. In 2002, Shaviv hypothesized that
passages through the Milky Way's spiral arms appear to have been the
cause behind the major ice-ages over the past billion years. Nir maintains the site ScienceBits,

Spiral Arms and Ice-Age Epochs and the Cosmic Ray Connection.
