[Vision2020] US Cool Spring:Global Land Spring Temperatures 3rd Warmest, March Warmest On Record

[Ted Moffett]

The US overall and the Northwest had a cooler Spring, as described at NOAA
URLs below:

However, globally Spring was the seventh warmest on record (combined land
and ocean), with the land temperature the third warmest in record.  One
unusual event was the Eurasia swing from a record snow cover, to record low
snow cover, after a very warm March.  Globally, March land
temperatures, were the warmest March on record, as NOAA URL below describes:

http://www.noaanews.noaa.gov/stories2008/20080417_marchstats.html

 The global land surface temperature was the warmest on record for March,
3.3°F above the 20th century mean of 40.8°F. Temperatures more than 8°F
above average covered much of the Asian continent. Two months after the
greatest January snow cover extent on record on the Eurasian continent, the
unusually warm temperatures led to rapid snow melt, and March snow cover
extent on the Eurasian continent was the lowest on record.

The global Spring temperature information is at URL below:

http://www.noaanews.noaa.gov/stories2008/20080613_springtemp.html

 The combined global land and ocean surface temperature for spring 2008 was
0.94 degrees F above the 20th century mean of 56.7 degrees F and ranked
seventh warmest based on the 1880-2008 record.
The global land surface temperature for spring was 1.87 degrees F above the
20th century mean of 46.4 degrees F and tied with 2000 as third warmest.
--------------
An increase in the frequency of record precipitation events (US Midwest as I
write, for example) is one major prediction of climate change models, that
include the climate forcing of human greenhouse gas emissions (CO2, CH4,
NO2, etc.), and this includes record snowfall events.  Some speculate this
will slow or stop the rise in oceans from Greenland and Antarctica ice sheet
melt, because the increased snowfall in the interiors may replace the H2O as
fast as it melts on the edges.
