sea surface temperatures.»
The global

the

for the first part of the
record)?
Now the NOAA data comes in and confirms the GISS data, and shows the http://www.ncdc.noaa.gov/oa/climate/research/2009/jun/global.html Global Highlights: Based on preliminary data, the globally averaged combined land and
