2009 Year-to-date Land and Sea Temperatures

I've heard the climate change skeptics are excited that there has been a cooling trend that might appear to call into doubt forecasts of global warming. Not sure where they are getting their data, but the National Oceanic and Atmospheric Administration (NOAA) recently released it's July 2009 State of the Climate Global Analysis. There does not appear to be much of a cooling trend. If you look at their graph reproduced above, it shows the dramatic warming recorded in the combined global sea surface and land surface temperatures over the last 130 years.

They have also produced a graph separating the sea surface and land surface temperature record over the same 1880 to 2009 time period. You can see in the image below that both ocean and land surfaces show this warming trend. I wish there were a cooling trend overall, but it just isn't there.

The entire July 2009 report (including the two graphs above) may be found at the following link:
