[Vision2020] March 2010: NOAA: Global Temps Hottest March on Record: World's Oceans Set March Record Warmth

[Ted Moffett]

The Earth's oceans are 70 percent of total global surface area; and the US,
including Alaska, Hawaii, and the lakes and rivers of US territory, are a
mere 1.9 percent of total global surface area.  No one I have asked to
estimate the percent of US area of total global surface area has given the
correct answer.  All responses have indicated a much higher percentage of
the US share of total global surface area.  It appears US citizens somewhere
acquired the impression their nation is much bigger than it actually is...

Global Temps Push Last Month to Hottest March on Record

April 15, 2010
The world’s combined global land and ocean surface temperature made last
month the warmest March on record, according to NOAA. Taken separately,
average ocean temperatures were the warmest for any March and the global
land surface was the fourth warmest for any March on record. Additionally,
the planet has seen the fourth warmest January – March period on record.

Temperature anomaly is the *difference from average*, which gives a more
accurate picture of temperature change. In calculating average regional
temperatures, factors like station location or elevation affect the data,
but those factors are less critical when looking at the difference from the
average.
