    Despite documented increased in CO2  emissions, not all of it has ended up in the  atmosphere.  Why? Despite documented increase in CO2  levels, global temperatures haven’t risen  as much as earlier models predicted.  Why?

The oceans, which cover  more than 70% of the  earth’s surface, play a  fundamental and complex  role in regulating climate.   The oceans absorb huge  amounts of solar energy. Ocean currents transport this  heat from the equator toward  the Poles.  Future climate changes— whether natural or human- induced—will also be  strongly influenced by the  ocean.

SST data can be used to  study annual shifts in ocean  currents and temperatures.  These changes in ocean  conditions are  interconnected with seasonal  weather patterns such as  monsoons and droughts.  SST data are also crucial to  understanding periodic  phenomena like El Niño and  long-term climate shifts  attributable to global  warming.  Measurements of the temperature of the sea surface today, taken by satellite.
