Two years ago, scientists at Colorado's National Centre for Atmospheric Research released a report claiming that satellite measurements of earth's heat didn't match up to ocean warming.
Now, Nasa has found the 'missing energy' - slowly warming up the sea.
Researchers had wondered, was something wrong with the way researchers tracked energy as it was absorbed from the sun and emitted back into space?
An international team of atmospheric scientists and oceanographers including Graeme Stephens of Nasa's Jet Propulsion Laboratory in Pasadena, California set out to investigate the mystery.
They used 10 years of data -- spanning 2001 to 2010 -- from Nasa's orbiting Clouds and the Earth's Radiant Energy System Experiment (CERES) instruments to measure changes in the net radiation balance at the top of Earth's atmosphere. Read More
