The "energy loss" of the Earth accumulates in the oceans

                 

Two years ago, scientists at the National Center for Atmospheric Research in Boulder, Colorado, published a study which found inconsistencies between satellite observations of heat on Earth, and measurements of ocean warming, increasing evidence that he had "lost energy "in the system on the planet.

Where does it go? Or, they wondered, is there an error in the monitoring of energy, so that it was absorbed and emitted by the sun back into space?

An international team of atmospheric scientists and oceanographers, led by Norman Loeb Center at NASA Langley in Hampton, Virginia, and Graeme Stephens of the Jet Propulsion Laboratory in Pasadena, California, began to investigate the mystery.

We used 10 years of data, ranging from 2001 to 2010 - from the databases of the center itself and the CERES instrument Langley (Experiment Radiant Energy System of the Earth) to measure changes in the net radiation balance in the upper atmosphere.

The CERES data were combined with estimates of heat content of Earth's oceans from three independent sources of ocean sensor.

Their analysis, summarized in a NASA-led study published January 22 in the journal Nature Geoscience, found that satellite measurements and ocean broad agreement, once the observational uncertainties are taken into account.

"One of the things we wanted to do was a more rigorous analysis of uncertainties," said Loeb. "When we did, we conclude that the energy lost in the system was not really supported with data. Our data show that Earth has been accumulating heat in the ocean at a rate of half watt per square meter, with no signs of a decline, "said Loeb. "This extra energy will eventually find its way back into the atmosphere and increasing temperatures on Earth."

Scientists generally agree that 90 percent of the excess heat associated with increased concentrations of greenhouse gases stored in the oceans of Earth. If released into the atmosphere, an accumulation of half watt of heat per square meter could increase global temperatures by more than 0.3 degrees Celsius.

Loeb said the results demonstrate the importance of using multiple metrics over time and demonstrate the need for continuous improvement in the way they measure the energy flows on Earth.

The scientific team from the National Center for Atmospheric Research measures inconsistencies between 2004 and 2009 from satellite observations of the heat balance of the Earth and measuring the rate of heating of the upper ocean. They said that the inconsistencies were proof that he had "lost energy".
