La verdad es que se las trae...
"Whereas satellite instruments indicate that greenhouse gases are continuing to trap more solar energy, or heat, scientists since 2003 have been unable to determine where much of that heat is going.
Satellite sensors show that the amount of greenhouse-trapped solar energy, or heat, has risen over recent years. But in the past decade, there has been a growing divergence between the satellite readings and ocean observations that indicate the build-up of heat is slowing. This "missing" heat could, in part, be the result of instrument error or incorrect data processing, but much of it may be going into the deep ocean or elsewhere on Earth that is beyond the reach of current sensors. This graph shows simplified estimates of the measurements of heat. (Courtesy Science.)"

"Much of the missing heat may be in the ocean. Some heat increase can be detected between depths of 3,000 and 6,500 feet (about 1,000 to 2,000 meters), but more heat may be deeper still beyond the reach of ocean sensors.
Trenberth and Fasullo call for additional ocean sensors, along with more systematic data analysis and new approaches to calibrating satellite instruments, to help resolve the mystery. The Argo profiling floats that researchers began deploying in 2000 to measure ocean temperatures, for example, are separated by about 185 miles (300 kilometers) and take readings only about once every 10 days from a depth of about 6,500 feet (2,000 meters) up to the surface. Plans are underway to have a subset of these floats go to greater depths.
“Global warming at its heart is driven by an imbalance of energy: more solar energy is entering the atmosphere than leaving it,” Fasullo says. “Our concern is that we aren’t able to entirely monitor or understand the imbalance. This reveals a glaring hole in our ability to observe the build-up of heat in our climate system.”"
