No, it's not a mystery. The heat has gone into the oceans. The recent article DB posted speaks to this. There is more heat going in the oceans then we realized. There may also have been some reduction in solar due to more stratospheric aerosols mostly from dirty coal burning in China and India.
Please stop posting any misinformation that contradicts one of the authoritative sources of climate information in the world.
Oceans Hid the Heat and Slowed Pace of Global Warming The Atlantic and Southern oceans may be responsible for the slowdown in the acceleration of global warming—but not for long Aug 22, 2014 |By Niina Heikkinen and ClimateWire Researchers use Argo floats (pictured) to help collect data.

The trend is likely connected to roughly 30-year global warming and cooling cycles, according to researchers. The study could put to rest a long-standing debate among scientists about why air temperature rise had halted after a period of rapid increases at the end of the 20th century. "We weren't surprised by the results, but this is the first time we've been able to prove it," said Ka-Kit Tung, a co-author of the study and adjunct professor of applied mathematics at the University of Washington. Tung collaborated with Xianyao Chen of the Ocean University of China, a visiting professor at UW last year. Their study was published today in the journal Science. more . . . and http://www.elitetrader.com/et/index.php?threads/climate-change.286732/page-13#post-4034029
