It's gone away somewhere, that's for sure.
New research from satellite man Dr Roy Spencer, principal research scientist at the University of Alabama in Huntsville and maintainer of the UAH temperature record, sheds some light on climate science's "missing heat" mystery.
Climate models have predicted more warming than the instruments have measured – leading to various explanations. One paper claims the heat is real
, but it's deep in the oceans, and there's no mystery. NASA's James Hansen – in a private paper released earlier this year – disagrees. Hansen says (PDF/1.5MB
) the heat isn't in the oceans at all, but simply hasn't manifested itself in the form of global warming, because of man-made and natural aerosols. The models "mix heat too efficiently into the deep ocean and as a result underestimate the negative forcing by human-made aerosols," says the Yoda of Catastrophic Man-made Global Warming.
Earlier this month, a team led by an economist pronounced that aerosol emissions from Chinese coal stations were "consistent with
" Yoda's theory.
Spencer's work, published (pdf
) in the journal Remote Sensing, concludes that more energy is radiated back to space than previously thought, and it is released earlier, too. Spencer looked at warming events (he used Hadley's temperature record and the CERES energy sensor data from NASA's Terra satellites) and compared the empirical evidence against six climate models.
