'What is the reason for the lack of warming observed at the surface of the Earth since about 1997? Many causes have been proposed, and with increasing frequency, but most only represent partial explanations.' 'The ocean heat content is not behaving as some expected. (The past 10 years the oceans) shows no warming in upper most layers. If the heat is there, it must be deeper, far harder to detect. And possibly locked away for thousands of years.'
Easterbrook: 'It really isn’t a mystery at all, it was predicted in 1999 on the basis of consistent, recurring patterns of the Pacific Decadal Oscillation (PDO) and Atlantic Multidecadal Oscillation (AMO) and global climate.'
Study's conclusion: 'The decaying solar activity makes the recently recorded global temperatures flatten out and thus disguises the real climate development. With a steady level of cycle-average solar activity the global temperatures would have shown a steady rise from 1980 to present (2013) in agreement with the increasing atmospheric concentrations of green-house gasses, primarily carbon dioxide and methane , and not the levelling-off actually observed since 2001.'
Meteorologist Anthony Watts comment: Despite the fact that 'there are numerous claims that solar activity (and the slight increase in TSI seen in the last 30 years) can’t explain the global warming we’ve seen, but yet somehow the recent period of low solar activity can explain the pause'
'The heat is still coming in, but it appears to have gone into the deep ocean and, frustratingly, we do not have the instruments to measure there,' said Professor Ted Shepherd of Reading University. 'Global warming has certainly not gone away.'
