WARMING INTERRUPTUS: CAUSES FOR THE PAUSE – ‘There are clearly more putative causes than can possibly be the case’

…Climate Depot Analysis: ‘There have been at least 10 separate explanations for the standstill in global warming’ – 1) Low Solar Activity; 2) Oceans Ate Warming; 3) Chinese Coal Use; 4) Montreal Protocol; 5) Readjusted past temps to claim ‘pause’ never existed 6) Volcanoes 7) Decline in Water Vapor 8) Pacific trade winds 9) ‘Coincidence’ 10) ‘Stadium Waves’
10) Update Feb. 28, 2014 via WattsUpWithThat.com: Stadium Waves. Wyatt and Curry 2013. ‘Stadium waves’ could explain lull in global warming. ‘The stadium wave periodically enhances or dampens the trend of long-term rising temperatures, which may explain the recent hiatus in rising global surface temperatures’

Climate Depot Analysis: ‘There have been at least nine ten separate explanations for the standstill in global warming’ – 1) Low Solar Activity; 2) Oceans Ate Warming; 3) Chinese Coal Use; 4) Montreal Protocol; 5) Readjusted past temps to claim ‘pause’ never existed 6) Volcanoes 7) Decline in Water Vapor 8) Pacific Trade Winds 9) ’Stadium Waves’ 10) ‘Coincidence’
Welcome to the world of ‘settled science’. With the latest study now placing blame on Sun for the ‘pause’ in global temperatures, that means there have been at least five seven eight nine ten separate explanations to attempt to explain the standstill in global warming. There is seemingly no end to warmists’ attempts to explain the global warming standstill.
Update Feb. 28, 2014: Der Spiegel On 15-Year Pause: ‘Biggest Mystery In Climate Science’: ‘Climate models had never expected the pause: Only 3 of 114 climate simulations were able to reproduce the trend of the past years, the IPCC concludes in its latest report. The reason for the deviation between models and observations is unclear.’
As blogger Tom Nelson noted: ‘If we don’t understand lack of warming post-1998, how can we understand warming pre-1998?’

3) Chinese coal caused the ‘pause’, published in the proceedings of the National Academy of Science. The study blamed Chinese coal use for the lack of global warming. Global warming proponents essentially claimed that coal use is saving us from dangerous global warming

New paper finds current climate models are ‘unable to reproduce present or future climate accurately’

More problems for the models: An article published today in Nature says “a new player on the scene” called “internal lee waves” are “a player in ocean dynamics that may make an important contribution to deep-ocean mixing…Climate models that do not represent this mixing appropriately will be unable to reproduce present or future climate accurately.” According to the article, current IPCC climate models do not include this deep-ocean mixing from lee waves, which “warrant serious consideration for inclusion in the next generation of climate models.”
Excerpts:
Internal lee waves are a player in ocean dynamics that may make an important contribution to deep-ocean mixing. They warrant serious consideration for inclusion in the next generation of climate models.
Turbulent mixing in the ocean interior plays a crucial part in driving downward transport of heat and dissolved greenhouse gases and upward transport of biologically essential nutrients. It also ultimately supplies the deep ocean with the energy that drives a global network of currents known as the meridional overturning circulation. Climate models that do not represent this mixing appropriately will be unable to reproduce present or future climate accurately.
Many previous studies have focused on the breaking internal waves that are driven by tides and winds as the dominant source of that turbulence. In a paper published in Geophysical Research Letters, Nikurashin and Ferrari2 describe a previously under- appreciated dynamic mechanism — internal lee waves — that may significantly contribute to mixing in the deep ocean. Away from the direct influence of surface forcing, most turbulent mixing in the ocean interior is driven by breaking internal gravity waves3. These propagate along and across den- sity interfaces within the ocean, similar to the interfacial waves you might see between oil and vinegar in a glass or even between coffee and milk in a well-made cappuccino. Compared with the more familiar surface waves, internal waves are much slower, with periods of hours instead of seconds.
Their breaking is in many ways analogous to that of surface waves on the beach, albeit in a slow-motion, larger-than-life way — the wave height may reach tens or even hundreds of metres3. But unlike waves at the beach (which lose all of their energy to heat or sound with each thunderous crash), some of the energy lost by breaking internal waves increases the …
