Unprecedented trade wind strength is shifting global warming to the oceans, but for how much longer?

RATE THIS! +16

Research looking at the effects of Pacific Ocean cycles has been gradually piecing together the puzzle explaining why the rise of global surface temperatures has slowed over the past 10 to 15 years.  
 
A new study adds yet another piece to the puzzle by examining the influence of Pacific trade winds.
 
While the rate of surface temperature warming has slowed in recent years, several studies have shown that the warming of the planet as a whole has not.  This suggests that the slowed surface warming is not due as much to external factors like decreased solar activity or more pollutants in the atmosphere blocking sunlight, but more due to internal factors shifting the heat into the oceans.
 
 In particular, the rate at which the deep oceans have warmed over the past 10 to 15 years is unprecedented in the past half century.
 
Research led by Masahiro Watanabe of the Japanese Atmosphere and Ocean Research Institute suggests this is mainly due to more efficient transfer of heat to the deep oceans. Consistent with model simulations led by Gerald Meehl, Watanabe finds that we sometimes expect "hiatus decades" to occur, when surface air temperatures don't warm because more heat is transferred to the deep ocean layers.
 
 A paper published last year by Yu Kosaka and Shang-Ping Xie from the Scripps Institution of Oceanography found that accounting for the changes in Pacific Ocean surface temperatures allowed their model to reproduce the slowed global surface warming over the past 10 to 15 years.  However, the mechanism causing these Pacific Ocean changes has remained elusive.

The evidence of global warning and devastations that are already happening and are likely to increase Is becoming too huge to ignore - something has to be done Reply

The next important thing would be to start explaining the cause of the dramatic, unprecedented trade wind acceleration. Reply

The message is very clear: "the current hiatus offers no comfort - we are just seeing another pause in [surface] warming before the next inevitable rise in global temperatures." Reply

The question remains: what would convince people hat the predictions are correct?
Is there any scenario short of the extinction of the human race which everyone would start to regard as enough?

1:24 AMDo you also think people who have a hobby of reenacting confederate Civil War soldiers are out of line?? Maybe this isn't so copedicatml.Look at it from a different angle and you will see that some peoplejust enjoy the History of it all.Don't be so offended by either group. Just learn what you can from it especially if they depict it as accurately and sincerely as possible.Aloha from Makaiip.s. Maybe you should check with the President of the Anons; a more moderate rant in the New Year would be appreciated. Reply
