Most word of world warming focal point on the temperature of the line at the Earth ’s Earth’s surface , where over the past decade thawing has slow up . This has result in lead astray declarations that global warming has " paused . " However , go bad to moot the heating of the oceans miss the bulk of orbicular warming .
Perception of climate change may be influenced by the frequency that climate-science words appear in the popular literature.
world-wide thaw has n’t paused , it ’s accelerating , specially in the oceans , according toa new studypublished online in the journal Geophysical Research Letters ( GRL).In fact , only about 2 percent of planetary warming from the increase greenhouse issue is used in heating the air , while about90 percent heats the world ’s oceans , according to the Intergovernmental Panel on Climate Change .
In the GRL paper , Magdalena Balmaseda and Erland Källén of the European Centre for Medium Range Weather Forecasts and Kevin Trenberth of the National Center for Atmospheric Research matched sea - heating plant - content measuring with ocean - story , surface temperatures and other types of data . The researchers incorporate that data into climate example simulations to re - create past sea temperature changes .
While someprevious studieshave included ocean temperature datum , until latterly the measure of the deep oceans below 700 meters were relatively thin . By include other types of measuring into their model , this study was able to create a more elaborate moving-picture show of past sea heat changes .
Perception of climate change may be influenced by the frequency that climate-science words appear in the popular literature.
The scientist establish that over the past ten , while surface air temperature have not get up very much , there has been a warming of the deep oceans that is unprecedented over the retiring 50 years . They also set up quickening in the overall warming of the Earth . Consistent withprevious research , they concluded , “ In the last decennary , about 30 percent of the warming has occurred below 700 m , kick in significantly to an acceleration of the warming trend . ” [ Surprising profoundness to Global Warming ’s event ]
The authors suggest that more heat is being transfer to the mystifying ocean layer , due to changes in air current radiation pattern link up with an sea bicycle call the Pacific Decadal Oscillation . However , as Kevin Trenberth explained , this process is only temporary . Sooner or later the warming at the surface will quicken once again , he said , adding , " … it contributes to the overall heating of the recondite sea that has to occur for the system to equilibrise . It speeds that process up . It means less short - full term thawing at the surface , but at the disbursement of a greater , earlier , retentive - term warming , and faster sea - story salary increase . "
This unretentive - terminal figure pause in warming at the Earth ’s airfoil is also consistent with clime model simulations . Research reported in 2011 by Gerald Meehl and his colleagues in Nature Climate Change found that decade - long periods of little or no open - atmosphere thaw are comparatively rough-cut in clime - model simulations . During these so - visit " hiatus decades , " more heating is transferred to the mysterious oceans , coherent with the findings of the Balmaseda team .
When the ocean cycle deepen state again , these modeling tell us that we can look to see a speedy warming of temperatures at the aerofoil . Another study published just this calendar month in the journal Nature Climate Change has conclude that accelerated ocean warming can excuse the slowed surface - air heating in late years . Lead writer Virginie Guemas noted , " If it is only related to natural variability then the rate of warming will increase soon . "
Contrary to claims that world-wide warming has break , the overall warming of the Earth has accelerated over the past decade . While we have receive a respite in warm at the surface , it is a temporary one which will finally be replaced by a rapid thawing of airfoil air temperatures .
