The Atlantic ocean could be contributing to the 'pause' in global warming by drawing down heat by nearly a mile, according to a new study.
The research from the University of Washington shows that heat from the surface is plunging deep in the north and south Atlantic, affecting the balance between incoming heat and heat radiated back into the atmosphere. The study is published in Science.
Recent measurements of ocean temperature made by thousands of buoys and observations of Earth's radiative energy by satellite instruments have shown that the Earth is warming up. In fact, Earth's heating rate increased between the 1985-1999 and 2000-2012 periods.
But this increased heating has not directly corresponded with surface warming - and apparently, the answer could be found deep in the Atlantic.
The temperature at the Earth's surface depends upon where the heat is deposited in the oceans. If the upper levels warm, so too will the atmosphere above it. However, if ocean circulations cause more heat to be drawn down to deeper depths, then surface temperatures will cool.
Ka-Kit Tung, a University of Washington professor of applied mathematics and co-author Xianyao Chen of the Ocean University of China, observed deep-sea temperatures from Argo floats that sample the water down to 6,500ft (2,000m).
The authors say that fluctations in surface temperature are part of a cycle involving ocean circulation responses to changes in how dense the upper Atlantic Ocean layers are - ie, how saline they are.
The cycle starts when saltier, denser water at the surface northern part of the Atlantic, near Iceland, causes the water to sink, taking heat down with it. This changes the speed of the current in the Atlantic Ocean that circulates heat throughout the planet.
Recent observations at the surface in the North Atlantic show record-high saltiness, Tung said, while at the same time, deeper water in the North Atlantic shows increasing amounts of heat.
The cycle switches naturally between warm and cool because of tropical water being carried to the North Atlantic, warming the surface and deep water and causing ice to melt. In turn, this makes the surface water there less dense and after a few decades will set off the cooling phase.
After 30 years of warming, the researchers say we are now in the 'cool' phase.
The pause in global warming has been attributed to many environmental factors, with another recent study from ETH Zurich citing climate fluctuations like El Nino and solar irradiance. The team also said that global warming would continue once these natural fluctuations settle down
The warm periods between ice ages lasted 10-20,000 years. We’ve had a 12K warm period, so we could easily be seeing the start of the next ice age.
All you need is for last year’s snow not to melt before the next one comes.
They now have nothing to worry about. All the heat goes deep into the ocean.
Problem solve. Debate settled.
Now on to how leprechauns are causing the decrease in the unicorn population. Send your money today and beg the government for restrictions on your freedom to SAVE THE UNICORNS!
Everytime you drive an SUV a leprechaun kills another unicorn. 1250 grant dependent scientists agree.
Only the fringe “Scientists” disagree with the government findings and the UN study on unicorn depopulation. Also call “unicorn disruptification”.
Some deniers claim that unicorns do not even exist. The EPA plans to tax them heavily and send a special “task force” similar to the Spanish Inquisition to deal with these heretics.
These anti-science “scientists” exist for (a) increasing their haul of grant money from taxpayers and (b) pushing their malignant, ideological perspectives through their “science”. They all should be beaten with their worthless, obscure dissertations. Then, they should be forced to wander the country dressed in sack cloth begging for forgiveness for their crimes against logic and decency. Frauds all.
For example, the snow of Antarctica and snowmelt is what keeps our planet cooled. When the salt separates from the glaciers it slides down to the floor of the ocean like a river to both the Atlantic and the Pacific oceans.
So, all these hand-wringers who keep us alarmed whenever the Antarctic glaciers begin to calve don't know what they are talking about. It is precisely the glacial melt that benefits Earth and is primarily instrumental for keeping our Earth from turning into Mars.
In fact, the interplaying systems of Earth are so huge and dynamic that it is puzzling to think how man could ever think that his interference would amount to a hill of beans
The episode was called - Earth from Space.
Mother Gaia witnessing Biden skinny dipping should be worth a volcanic barfing or two.
That’s miraculous.

The media desperately wants this story buried.
Global warming sleeps with the fishes

This cycle switches naturally??? What?? How can that possibly be?? But, all the smart people assure us that all this climate change is manmade. < sarcasm off >
To be a “climate change scientist” must cause one to live under a great cloud of anxiety.
