Deep in the ocean, the true scale of global warming is hidden

  • Scientists looked at a layer of the oceans between 300 and 1,000ft
  • They found it has been accumulating more heat than first thought
  • Study looked at direct ocean temperature data for more accurate results
  • Previous attempts to explain the temperature trends have relied heavily on climate model results which are less able to deal with short-term data

By ELLIE ZOLFAGHARIFARD FOR DAILYMAIL.COM 9 July 2015 Powerful winds in the Pacific and Indian oceans are hiding the effects of global warming.
This is according to a new report that claims the so-called ‘pause’ in climate change never took place – scientists just haven’t been digging deep enough.
The pause refers to the fact that the temperature of Earth’s surface has increased by just 0.06°C in the past 15 years.
A new report claims the so-called ‘pause’ in climate change never took place – scientists just haven’t been digging deep enough. Temperature data from the global ocean (2003-2012) at four depths shows the warmest water at depths of about 330-660 feet
It has been used by some groups as evidence that climate change is not happening.

HOW OCEANS CAN BURY HEAT

Scientists claim one of the causes of the‘plateau’ in sea-surface temperature is a change in the exchange of ocean water.
They believe this exchange is occurring between warm, surface waters and cold, deep waters – as if the warming is ‘hiding’ underwater.
Easterly trade winds of the Pacific Ocean have increased significantly over the past two decades and as a result are blowing higher volumes of warm surface sea water to deeper depths.
Stronger trade winds blowing from South America to Australia have had the net effect of cooling surface temperatures by a global average of between 0.1°C and 0.2°C,
This would be enough to account for the apparent hiatus in global average temperatures over the past 15 years.
The warm water won’t hide below the surface forever: scientists believe that it may re-emerge later or affect other climate indicators, such as sea level or ocean circulation.
But the Nasa study claims the planet’s extra heat has spent the last 10 years sinking into the depths of equatorial waters.
Scientists have found a specific layer of the Indian and Pacific oceans between 300 and 1,000ft (100 and 300 metres) below the surface has been accumulating more heat than previously recognised.
The team, which included Veronica Nieves, Josh Willis and Bill Patzert of Nasa’s Jet Propulsion Laboratory, also found the movement of warm water affected surface temperatures.
During the 20th century, as greenhouse gas concentrations increased and trapped more heat energy on Earth, global surface temperatures also increased.
However, in the 21st century, this pattern seemed to change temporarily.
‘Greenhouse gases continued to trap extra heat, but for about 10 years starting in the early 2000s, global average surface temperature stopped climbing, and even cooled a bit,’ said Willis.
In the study, researchers looked at direct ocean temperature measurements, including observations from a global network of about 3,500 ocean temperature probes known as the Argo array.
These measurements show temperatures below the surface have been increasing.
The Pacific Ocean is main source of the subsurface warm water found in the study, though some of that water now has been pushed to the Indian Ocean.
