Oceans Heating up Faster Now than in the past 10,000 Years, Says New Study

The world’s oceans are heating up faster now than in the past 10,000 years, says a new study, even though the Earth’s atmospheric temperatures might have been staying on a steady plane recently; with not much global warming being seen over the last couple of years .

In the report, that has just been released in the scientific magazine Science, scientists have stated that the central depths of a portion of the Pacific Ocean have heated up 15 times quicker in the past 60 years than they did over all those thousands of years combined.

Much of the heat that civilization has put in the stratosphere since the 1970s have been from emissions of greenhouse gas. It has been soaked up by the oceans across the Earth, stated that most recent report released from the Intergovernmental Panel on Climate Change; a group created by the United Nations made of researchers that sends out reports every couple of years over the global warming epidemic.

The lead author of the study, Yair Rosenthal, wrote that humanity is pumping warmth into the oceans at a very fast rate. He is a climate scientist who works at Rutgers University. He added that scientists might have underestimated the oceans effectiveness as a heat and energy storehouse.

A co-author of the report, Braddock Linsley, who is a climate scientist of Columbia University, noted that the problems were not so much the scale of the change, but the rate of how fast it is happening. He added that in the last six decades the Pacific Ocean’s temperature from the surface down to around 2,200 feet had risen to around one-third of a degree Fahrenheit. This specific test was done in the Pacific around Indonesia. That area was picked because it was a usual ocean sample. Investigators said that even though the amount of heating may appear small, the rate of warming is what is causing the alarm around the world.

The researchers stated that ocean waters have mostly been cooling over the past 10,000 years, until around 800 years ago, when water temperatures began to slowly rise again. It is only been the last few decades, though, that the heating rate has intensely escalated. The Earth’s atmosphere has stayed about the same temperature for the past 15 years or so, providing fuel for skeptics of man-made global warming. However, this study, along with other newly conducted research, finds that warmth taken in by the planet’s oceans has risen tremendously.

Understandably, no thermometers were around to take measurements of the worlds ocean temperatures over the last thousand years. Researchers used substitution sources to measure water temperature. In this case, they had to look at ancient marine life fossils known as foraminifera, which were little animals in shells. The scientists then were able to recreate the environments in which these creatures lived in over a millennia ago.

When La Nina climate patterns, which are colder than normal Pacific Ocean water temperatures, change, and the Pacific returns to the warmer El Nino climate, worldwide temperatures are likely to rise again, along with the heating rate, stated Kevin Trenberth, a climate scientist at the National Center for Atmospheric Research located in Boulder, CO. He was not part of the study that was released.

However, he also agreed that the oceans are definitely heating up faster now than in the past 10,000 years.
