In the depths of the Pacific Ocean, cold and cold water, the temperatures continue to decline. XVI. Everything that was cool was started in the century.
Even though the surface temperature of the ocean surface rises, it seems that the message has not been reached at the Pacific basin. Over the world, there have been postponed some centuries in terms of temperature models, according to new research.
"It changes throughout all the changing climates," said Earth and Planetary scientist Peter Huybers at Harvard John A. Paulson School of Engineering and Applied Sciences.
"Some of the regional warming and cooling systems, such as the Little Ice Age and the Middle Ages, are known to develop a model that responds to the changes in climate change in the ocean."
The Little Ice Age, as it is known, is a period of cooling between 1550 and 1850 between the years 1550 and 1850, following the warm Middle Ages.
However, despite the name, there was no ice to ice, because the regions occurred, but rather in general.
But the regions that had a great influence were abundant and abundant, and, of course, the oceans.
The ocean circulation takes a very long time. When water is sinking, the atmosphere (and temperature) is insulated between 8 and 14 miles.
This means that the depths of still water in the crust of the ice creams are cooling, after warmer medieval waters than warmer waters.
"These waters are so old and have not been so long ago, they still remember," some of the coldest winters of history in Europe were happening a few years ago, "said Jake Gebbie, the fiscal physicist of Woods, Hole Oceanographic Institution.
"If the rest of the ocean melts due to the improvement of the last millennium, most of the isolation of modern warming is still cools."
The Group used data and computer modeling to discover the deep circulation in the Pacific since 1870.
In the 1990s, the World Pacific Circulation Experiment took a number of readings of the Pacific temperature of 2 kilometers (1.24 km).
Between 1872 and 1876, scientists aboard HMS Challenger repeatedly immersed a thermometer to the world's oceans, 5000 temperatures and 2 kilometers depth.
"We analyzed the historical data we present, stretching the hemp ropes used to reduce the thermometers pressure effects and thermometers," said Huybers.
Once corrected and corrected the data, WOCE's most recent data was compared.
As planned, Gebbie and Huybers found a warming trend closer to the surface, but between 1.8 and 2.6 kilometers (1.1 to 1.6 kilometers), the ocean cooled.
There is not a large amount – only between 0.02 and 0.08 degrees-but compared to the trend of global warming, the result is intriguing.
And it shows how the planet's warming has an impact, so that previous climate change can affect the current climate change rate.
That is why Land XX. It is based on the balance of the prevailing estimation before the industrial revolution in the 19th century.
But this discovery indicates that Earth's heats up 30 percent less than these estimates.
"Part of the heat needed to convert the ocean into the ocean, due to the greenhouse effect of greenhouse gases, already had a deep depth already," said Huybers.
"These findings increase the understanding of the causes of the Middle Ages and the Ice Age to know better the tendency of modern warming".
