Oceans absorb massive quantities of carbon dioxide

The oceans play a very important role in controlling Earth’s climate. New research has shown that the planet’s five oceans absorb much more carbon dioxide, one of the gases responsible for the greenhouse effect, than previously thought.

The oceans have absorbed over 90% of the extra heat caused by greenhouse gases from human activity over the last fifty years, and they also help cool the planet by absorbing carbon dioxide, says an article on the website of the European Space Agency (ESA).

Previous research had shown that the world’s five oceans absorb about a quarter of anthropogenic carbon dioxide. In some ocean regions, that quantity of carbon dioxide is stored for centuries, thereby reducing the impact of global warming.

In the course of the new research, scientists examined upward and downward carbon dioxide flows
at the surface of the seas –
a process largely regulated
by turbulence. The research has shown that that Earth’s surface waters absorb three gigatonnes of carbon a year,

said David Woolf, associate professor at Heriot-Watt University in Scotland, and lead author of the study.

Researchers created a database, the Surface Ocean Carbon Dioxide Atlas in order to form a better understanding of the carbon dioxide absorption capacity of the ocean. The database is the result of ongoing international cooperation to collect carbon dioxide data measured at the surface of the ocean at various points around the world.

Corals back from the dead discovered in the Mediterranean Sea

For the first time ever, living polyps were discovered in Mediterranean coral colonies that were previously thought to be completely dead by researchers who published their finding in the periodical Science Advances.

Temperatures in Israel increase by 0.25 degrees Celsius per decade

According to a study published in the International Journal of Climatology, Israel’s average temperature has been rising continuously since the proclamation of the Middle Eastern state in 1948, but over the last thirty years the rate of warming has also increased.

Temperatures increase much faster than global average in the Mediterranean region

Temperatures are rising much faster than the global average in the region of the Mediterranean Sea, and this represents a threat to the food and water resources of the region, researchers have warned in a new study.

Fates, faces, contrasts
