One-sixth of all marine life could perish by the end of the century due to climate change

Warming may reduce marine life by 17 percent. The world’s oceans could lose one-sixth of their fish and other marine life by the end of the century if climate change continues at the present rate – claim marine biologists.

Every single degree Celsius that the world’s oceans warm will reduce the quantity of sea animals by 5 percent, says a computer-based comparative study performed by an international team of marine biologists.

The analysis doesn’t even take the effects of fishing into account – the PhysOrg popular science portal reported.

"We will see a large decrease in the biomass of the oceans unless the world slows climate change,”

said William Cheung, a marine biologist at the University of British Columbia and co-author of the study.

Although water temperature is the strongest factor, climate change may also result in acidification of the oceans and reductions in oxygen content, which will also damage marine life.

"The good news here is that the main building blocks of marine life, plankton and bacteria may decline less heavily, the bad news is that those marine animals that we use directly, and care about most deeply, are predicted
to suffer the most as climate change
is working its way up the food chain,”

said Boris Worm, a researcher at Dalhousie University in Canada.

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.

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.

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

The news about climate refugees are alternating sequences of frightening numbers and apocalyptic landscapes that obscure the real face of the problem: the disfigured human fates.

Climate change causing great damage to UK wildlife

More than a quarter of all mammals are threatened with extinction.

Several hundred temperature records broken in 2019

Between 1 May and 30 August, higher than ever temperatures have been measured in 29 countries, on almost 400 occasions in the Northern Hemisphere.

The perishing glaciers of the Alps – shown from a special perspective

The French falconer Jacques-Olivier Travers has surveyed the glaciers of the Alps using a camera attached to a white-tailed eagle.

The Polarstern sets off on a unique expedition frozen to an ice floe

The ice floe that the German research boat will be attached to as it drifts around the Arctic for almost a year on the most important Arctic expedition ever has been selected.

September 2019 the warmest so far

Data from European climate researchers indicates that this year’s was the warmest September since the Copernicus Climate Change Service began keeping regular records of meteorological data in 1981.
