Climate Changes Cause Dire Oxygen Loss in Oceans
A new study reveals a dire, slow death, of the world's oceans at a much more rapid pace that siphons out precious oxygen. Without it, sea life dies. Without that, so do we to some degree. Scientists have long known that in the deglaciation period there were increasing temperatures, surging levels of carbon dioxide in the atmosphere and rising sea levels. This is a period that did occur 10,000 years ago. A period when glaciers of ice melted. Life then, became extinct in some areas. Core samples from the ocean floor tell a story of plummeting losses of oxygen levels in the ocean during this time.
Today, the same dire consequences are happening after core samples taken from the the Pacific and Indian oceans tell what the future will be by 2100. The cores provide the health state of the oceans. Like 10,000 years ago, scientists are sounding the alarm of the same plummeting loss of oxygen levels in the oceans. As the oceans become oxygen depleted, more and more species of sea life will vanish and die. This will impact food supplies to billions of people who rely on it. When it is gone, they will turn to other food sources and put increasing pressure on those ecosystems until they deplete and so on. The report showed that no matter where the core samples were taken, the result showed the same dire data- dramatic loss of oxygen in the ocean. It is all tied to rising surface temperatures, high carbon dioxide levels in the atmosphere from emissions from all sources, and rising sea levels. Oxygen loss has occurred in water as deep as 3000 meters and as shallow as 100 meters.
Every so often, mankind experiences an unexplained or rare phenomenon. In the past, there have been sudden loss of sea life that have experts making guesses as to what killed them. Some state oxygen depletion or other that is related to this problem. 2014 was the hottest year for the world ever recorded. This is the fourth year of drought for California and other weather extremes occur elsewhere. Global sea level rose 6.7 inches in the 20th century. The rate in the last decade (since 2005), is nearly double that of the last century! Greenland lost 36 to 60 cubic miles of ice per year between 2002 and 2006, while Antarctica lost about 152 36 cubic miles of ice between 2002 and 2005. The oceans, as the study shows, are becoming more acidic due to the two billion tons of carbon dioxide being absorbed. Carbon dioxide has dramatically increased with China becoming a new manufacturing giant. As the ocean becomes more acidic, sea life dies.
The problem is worldwide, yet unless all major industrial nations really decide to halt the pollution, mankind is basically committing suicide, much like a person who smokes cigarettes. They know they are paying for their own death. They know what the future will be if they continue.
