There was an article by Jonathan Leake (Sunday Times), describing the existance of oceans' death zones. As per the artcle, researchers in their 50 years of study in Atlantic and Pacific oceans, found that the warming of sea water through climate change is reduing it's ability to carry dissolved oxygen. This results in the death of marine life which depends on the oxygen in water for survival. Human population, which depends on marine life also suffers due to this. It is reported that at 0 degree centigrade, 1 kg of water can hold about 10 ml of dissolved oxygen but at 25 degrees, this falls to just 4 ml. Such layers of dead zones can stretch up to a few thousands of miles and a few hundreds of feet deep in oceans.
It is also reported that about 250 million years ago, average oxygen levels in oceans dropped to almost to zero, resulting in the drastic climate change and extinction of 95% of the world's species.
Now, what might have been the cause for the ocean water warming up, which resulted in the 0-level of dissolved oxygen?
Thank god, now we have NASA to warn us about the global warming!
