New research shows excessive carbon dioxide in the Oceans pose a serious threat to marine life, food security, and tourism.

“This is, of course, also have an effect on the level of acidity in the oceans, and then (we) than natural increase in the concentration of carbon dioxide emissions with male-male last two hundred years.”

The scientists used a computer model with data from Ice Cores and ocean sediments to simulate the conditions of the sea, returning to the ice age and onward to the end of the 21st century.

When the Earth began to warm 17,000 years ago, at the end of the last ice age, atmospheric CO2 began to increase. 6,000 next year, it grew out of 190 parts per million to 280 parts per million.

Marine systems have time to adjust.

Axel Timmerman is a Professor of Oceanography at the University of Hawaii International Pacific Research Center and a co-author of the study. He said the past 200 years to paint a picture that is a lot different.

“Starting with the pre-Industrial Revolution, anthropogenic emissions increased so much that the ocean suddenly started taking large amounts of carbon.”

The concentration of CO2 in the atmosphere now standing at 392 parts per million. Timmerman said the study, which also includes the observation data for 30 years, found high levels of a dangerous ocean acidification in specific areas.

“Like the Coral triangle, the Western Pacific and Caribbean tropic exceeds the natural rate by factors of up to thirty in some places.”

Timmerman said occurred at accelerated speeds. “The rate of change is about two times more quickly than what happened during the last glacial period about 20 to 15,000 years ago.”

While ocean acidification could have been detected earlier, scientists are just beginning to monitor a few decades ago. Like sea water becomes more acidic, carbonate-mineral sehllfish and coral which many use to form shells and skeletons-reduced.

The concentration of carbon dioxide are estimated to occur in the sea at the end of this century will disturb the fish’s ability to hear, smell, change and avoid predators, research finds.

Australia Research Council Centre of Excellence coral study says it has tested the performance of baby coral fish in seawater containing higher levels of dissolved CO2 over the past few years.

“And now is quite clear that they maintain significant disturbance of the central nervous system, which tends to annoy them a chance to survive,” said Phillip Munday, a professor who reported the findings.

In a paper published in the journal Nature climate change, Munday and his colleagues also detailed what they say is a world-first evidence that high levels of CO2 in seawater disrupt key receptors of the brain of fish.

Scientists say deposit their eggs into the flying bees abdomen, causing infected bees shows a zombie-like behavior by walking around in a circle without a clear sense of direction. The bees leave the nest at night and died shortly thereafter.

Symptoms of Colony Collapse Disorder, the mirror in which all adult honey bees in the colony abruptly disappear.

The disease is a major concern, because the bees pollinate approximately one-third of the United States food supply. Its presence is particularly worrisome in California, the nation’s top producer of fruits and veges, where bees play an important role in the industry $ 2 billion of almond and other plants.

The latest study, published Thursday in science journal PLoS one, points to fly parasites as threats to honey bees. This is another step in the ongoing research to find the cause of the disease.

Researchers haven’t been able to pin down exact cause of colony collapse or find a way to prevent it. As far as research points a combination of factors including pesticide contamination, the lack of interest — and thus nourished-and mites, mildew, viruses and parasites.
