There may be a strange reverse of absence of coral reefs such as ocean-equation

Can be an uphill in the absence of coral reefs. Their disapproval means oceans can absorb up to 5 percent more carbon dioxide in 2100, researchers estimate, slowly establishing this greenhouse gas.

“This is a useful effect if you only care for CO2 concentration in the air,” as LESTER KWIATKOWSKI In the Sorbonne University in Paris, France. But reduced corals also reduces biodiversity, harmful fishing and leave several shores that are more exposed to the rise of the ocean, he said.

What the world is so well alone in many the level of CO2 in the air. So far the land and oceans emit the Middle of the additional CO2 we have released. Any factors that increase or decrease so-called carbon carbon seas can have an important impact on future heating.

It is often believed that corals have removed CO2 from seawater as they grow their calcium carbonate skeleton. Indeed, the process, also known as calculating, a net source of CO2.

“You take the inorganic carbon in the ocean, generally in the form of carbonate and bicarbonate, that the process releases the condition of the sea, which some disappears into the space,” says Kwiatkowski.

It means that if the shape of the reef all over the world slowly or even the changes, the less CO2 will be released to the reefs and the oceans that are not available to the greenhouse models – a factor that is not currently attached to climate models.

Observations suggest that masculinity of coral reef decreases rise in sea water temperature caused by mass coral bleaching and die. The higher level of CO2 Making the ocean more acidicto make it more difficult to build carbonate skeletons and even bringing their omissions.

Kwiatkowski and his team brought approximate estimates of how fences affected by heating and oceans in the oceans and use a computer model to open the oceans in the ocean. They conclude that the oceans can take between 1 and 5 percent more carbon in 2100, and up to 13 percent more than 2300.

This is not considered by other factors that can cause reefs such as excessive repair and the spread of coral diseasessays Kwiatkowski, so it can be a reduction.

On the other hand, the job is considering that Corals are unable to adapt or acclimatise, States Chris Hury At the University of Hawai’i in Manoa, not included in the study.

“If the worst case or even the medium-case situation in this study ends, it means nearly the destruction of coral reefs around the world,” said Jury. “I think that in consideration of realistic level of adaptation and acclimatization of corals and other reefs organisms, the authors can come in different conclusions on a moderate level of climate change.”

If Kwiatkowski team is correct, it means that the amount of issued CO2 to lead to a given level of heating – the so-called Carbon Budget – a little larger than the thought now.

“I think we want our budgets can be as accurate as possible, even if we blow them,” says Kwiatkowski.
