Their preliminary results suggest important insights into the impacts of
ocean acidification on marine life and their consequences both for society and economy.
They were caused by changes to the ocean's chemistry brought about by absorption of two primary greenhouse gases, carbon dioxide and methane, through a process of
acidification of ocean water.
Working out just how they do this will be important in understanding the likely impacts of ocean
acidification on coral communities elsewhere, he says.
The results of this study demonstrate the importance of investigating the effects of ocean
acidification in natural communities.
Changes in deep - water ventilation could potentially cause
acidification from organic matter breakdown.
Such efforts must remove atmospheric CO2, if they are to address direct CO2 effects such as ocean
acidification as well as climate change.
Whether they could survive both a sustained rise in temperatures and the
increasing acidification of the oceans that goes with higher carbon dioxide levels is another matter.
But there are considerable differences between such systems and the situation arising from global - scale ocean
acidification caused by rising atmospheric CO2.
Heavy metals and other pollutants could be monitored in wastewater and oceans could be monitored for
acidification due to climate change.
We'll examine the results of the first full - scale study of how
acidification affects marine ecosystems.
While anthropogenic CO2 emissions are driving
acidification at global scales, processes occurring at local scales can also affect ocean chemistry.
As for climate policy, one needs to consider the ecological and agricultural impacts of warming and ocean
acidification if one expects to be taken seriously.
But I did not know (and it is very new science) that
acidification also reduces a form of carbonate necessary for tiny ocean life to capture needed iron.
We conclude that near future ocean
acidification levels is not an immediate threat to the early life history stages of Great Barrier Reef corals in the foreseeable future.
If ocean
acidification continues at the current rate, many species at the bottom of the food chain, as well as corals, could face extinction.
Five research priorities are also identified to incorporate ocean
acidification into conservation planning and management.
Now, this will make many readers mad, but does a warming world with ocean currents,
acidification changes have anything to do with this?
The last major
acidification event 250 million years ago has apparently led to a massive extinction of species in the world's oceans.
The faster people understand how ocean
acidification poses a threat to that way of life, the better our chance of protecting it.
But we also know that reducing the rate of carbon dioxide emissions will
slow acidification.
However, it is carbon dioxide in particular that has been the biggest contributor to global warming and ocean
acidification so far.
The projected rates of CO2 absorption in the future [88] suggest that ocean
acidification represents a relatively slow driver of future ecological change.
And just as for sea butterflies, the carbonate shortage that comes with ocean
acidification means trouble for coral reefs.
There is now urgency for new research to respond to a much tougher question: To what extent will ocean
acidification alter marine ecosystems and biodiversity?
In turn, toxic materials are left roaming around,
creating acidification in the blood, and allowing further systemic infections to potentially take hold.
Where atmospheric CO2 works on a rather abstract, global scale, ocean
acidification works on the local one as well, devastating or sometimes completely destroying local ecosystems.
The evidence for evolutionary adaptation to ocean
acidification comes mainly from two approaches.
That's decidedly good news, but it comes with a catch: Rising levels of CO2 in the ocean
promote acidification, which breaks down the calcium carbonate shells of some marine organisms.
Ultimately, though, whether corals will survive sea level rise or ocean
acidification depends on how much the oceans change and how quickly.
