Not exact matches

Five cultures each were kept under control conditions (15 °C) and at elevated water temperature (26 °C) in combination with three different concentrations of carbon dioxide (CO2): a control value with today's conditions, the conditions of the Intergovernmental Panel on Climate Change's «worst case scenario» and the highest possible degree of acidification.

Now, scientists have suggested that corals have some active control over their skeletal growth — and that it may protect them from the worst ravages of ocean acidification.

For the study, five cultures were kept under a constant temperature and three different concentrations of carbon dioxide (CO2): a control value with today's conditions, the conditions that could be reached until the end of this century according to the most critical calculations of the Intergovernmental Panel on Climate Change (IPCC), and the highest possible degree of acidification.

Geoengineering methods that don't remove carbon dioxide from the atmosphere don't undo the other effects of high atmosphere carbon - dioxide concentrations such as ocean acidification, and our ability to adequately control geoengineering with sunlight - reflecting particles is not certain.

You can have a differential impact on biology and chemistry, so if you really want to assess what will be the status of calcifying organisms in 2100 there is one part, the chemistry, for which the organisms have no control but for the biology they can perhaps adapt and there might be a way for the organisms to mitigate the negative impacts of ocean acidification.

Since you state that a decrease in net calcification could result from a decrease in gross calcification, an increase in dissolution rates, or both, you distinguish between these responses and get to the conclusion that the impact of ocean acidification on a creature's net calcification may be largely controlled by the status of its protective organic cover and that the net slowdown in skeletal growth under increased CO2 occurs not because these organisms are unable to calcify, but rather because their unprotected skeleton is dissolving faster.

Key elements include curbing human carbon dioxide emissions to the atmosphere, improved control of local pollution sources, reducing coastal habitat destruction, and better preparing coastal human communities to withstand the amount of ocean acidification and climate change that is unavoidable.

The Environmental Protection Agency is investigating whether it can use the Clean Water Act to control greenhouse gas emissions because of ocean acidification.

Elsewhere researchers concluded that in addition to atmospheric pH, the complex interactions controlling pH especially in coastal zones, make detection of any trends towards acidification «not trivial and the attribution of these changes to anthropogenic CO2 emissions is even more problematic.»

Furthermore, by working in controlled areas of a natural reef community, Caldeira, Albright, and their team were able to demonstrate how acidification affects coral reefs on the ecosystem scale, not just in terms of individual organisms or species, as other studies have done.

The effects classified as «acidification» encompass an array of issues concerning relative concentrations of various ionic compounds that are dynamically controlled by marine life using regulatory pumps etc..

The intense variability and multiple, complex controls on pH implies that the concept of ocean acidification due to anthropogenic CO2 emissions can not be transposed to coastal ecosystems directly.

Scientists pondering geoengineering ideas argue that such cooling schemes could be hard to control and wouldn't address the acidification of the oceans caused by CO2.
