Marine reserves may mitigate climate change impact
Highly protected marine reserves can help mitigate sea-level rise, ocean acidification and other major impacts of climate change, scientists say.The study showed that reserves can help marine ecosystems and people adapt to key impacts of climate change such as ocean acidification, sea-level rise, increased intensity of storms, shifts in species distribution, and decreased productivity and oxygen a
London: Highly protected marine reserves can help mitigate sea-level rise, ocean acidification and other major impacts of climate change, scientists say.The study showed that reserves can help marine ecosystems and people adapt to key impacts of climate change such as ocean acidification, sea-level rise, increased intensity of storms, shifts in species distribution, and decreased productivity and oxygen availability.
The reserves can also promote uptake and long-term storage of carbon from greenhouse gas emissions, especially in coastal wetlands, which helps reduce the rate of climate change.
However, these benefits can be greater only in large, long-established, well-managed reserves that have full protection from activities such as fishing, oil and mineral extraction.
Relative isolation from damaging human activities may add to further conservation benefits, the researchers said.
"Well-managed marine reserves can offer the ocean ecosystem and people critical resilience benefits to rapid climate change," said lead author Callum Roberts, Professor at the University of York.
Further, the study, published in the Proceedings of the National Academy of Sciences, showed that protecting more of the ocean will also improve the outlook for environmental recovery after greenhouse gas emissions have been brought under control.
