One this that is certain is that we should intervene fast to reduce climate change and its negative impact on ecosystems. Now, new research revealed that to combat global warming better, we should focus on ocean-based solutions. According to the scientists, to reduce carbon dioxide emissions, tackle ocean warming, and diminish the acidifications of seawater are among the best solutions to address climate change.
Published in Frontiers in the Marine Science journal, the new study points out the trade-offs and governance issues linked to all solutions that might tackle climate change. The researchers also highlighted that the most significant benefit would come from mixing global and local solutions via policy cooperation, according to the research, cited by EurekAlert.
“The ocean already removes around 25% of anthropogenic CO2 emissions and could remove and store much more. However little guidance is currently available on which ocean-based interventions will work best to reduce the scale and impacts of climate change,” explained Dr. Jean-Pierre Gattuso from the CNRS, in France, and the study’s leading author.
Climate Change Fight Should Center On Ocean-Based Solutions
Dr. Gattuso and his co-workers, an international team of scientists, came up with 13 solutions in tackling climate change, categorized in four sections:
- Reducing atmospheric CO2 concentrations;
- Increasing the solar radiation reflection;
- Protecting marine ecosystems
- Manipulating adaptation to climate change impacts, biologically and ecologically;
The scientists examined each measure in part for reducing ocean warming, ocean acidification and sea-level rise. Ocean-based solutions seemed like the best ones against climate change.
“Not only do offshore wind farms, wave energy, and other ocean renewables have a very large potential to reduce carbon emissions, but they are also cost-effective and ready to be implemented at a large-scale,” says Dr. Alexandre Magnan, the study’s co-author.
“The potential for ocean-based solutions to address climate change and its impacts is very high and depends on societies’ ability, from local to international levels, to decide about the right combination of measures,” Magnan concluded.
