Renewable ocean energy and the international law and policy seascape: global currents, regional surges.

There is an urgent need to increase global renewable energy production as a method of lowering greenhouse gas (GHG) emissions in order to avoid the more devastating effects of climate change and ocean acidification. The latest figures from the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC), suggest that the international community must reduce anthropogenic GHG emissions by 40 to 70 percent from 2010 levels by 2050, and should aim for near zero emissions by 2100. This would likely keep temperature change below 2°C relative to pre-industrial levels, and would therefore reduce the risk of predicted effects of climate change, such as inland flooding, extreme weather events, food security, and the loss of marine and coastal ecosystems and biodiversity.
