Caroline Lucas – 2015 Parliamentary Question to the Department for Environment, Food and Rural Affairs

The below Parliamentary question was asked by Caroline Lucas on 2015-12-01.

To ask the Secretary of State for Environment, Food and Rural Affairs, what her policy is on the level of atmospheric carbon concentration required to prevent harmful ocean acidification; what assessment she has made of the effect of ocean acidification under atmospheric carbon concentration scenarios used by the Intergovernmental Panel on Climate Change on (a) marine species and (b) coastal populations; and if she will make a statement.

George Eustice

Defra and DECC have together supported the UK Ocean Acidification Programme to better understand the impacts of climate change on our seas.

Although we are still awaiting the final summary report, outputs from the programme point to a complex range of effects on marine species and ecosystems resulting from the interplay between acidification and temperature increase. The economic effects on coastal populations are uncertain at this point though preliminary work indicates they are likely to be increasingly negative as the century progresses.

However, by reducing emissions in line with the stringent emissions scenario produced by the Intergovernmental Panel on Climate Change (Representative Concentration Pathway 2.6) which is consistent with keeping mean global temperature increase below 2°C, we would significantly increase the options for protection, adaptation and repair of the ocean.

This is why the UK Government is seeking ambitious global action on climate change this month in Paris to protect our oceans in the future.
