Sea level rising

In this video, Dr. Nathan B. English talks through the impacts of rising sea levels.

One of the major effects caused by increasing atmospheric temperatures is rising ocean levels.

In this step, Dr. Nathan B. English revisits the scenarios he introduced in the Global Warming step to explore the effect of increased anthropogenic greenhouse gas emissions on the oceans.

Now it’s your turn

Dr. English refers to the oceans as a ‘slow learner’, meaning that the impact of changes to greenhouse gas emissions may take longer to realise. What impact do you think this will have on the way policymakers address the problem of rising sea levels? Share your thoughts in the comments.
