The devastating effects of climate change certainly aren’t restricted to sea level rise, yet we are seeing one of its impacts on the power of waves increasing right across the southern hemisphere.

We were joined by Senior Risk Scientist at Risk Frontiers Thomas Mortlock to discuss coastal erosion, and what this means for us.
