Mr. Mark Adamson:

We based the mid-range future scenarios, the high-end future scenarios and the allowances for changes in flows and sea level rise on the science available at the time. When the fourth assessment report came out from the Intergovernmental Panel on Climate Change, IPCC, in 2014, it supported the allowances we had made.

I refer to the recent report on global warming of 1.5o Celsius, which the Deputy mentioned. The mid-range future scenario falls in the middle of the range of sea level rise projected in that report, with the 1 m sea level rise actually being above the projected range with global warming of 1.5o Celsius and indeed global warming of a 2o Celsius global warming where there might be a rise of an additional 10 cm or 20 cm. I believe the scenarios we have used to assess our vulnerabilities and that we will use going forward to ensure we are designing our flood relief schemes to cater for potential changes in future decades are reasonably robust.
