Letter to Christchurch Press from David Beach, 4 Aug 2015. Click to enlarge.
David Beach sent a letter to the Christchurch Press published 4 August, 2015, which contains grievous errors. Whatever he intends by the use of the term ‘exponential’, we can only take it in its usual sense of increasing at a more and more rapid rate, or a rate expressed by a mathematical exponent. His salient point is this:
First, the 1m figure is absolutely the best case for sea level rise. The worst case (expressed by an expert team led by Dr Hansen) is 5m. Second, it does not stop at whatever figure turns out to be true, as it increases exponentially.
