A few must watches for young thoughtful readers.

I see more misinformation is being promulgated by Alistair Brickell in Hauraki Herald "Conversations". For example, he states "there is no evidence anywhere in the world of any increase in the actual rate of sea level rise." That is totally incorrect because over the last century the average global increase was about 1.3mm per year. It is now 3.4mm per year and there is an enormous body of evidence that the rate will increase. Yes, so far the rise has been essentially linear but there are strong hints that we may soon record an exponential curve. One hopes that its exponent will be small. Here is the actual past record.

However, sea level rise is only part of the problem for those living close to the sea. Storms and their tidal surges are already more prevalent and they are projected to become worse. Indeed, cyclones are increasingly impacting New Zealand.
Unfortunately much of the information has been produced by those in the northern hemisphere where climate changes are ahead of those here in the south due to changes in the Arctic. We should learn from them because we are only decades behind and we should all be watching Antarctic events with immense interest..

Here is another excellent video that is highly educational. Young persons currently thinking about buying a future property have only themselves to blame if they do not educate themselves.

Brickell is partly correct in regards to future costs. Over coming decades there will be a retreat from sections of our coasts especially as properties become increasing flood risks. Thus there will be increased insurance costs. Indeed, its happening already.
We are also paying for flood protection, especially for the plains. I leave it to readers to guess if costs might increase over coming decades.
 In regards to protecting currently endangered properties especially along the Thames coast etc, it is a cost benefit exercise. Will providing storm surge protections (e.g. sea walls) provide more financial benefit to our overal communities than for example losing homes that might have decades of ensurable future use? I suspect a sea wall that will protect current homes at least for their estimated lifetimes is worthwhile.
I worry for my grand children and especially their offspring.
