It appears that Rob Colemore (The Weekend Sun, July 19) and Peter Otway (The Weekend Sun August 2) disagree sharply. Who is right? Are we informing our future generation correctly as my son is very much in the minority at school in not believing climate change propaganda.

He has good reason to not believe. For decades now we've heard the sea is rising due to climate change and some predictions have placed it up to three metres higher.

But as three generations of my family have lived off the sea and almost every day observed tide heights/weather conditions, highs and lows, on both coasts for over seventy years, the verdict is in.

Absolutely no change! I think the problem is we've got better cameras and programs to film events in way out places. Most people would think hell had broken loose if we had been filmed crossing the Manukau Bar in the 1970's in up to 130km/h wind and waves breaking in 12 metres of water. I could do a documentary and point out these are normal global conditions.
