In PNG we dont have all the fancy gadgets, computer power and money to research for proof. All we get is information that are both contradictory.
But we go by the facts we see today, and if you listen to older generation legends and stories, you will know, the Sea Level was far below or away than it is today.
Big cities like New York, London, Tokyo, Sydney, Paris...people spend alot of time living and working in tall sky scrapers they don't even give a care the pacific islanders who sleep on the ground are drowning.
Sea-level rise is of no concern to them; so they will continue to call it a scam.
