I am a practicing professional petroleum geologist for the last 15 years; there is one law that my lecturers and the textbooks have taught me that remains a fundamental rule to viewing all things past and present.
"the present is the key to the past"
Addressing Global warming; we apply that simple basic rule, look at the processes that are taking place today (present) in our lives, document the changes, the various environmental and other factors at play, and take that into the past. By taking into the past we look at rock records. The rocks are a perfect record of the "past", by carefully analyzing and reading the records in the rocks. We can than fast-track back into the future and predict and foretell the future. Now that is not hard to do, everybody can do that if they try.
PNG is so far away from the N-S Polar caps to see and measure with our eyes that; "the ice are melting at a faster rate". But we do have our own evidence that; "something is really happening...in way of rising sea-levels". You just have to look at our coastal villages and islands and atolls, case in point is the present day sufferings of the Carteret islands and the inhabitants. For historical geological records we dont have to look further than the Terraced slopes of Finshafhen/Finisterre.
In geological terms:
Carteret is the present; it is the key to the past; the past is the Terraced slopes of Finshafhen/Finisterre. The processes may not be exactly the same but the outcome in the rock records does tells us today that major catastropic events do occur within geological time. Now mind you; geological processes dont care about the short memories and written records of humans, about our day to day activities and what our children will have when we are gone. Geological processes have their own rules and timelines. The best man can do is to fit into the entire scheme of things that are far larger and more powerful that we cannot stop/control. We simply have to apply the rules of nature into our scheme of things than to build rules for nature to abide...which is impossible.
Now to the scientists and organisations that are saying that; "Global warming is a Scam". First and foremost, most of them are sitting in chairs so far away from what is really and truly happening in the world. They sit behind computers and model all sorts of events with their theoritical rules and laws that are not consistent with hard evidence in the "rock records". The next factor is they simply forget that dealing with these global-geologically-framed events, they have to throw their timeline out the window and use geological timeframes. They just need to do these basic things to put some juice/evidence into their theory/models and than they will come up with something different. But than again those kinds of research and results will not be paid for by companies/corporations/governments/organisations who foot the bills and put food on the table for them. They want the world to believe that; "global warming is a scam".
I have personally walked the shoreline villages along Popodetta to Lae, north coast of Madang, and along the flooded banks and inlets of Purari. Everywhere, people, our people are looking to shift inland, their fertile lowlands along the coasts for Yam, Taro, Banana and coconuts and beetle-nut are dying due to sea-water flooding. I have silently watched the rising effects of sealine along Madang town, and I am sorry to say but; Madang will be under water within the next 5-10 years.
Most parts of Madang town will be waterlogged, or flooded. Madang airport will be closed. Divine Word University is a meter or less to present SL, the grounds will be water logged, the campus will be closed.
PNG...it is happening, we don't even have to think it is a scam, in 20-50 years, still in our lifetime; our our shores, towns, villages will be forever written into the permanent records of "THE ROCKS".
