“(CNN) For the past several years, scientists have been trying to get people to wake up to the dangers that lie ahead in rising seas due to climate change. A comprehensive list now names hundreds of US cities, large and small, that may not make it through the next 20, 50 or 80 years due to sea level rise.”
Popular CNN presenter Clarissa Ward, well known for her aching-heartstrings investigations into humanitarian crises, pins her flag to the Climate Change mast in the recent CNN special
“Global Warning.” In itself, taking that position as a journalist is perfectly acceptable, but promoting the kind of money-spinning fraud that underpins the myth of catastrophic sea-level rise is most definitely not.
Clarissa takes the concerned viewer first to Greenland, ostensibly to show where the rising water level is getting its substance from (debatable, but still okay), and then makes her way to South Florida, where her ethics–and her common sense–start to unravel. Alarmingly!
You don’t have to be a rocket scientist to know that water inexorably finds its own level, even if you aren’t familiar with the term used to describe it in physics: Hydrostatic equilibrium. Children learn at an early age by playing with glasses of water that no matter how much you disturb it, water settles back to a uniformly smooth surface on average. The oceans bulge and subside with the tidal pull, but a high tide doesn’t ever stay a high tide for long.
Overall, the sea is level at sea level, if you get my drift.
Clarissa interviews Michael Mann to provide “expert” testimony supporting her programme’s contention that Climate Change (aka AGW) causes the sea level to rise dramatically and permanently — AT SELECTED SPOTS ON THE GLOBE!
Look at it this way — if the sea level rises by a metre at Miami Beach, and at certain South Sea islands, it will present one of two scenarios. Either sea level will subside again at those places within a short period of time back to the normal sea level; or, if it is indeed a sign of sea level rise, all the rest of the oceans will show a similar increase in surface height. In the latter case, sea level rise on the beaches of South Florida will be matched by the rise of the water mark on the concrete sides of the Suez Canal. Or at the docks in Durban. Or the beaches of Ethiopia.
Here’s the formula: If the relative differential of land and ocean levels in a particular spot decreases but not in others, then it is obvious that the land there has subsided.
If you use the data available from submerging land masses to propagate a political theory that requires sea levels to rise catastrophically before our eyes, then you are either very stupid (and neither Michael Mann nor Clarissa Ward is stupid, as far as I can tell), or you are devious and conniving.
Do the maths.
“In other words, the slow rise of 1- to 2 mm per year in global sea level is an artifact of our current interglacial period. Local sea level rise or fall depends on local geology, the amount of groundwater pumping in coastal areas, and the cyclic weather patterns. It has nothing to do with carbon dioxide emissions.
