I have a very deep concern regarding the present attitude of the politicians and especially the majority of environmentalists regarding the issue of man-made "global warming".
For a reason to my sceptic approach see more on Global Warming
GLOBAL WARMING AND ANTARCTIC ICE?
It is with great regret that I find media apt to grab any prophesy for catastrophies by "reputed scientist" without hesitation. Melting of the ice on Antarctica has hit the news many times. Likewise the detachment of giant icebergs has been deemed the result of global warming due to manmade increase in carbon dioxide. The movement of the ice cap on Antarctica is governed by precipitation and not by global temperature. The giant iceberg mentioned earlier is a fully natural phenomenon and can not be blamed to any human activities. To state that sea level rises or falls due to global change is completely out of proportion. There are far too many factors affecting this planet from the inside and the outside to warrant the idea that man is capable of influencing these natural processes.
Sea level is governed by the amount of fresh water stored in the ice caps, and precipitation in the polar regions is a function of global sea surface temperature. That is obvious. What is less obvious is the vertical and horisontal crustal movements. We know that many parts of the World experience either a sinking or rising ground surface (in relation to the sea surface). Some of the horisontal ones, e.g. like the Americas moving away from Europe, has been established by satellite measurements. The amount of sediment accumulation into the oceans from land erosion is also a matter to take into consideration. The idea of clathrates (methane ice found abundantely in the oceanic sediments) gasifying and causing a loss in seabed matter and thus causing a lowering of the sea floor is an interetsing idea, but completely irrelevant in the context of sea level rise or plunge. The whole question of sea levels should not be addressed only by land based tide gauges because prior to satellite altimetry there has not been a common reference point of sufficient accuracy.
Coming back to global climate, it has been obvious to me that the stellar influence is the most important factor in this respect. Variations in solar activity is a fact. It has been considered that variations in insolation has not been sufficient to explain measured changes in global climate. However, the effect of solar winds on cosmic radiation has just recently been established and, furthermore, there seems to be a good correlation between cloudiness and variations in the intensity of cosmic radiation. Here we have a mechanism which is a far better explanation to variations in global climate than the attempts by IPCC to blame it all on anthropogenic input of greenhouse gases. On one point I do agree upon, and that is that air pollution, especially around larger cities, should be limited and that should have been the main objective of the Kyoto agreement and not global warming.
The el Niņo Southern Oscillation (ENSO) seem to regulate global climate and also influences the North Atlantic Oscillation (NAO). Not even the IPCC attributes the ENSO or NAO to man-made warning. On the other hand Dr Theodor Landscheidt has clearly demonstrated that ENSO can be forecasted and Timo Niroma has shown how Jupiter influences solar activity. Furthermore Nir Shahiv has shown that galactic cosmic rays (GCR) modulated by the active Sun is a plausible cause for past ice ages. It is obvious that IPCC has completely misunderstood factors influencing global climate and as Landscheidt mentions: "The Third Assessment Report, published by the Intergovernmental Panel on Climate Change (IPCC), continues to underestimate the Sun's role in climate change: "Solar forcing is considerably smaller than the anthropogenic radiative forcings", and its "level of scientific understanding" is "very low", whereas forcing by well-mixed greenhouse gases "continues to enjoy the highest confidence level" as to its scientific understanding."
Marine geological and geophysical research has during the past decades tremendously improved our knowledge of the deep sea and also how the Earth functions. Plate tectonics, movement of the continents and the formation of mid-oceanic ridges are topics of great importance. Black smokers and massive sulphide ores forming on the seabed have completely changed our conception of ore genesis.
