Since people seem to want to poke at it and pretend science is settled on climate change, lets see a bit about what exactly does science says - first in a series of I dont know how many posts ... The significance of it to me is that apparently, all the rising sea levels stuff that you hear about is based on computer modelling, not actual measurement of the past 20 or 30 years as much. Which is kind of egregious I think. I have not looked into his claims that some of the observation data has been tempered with but the principal point is that satellite data are not prone to such manipulation and they show either much lesser rise in sea level than alarmists claim or no significant increase. For ease of reference, his main points are here: - At most, global average sea level is rising at a rate equivalent to 2-3 inches per century. It is probably not rising at all. - Sea level is measured both by tide gauges and, since 1992, by satellite altimetry. One of the keepers of the satellite record told Professor Mörner that the record had been interfered with to show sea level rising, because the raw data from the satellites showed no increase in global sea level at all. - The raw data from the TOPEX/POSEIDON sea-level satellites, which operated from 1993-2000, shows a slight uptrend in sea level. However, after exclusion of the distorting effects of the Great El Niño Southern Oscillation of 1997/1998, a naturally-occurring event, the sea-level trend is zero. - The GRACE gravitational-anomaly satellites are able to measure ocean mass, from which sea-level change can be directly calculated. The GRACE data show that sea level fell slightly from 2002-2007. - These two distinct satellite systems, using very different measurement methods, produced raw data reaching identical conclusions: sea level is barely rising, if at all. - Sea level is not rising at all in the Maldives, the Laccadives, Tuvalu, India, Bangladesh, French Guyana, Venice, Cuxhaven, Korsør, Saint Paul Island, Qatar, etc. - In the Maldives, a group of Australian environmental scientists uprooted a 50-year-old tree by the shoreline, aiming to conceal the fact that its location indicated that sea level had not been rising. This is a further indication of political tampering with scientific evidence about sea level. - Modelling is not a suitable method of determining global sea-level changes, since a proper evaluation depends upon detailed research in multiple locations with widely-differing characteristics. The true facts are to be found in nature itself. - Since sea level is not rising, the chief ground of concern at the potential effects of anthropogenic “global warming” – that millions of shore-dwellers the world over may be displaced as the oceans expand – is baseless.
