THE ANTARCTIC IS THE KEY TO SEA-LEVEL RISE, 8-6-05
From CO2 Science Magazine, 15 June 2005
In an important new paper, Davis et al. (2005) analyze the elevation change (dH) of over 8.5 million km2 of the grounded Antarctic ice sheet interior (~70% of the total ice-sheet area) using ~347 million dH measurements derived from ERS-1 and ERS-2 ice-mode satellite radar altimeter data (with coverage extending to 81.6oS) for the period 1992 to 2003, after which they compare the observed elevation changes of ~1500 1o x 2o (latitude x longitude) regions, 22 major drainage basins, Berkner Island, West and East Antarctica, and the entire region of coverage (ROC) to estimates of concomitant snowfall derived from meteorological models.
The primary result of this exercise revealed, in the words of the five scientists who conducted the work, that "the vast majority of regions in East Antarctica are thickening, especially in the interior, while regions in West Antarctica exhibit both strong thickening and thinning trends." At the basin scale, as they continue, "dH/dt values range from 0 to +6 cm/year for East Antarctica, while there is substantial spatial variability in West Antarctica with dH/dt values ranging from -10 to +19 cm/year." Overall, they report that the East Antarctic ice sheet interior within the ROC is thickening at a rate of 1.8 - 0.3 cm/year, while that of the West Antarctic ice sheet interior is thinning at a rate of 0.9 - 0.3 cm/year. For the entire ROC, the 5:1 ratio of East to West Antarctic area coverage "causes slight thickening overall at the rate of 1.4 - 0.3 cm/year."
[...] There are many implications of these various observations that remain to be determined. At this point in time, however, we can safely conclude that the climate-alarmist claim of dramatic global flooding of earth's coastal areas in response to the melting of polar ice due to global warming has been thoroughly discredited, for during the period of time that they claim the planet experienced the warmest temperatures of the past two millennia, Antarctica experienced a net buildup of ice that actually removed water from earth's seas.
Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is to promote themselves as wiser and better than everyone else, truth regardless.
Global warming has taken the place of Communism as an absurdity that "liberals" will defend to the death regardless of the evidence showing its folly. Evidence never has mattered to real Leftists.
Actually the environmental extremists are eco-imperialists.
When I asked the author of Greenie Watch in an email why the right only seems to focus on green extremism (not the positives) while their own party in question seems to be carrying out their own form of extremism, his reply was:
I note on my Greenie Watch blog that I support things that DO help the environment but most that can reasonably be done in that direction does get done anyway. Everyone wants a nice environment.
Most Greenie fads do NOT help the environmernt (e.g. the global warming panic) and unfortunately it is only the conservatives who oppose the hare-brained element.
Again, correct as far as it will go, but I was hoping for something along the lines that would disprove Bush's record or delve into how green extremism is so overwhelmingly in the majority. Instead I hope to in the coming days and weeks focus on a new column titled "Opponents of the Environment," which hopefully will provide some new findings that have not already been discussed thoroughly.
