Low-lying Pacific islands not sinking | |||
2010-06-04 | |||
[Iran Press TV Latest] Geologists have found that global warming is not a grave danger to many low-lying Pacific islands, which are said to be growing instead of sinking.
Inhabitants of many low-lying Pacific islands have recently come to fear that their homelands might be wiped off the map due to rising sea levels. "That rather gloomy prognosis for these nations is incorrect," Associate Professor of Auckland University Paul Kench said. "We have now got the evidence to suggest that the physical foundation of these countries will still be there in 100 years, so they perhaps do not need to flee their country." Studies, however, suggest that the islands might not be inhabitable in the long-term and rising sea levels can threaten the livelihood of people living in Tuvalu, Kiribati and the Federated States of Micronesia.

#2 I tried to find the original article, but the best/quickest was this: The Earth's shape resembles an ellipsoid (its equatorial radius is about 21 kilometers (13 miles) greater than its polar radius) but it is not a perfect ellipsoid. Because of this resemblance, an ellipsoid is used to approximate the bulk of the Earth's shape, and departures from the ellipsoid are represented by the geoid elevation above or below the ellipsoid. The geoid can be as low as 106 meters (350 feet) below the ellipsoid or as high as 85 meters (280 feet) above. GRACE and Here's an example of how it works. The two GRACE satellites are traveling in space, both 500 kilometers above the earth. As the front satellite approaches an area of higher gravity, it will be pulled toward the area of higher gravity and speed up. This increases the distance betweenthe two satellites. As the satellites straddle the area of higher gravity, the front satellite will slow down and the trailing satellite will speed up. As the trailing satellite passes the area of higher gravity, it will slow down and the lead satellite will not be affected. As the satellites move around the Earth, the speeding up and slowing down of the satellites will allow scientists to measure the distance between the two satellites, and, therefore, map the earth's gravity field. Is this a great planet, or what? |

#1 If you believe everything I read, the effect of gravity on satellites has been used, by measuring the minute variations in distance between them, to measure the local gravity of earth. From this, they conclude the local sea level varies by over 200 feet. I think it was 150' low to 75' high, but it may have been the other way. Less gravity = higher sea level. When they show me a study that proves that CO2 reduces gravity, then I'll move to higher ground. |
