Sea Level Rise
As usual, the rate of change is now seen to be faster than earlier predictions.
The deniers are out in force trying to persuade anyone and everyone that this is not really happening, but the basic measurements say otherwise. I guess fundamental scientific measurements of sea level are part of a vast left wing conspiracy, oh and death panels, too.

Major cities at risk from rising sea level threat

The Scientific Committee on
Antarctic Research (SCAR) calculated that if temperatures continued to
increase at the present rate, by 2100 the sea level would rise by up to 1.4
metres — twice that predicted two years ago.
|
Even if the average global temperature increases by only 2C — the target set
for next week’s Copenhagen summit — sea levels could still rise by 50cm,
double previous forecasts, according to the report.
|
The IPCC report predicted that the melting of ice sheets would contribute
about 20 per cent of the total rise in sea levels, with the majority coming
from the melting of glaciers and the expansion of the water as it warms. It
said that it was not able to predict the impact of melting ice sheets, but
suggested this could add 10-20cm.

Combating Global Sea Rise
Not sure if anyone has considered this before, but there are a number of areas below sea level that isn’t too far from the ocean where a simple canal could be established to allow water to flow from the ocean to fill some deep areas on dry land and help offset global sea rise. Areas such as the Qattara Depression could be filled by ocean water. A simple cannel that would hardly support a boat could enlarge itself through erosion to allow for a larger flow of water to fill this natural depression.
Africa is in the process of breaking apart with low-lying areas that will be filled by the sea at some point in the future, and those who depend on water today are struggling because of these geographical changes and the lack of water. By establishing a canal to fill these low-lying areas with sea water, this will result in more rainfall in the region and help to establish better farmland.
Another example of a low-lying area is Israel, where the Dead Sea is shrinking. A canal from the sea with a dam could regulate the height of the Dead Sea to a desirable level.
Also, water from Lake Erie could be redirected to the southwest to refill aquifers.
