An exaggerated truth

[bluemingidiot]

The 2006 film, An Inconvenient Truth, suggested that the sea would rise up to 20ft "in the near future" as the ice in Greenland or Western Antarctica melts.

"Records and research show that sea level has been steadily rising at a rate of 0.04 to 0.1 inches per year since 1900. Since 1992, new methods of satellite altimetry (the measurement of elevation or altitude) indicate a rate of rise of 0.12 inches per year."

This should suggest about a 1.20" rise over the last ten years. Again, a small portion of this rise would be accounted for by trash dumping, ships sinking, North Korean rockets, Chinese military ocean bases and Muslim pilots crashing jets in the oceans.

So, at present rates, around 2,100 AD the oceans will be up about a foot.

More significant to me than a rise in ocean levels is subsidence of land mass.

Because of the relentless increase in population more and more water is pumped out of the ground. That makes the ground level subside. That makes coastal populations more susceptible to flooding. Why don't Global Warmers ever talk about land subsidence?

Up here we're still going up from the last iceage, don't forget entire islands have sunk form having the gas removed from under them, and some oil fields in the north sea have dropped over 100m since pumping began, that would be pretty impressive under a city.

As to land subsidence, it's localised, a big issue in some deltas is the lack of sediment comming down due to water management and dams, also causing subsidence.

The Mississippi River sends 150 million tons of sediment into the Gulf of Mexico on a yearly basis.

Also known formerly as "topsoil".


Before I'd be overly concerned with the so-called 'global warming' melting the glaciers and icecaps around the world,

or subsidence causing cities to sink into the muck that they were built on, I'd be a tad more worried about how are

we going to feed the world when we run out of dirt to grow our food in . . .  just sayin.


"The estimate is that we are now losing about 1 percent of our topsoil
every year to erosion, most of this caused by agriculture."

I live where 3 tectonic plates meet in the ocean just off shore. In some parts the land is subsiding. In others its lifting. If there is an earthquake, it can be quite a sudden change. On average though the sea is gaining about 2 tenths of an inch per year at the worst places so far.

Hopefully the world warms and rich, previously unused top soil in Alaska, Canada, Greenland and Siberia can be used to grow crops.

A lot of people are thinking along the same lines but I'm afraid I have to tell you something disappointing.  Unfortunately, there isn't any rich topsoil, let alone any topsoil to speak of in those places in the far north.  It's permafrost (permafrost is muddy frozen peat) and tundra (a desert of rock with lichens growing on it).  The topsoil that was there long before the last ice age started all got ground up and bulldozed to the south by the growing glaciers that ended up covering most of the northern hemisphere.  When the glaciers receded they left the good topsoil behind in the south and mostly rock in the north. 

If you do some research about the topography and geological conditions in the north you will discover that it is basically all a frozen barren desert of pulverized rock with only a few inches of organic media (if any at all) on top of the rock (mostly acidic peat and lichens).  Just south of the Arctic circle the rock is mostly covered in deep black water with rafts of muskeg peat floating on top.  None of it is suitable for growing crops on. 

If the climate warms up enough to grow crops up there the organic material that does exist will need to be amended with the addition of billions and billions of tons of suitable growing media that would need to be taken and transported from elsewhere in southern regions, and the water will need to be drained and redirected for irrigation.  It might be possible to do something like that in another 200 - 400 years from now with the development of technology and infrastructure that can handle such a massive enterprise but it's not something that mankind is capable of doing in the immediate future.   Right now it's not even possible to build any solid infrastructure up there.

I would fear that if Alaska, Greenland and Siberia became warm enough to grow a substantial amount of crops, that those of us in the US and further south would find ourselves living in deserts.

[bluemingidiot]

Possibly, but moisture that was previously locked in ice will be available for evaporation and condensation.  Maybe instead of rhubarb and cabbages you might be growing bananas and papayas.

I believe the earth is constantly changing-I call it Global Chaos. It might become warmer and more tropical, areas that are underwater might emerge and areas that are emerged might sink. The oceans will rise and fall, temperatures will fluctuate always. The important part is that people are adaptable...

And therein lies the key.... and the heart of the problem with those who are inflexible in their promotion of global warming as being man-caused only.

There's an agenda that is being pushed on the rest of us to enable them to continue in the lifestyle and pattern that allows them to do so, as long

as carbon credits are exchanged.  IOW, do as I say, not as I do, because I can be excused to do so, as long as the guilt of polluting is abated by purchasing

or exchanging a form of currency that allows me to do it.  But the rest of you little peons are going to have to pay for it....ahhhahahahahahahaha!!!!!

I think you have a valid concern.  It's possible that could happen depending on location and terrain, however there's also a 50/50 chance that many places in the south could become saturated and turn into steaming lakes and flooded swamps due to daily warm rain.  At this stage it's all speculation about what might happen in given areas and I think the only thing that is a sure thing is that if it does get that warm nothing anywhere will be the same as it was.  As Melissa pointed out though, the important thing is that humans are adaptable, probably more so than the majority of other living things, and humans will tough it out come what may.
