The Amazing Rehab of Chicken Little: From Laughing Stock to Climate Change Superhero
This very silly article reports on the disappearance of an island in the Bay of Bengal due to rising sea levels. The article notes that global warming is the cause of the submergence of this island however the author dishonestly characterizes it’s disappearance as seemingly precedent setting and sudden. The following paragraph perfectly captures the typically shallow thinking of most traditional media, global warming, street preachers. Trembling fretfulness and embarrassing displays of remedial knowledge of their subject matter tend to characterize their reporting.
“Rising seas, caused by global warming, have for the first time washed an inhabited island off the face of the Earth. The obliteration of Lohachara island, in India's part of the Sundarbans where the Ganges and the Brahmaputra rivers empty into the Bay of Bengal, marks the moment when one of the most apocalyptic predictions of environmentalists and climate scientists has started coming true.
As the seas continue to swell, they will swallow whole island nations, from the Maldives to the Marshall Islands, inundate vast areas of countries from Bangladesh to Egypt, and submerge parts of scores of coastal cities.”
There are just a few problems with the author’s characterization of the Atlantis like disappearance of this island. For starters, it is not the “first time” rising ocean levels have submerged land masses, and in tone and implication the article is outrageously misleading. The most recent process of submergence of low elevation land masses began as much as 18,000 years ago and the most dramatic rate of rising sea levels and thus the most dramatic rate of loss of the earth’s dry land, and certainly the island in question, Lohachara Island, occurred a long, long time ago
As almost every geologist and archeologist in the world knows, over the last few hundreds of millions of years, there has been about a 200 meter difference between the high and low water marks of the earth’s sea levels! These endlessly repeating cycles of changing sea levels roughly correspond to the similarly natural cyclical fluctuations in the earth’s climate. At the height of any particular ice age the sea level is generally at it’s lowest because more water is bound up in the form of land based ice caps. At the peak of warming trends that always follow ice ages, like at the present time, sea levels generally are at their highest because ice caps have melted back into the oceans.
The earth’s sea level has been rising for the last 18,000 years. That’s right – 18,000 years! Furthermore, up until about 6000 years ago sea levels were increasing at an average rate of 17.5 millimeters per year or about 1.75 meters each century. To help put that into perspective, 18,000 years ago the sea level of the earth was 120 meters (over 300 vertical feet!) lower than it is right now.
Over the most recent 6000 year period, the rise in the earth’s sea levels has been very slight; it has only risen about 5 to 7 meters in the last 6000 years (comparing apples to apples, the average rise in sea levels over that period of time was 0.1 to 0.3 millimeters a year). However the 6000 years preceding this period, the earths sea levels rose over 100 meters!
We are regularly assaulted with the frenzied warning clucks and chirps of the global warming Chicken Littles, who point out that over the last 100 years the annual rate of rise in the earth’s oceans has increased to 1 to 3 millimeters per year (remember –for the period between 6000 and 12,000 years ago the average annual increase was 17.5 millimeters per year). If you split the difference and assume the projected rate for the next 100 years is 2 millimeters per year then the rise in sea levels in 2100 would end up being in the neighborhood of 20 centimeters, or one fifth of one meter, or about 8 inches.
According to the Al Gore global warming crowd, we are supposed to believe that this purported change in the rate of increase in our oceans levels is primarily due to nefarious human activity including the grandest of sins - using fossil fuels. Once you buy into this hoax, you are then naturally expected to embrace their crazy package of economically self destructive carbon reduction remedies.
To Al and flock, I ask your indulgence while I try to figure a few things out. OK - let me get this straight.
1.For the last 6000 years the earths sea level has hardly increased – only 5 to 7 meters.
2. Ok – and for the 6000 years before that, the earth’s sea levels increased over 100 meters which is 20 to 25 times greater than the most recent 6000 years.
3. Ok – and that extraordinarily fast rate of rise in the earth’s sea level occurred before humankind had basically even invented the wheel – point being that humans had nothing to do with it.
4. Ok – now we have some pretty thin evidence, meaning only 100 years of trended data compared to 18,000 years of trended data, to suggest that the earths sea level might rise at a rate of 1 to 3 millimeters per year which, is a slight increase, but still pales in comparison to the 17.5 millimeter rate that the earth experienced for the period 6000 to 12,000 years ago when human generated CO2 was not at all in the picture.
5. Hmmmm… well Al, it seems to me that the feared trend of sea levels increasing up to a maximum of 3 millimeters per year, is really a drop in the bucket compared to the 17.5 millimeter per year increase that the earth experienced for 6000 years.
6. Finally Al, how do you come to grips with the following scientific consensus?
“However, over most of geologic time, long-term sea level has been higher than today (see graph above). Only at the Permo-Triassic boundary ~250 million years ago was long-term sea level lower than today.”
So, it strikes me as just plain nutty that we humans are talking about experimenting with changing the earths climate to suit our interests, knowing that throughout most of earths history, sea levels have generally been much higher than they are today, and thus can assume that they will once again be so in the future.
We know that the earth has experienced repeated cycles of naturally occurring glaciation and warming, and repeated cycles of naturally occurring decreasing and increasing sea levels. Considering the fact that all this has gone on for hundreds of millions of years with absolutely no human footprint what so ever, what on earth makes us think that for this latest cycle when we finally came upon the scene, we either should or can change that pattern?
The radical global warming interventionists personify a typically self important human response. Even though we humans were almost completely absent for the vast history of these changing climatic and sea level cycles, we finally arrived on the geologic scene and promptly pronounced ourselves responsible for global warming and thus, for adversely changing the climate and all that goes with it. Good grief!
The sky is falling! Do something! Who ya gonna call? Call Big Al and the Littles (as in Chicken). But beware of their terms. Their fee is exorbitant, their fix is impractical, their product is theoretical, and worst of all, there is not even a hint of any kind of warranty if their carbon reduction taxes don't produce results.
Don’t believe the intellectually lame compost that the mainstream media shovels at you on this subject (as a matter of fact on a whole lot of subjects!). Do your own homework. Exploit the web. Get the facts!
Yes, we need to move purposefully away from our reliance on fossil fuels. Not because of global warming or rising sea levels; the climate will change regardless of what we may attempt to do about it. We need to move to alternative energy in order to lessen our reliance on oil provided by increasingly hostile nation producers.
