To claim that the "average normal" temperature of the ocean and atmosphere has risen 1 degree over the last few decal or century is simply not realistic. It is hard enough to determine the average temperature of a Wal-Mart Super Store with people activity over a month!!! You are going to have more than a few degrees different from different part of Wal-Mart over a month with cooling and warming change of the day and night. You can only control with huge AC/heater within a few degrees in the Wal-Mart "weather" system which is so much smaller and simpler when compare with the earth. How it is possible to determine a small change in the huge global weather system is beyond me. Yes, while the earth is turning constantly and cycling and receiving heat from the Sun.
What about the ocean level risen a few millimeters? How would one even set the original level and with all the wave, tidal change and season change?
Where and how would one determine the earth's "normal average" temperature? Of course one has to determine what normal and average first? But, still where and over how long a period do we determine the normal average temperature? How long ago was the thermometer invented? A few hundred years? Yes, we have to guess, estimate the temperature for the earth a hundred years ago. There is no accuracy there! And before the thermometer was invented, there was NO temperature, there was no degree. There was only hot, cold, too hot and too cold. OK there was the just right!
Next, one must somehow determine and point the finger and say:â Human caused global warming." Do we really know the cause of a very small change of such a huge weather system?
I am not even going to argue that the earth may be warming. However, do we know the sun that is NOT causing it? Or whatever we proposed to do about global warming would even have any effect, given that human have NEVER done anything to the earth that are BOTH long term and global in history.
Can anyone name a few "things" that human did, to the earth, that have been proven to be long term and global?
That is, whatever the human did, it must affect a very large area, let say a few thousand square miles and the effect last for at least a few hundred years?
None, I cannot of thing of a thing that human has done to the earth that are both long term and global.
The Pyramid in Egypt may have been there may be a few thousand years, but it is not global. The Great Wall of China have existed a couple of thousand years and is long and narrow for a few thousand mile but still it is not global. All oil spills in history in the ocean or land are not global and not long term. You cannot tell it ever happen after, let say 30 years. Nuclear accident in Chernobyl may last a thousand years, but it affects a very small area but not global.
Remember the oil field burning in the first Iraq war? Give it another 20 year, or 40 year, no one can even tell it ever happened except from history book.
Remember the atomic bombs, nuclear bombs test; they are all local and not global.
This global warming hysteria is Chicken Little: "The sky is falling! The sky is falling".
