Dedicated to the balanced discussion of global warming
National Post – January 26, 2007
I wouldn’t be able to say that this is a balanced discussion of global warming if I didn’t bring up both sides of a given argument. I think that it is you, the readers, that need to decide with an open mind the validity of the arguments put before you. I will also give my editorial assistance to influence your thinking to my side – we don’t know enough and need to spend millions of dollars to figure this out before we invest billions (trillions) of dollars to solve a problem that may not be solvable.
This article concerns the global warming on Mars. A few days ago, I cautioned Mr. Al Gore from making comparisons to other planetary bodies (click here to read). There are simply too many variations from one planet to another to say that occurrences on one will be the same on Mother Earth.
In this case, the author of the article tries to explain that Mars is enjoying a global warming, gives specific observances to support this, and then proposes a theory to explain the change. He then goes to make the corollary with Earth and explains that the same thing is happening here.
I do believe that the big difference in comparing planetary bodies is pointed out in the article: oceans. Since neither of our heavenly neighbors has a large ocean of fluid that is very near its solid, fluid, and gaseous state in the temperature range existing on the planet, there are limited climatic things we can learn from these two planets (or any planets in our solar system). There are surely geological things we can learn about other planets, but I think their value as a climatic model is tenuous at best.
Global warming extends to Mars, where the polar ice cap is shrinking, where deep gullies in the landscape are now laid bare, and where the climate is the warmest it has been in decades or centuries.
With each passing year more and more evidence arises of the dramatic changes occurring on the only planet on the solar system, apart from Earth, to give up its climate secrets.
Dr. Habibullo Abdussamatov at Saint Petersburg’s Pulkovo Astronomical Observatory. Pulkovo: “Mars has global warming, but without a greenhouse and without the participation of Martians,” he told me. “These parallel global warmings — observed simultaneously on Mars and on Earth — can only be a straightline consequence of the effect of the one same factor: a long-time change in solar irradiance.” … “It is no secret that increased solar irradiance warms Earth’s oceans, which then triggers the emission of large amounts of carbon dioxide into the atmosphere. So the common view that man’s industrial activity is a deciding factor in global warming has emerged from a misinterpretation of cause and effect relations.”
Heated greenhouse gases, which become lighter as a result of expansion, ascend to the atmosphere only to give the absorbed heat away.
The real news from Saint Petersburg — demonstrated by cooling that is occurring on the upper layers of the world’s oceans — is that Earth has hit its temperature ceiling. Solar irradiance has begun to fall, ushering in a protracted cooling period beginning in 2012 to 2015. The depth of the decline in solar irradiance reaching Earth will occur around 2040, and “will inevitably lead to a deep freeze around 2055-60” lasting some 50 years, after which temperatures will go up again.
Dr. Abdussamatov concluded. “A global freeze will come about regardless of whether or not industrialized countries put a cap on their greenhouse- gas emissions.”
