Dr. Evil is still fighting the good fight on the "global warming" issue. Apparently tired of being characterized as a "flat Earther" or "Holocaust denier" he returns fire:
Al Gore and his crowd are Goebbels reborn, in my view. And global warming is their path to power. Only carbon (and its pushers) is the new Jewish threat.
I agree with this assessment. Every word of it. I, too, am greatly annoyed with the absence of adult reasoning and conversation, even civility on this issue.
Allow me to republish a post from August 2004, when temperatures were well below normal.
Question 1: Is the Earth getting warmer? Such a question needs clarification. How is this measured? Over what period of time? The weather has many cycles, day and night, winter and summer, El Nino, perhaps the eleven year sunspot cycles. But what we’re talking about here is long term, more on the order of many decades at least. We are not talking about millions and billions of years, when as the sun grows, the earth will literally be fried.
So is the Earth getting warmer in this stated timeframe? It may well be, which is to say it also may not be. The difficulty lies in our ability to measure average temperatures and the relatively brief amount of historical data available, little more than 100 years’ worth. The accuracy of the earlier historical data is also suspect, given the technologies available at the time. But the data would suggest a warming trend, though some of the most recent research seems to suggest otherwise.
For the sake of argument, let us postulate that some warming is taking place, though probably less than some have claimed.
Question 2: What’s causing this? The standard answer is the increased accumulation of greenhouse gases, notably carbon dioxide, largely caused by the burning of coal and oil.
Carbon dioxide levels have risen, making the atmosphere better able to retain the heat from sunlight. This, too, may well be, but here there are so many other factors that could be far more significant. That atmospheric carbon dioxide levels are rising was known decades ago, but at that time, the fear was global cooling, leading to another ice age. The scholars of that era clearly saw other factors as more serious even then.
One such factor is the sun itself. We have only acquired the ability to measure the sun’s output in the last 20 years or so, and some of that data suggests the sun itself is getting warmer. The sun may have some sort of cycle, like its sunspots, and we’re in an ascending slope of that cycle.
Another factor is volcanic activity that thrusts millions of tons of dust into the atmosphere. Major eruptions have clearly affected the weather worldwide.
Finally, consider clouds. We have no working models or theories that predict overall cloud cover and densities. Do clouds actually form more readily when the Earth warms, as some data suggest, as a natural correction? God only knows for now.
The intellectual bus stops here as we are largely in speculative territory here. But again for argument’s sake, let us postulate that carbon dioxide et al is indeed the cause of the stipulated increase in global temperatures.
Question 3: Is global warming better or worse for mankind?
Why, bad, of course, we are told. The polar ice caps will melt, flooding coastal areas and cities around the world. This will be gradual of course, not a tidal wave or flash flood, at most about three feet by the year 2100. [2006: Now they're saying 20 feet!]
The increase in temperature in we are talking about is an average, but not uniform. Most of the observed increases are the result of warmer nights and warmer winters, not still hotter afternoons in the tropics. I’m for that!
Finally, carbon dioxide is part of the carbon cycle of life. We ingest carbon and hydrogen, inhale oxygen, exhaling water and carbon dioxide. Plants do the reverse, and there is no question that the plant kingdom is responding to these higher levels of carbon dioxide. This is in fact critical to supporting our population levels.
So the only bad news is the sea level rise, at most a very manageable 3 inches per decade, and some say much less. This is not a crisis by any means, especially given the many positives. But again for argument’s sake, let’s assume it is.
Question 4: Can we fix it?
Those who embrace the Kyoto treaty assume so, that reducing greenhouse gas emissions will make things go back the way they were. This is an unwarranted assumption.
Many physical processes are not reversible, particularly thermodynamic processes. If you stroke a piece of iron with a magnet, it acquires some magnetism of its own. Stopping the process does not make the iron revert to its prior, non-magnetic state. Similarly, if you melt an ice cube, putting the water in the freezer does not re-assemble the water into its original cubic shape.
We have no models or theories that can begin to assure such an outcome. The “damage” may already be done. To severely cut our standard of living, which will no doubt entail casualties and personal trauma, requires a much, much higher expectation of success, especially for a problem that eludes quantification and analysis.
Question 5: What should we do?
Mostly, be an adult. Evaluate the situation, the choices available, and the costs of each choice. This last step is seldom performed by environmentalists. They felt it was important to ban DDT even at the cost of millions of malaria deaths. DDT is powerful; that’s what makes it useful. But it can be handled safely, just like so many other substances.
Until we truly understand the problem and the alternatives, we have no moral right nor any moral obligation to impose Kyoto or similar constraints on a free people. Like so many other evils of our age, the cure is likely worse than the disease.
