[NSRCA-discussion] What a difference a year makes

Wed Mar 20 16:45:25 AKDT 2013

Actually stopping has nothing to do with a stall, it is when the wing exceeds the critical angle of attack. That can happen at very high speeds if the plane is heavy enough or you pull the stick back hard enough. 

Our pattern planes are too lightly Wong loaded to induce a stall at cruise speed.

>>> This is where we have a huge ideological schism. You appear to think that science and data have political leanings. I do not. Certainly there is biased science, as is evidenced by the tobacco companies that found smoking to be harmless. And as a scientist you certainly understand that there is always disagreement, but one need to look at the preponderance of research and data when drawing a conclusion. In this instance that body of evidence comes down squarely in favor of global warming/climate change. To attempt to dismiss it on a political or ideological basis is less than what I would expect from a trained scientist.
>>> 
>>> FWIW, I agree about the irony of MTBE, as well as the whole host of other fuel oxygenates, causing unforeseen consequences. Yet I draw a completely different conclusion. Fuel oxygenates have been unequivocally proven to reduce emissions and lessen pollution. To say that the decision to implement their use is flawed because of that unforeseen consequence to me is not a valid conclusion. Clearly the issue was improper containment systems which were addressed in the requirement to replace all USTs with either Plasteel or double-walled fiberglass. The problem is not MTBE in fuel. The problem is leaking tanks. The new regulations have resulted in a drastically reduced number of unauthorized releases.
>>> 
>>> On balance I think it can be argued that the environmental damage caused by MTBE is significantly less that the impact of severe air pollution. So I guess it is a lesser of two evils argument in a way. However, the point remains that what was done is far better than having done nothing. Certainly MTBE has caused significant impact, especially to the water supplies of particular cities such as Santa Monica. But again, the widespread and chronic negative effects of air pollution in my mind still justify that decision.
>>> 
>>> I agree that we must always examine science with a critical eye, but at some point the evidence is clear. Where politics comes into it is when we try to determine what to do about it. But if we continue to dismiss science and make people distrust it based on politics or dogma then I think that is a huge disservice to society. As I have said before. I'm willing to debate all dat long about what we can or should do about global climate change, but if we try to address the issue by pretending it is a hoax then I think we are all in trouble.

I spent much of my professional career cleaning up MTBE, which was forced on the petroleum industry despite warnings it would do more harm than good.  Just one example of a politically driven knee jerk reaction that despite intentions of helping the environment ended up harming the environment.

The main reason that the term has been changed was due to fact that many deniers made silly comments like "well it snowed here today, so much for global warming". The more precise term is in fact global climate change. That is being fueled by the increase in average global temperatures which are drastically affecting the climate. It is also worth understanding the difference between climate and weather.
