Here in Canada, the police can arrest you for refusing to identify yourself. A driver's license does that, but any other way would work. You must have a similar law down there, too. It sounds like the guy was being a jerk, and the cop used that excuse.
Because sunlight affects other processes in the biosphere. It seems to me that months of darkness at 60 degrees F might promote mold and the like that would kill trees and other plants.
The evidence you cite is for deciduous trees in sunlight and cold temperatures--a very different scenario.
Then there are other factors to consider. Even in the Summer when there is light all day long, the light is generally sideways, not from above. The trees on the edge a forest would shade those on the inside all day long.
And trees require darkness every day. They actually grow in the night using the sugars produced during the day.
It just seems lazy to assume that Florida temperatures in the Arctic would simply mean Florida conditions and vegetation would exist in the Arctic, which is the speculation I have seen. There doesn't seem to be fossil evidence to corroborate it.
Continental drift occurs much too slowly to have the effects indicated by the core samples in this study. Over the last 55 million years, the arctic has been about where it is now.
Also, it is ridiculous to suppose that the region moved towards and away from the pole to match the wild temperature fluctuations revealed in the data.
Some of the other speculation I have read on this story is also suspect to me. Namely, trees ringing the Arctic Ocean. I find it difficult to believe that trees would flourish with long periods of darkness annually. But I could be wrong here; there are some plants native to the region today--but they are dormant for most of the year.
Dr. Lambert has made a hobby of following DDT opponents' crazy theories, as well as the anti-global-warming crowd, and the Big Money that makes both possible. For a compact overview of DDT falsehoods, check out DDT ban myth bingo.
For those unaware of Canadian politics, the government faces a non-confidence vote Monday or Tuesday. It is expected to fall and call a December election.
For campaign reasons, the government has announced a flurry of new spending over the last week, most of which is expected to never materialise, whether the governing party wins again or not.
What if the stack is very large, for instance? Is it still obvious that the pyramid is best?
Consider a similar problem, that of packing squares in a rectangle. When the rectangle is small, it is obvious that the best way is to pack them together starting from one corner, leaving a little wastage on the opposite two sides. It seems strange, but it is true, that when the recangle is very large, this strategy is not optimal. More squares can be packed when they are not packed in such a regular pattern.
This is the main difficulty with proofs of this type. It can be easy to prove that a given strategy is not optimal, but not so simple to show that no better strategy can exist.

I wanted to write Verizon Wireless directly to thank them for providing us with such excruciating entertainment.
Funny thing...The link now leads to a page to purchase new Verizon products instead.
Does anyone at Verizon begin to understand the nature of this public relations fiasco yet?
