Polar Ice Clouds Due to Global Warming

Here's an important bit of speculation about climate change and global warming. Polar ice clouds may be a symptom of climate change, according to Associate Professor Richard Collins of the University of Alaska-Fairbanks.

The reasoning goes something like this: carbon dioxide causes heating in the lower atmosphere and cooling in the upper atmosphere so these icy clouds could be a result of global warming.

The article goes on to say that these clouds were first noticed in the Arctic sky in the 19th century and have become more prevalent since.

My question would be, since no one really began to explore the north pole before the 19th century, how could anyone have possibly recorded them prior to that? And since there are more explorations of the Arctic now than there were in the 1800s, wouldn't that explain the increased sightings of these clouds?

The beauty of global warming theory is that nearly anything can be examined in such a way as to prove a link to climate change. The ability to use logic is not necessary, in fact, it's a definite hindrance.
