Free speech is something we should all support. But that doesn't mean that everyone's opinion is entitled to equal weight. Brian Bolig's Jan. 17 letter to the Harrisburg Patriot-News says that climate change is a hoax. He cites as his proof the fact that Hannibal used a pass in the Alps that is snow covered today. He doesn't name any scientists who support this "proof" of a hoax.

As far as I know, there are none. According to Bolig, everything in this world is politicized.

It seems that way, if all you watch is Fox News Channel and MSNBC. If Mr. Bolig would widen his search a bit, he will discover that the overwhelming scientific consensus supports the position that man is responsible for a substantial portion of our gradually warming climate.

According to the World Meteorological Organization, seven of the warmest years on record have occurred in the last 10 years. The consensus prediction is that the Arctic Ocean will become navigable in about 30 years. The snows of Kilimanjaro will be gone in less than a decade.

Mr. Bolig and others such as Rush Limbaugh can always find a lone gadfly scientist who will support their silly position. Meanwhile our earth continues to warm and our window of time to act continues to close.
