This morning, the Wall Street Journal published an Op-Ed by Dr. William Gray titled "Hurricanes and Hot Air". In it, Dr. Gray argues that there is no link between global warming and the recent "increase in major hurricanes".
Unfortunately, this piece has several inaccuracies and omissions. Let me clear them up.

I’ve been reading a great book called Uncertain Science… Uncertain World by Henry Pollack – a readable and engaging discussion of decision-making in the face of uncertainty. Pollack argues that decision-makers use uncertainty as an excuse for inaction, when in fact it should be a stimulus for creativity and progress.
How sure do you have to be that something will happen to act on the possibility?

Last week in our Suggestion Box we got this question:
I’ve compiled a NCDC state by state average temperature map and trends from 1895 thru 2006. 1998 was the warmest year, but years since then are showing either the same as 1998 or cooler in most states. How can I explain to people why average temps haven’t been warming EVERY year since 1998 instead of going up and down?
This is a good question, and one I get fairly often, so let me try to explain.
In reading the news this week, I was struck by how many reports there were from around the world of problems related to global warming. Here’s what I found:
Warming poses threat to Chesapeake
Washington Post, July 20, 2007
China says climate change drying up major rivers
Yahoo! News – Reuters, July 16, 2007
Warming may bring hurricanes to Mediterranean

Glacier in retreat
New York Times, July 17, 2007
Climate change threatens Italy’s Po River delta
Yahoo! News – AFP, July 17, 2007
I also came across an interesting article in the Washington Post about by a guy who went around the world visiting places affected by global warming. The descriptions are, um, chilling.

Stephen Colbert once quipped, "It’s not that I don’t believe in climate change, it’s that I don’t believe in climate. Have you ever heard anyone say, "How’s the climate?" No! They say, "How’s the weather?""
People often confuse climate and weather. They wonder how scientists can reliably predict climate 50 years from now when they can’t predict the weather a few weeks from now. The answer is that climate and weather are different, and it’s easier to predict climate than weather.

In March of this year, British TV Channel 4 aired a 72-minute diatribe called "The Great Global Warming Swindle". The program is filled with old data, data taken out of context, data misattributed, and general misinformation, and at the time it aired we thought it not worth responding to.
But people keep mentioning it, so here are the program’s main arguments and why they’re wrong. Now the next time someone brings this up, you’ll have the facts to give them.
