Think of a cat stalking a bird, the climate expert said. You see the cat tense, and creep towards the bird. Now picture only the bird's nervous system, and with that information, try to model the cat stalking. That is the equivalent of a global climate model.</p><p>The expert also commented on how information-age thinking has negatively affected science writing. He noted that when he was in school you were taught to use a slide rule, and in using a slide rule you had to have an idea of what the result would be. Nowadays people just grab an algorithm off the shelf and use it, without any thought about what kind of result they will get. He pointed to the trend in articles in leading peer-reviewed journals such as <em>Science</em> and <em>Nature,</em> which use numerical values out to several decimal places, most of which are wrong.</p><p>The scientist ended by asking the following scientific question: In the past two and-a-half billion years of the Earth's oxygen atmosphere, there have been only two climate states--one glacial and the other interglacial. In that time, the Sun's output has increased by 30 percent, yet the temperature has only increased and decreased only a small amount over the period. So how can a mere 0.4 percent of man-made CO2 now be catastrophic?</p><p>Think about that the next time you hear Al Gore talk about global warming, or you read the next big climate change scare story.</p></div></body>
