Dennis Hedke, geophysicist: Are the world's coastal cities destined to be inundated as ice melts at the top and bottom of the planet, causing the oceans to rise? Climate alarmists argue this will be the case if policymakers do not adopt draconian measures to eliminate fossil fuels, especially coal, which produce carbon dioxide emissions that, they allege, cause harmful global warming.

Scott Denning, Director of Education, ESMEI, Atmospheric Science, Colorado State University: The science of Man-made Climate Change is simple to explain, serious to our way of life and solvable. We don't have to choose between progress and prosperity. Many people think: "Our well-being is based on stuff we extract from the ground." When we stop burning coal, will our descendants shiver in the dark? "We create our well-being through crativity, ingenuity, and hard work." The future is bright.

Bryan Leyland, power systems design, mechanical engineer: Most people who believe in dangerous man-made global warming appear to be confident that the world will soon start to warm again and in 20 or 30 years time the predictions of the climate models will have proved to be correct. Many also tell us that we will have reached the 2° "tipping point" where, they claim, irreversible climatic changes will occur by 2050.
