William Happer, Emeritus Professor of Physics, Princeton University - Interview about the topic of man-made global warming. Great damage has been done to the reputation of all of science by the global-warming frenzy of the past few decades. Twenty years ago, supposedly expert scientists solemnly declared that our children and grandchildren would not know what snow is. A few weeks ago, Washington, DC, struggled to dig out of three feet of snow, a record in many locales.

CO2 Coalition, William Happer et al.: Atmospheric water, H2O, as vapor and clouds, is by far the most important source of greenhouse warming of the Earth's surface. Atmospheric CO2 also contributes to warming but much less than H2O. More CO2 will cause some additional warming, both directly and with amplification by feedbacks, which are still very poorly understood. The earth's temperature is affected by many other factors. Among these are solar activity, atmospheric and ocean circulation patterns, volcanic activity, etc. We are persuaded that the net effects of increasing CO2 will be very good for the world, especially for people.

CO2 Coalition, William Happer et al.: The fraction of the beneficial molecule CO2 in the current atmosphere is tiny, about 0.04% by volume. This level is about 30% larger than pre-industrial levels in 1800. But today's levels are still much smaller than the levels, 0.20% or more, that prevaied over much of geological history. CO2 levels during the past tens of millions of years have been much closer to starvation levels, 0.015%, when many plants die, than to the much higher levels that most plants prefer.

Larry Bell: "Climate change policy is about how we redistribute de facto the world’s wealth." - IPCC official Ottmar Edenhofer. The larger issue has to do with just how many of those who stoke the global warming alarm fires have real confidence in that “science.” So let’s briefly review just a few candid comments that some of them have offered on this topic.
