Don Bogard, research scientist and member of The Right Climate Stuff, TRCS, team, website: http://www.therightclimatestuff.com/. This is a clearly written discussion of atmospheric sources and sinks of carbon dioxide. It explains the contributions of CO2 by activities of mankind (cement, land use, fossil fuels).
Katharina Bochsler on Swiss Radio and Television, Schweizer Radio und Fernsehen (SRF): Zahlreiche Studien kochen das Konfliktpotential der Erderwärmung hoch. Sie prophezeien gewaltsame Konflikte und grosse Völkerwanderungen. Doch wissenschaftlich sind die meisten dieser Studien nicht haltbar.
Marc Morano, Editor of ClimateDepot.com blog a project of CFACT, Anthony Watts, publisher of wattsupwiththat.com Watts Up With That? The world's most viewed site on global warming and climate change: This book covers the history of climate, from the global cooling ‘coming ice age’ scare of the 70s to the ‘we have just a few years left to save the planet’ that characterizes the current global warming scare. Written in a light reading style, virtually every page is meticulously referenced with sources for the points he makes.
Dr. Willie Soon is an independent solar physicist at the Harvard-Smithsonian Center for Astrophysics who has been studying the Sun and its influence on the Earth’s climate for more than a quarter of a century. Polar bears are far less endangered by global warming than by environmentalists dreading ice melt. A good puzzle for polar bear science is to answer the question how polar bears survived during the ice ages, when ice covered coastal zones and large parts of the global ocean. Ice was piled miles deep on land, making it extremely difficult for eco systems to provide enough food.
Sebastian Luening, paleogeologist: Die Forsythie blühte in den letzten 30 Jahren immer später. Und das tat sie weil es im Februar und März immer kälter wurde. Das Klima wandelt sich. Aber nicht immer so, wie man es in der Zeitung liest. Wenn man nun über die letzten 30 Jahre (“Klima”) hinausgeht, so trifft man in den 1980er Jahren auf eine Phase, in der der Hamburger Forsythienstrauch schon einmal sehr spät geblüht hat. Das Klima führt ganz offensichtlich eine natürliche Eigendynamik.
William Happer, Emeritus Professor of Physics, Princeton University: Albert Einstein would almost certainly have been a global warming skeptic if he were alive today. Many distinguished, contemporary scientists are skeptics too. Most importantly, Einstein would have paid close attention to how well the establishment theory of global warming agreed with experiment. He famously stated: “No amount of experimentation can ever prove me right. A single experiment can prove me wrong.” The earth has done the kind of experiment Einstein had in mind. It has warmed at a much slower rate, two or three times slower, than models have predicted. To make matters worse for alarmists, no one knows how much of the relatively small warming is due to increased carbon dioxide.
Dennis Avery is an agricultural and environmental economist and a senior fellow for the Center for Global Food Issues: In a recent New York Times column, Nicholas Kristof misleads us about the awful history of Easter Island (2,300 miles west of Chile), whose vegetation disappeared in the cold drought of the Little Ice Age. In doing so, he blinds modern society to the abrupt, icy climate challenge that lies in our own future.
John Haldon, Professor of European History, Princeton, University: Grasping the challenges that climate change presents and evolving appropriate policies that promote and support mitigation and adaptation requires not only an understanding of the science and the contemporary politics, but also an understanding of the history of the societies affected and in particular of their cultural logic.
