Tom Wysmuller, forecasted weather at Amsterdam's Royal Dutch Weather Bureau after studying meteorology at NYU and Stanford. Worked throughout NASA and its Directorates before, during and after the Moon Landings. In 2016, he was the featured Sea-Level speaker at the World Congress of Oceans in Qingdao, China. Lecturer at Colderside.com. His research shows that man-made carbon dioxide is not anywhere close to being the leading cause of climate change. There is no such thing as man-made global warming or man-made climate change. It is a ruse to control the world's use of fossil fuels. Strictly a political action to control economies and establish who rules the world.
Alex Pope, engineering mechanics, NASA: He focuses on past climate changes and explains that they are dependent on cycles of natural ice accumulation and melting in the polar regions. He provides explanations of the physics. These past climate changes have always been within certain bounds. Today's climate change is within these bounds. Man-made carbon dioxide plays a very minor role.
Don Bogard, isotopic and nuclear geochemistry: Today, when many are concerned about the Earth possibly over-heating through greenhouse warming, it is worthwhile to look into the not very distant past when the Earth over-cooled. Most people have heard of the Ice Age but probably know very little about it. Some may remember climate scientists in the 1970s expressing concern that Earth may be entering a new ice age, because of growing evidence that Earth was cooling (in spite of growing atmospheric carbon dioxide of CO2). What was the ice age, why did it occur, and is it now in our past, or also in our future?
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.
