Stephan Savarese, research engineer. President of Sauvons le Climat, Saving Our Planet: https://savingourplanet.net: Whatever the reasons for climate change, it's here and it's big. I name it Climate Transition because Climate Change has become a political issue. Showing pictures of isolated cold episodes in narrow regions of the world is picturesque, but cannot change the accurate, revised, precise statistics, which show that global warming has accelerated (at least) fourfold within the past fifty years, at a rate surprisingly fast and chaotic. As a consequence, ocean level rise, which had stabilized over the past five millennia at 1 mm/year, is on the verge of crossing the 5 mm/year mark, due to accelerated sea water thermal expansion, plus continental glacier melting.
Sidney Bernsen - Nuclear Engineer, Former Chief Nuclear Engineer for Bechtel Power Corporation Resumé
Sidney Bernsen - Nuclear Engineer, Former Chief Nuclear Engineer for Bechtel Power Corporation Nuclear Power Plants are currently too costly in the US to justify their construction as replacement for those that are being shut down, let alone to increase their contribution to clean energy. In fact we are likely to see a very significant reduction in their contribution electric energy production unless we can reduce their construction and operating costs. Many of these high costs are regulatory driven. It does appear that this effort will require the establishment of an Industry/NRC team of personnel dedicated to help make possible a realistic future for Nuclear power. The industry team should include NSSS suppliers, interested utilities and interested engineering and construction companies.
Timothy J. Jorgensen, Director of the Health Physics and Radiation Protection Graduate Program and Associate Professor of Radiation Medicine, Georgetown University - You might guess that a frequent flyer’s radiation dose is coming from the airport security checkpoints, with their whole-body scanners and baggage x-ray machines, but you’d be wrong. The radiation doses to passengers from these security procedures are trivial. The major source of radiation exposure from air travel comes from the flight itself. Most people do not fly 370,000 miles (equal to 150 flights from Los Angeles to New York) within their lifetimes. So for the average flyer, the increased risk is far less than 0.01 percent.
