Roy Spencer, Ph.D. Meteorology: The total amount of CO2 humans have added to the atmosphere in the last 100 years has upset the radiative energy budget of the Earth by only 1%. How the climate system responds to that small ‘poke’ is very uncertain. Here’s a list of basic climate change questions, and brief answers based upon what I know today.
Shawn Ritenour: Professor of Economics, Fellow of The Cornwall Alliance for the Stewardship of Creation: Realism Necessary - The idea that any economist can predict the quantitative effect of an action today on the economy three hundred years from now would be laughable if not taken so seriously by politicians seeking excuses for policies to which they’re already committed on other grounds.
Neil Alexander, Ph.D. radiation damage in steels, business strategist, consultant and advocate for nuclear energy: In the 1950s, civilian nuclear power was born. We had already started using the by-products from the industry for radiation therapies to treat cancer. Now, reactors operating at not much more than atmospheric pressure using molten salts as a coolant. Reactors that can consume nuclear waste or transmute other elements into fuel. So when someone says we shouldn't develop new nuclear technologies because there were some problems in the past, tell them that that is like deciding not to develop the Dreamliner because the Wright flyer was too draughty.
Neil Alexander, Ph.D. radiation damage in steels, business strategist, consultant and advocate for nuclear energy: In this world, when we finally admit the renewables experiment was a failure, we will look around and find we have few other options available to us. New nuclear if we need it will take decades to research, develop, test, license and deploy.
