Euan Mearns, geologist: He takes a close look at the data on temperatures, carbon dioxide (CO2), and methane (CH4) found in the Vostok Ice Core of Antarctica. He focuses on the Eemian warm period between 130,000 and 115,000 years ago. This warm period was the last warm period before the current warm period, the Holocene. In her 2008 graphs showing the relationship between CO2 and temperatures from the Vostok Ice Core covering the entire record, Jo Nova stated the average lag was about 800 years, with temperatures rising (falling) about 800 years before CO2 rising (falling). This lag indicates that CO2 could not be the cause of rise or fall of temperatures.

Michael Shellenberger is a Time Magazine "Hero of the Environment" and Green Book Award-winning author and policy expert. For a quarter-century he has advocated solutions to lift all people out of poverty while protecting the natural environment. Alvin Weinberg was a math and chemistry prodigy. He entered the University of Chicago the following year, and over the next two decades worked alongside all the greats, including Enrico Fermi, Leo Szilard and Eugene Wigner. By the time he was 40, Weinberg had co-invented the pressurized water reactor, the boiling water reactor, the sodium fast reactor, the homogeneous reactor, the molten salt reactor, the atomic bomb — and the American Nuclear Society.

This is The American Nuclear Society's report on Nine Grand Challenges by 2030. Hopefully, they will make a lot of progress. The progress so far has been insufficient to maintain a healthy nuclear industry.

The American Nuclear Society has announced that it will focus on Nine Grand Challenges by 2030. It is time that they commit to greater focus on these broad challenges and resolve them. Major expansion of nuclear power desperately needs them resolved.
