William Happer, Professor of Physics - He believes that the increase of CO2 is not a cause for alarm and will be good for mankind. He predicts that future historians will look back on this period much as we now view the period just before the passage of the 18th Amendment to the US Constitution to ban the manufacturing, sale or transportation of intoxicating liquors. It as the 1917 version of saving the planet. What about the frightening consequences of increasing levels of CO2? In a word, they are wildly exaggerated, just as the purported benefits of Prohibition. At least 90% of greenhouse warming is due to water vapor and clouds. Carbon dioxide is a bit player.
William Happer, Professor of Physics, Princeton University - He is a strong supporter of a clean environment. We need to be vigilant to keep land, air and waters free of real pollution, particulates, heavy metals, pathogens, but carbon dioxide (CO2) is not one of these pollutants. Carbon is the stuff of life. Our bodies are made of carbon. Every day a normal human exhales around 1 kg of CO2 - the simplest chemically stable molecule of carbon in the earth's atmosphere.
Freeman Dyson, May, 2016 - I watched Mercury transiting the Sun. The striking fact was not the little black image of Mercury but the total absence of sunspots. I have seen many transits before this one, but never without sunspots. It seems the sun has gone to sleep as it did in the Maunder Minimum in the seventeenth century. In the seventeenth century we had the Little Ice Age and now we have the pause in global warming. Evidence getting stronger that the Sun is a big player in the climate story.
D. Kreutzer, N. Loris, K. Tubb and K. Dayaratna: Hysteria over global warming is now pervasive in the federal government, driving energy and environmental policies, and those of nearly every federal department and agency. Beyond the waste and misallocation of taxpayer dollars, these policies enable cronyism, favoring elites and undermining the fairness of our economic system. Whether one thinks global warming poses little or no threat or that the planet is on a path toward catastrophe, the cumulative climate effect of these policies, if implemented, would be a change in the earth’s temperature almost too small to measure.
Alex Epstein, Forbes: Thanks in large part to our use of hydrocarbon (fossil) fuels, which release carbon dioxide when combusted, CO2 now constitutes, by popular estimates, .01% more of the atmosphere than it did in 1850. Does that constitute a large and growing threat of rising sea levels?
President Barack Obama, John Holdren, Director of Office of Science and Technology Policy, Assistant to the President for Science and Technology - The White House said that heat wave deaths in the U.S. could worsen by 2030 due to climate change, killing over 10,000 in a single summer. John Holdren, Obama's senior science adviser, said steps the world agreed to in Paris last year to curb emissions through 2030 can help fight the risks to health. "We will need a big encore after 2030 ... in order to avoid the bulk of the worst impacts described in this report," he said.
Bjorn Lomborg - The Obama administration released a new report this week that paints a stark picture of how climate change will affect human health. Higher temperatures, we’re told, will be deadly—killing “thousands to tens of thousands�? of Americans. The report is subtitled “A Scientific Assessment,�? presumably to underscore its reliability. But the report reads as a political sledgehammer that hypes the bad and skips over the good. It also ignores inconvenient evidence—like the fact that cold kills many more people than heat.
Mario Loyola - The Danish scientist Bjørn Lomborg, a prominent critic of the top-down international conference approach to climate change, called the Paris agreement (COP21, December 2015) the “costliest in history�? if implemented. According to Lomborg, the agreement would “reduce temperatures by 2100 by just 0.05 degrees Celsius (0.09 degrees Fahrenheit)…. This is simply cynical political theater, meant to convince us that our leaders are taking serious action…a phenomenally expensive but almost empty gesture.�? NASA scientist Jim Hansen, one of the earliest proponents of the idea that global warming is manmade, slammed the deal as “half-assed and half-baked,�? a “fake,�? and a “fraud.�?
