Tom Harris, executive director of the Ottawa, Canada-based International Climate Science Coalition: In a recent interview with the Vatican News service, former U.S. Vice President Al Gore again claimed “the climate crisis is now the biggest existential challenge humanity has ever faced.” The Goddard Institute for Space Studies asserts that the Global Annual Mean Surface Air Temperature Change from 1880 to 2017 is only just over one degree Celsius despite a reputed 40% rise in atmospheric carbon dioxide (CO2) content.
Ed Berry, PhD in Physics with a focus on atmospheric physics. Dr. Berry’s theoretical PhD thesis is recognized as a breakthrough in the science of rain formation and in the use of computer-based numerical models: IPCC claims human emissions have caused ALL the increase in CO2 since 1750. They say it was 280 ppm in 1750 and human emissions alone caused it to rise to 410 ppm today. My preprint shows natural CO2 causes 392 ppm of today’s CO2 level and human CO2 causes only 18 ppm, for today’s total of 410 ppm.
Brian Wullivn, Eric Roston, Bloomberg: Kinked, buckled, stuck or stalled, it doesn’t matter how you describe it, the jet stream -- the ribbon of wind that circles the Earth -- is doing strange things. The calamity list includes wildfires across Scandinavia, Greece and California, record heat in Texas, Japan and Africa and flooding rains along the U.S. East Coast that could last another week. The world is hotter in general, which means when temperatures spike, they do so off a higher baseline. Is all of this due to mankind's use of fossil fuels?
Viv Forbes, Executive Director of The Salt Bush Club, Australia: The key role of Carbon in the cycle of life is as a source of food and energy and in the atmosphere.
Terry Donze, geophysicist: The Arctic sea ice on June 26, 2018 covered most of the Acrtic Ocean, like most years since 2000. See photos of nature flourishing in the Arctic.
Thorpe Watson, metallurgical engineering and materials science: The human-induced, global-warming narrative has tremendous traction despite nature’s refusal to co-operate. The narrative falsely claims that carbon dioxide (“CO2” – aka “carbon emissions”) is a pollutant and that it provides mankind with the ability to control the planet’s climate. In reality, CO2 is not a climate-control variable but it is a colourless, odourless, trace gas that is as important as oxygen and water in sustaining life on the planet. The subterfuge implies that hydrocarbon fuels (aka “fossil fuels” – coal, oil, and natural gas) do not provide clean energy, allegedly because of their so-called “carbon emissions”.
Paul Driessen, senior policy analyst for the Committee For A Constructive Tomorrow, Pope Francis: We must “enter into dialogue with all people about our common home,” Pope Francis recently told the US Congress, frequently quoting from his Laudato Si encyclical. “We need a conversation which includes everyone, since the environmental challenge … and its human roots concern and affect us all.” I couldn’t agree more. Unfortunately, the pontiff seems more interested in a lecture than a conversation on climate change. The pope’s advisors believe humans are destroying our planet and dangerously changing its climate. This website shows over a thousand photos of how beautiful the world is today with snow falling from the Equator to the Poles. How much more snow do climate alarmists need in order that they will permit the world to continue using fossil fuels?
William Happer, Emeritus Professor of Physics, Steven Koonin, New York University, Center for Urban Science and Progress, Under Secretary for Science at U.S. Depart. of Energy in President Obama's administration, Richard Lindzen Emeritus Professor, MIT Department of Earth, Atmospheric, and Planetary Sciences: This is a tutorial on man-made global warming, man-made climate change for the U.S. District Court, Northern District of California, San Francisco Division. 1) The climate is always changing. 2) Human influences on the climate are a small (1%) perturbation to natural energy flows. 3) It is not possible to tell how much of the modest recent warming can be ascribed to human influences. 4) There have been no detrimental changes observed in the most salient climate variables and today's projections of future changes are highly uncertain.
Don Bogard, radio-geochemistry, nuclear geochemistry, planetary science: Carbon (C) exchange rates among C reservoirs tend to be at equilibrium unless and until a significant environmental change disturbs that. A significant increase in atmospheric (Atmos) CO2 concentration over the past century has been such a disturbance, and as a consequence a large fraction of that growth in Atmos CO2 has manifested as new plant growth and to increased ocean C levels. Increased temperature over the past century (which mostly has only modestly affected the ocean) and any tendency for warmer surface ocean to degas more CO2, has been over-powered by higher Atmos CO2 shifting the chemical equilibrium toward more dissolution of Atmos CO2 into the oceans. Higher decay rates of soil biotic material caused by the increased temperatures may be a source of part of the Atmos CO2 increase over the past century. However, it is most unlikely that organic decay has been other than a minor source, especially in the past few decades when Atmos CO2 was growing most rapidly.
Bonne Posma, physicist, Andrew Kenny, physicist, mechanical engineer: It is interesting to note that previous CO2 alarmist, James Lovelock (originator of the Gaia hypothesis), reversed himself about 10 years ago and now supports increased use of fossil fuels to potentially help mitigate the effects of the next ice age. This action was also proposed in 1900 by the first proponent of CO2-linked global warming, Svante Arrhenius (Nobel Prize in Chemistry 1903).
