climate change

Andrew Kenny, physicist and mechanical engineer: This article discusses CO2 levels and global temperatures over the last 550 million years, roughly the period of multi-celled life. CO2 has averaged about 2,000 ppm over this time but with huge fluctuations. Temperatures by contrast have been remarkably steady except for three periods of cold (when there was ice at the poles) and a period of semi cold.

Bill McKibben is a co-founder of 360.org, a global organization committed to campaigns fighting coal power plants, oil and natural gas. Middlebury College and fellow of the American Academy of Arts and Sciences: In the course of this month, a quadrillion kernels of corn need to pollinate across the grain belt, something they can’t do if temperatures remain off the charts. Just like us, our crops are adapted to the Holocene, the 11,000-year period of climatic stability we’re now leaving… in the dust. Which tell the truth, the words or photos in this article?

The title of this article asks two questions. The author does not answer either of them. He explains how molecules like CO2 and H2O can (and they do) absorb and re-emit (i.e. scatter) specific wavelengths of infrared radiation (aka IR radiation). He is not wrong about that, but much of what he says is opinion or conjecture, and he leaves out a great deal of factual information that makes the anthropogenic global warming (AGW) narrative to be completely bogus. None of what he says answers these 2 questions. He just dodges them.

Gregory Wrightstone, geologist has been investigating the Earth’s processes for more than 35 years. He is author of the newly published book Inconvenient Facts: If globalists truly thought the climate was in as dire shape, as the U.N. suggests, you'd think they would prioritize their beliefs over their own convenience. But that's not what is happening. Instead, the Left continues to fly private jets and promote the likes of Musk, Tesla, and SpaceX — regardless of the supposed environmental harm they are facilitating. Undoubtedly, these globalists are massive hypocrites, and it's about time for America to confront them on that fact.

John Robson, historian: This website offers a forum for more open debate on all aspects of climate change, especially better use of scientific information in public discussion and policy formation. The videos are very informative.

Investor's Business Daily: The predictions by hundreds of alarmists that catastrophic man-made global warming is going to destroy the world, aren't going to happen.

Tom Wysmuller, forecasted weather at Amsterdam's Royal Dutch Weather Bureau after studying meteorology at NYU and Stanford. Worked throughout NASA and its Directorates before, during and after the Moon Landings. In 2016, he was the featured Sea-Level speaker at the World Congress of Oceans in Qingdao, China. Lecturer at Colderside.com. His research shows that man-made carbon dioxide is not anywhere close to being the leading cause of climate change. There is no such thing as man-made global warming or man-made climate change. It is a ruse to control the world's use of fossil fuels. Strictly a political action to control economies and establish who rules the world.

Nuclear energy is the cleanest, safest, densest, and most reliable energy source. The value proposition for nuclear energy is unparalleled. It is the answer for governments and nongovernmental organizations worldwide that are clamoring for a reduction in human-generated CO2 emissions. Humans flourish when they have access to plentiful, safe, and reliable energy. Nuclear excels at all of these.

One of the easiest things to do is to go along to get along. This is true in so many areas of life, including knowledge of science topics. If you don’t have an in-depth knowledge of a particular area of science, the “easiest thing” kicks in rather effortlessly.

Apparently, the fate of civilization depends on adherence to alarmists with insight of the future of Earth’s atmosphere that is overly burdened by the emissions of modern living.

Certainly, human activity has an impact on the environment, but not all of it is bad. And most of the bad can be mitigated with reasonable action — action that can be informed by disparate perspectives.

Ed Berry, physicist and climate scientist: These 8 words are the death of climate change: It violates the Equivalence Principle, therefore it’s wrong. IPCC’s Big Idea (its fundamental hypothesis) is that nature treats human CO2 emissions differently than it treats nature’s CO2 emissions. Einstein used the Equivalence Principle to develop his General Theory of Relativity. He realized that data cannot tell the difference between gravity and inertial forces. Therefore, they are the same thing. This equivalence is the foundation of Einstein’s General Theory of Relativity that we use today.

Howard Cork Hayden is an emeritus professor of physics from the University of Connecticut. The Energy Advocate, TEA, is his monthly publication about many topics related to energy. This article has excerpts from the September, 2016 edition about nuclear energy and the star gymnast in the 2016 Olympics. Each issue is packed with interesting essays for students, teachers, parents, and the public. To order TEA, see instructions in this article.

John Robson: For the past 2.5 million years the Earth has been unusually cold, with repeated glaciations whose periodic advances and retreats science cannot model or predict. In fact we are still in an “ice age” today, with significant polar ice, though in a relatively warmer “interglacial”. Fortunately. Civilization would be impossible without the warming that started suddenly 12,000 years ago, and would become very difficult if the glaciers began another sudden advance. If the Earth actually is now warming, relative to 15,000 years ago or indeed the “Little Ice Age” from the end of the Middle Ages into the mid-19th century, it would be neither surprising nor man-made.

April 30, 2021, is Arbor Day; a day when we are encouraged to "plant a tree". It would be appropriate to adopt a second slogan, "feed a tree". Feeding-a-tree can be accomplished by implementing a greenhouse operating procedure that uses our carbon emissions ("carbon dioxide", "CO2") to enrich the atmosphere.

American President Joe Biden and his Climate Crisis Czar John Kerry are leading a campaign to starve-trees (and humanity). It is based on the mistaken belief that CO2 provides us with a global, temperature-control knob. Astonishingly, the alarmists' own climate models overwhelmingly debunk the "climate-emergency" fear mongering.

Howard Brady, Geologist. Author of Mirrors & Mazes, A guide through the climate debate: There is now a New Inquisition presided over by a clique of scientists who have given themselves the right of trial to put scientific heretics to the stake. The new torture methods are not the stake or the rack but the denial of promotion, the manipulation of the media to denigrate, and the refusal to employ. Indeed, efforts to stop such scientists publishing in scientific periodicals have extended to controlling the editorial committees of many well-known periodicals. This is the modern equivalent of the Spanish Inquisition’s Burning of the Books. (Brady, 2017)

William Gray Ph.D. is emeritus professor of Atmospheric Science at Colorado State University (CSU). He is noted for his forecasts of Atlantic hurricane season activity. His last general comment about the 2013 IPCC Climate Change Report: "You have failed once more to show that the climate is influenced in any way by changes in emissions of trace gases. I have already shown that your model is defective. You have never subjected it to the necessary discipline of validation which requires successful prediction of a range of future climate properties."

Sarah Kaplan, The Washington Post: About 700 million years ago, Earth turned into a snowball. The polar ice sheets expanded until they engulfed the globe. The oceans turned to slush. The vast expanses of ice and snow reflected the sun's light back into space, exacerbating the endless winter. Temporary relief came in the form of massive volcanic eruptions, which spewed carbon dioxide into the atmosphere and triggered a period of global warming. But that, too, spiraled out of control. Earth became a greenhouse — its oceans hot enough to cook their inhabitants, its blighted landscape further ravaged by floods. Then, suddenly, something about the shifting continents or ash-darkened skies prompted the planet to cool again. The snowball returned.

Fritz Vahrenholt, PhD Chemistry, Chairman, German Wildlife Foundations: The foundation of the Paris Climate Change Agreement has collapsed. By 2100, whatever we do, we will not exceed the 2 degree limit. What happens to the worldwide use of coal? There is no departure from coal except in Europe and Canada. China and India, according to the Paris Agreement, like all developing countries, massively expand coal-fired power stations. In China, 280,000 MW will be added, in India 174,000 MW. By comparison, the entire brown coal fleet in Germany has a capacity of 22,700 MW. 1600 coal-fired power plants are built in 62 countries worldwide, most of them by Chinese power plant builders and with the help of Chinese loans
