CBS News: "Researchers say increasingly large amounts of CO2 are accumulating in the atmosphere. They fear the earth will gradually become warmer causing as yet uncertain but possibly disruptive changes in the Earth's climate 50 to 70 years from now." ...
Sen. Paul Tsongas (D-Mass) Senate Energy Committee: "It's possible probable we really don't know. But if it happens it means goodbye Miami, goodbye Corpus Christi, goodbye Sacramento, goodbye Boston -- which obviously is much more of a concern. Goodbye New Orleans. Goodbye Charleston, Savannah, and Norfolk. On the positive side, it means that we could enjoy boating at the foot of the Capitol and fishing on the South Lawn."
Gordon MacDonald, Mitre Corp Chief Scientist: "One model of climate the Jason climate model predicts that doubling carbon dioxide will result in August and Washington DC that are 9 degrees centigrade warmer or 16 degrees Fahrenheit than current summers but that the winters will only be 2 degrees centigrade warmer changes of this. Changes of this magnitude are very probably going to have a profound effect on agriculture, on all of the aspects of energy use and generation, and on water and land use."
Climate Depot's Morano: “Climate fear promoters switched effortlessly from global cooling fears in the 1970s to global warming fears in the 1980s. In the present day, the phrase 'global warming' has lost favor in favor of 'climate change' or 'global climate disruption' or even 'global weirding,’
Dr. Happer: "The rationale for the crusade against co2, it's almost a religious thing people believe in." .. What are the facts? Is climate change a problem? The answer is NO, it's not a problem at all and co2 is not a problem at all."
Paleoclimate data indicate there was less Arctic sea ice during the pre-industrial period than in modern times, or when CO2 concentrations were 100 ppm lower than today (280 vs. 380 ppm).
Scientists (Diamond et al., 2021) assert that during the 18th and 19th centuries Arctic sea ice extent minimum (September) values averaged 5.54 million km². Though modern sea ice losses are often characterized as dangerously low, satellite data indicate the 2002-’06 five-year average minimum sea ice extent was 5.92 million km², which is 0.38 km² above the 1700s and 1800s or pre-industrial (PI) levels. ...
Several other studies also affirm the sea ice losses observed via satellite in recent decades are not unusual or unprecedented when compared to past centuries.
“Economies worldwide nearly ground to a halt over the 15 months of the coronavirus pandemic, leading to a startling drop in global greenhouse gas emissions,” the Washington Post’s story last June 7 said. “But the idle airplanes, boarded-up stores and quiet highways barely made a dent in the steady accumulation of carbon dioxide in the atmosphere, which scientists from the Scripps Institution of Oceanography and the National Oceanic and Atmospheric Administration (NOAA) said Monday had reached the highest levels since accurate measurements began 63 years ago,” the Washington Post story said. Similarly, the New York Times reported last June 4, “Despite the economic collapse resulting from the coronavirus pandemic, which has led to sharp declines in carbon dioxide emissions, the amount of the greenhouse gas has continued to climb.” ...
“Scientific instruments atop the Mauna Loa volcano in Hawaii showed that levels of carbon dioxide in the air averaged 419 parts per million in May, the annual peak, according to two separate analyses from the Scripps Institution of Oceanography and the National Oceanic and Atmospheric Administration,” the New York Times story said. “Those readings are about half a percent higher than the previous high of 417 parts per million, set in May 2020.”
Today’s levels of roughly four hundred parts per million (PPM) of CO2 are not alarming. In geologic terms, today’s CO2 levels are among the lowest in earth’s history.
“Climate change is governed by hundreds of factors or variables, and the very idea that we can manage climate change predictably by understanding and manipulating at the margins one politically selected factor (CO2), is as misguided as it gets. It’s scientific nonsense,” University of London professor emeritus Philip Stott has noted.
Atmospheric scientist Hendrik Tennekes, a pioneer in the development of numerical weather prediction and former director of research at the Netherlands’ Royal National Meteorological Institute, declared: “I protest vigorously the idea that the climate reacts like a home heating system to a changed setting of the thermostat: just turn the dial, and the desired temperature will soon be reached.”
Lindzen: "Despite the fact that increases of CO₂ thus far have been accompanied by the greatest increase in human welfare in history, and despite the fact that there have been large increases in the Earth’s vegetated area largely due to increases in CO₂’s role in photosynthesis, governments seem to have concluded that another 0.5 C will spell doom."
"China's emissions that presumably have led to the observed increase in CO₂ have continued to increase. Increasing emissions from China, India, and the rest of the developing world swamp the small reductions in the Anglosphere and the European Union. Indeed, if emissions from the Anglosphere and the EU were to cease (which is of course an impossibility), it would make little difference. According to the Global Energy Monitor, China is planning the addition of 200 GW of coal-fired generating capacity by 2025. If we assume this is a four-year period and that a large-scale power plant is 1 GW, that would be about one plant per week over the next four years...they also recognize that climate hysteria in the West leads to policies that clearly benefit China. Indeed, China is actually promoting activities like the Sino-American Youth Dialogue on climate change to promote climate alarm among young American activists."
