Has there actually been a scientific debate over global warming?

This is a history question, which is up my alley. To this question the answer is yes and no.

On Aug. 22, 1981 The New York Times published a front-page story by Walter Sullivan titled
STUDY FINDS WARMING TREND THAT COULD RAISE SEA LEVELS

about NASA'a James Edward Hansen and his forthcoming global warming paper in Science, conceding that the past century's warming lays within the range of historical averages but predicting the emergence of an anthropogenic global warming signal, with the soundbytes:

"A team of Federal scientists says it has detected an overall warming trend in the earth's atmosphere extending back to the year 1880. They regard this as evidence of the validity of the 'greenhouse' effect, in which increasing amounts of carbon dioxide cause steady temperature increases. "The seven atmospheric scientists predict a global warming of 'almost unprecedented magnitude' in the next century. It might even be sufficient to melt and dislodge the ice cover of West Antarctica, they say, eventually leading to a worldwide rise of 15 to 20 feet in the sea level. In that case, they say, it would 'flood 25 percent of Louisiana and Florida, 10 percent of New Jersey and many other lowlands throughout the world' within a century or less."

"Carbon dioxide in the atmosphere, which is primarily a result of mankind's burning of fuels, is thought to act like the glass of a greenhouse. It absorbs heat radiation from the earth and its
atmosphere, heat that otherwise would dissipate into space. Other factors being equal, the more carbon dioxide there is in the atmosphere, the warmer the earth should become, according to the theory";

"Dr. Hansen and his colleagues cite the observed surface temperatures of Mars and, particularly, Venus as support for their predicted greenhouse effect. The surface of Venus, with an atmosphere formed largely of carbon dioxide, is at about 900 degrees Fahrenheit";

"The possibility that the greenhouse effect could alter the earth's temperature has long been debated. Scientists have agreed that carbon dioxide is increasing, but disagree on whether temperatures are also increasing. The major difficulty in accepting the greenhouse theory 'has been the absence of observed warming coincident with the historic carbon dioxide increase,' the scientists wrote.

“Researchers were further confounded by an apparent cooling trend since 1940. As a result, many atmospheric scientists concluded that the climatic effects of increased carbon dioxide might not become detectable for many decades. But the Government scientists say they see clear evidence that carbon dioxide added to the atmosphere since the Industrial Revolution has already warmed the climate";

"Their conclusion that the climate has warmed by almost one degree in the last century is based on a re-analysis of global observations, paying special attention to the Southern Hemisphere.

'The common misconception that the world is cooling,' they say, 'is based on Northern Hemisphere experience to 1970.'"

Notice where it says Federal Government scientists. James Hansen was their leader, coopting NASA to his views to this day. From day one they’ve had an agenda to push CO2-driven global warming with not even the slightest hint of fairness and objectivity. So much for debate. And there is a new kid on the block. For decades now the evil insidious globalist Marxist U.N. IPCC has compromised scientists, academics, and journalists to push their agenda and shut down all debate, so if there ever will be a real honest fair one it will be possible only after they’re gone, sorry. Only Pres. Trump is attempting to organize a fair panel to investigate, which predictably is drawing howls from the IPCC octopus, who don’t want any debate to mess up their plans to bilk trillions in order to end capitalism and set up a Marxist utopia.
