Dr. Allan begins - 0:09: The current round of fear of human-caused global warming really started in the 1970s. Based on the best available surface data, from 1940 to the mid-1970s global temperatures had been falling, creating fears of another ice age.
( https://history.aip.org/climate/timeline.htm ). There was no serious concern of an ice age in the 70s, quite the contrary.
0:09 The current round of fear of human-caused global warming really started in the 1970s.
Rather than facts and logical arguments the Right Wing used faith-based absolutism, innuendo, lies and malicious slander - then called it their free speech, thus creating the kangaroo debates that have destroyed constructive learning and dialogue about this all important topic.
0:23 Around 1977, temperatures suddenly rose. At that time, the reasons for this sudden increase were not known. Some scientists suggested the cause of the sudden warming was an increase in carbon dioxide, and other greenhouse gases, that came with the Industrial Revolution.
Once global Clean Air Acts started cleaned up the atmosphere of aerosols (that were killing city dwellers and tough on other animals and plant), that reflectivity was eliminated so more of the sun’s energy reached Earth. As reflected in higher temperatures.
0:41 The Climate Research Board appointed an Ad Hoc Study Group to examine the impact of greenhouse gases on the earth’s temperatures. The study group was headed by the noted American meteorologist Jule G. Charney.
Their report published in 1979 was called the Charney Report. It estimated that “the most probable global warming for a doubling of carbon dioxide to be near 3ºC with a probable error of ±1.5ºC.” According to the Charney Report, there are two components to human-caused greenhouse gas warming.
1:10 The first component is directly from increased carbon dioxide and is estimated from laboratory experiments to be modest. The second component of human-caused global warming is an indirect, a positive feedback, from increased atmospheric water vapor, and would be far more powerful than the direct warming from carbon dioxide. Since, in 1979, there were no comprehensive measurements of atmospheric temperatures, the estimates in the Charney Report could not be confirmed or disproven.
1:40 But, since it proposed the warming starts in the atmosphere, atmospheric warming trends would have to be more pronounced than surface warming trends because much of the energy from atmospheric warming is lost into space.
1:56 Unfortunately, there was pressure to take action before we understood the problem.
1:56 Before a method to measure atmospheric temperatures was developed which could be used to directly test the greenhouse gas warming hypothesis, international organizations were being mobilized to control greenhouse gases that were estimated, guessed, to cause global warming. The international solution was to control carbon dioxide emissions. The conflict among scientists as to adequate testing of the hypothesis became very public with the involvement of governmental organizations, and the money started to flow.
This does leave out the Feedback question - see end of this expose'.
2:30 Thus the resulting conflict is largely political, not scientific, and financed by governments seeking to control carbon dioxide emissions for political reasons.
Allan: The U.S. government is heavily involved in financing the position that global warming is dangerous and is caused by industry, transportation, and the generation of electricity by carbon-based fuels.
Why has the GOP so wrapped themselves within such profoundly disconnected rejection of down to Earth realities, while the evidence keeps piling up faster than we can process it? It’s a horrifying thing to behold.
Allan: At the same time, independent research efforts are producing evidence that call into question the fear of man-made global warming. Two American scientists,
What he calls "independent" are high dollar advocacy firms, there's a great deal that's been documented about these Right Wing organizations and their 'think tanks' and the resulting campaigns dedicated to public stupefaction.
3:06 Roy Spencer and John Christy, developed a method to finally measure global atmospheric temperatures, `. For developing the method to calculate atmospheric temperatures, Spencer and Christy have been awarded NASA’s Medal for Exceptional Scientific Achievement.
3:18 But the data they’ve collected don’t confirm the predicted result. Independent researchers have tested the hypothesis against atmospheric temperature data, now extending over thirty-seven years. The assumptions in the Charney Report are not supported by nature.
3:34 The failure to find physical evidence supporting the assumptions about global warming is not due to a lack of public funding.
Charney et al, 1979
Because of the political, not scientific, impact of global warming, the United States alone has spent billions of taxpayer dollars on global warming issues.
3:50 You can find all the details of our calculations on our website, linked in the description, but from Fiscal Year (FY) 1993 to FY 2014 total US expenditures on climate change amounted to more than $166 Billion in 2012 dollars.
4:06 By way of comparison, the Congressional Budget Office estimated that the entire Apollo program, from 1962 to 1973 with 17 missions, and 7 of them sending men to the moon and returning them cost $200 Billion in 2012 dollars. In other words, we’ve spent almost as much on global warming as we spent on the Apollo program.
4:26 And that’s just direct government spending (including tax subsidies). It doesn’t count the many billions that represent the cost of government regulations or the jobs that are lost. It’s time to finally recognize the shaky science Global Warming stands on, and stop spending spending massive amounts of taxpayer dollars on a highly questionable hypothesis.
