Meteorologists, Scientists Explain Why There Is 'No Climate Emergency'

 

 He said one example is a recent research paper that estimated that changes in the sun’s output could explain 70 to 80 percent of global warming. Research such as that doesn’t gain much traction because the IPCC is committed to the idea that human CO2 is the cause of global warming.

As further criticism, Mr. Alexander said John Christy, a climatologist and professor of atmospheric science at the University of Alabama in Huntsville and the director of the Earth System Science Center, has clearly demonstrated that climate models exaggerate short-term future warming by two to three times.

To find more accurate measurements, Mr. Christy and Roy Spencer, a climatologist, former NASA scientist, and now a principal research scientist at the University of Alabama in Huntsville, developed a global temperature data set from microwave satellite observations.

They started their project in 1989, analyzed data going back to 1979, and found that, in general, since 1979, the Earth’s temperature has increased steadily by 0.23 degrees Fahrenheit every 10 years, according to global satellite data, Mr. Spencer said on his website.

As for why climate models are so inaccurate, Mr. Alexander said: “Computer simulations are only as reliable as the assumptions that the computer model is built on, and there are many assumptions that go into climate models. Assumptions about processes we don’t fully understand require approximations.
