The Conundrums of Scientific Consensus

Here’s a question for the logicians out there: How do you reconcile this :

Climate change is happening faster than previously predicted according to a new World Wildlife Fund report.

Bringing together some of the most recent scientific reports and data, “Climate change: faster, stronger, sooner” reveals that global warming is accelerating more rapidly than the predictions made in the IPCC’s Fourth Assessment Report published in 2007.

One of the most concerning aspects of recent data is evidence that, in some places, the Arctic Ocean is losing sea ice 30 years ahead of current IPCC predictions.

Summer sea ice is now forecasted to completely disappear in the summer months sometime between 2013 and 2040—something which hasn’t happened for over a million years.

With this :

The number of climate change skeptics is growing rapidly. Because a funny thing is happening to global temperatures—they’re going down, not up.

On the same day (Sept. 5) that areas of southern Brazil were recording one of their latest winter snowfalls ever and entering what turned out to be their coldest September in a century, Brazilian meteorologist Eugenio Hackbart explained that extreme cold or snowfall events in his country have always been tied to “a negative PDO” or Pacific Decadal Oscillation. Positive PDOs—El Ninos—produce above-average temperatures in South America while negative ones—La Ninas—produce below average ones.

Dr. Hackbart also pointed out that periods of solar inactivity known as “solar minimums” magnify cold spells on his continent. So, given that August was the first month since 1913 in which no sunspot activity was recorded—none—and during which solar winds were at a 50-year low, he was not surprised that Brazilians were suffering (for them) a brutal cold snap. “This is no coincidence,” he said as he scoffed at the notion that manmade carbon emissions had more impact than the sun and oceans on global climate . . . .

Don Easterbrook, a geologist at Western Washington University, says, “It’s practically a slam dunk that we are in for about 30 years of global cooling,” as the sun enters a particularly inactive phase. His examination of warming and cooling trends over the past four centuries shows an “almost exact correlation” between climate fluctuations and solar energy received on Earth, while showing almost “no correlation at all with CO2.”

An analytical chemist who works in spectroscopy and atmospheric sensing, Michael J. Myers of Hilton Head, S. C., declared, “Man-made global warming is junk science,” explaining that worldwide manmade CO2 emission each year “equals about 0.0168% of the atmosphere’s CO2 concentration . . . . This results in a 0.00064% increase in the absorption of the sun’s radiation. This is an insignificantly small number.” . . .

For nearly 30 years, Professor Christy has been in charge of NASA’s eight weather satellites that take more than 300,000 temperature readings daily around the globe. In a paper co-written with Dr. Douglass, he concludes that while manmade emissions may be having a slight impact, “variations in global temperatures since 1978 . . . cannot be attributed to carbon dioxide.”

Moreover, while the chart below was not produced by Douglass and Christy, it was produced using their data and it clearly shows that in the past four years—the period corresponding to reduced solar activity—all of the rise in global temperatures since 1979 has disappeared.
