Why Kerry Is Flat Wrong on Climate Change

It was the scientific skeptics who bucked the 'consensus' and said the Earth was round.

"The rate of warming forecast by these models depends on many assumptions and engineering to replicate a complex world in tractable terms, such as how water vapor and clouds will react to the direct heat added by carbon dioxide or the rate of heat uptake, or absorption, by the oceans.

We might forgive these modelers if their forecasts had not been so consistently and spectacularly wrong. From the beginning of climate modeling in the 1980s, these forecasts have, on average, always overstated the degree to which the Earth is warming compared with what we see in the real climate.

For instance, in 1994 we published an article in the journal Nature showing that the actual global temperature trend was "one-quarter of the magnitude of climate model results." As the nearby graph shows, the disparity between the predicted temperature increases and real-world evidence has only grown in the past 20 years."

"The models mostly miss warming in the deep atmosphere—from the Earth's surface to 75,000 feet—which is supposed to be one of the real signals of warming caused by carbon dioxide. Here, the consensus ignores the reality of temperature observations of the deep atmosphere collected by satellites and balloons, which have continually shown less than half of the warming shown in the average model forecasts.

The climate-change-consensus community points to such indirect evidence of warming as glaciers melting, coral being bleached, more droughts and stronger storms. Yet observations show that the warming of the deep atmosphere (the fundamental sign of carbon-dioxide-caused climate change, which is supposedly behind these natural phenomena) is not occurring at an alarming rate: Instruments aboard NASA and National Oceanic and Atmospheric Association satellites put the Mid-Tropospheric warming rate since late 1978 at about 0.7 degrees Celsius, or 1.3 degrees Fahrenheit, per 100 years. For the same period, the models on average give 2.1 degrees Celsius, or 3.8 degrees Fahrenheit, per 100 years (see graph).

The models also fail to get details of the past climate right. For example, most of the observed warming over land in the past century occurred at night. The same models used to predict future warming models showed day and night warming over the last century at nearly the same rates.

Past models also missed the dramatic recent warming found in observations in the Arctic. With this information as hindsight, the latest, adjusted set of climate models did manage to show more warming in the Arctic. But the tweaking resulted in too-warm predictions—disproved by real-world evidence—for the rest of the planet compared with earlier models."
