A former high-ranking Obama administration official says climate science and the implications of global warming are not "settled," insisting such claims are "misguided" and stifle debate on the matter.

Writing a Page One story in the Wall Street Journal Weekend Review section, Dr. Steven Koonin argues that group think among experts has been inhibiting "the scientific and policy discussions that we need to have about our climate future."

Koonin, who served at the Energy Department as President Obama’s undersecretary for science in the Energy Department, is director of the Center for Urban Science and Progress at New York University.

Koonin’s position strikes a blow against climate change activists as People’s Climate March organized demonstrations at more than 2,000 locations worldwide.

In New York, tens of thousands participated in the demonstration demanding urgent steps against carbon emissions as the United Nation’s General Assembly opened.

"We often hear that there is a 'scientific consensus' about climate change," writes Koonan. "But as far as the computer models go, there isn't a useful consensus at the level of detail relevant to assessing human influences."

Koonin says his extensive training as a computational physicist with a 40-year career of scientific research and management, has given him an up-close knowledge of climate science.

"Detailed technical discussions during the past year with leading climate scientists have given me an even better sense of what we know, and don't know, about climate," writes Koonin.

The point, Koonin says, isn't whether the climate is changing, as "the climate has always changed and always will."

I remember the good old days, when 90+ year olds in nursing homes lived forever. Darn this pesky virus.

Models that show Arctic ice melting over the past 20 years forget to note the almost equal growth of ice across Antarctica, which he says is “now at a record high.”

A prediction that the “lower atmosphere in the tropics will absorb much of the heat of the warming atmosphere” has not materialized.

The fact global sea levels in the first half of the 20th century rose at almost the same rate as today.

Climate sensitivity— "that is, the warming induced by a hypothetical doubling of carbon-dioxide concentration," he says is "no different, and no more certain" than it was 30 years ago.

I heard about this new NASA study and thought this thread the best one of the more recent climate change threads to make the
post.

Study Finds Earth’s Ocean Abyss Has Not Warmed

Oct. 6, 2014: The cold waters of Earth’s deep ocean have not warmed measurably since 2005, according to a new NASA study, leaving unsolved the mystery of why global warming appears to have slowed in recent years.

Scientists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, analyzed satellite and direct ocean temperature data from 2005 to 2013 and found the ocean abyss below 1.24 miles (1,995 meters) has not warmed measurably. Study coauthor Josh Willis of JPL said these findings do not throw suspicion on climate change itself.

"The sea level is still rising," Willis noted. "We're just trying to understand the nitty-gritty details."

Deep sea creatures, like these anemones at a hydrothermal vent, are not yet feeling the heat from global climate change. Although the top half of the ocean continues to warm, the bottom half has not increased measurably in temperature in the last decade. Image credit: NERC

In the 21st century, greenhouse gases have continued to accumulate in the atmosphere, just as they did in the 20th century, but global average surface air temperatures have stopped rising in tandem with the gases. The temperature of the top half of the world's oceans -- above the 1.24-mile mark -- is still climbing, but not fast enough to account for the stalled air temperatures.

Many processes on land, air and sea have been invoked to explain what is happening to the "missing" heat. One of the most prominent ideas is that the bottom half of the ocean is taking up the slack, but supporting evidence is slim. This latest study is the first to test the idea using satellite observations, as well as direct temperature measurements of the upper ocean. Scientists have been taking the temperature of the top half of the ocean directly since 2005, using a network of 3,000 floating temperature probes called the Argo array.
