The warm-mongers are wrong 7

Lee Gerhard is a geologist and a reviewer for the Intergovernmental Panel on Climate Change (IPCC). Here’s what he has to say about greenhouse gases, CO2 concentrations and effect, Arctic and Antarctic ice, polar bears, human influence on global temperature and so on (from Icecap):

It is crucial that scientists are factually accurate when they do speak out, that they ignore media hype and maintain a clinical detachment from social or other agendas. There are facts and data that are ignored in the maelstrom of social and economic agendas swirling about Copenhagen. Greenhouse gases and their effects are well-known. Here are some of things we know:

• The most effective greenhouse gas is water vapor, comprising approximately 95 percent of the total greenhouse effect.

• Carbon dioxide concentration has been continually rising for nearly 100 years. It continues to rise, but carbon dioxide concentrations at present are near the lowest in geologic history.

Temperature change correlation with carbon dioxide levels is not statistically significant.

There are no data that definitively relate carbon dioxide levels to temperature changes.

• The greenhouse effect of carbon dioxide logarithmically declines with increasing concentration. At present levels, any additional carbon dioxide can have very little effect.

We also know a lot about Earth temperature changes:

Global temperature changes naturally all of the time, in both directions and at many scales of intensity.

• The warmest year in the U.S. in the last century was 1934, not 1998. The U.S. has the best and most extensive temperature records in the world.

• Global temperature peaked in 1998 on the current 60-80 year cycle, and has been episodically declining ever since. This cooling absolutely falsifies claims that human carbon dioxide emissions are a controlling factor in Earth temperature.

Voluminous historic records demonstrate the Medieval Climate Optimum (MCO) was real and that the “hockey stick” graphic that attempted to deny that fact was at best bad science. The MCO was considerably warmer than the end of the 20th century.

• During the last 100 years, temperature has both risen and fallen, including the present cooling. All the changes in temperature of the last 100 years are in normal historic ranges, both in absolute value and, most importantly, rate of change.

Contrary to many public statements:

• Effects of temperature change are absolutely independent of the cause of the temperature change.

Global hurricane, cyclonic and major storm activity is near 30-year lows. Any increase in cost of damages by storms is a product of increasing population density in vulnerable areas such as along the shores and property value inflation, not due to any increase in frequency or severity of storms.

Polar bears have survived and thrived over periods of extreme cold and extreme warmth over hundreds of thousands of years extremes far in excess of modern temperature changes.

The 2009 minimum Arctic ice extent was significantly larger than the previous two years. The 2009 Antarctic maximum ice extent was significantly above the 30-year average. There are only 30 years of records.

• Rate and magnitude of sea level changes observed during the last 100 years are within normal historical ranges. Current sea level rise is tiny and, at most, justifies a prediction of perhaps ten centimeters rise in this century.

The present climate debate is a classic conflict between data and computer programs. The computer programs are the source of concern over climate change and global warming, not the data. Data are measurements. Computer programs are artificial constructs.

Public announcements use a great deal of hyperbole and inflammatory language. For instance, the word “ever” is misused by media and in public pronouncements alike. It does not mean “in the last 20 years,” or “the last 70 years.” “Ever” means the last 4.5 billion years.

For example, some argue that the Arctic is melting, with the warmest-ever temperatures. One should ask, “How long is ever?” The answer is since 1979. And then ask, “Is it still warming?” The answer is unequivocally “No.” Earth temperatures are cooling. Similarly, the word “unprecedented” cannot be legitimately used to describe any climate change in the last 8,000 years.

I have been a reviewer of the last two IPCC reports, one of the several thousand scientists who purportedly are supporters of the IPCC view that humans control global temperature. Nothing could be further from the truth. Many of us try to bring better and more current science to the IPCC, but we usually fail. Recently we found out why. The whistleblower release of e-mails and files from the Climate Research Unit at East Anglia University has demonstrated scientific malfeasance and a sickening violation of scientific ethics.

Exposing Al Gore’s cosmic scam 0

 From Power Line

 Earlier this month, the Heartland Institute sponsored the 2009 International Conference on Climate Change in New York. The Conference differed from most such events in that it was devoted to science, not politics or propaganda. Heartland has now made the materials presented at the conference available online, here. You can review the agenda, watch videos of the keynote presentations, read transcripts of some of the speeches, and see the Power Points that were presented by the speakers. More information will be posted as it becomes available.

These are a few of the many slides that I found interesting. This one, by Dennis Avery, puts the climate swings of the last 12,000 years (i.e., since the last Ice Age) in perspective; click to enlarge:

This one, by Syun Akasofu, also takes a long-term view, and compares the politically-driven prediction by the UN’s IPCC with the historical trend as the earth has recovered from the Little Ice Age:

Don Easterbrook makes the basic point that, contrary to the hysterical predictions of the alarmists, the earth is cooling, not warming:

This one by Dennis Avery shows the lack of any correlation between atmospheric CO2 and temperatures in the atmosphere:

Don Easterbrook compares the correlations of solar activity and CO2 concentration to temperature. It seems pretty obvious where the explanation for fluctuations in temperature lies:

Due to the efforts of Heartland and others, the public is beginning to catch on to the cosmic scam that Al Gore, James Hansen and others–mostly not scientists–have been perpetrating. Meanwhile, the Obama administration, seemingly determined to inflict the maximum possible damage on the economy in the shortest time, is trying to ram a cap-and-trade carbon tax through Congress before opposition can be mobilized. It’s easier to do that, of course, when you know that Congressmen won’t read the statute before they vote on it. So our only hope is an informed citizenry.
