Scientific Societies Err on ‘Climate Change’

By Wallace Manheimer

Major scientific organizations’ statements on “climate change” and the conclusions therein form the basis of much of the scientific foundation for governmental, scientific, media, and public concerns on the use of fossil fuels. Trillions of public and private dollars are currently being spent on alternative fuels to “save the planet” from the alleged harm of increasing CO2, a gas which is vital for life on earth. If the evaluations of these societies are erroneous, these measures could impoverish much of the world, to say nothing of wasting trillions. Economic damage and social unrest are already evident in some countries, including the United States. It is therefore imperative for all that their views be based on sound science, and if not, these societies should change their statements.

A recent publication and podcast have examined the scientific organizations’ climate statements, and have found numerous errors, errors which are easy to find by simply comparing the societies’ statements with data from such reliable sources as NOAA, NASA, and others. These societies are the American Physical Society (APS), American Meteorological Society (AMS), National Academy of Science (NAS), American Chemical Society (ACS), and American Geophysical Union (AGU).

Here is one example. The AGU states “Greater CO2 concentrations in the atmosphere are also affecting the growth and nutritional value of land plants…” Numerous studies, including measurements of terrestrial plant life from space, and measurements of crop production, have shown that if anything, increasing CO2 has increased both plant life and crop production. After all, CO2is a vital nutrient for plants, and the slight warming we have experienced, possibly in part due to the increased CO2, has increased the growing seasons in the temperate latitudes.

As another example, the ACS statement asserts: “Extreme weather and related events, such as floods, droughts… are increasing in frequency and intensity, threatening Americans’ physical, social, and economic well-being.”. The frequency and intensity of floods and droughts is measured by what is called NOAA’s Palmer drought index and this index is displayed as a graph of index versus year. It shows clearly, that in the United States the worst sustained droughts in the U.S. were in the 1930s and 1950s, and the worst sustained floods were in the 1970s through the 1990s.

Tens of thousands of scientists, including over 10,000 with Ph.Ds., have critically examined the evidence, and have concluded that a CO2-induced climate crisis is extremely unlikely. They have willingly and publicly asserted this, by adding their names to documents such as, the Oregon petition, Clintel Climate Petition, and the CO2 Coalition. Among other things, the societies should not ignore these, professional conclusions of many of their members.

Accordingly, and with humility, I suggest that these societies do the following:

1. Replace their climate statements with ones that say there is most likely an effect humans have on the changing climate, but its importance for humanity is uncertain and it is still being debated.
2. Eliminate statements that are demonstrably incorrect, as shown by comparison with easily available and reliable data.
3. Acknowledge in their statements that fossil fuels cannot be replaced in the next several decades without greatly endangering our civilization.
4. Acknowledge in their statements that CO2 has obvious benefit for human existence, as well as potential risks.

By changing their statements to ones that are more moderate and scientifically correct, these societies will not only be helping the professions they serve, but more important, will ultimately be aiding humanity. On the other hand, if they keep their statements as they are, they will remain on the wrong side of history, and posterity will not look kindly on them. And posterity may be arriving sooner than they think. With a Republican Congress and President Trump referring to the “green new scam,” these society presidents may find themselves hauled before Congress to receive the university president treatment.

After all, the APS statement says, “Multiple lines of evidence strongly support the finding that anthropogenic greenhouse gases have become the dominant driver of global climate warming observed since the mid-twentieth century.” What will its president say when the congressman puts up a graph showing that for 30 years in the early decades of the 20th century, the warming rate was the same or greater? Or when he puts up a map proving that the northern forests, 4000 years ago extended about 200 miles further north worldwide than they do today. Or shows that 2000 years ago, the Romans had vineyards in England extending all the way to Hadrian’s wall, millennia before cold weather grapes had been developed. Or when he shows evidence that 1000 years ago the Vikings grew barley in Greenland, something not possible today. Surely this proves that the world had many warmer periods without the help of extra CO2 in the atmosphere.

There are many such statements that Congress can quote, to very publicly humiliate these society presidents. As a committed life fellow of the APS, I hope these societies will change their statements now, before the roof collapses on them.
