Well, the global warmers are at it again, with half-truths and distortions. A recent Associated Press article stated, “2014 considered the warmest year on record,” and ended with this: “‘Temperatures have risen by about 1.6 degrees Fahrenheit since the mid-19th century and pre-industrial times,’ said Gavin Schmidt, director of NASA’s Goddard Institute for Space Studies.”

Mr. Schmidt deliberately left out the rest of that observation, which should have included the fact that “current temperatures are still somewhat cooler than a thousand years ago, during the Medieval Warm Period.” Now, why would the director of NASA GISS leave out something that important? Perhaps he included that observation about the Medieval Warm Period, and the AP writer just left it out? Either way, the whole truth was not given in this AP article.

Recent studies, by scientists from China and the USA, examined very finely stratified growth rings in the giant clam Tradacna gigas from the South China Sea. These growth rings point to a very thought-provoking question about current “global warming.” The scientists found that “the mean SSTs (sea surface temperature) around AD 990 (plus or minus 40) and AD 50 (plus or minus 40) were 28.1 Celsius and 28.7 C, 0.8 C and 1.4 C higher than that during AD 1994-2005, respectively.”

Thus, at least near China, sea surface temperature now is lower than 1,000 and 2,000 years ago. Warmer seas at that ancient time might suggest the globe was warmer then than now. Exactly right.

The same team of scientists concluded that the observed varying patterns of seasonal temperature changes disproved “the notion that until the warming of the 20th century there had been little change in global temperatures for at least 1,000 years.” One might summarize their findings like this: The globe was about as warm 1,000 or 2,000 years ago as it is now.

Obviously, the globe cooled during the Little Ice Age, about 1650 to 1850 AD. That cool period ended at about the time chosen by the director of NASA GISS as “pre-industrial times.” No wonder the globe is somewhat warmer now than 150 years ago!

In the LIA, glaciers expanded in the Swiss Alps, wine grapes in England died from cold temperatures and giant clams in the South China Sea grew only slowly. Many scientists today point to a decrease in solar activity as the root cause of such cool temperatures. They also point out that the current inactive state of the sun may indeed be an indication of a return to colder climates.

This would be bad news, because about twice as many people die from cold compared to heat, because “almost all (cold-related deaths) are due to common illnesses that are increased by cold.” Economic growth helps prevent such deaths, because as noted in Slate magazine, “the fruits of economic prosperity — such as more people using toasty warm private cars instead of drafty public transportation and being able to afford heat for their houses — are gradually reducing the levels of wintertime excess deaths in relatively mild climates.”

But you will not hear any of that from NASA GISS, nor from the AP, apparently. They do not like what you just read, so they will not tell you about it. I do not trust them to tell the truth.
