DNA evidence lifted from the ancient bones and teeth of people who lived in Europe from the Late Pleistocene to the early Holocene -- spanning almost 30,000 years of European prehistory -- has offered some surprises, according to researchers who report their findings in the Cell Press journal Current Biology on Feb. 4, 2016. Perhaps most notably, the evidence shows a major shift in the population around 14,500 years ago, during a period of severe climatic instability... The researchers pieced this missing history together by reconstructing the mitochondrial genomes of 35 hunter-gatherer individuals who lived in Italy, Germany, Belgium, France,...

In Heaven + Earth (Global Warming: The Missing Science), Ian Plimer, Professor of Mining Geology at The University of Adelaide, Australia, asks us to embrace big-picture science views; for to recognize our limits is a sign of maturity. "Climate science lacks scientific discipline," says the pro-amalgamation Professor, and in order to see more clearly we need to adopt an interdisciplinary approach. This requires humbleness. In Chapter 2: History, Plimer travels back in time, thousands of years, in fact, to debunk Gore's catastrophic global warming myths. I particularly like his research on the ancient Greeks. For Plato (427-347 BC) advanced the...

In our information age, we’re bombarded with statistics on every danger the number crunchers can conjure — people struck by lightning, airplane vs. automotive deaths, and even drownings in bathtubs. But one statistic is curiously missing from the list. Even though President Obama and other global-warming alarmists warn of a looming climate apocalypse, they avoid giving a metric to prove their claims. They blame man-made climate change for a vast array of ills, including floods, droughts, wildfires, and tornados. But they never quantify what they say is the driving force behind it all: temperature.They have a very good reason. Actual...

Controversy over what sparked the Younger Dryas, a brief return to near glacial conditions at the end of the Ice Age, includes a theory that it was caused by a comet hitting the Earth. As proof, proponents point to sediments containing deposits they believe could result only from a cosmic impact. Now a new study disproves that theory, said archaeologist David Meltzer, Southern Methodist University, Dallas. Meltzer is lead author on the study and an expert in the Clovis culture, the peoples who lived in North America at the end of the Ice Age. Meltzer's research team found that nearly...

(Abstract only) Significance We present detailed geochemical and morphological analyses of nearly 700 spherules from 18 sites in support of a major cosmic impact at the onset of the Younger Dryas episode (12.8 ka). The impact distributed ∼10 million tonnes of melted spherules over 50 million square kilometers on four continents. Origins of the spherules by volcanism, anthropogenesis, authigenesis, lightning, and meteoritic ablation are rejected on geochemical and morphological grounds. The spherules closely resemble known impact materials derived from surficial sediments melted at temperatures >2,200 °C. The spherules correlate with abundances of associated melt-glass, nanodiamonds, carbon spherules, aciniform carbon, charcoal,...

Emergence of a new picture of the Maltese holocene environment A new picture of the Maltese holocene environment is emerging through Katrin Fenech’s recent Ph.D. thesis entitled “Human-induced changes in the environment and landscape of the Maltese Islands from the Neolithic to the 15th century AD, as inferred from a scientific study of sediments from Marsa, Malta”. The thesis investigates current theories through scientific analyses of sediment. For this purpose, an 11.2m long sediment core was retrieved from the Marsa Sports Ground, with the help of a mechanical corer, in June 2002, financed by Linda Eneix of the OTS Foundation....

The climate of the current interglacial, i.e., the Holocene, exhibits a millennial-scale oscillation that has resulted in several-hundred-year alternating warm and cold periods, the most recent of which is the Modern Warm Period that many people are telling us is due to the CO2-emitting activities of man. Before this claim is accepted, however, it would seem only prudent to determine if there is any evidence for similar warm periods in earth's recent history that were clearly not man-induced. If there were some such warm periods, for example, there would be no reason to accept the climate-alarmist claim that human activities...
