POPSNew Mexican Cave Hints at Future Weather Chemical changes in the calcite layers of a 56,000 year old stalactite show whether moisture came from wintry Pacific Ocean storms or annual summer Gulf of Mexico rains. Comparing this data with Greenland ice core samples shows that global warming causes the jet stream to retreat northwards. Of interest is the implication that global warming is cyclic and older cycles may indicate what we can expect in this current cycle.

POPSClimate Change: Back to the future? 
There are many factors influencing climate. Variations in solar cycles, solar radiation deflection/absorption, the earth's core, ocean currents, complicated climate cycles, urban islands, rain forest depletion in some regions, reforestation in other regions and volcanic eruptions are just a few. The influence and interaction of all these factors and many more are much too complex to model precisely enough to draw conclusions about temperature rises and drops next month, much less next century. According to the best scientific evidence available, much of our planet has been buried under ice for most of the last million years. The duration of the ice ages was about 100,000 years, the most recent beginning approximately 114,000 years ago when global temperatures abruptly plummeted. Just as suddenly, about 10,000 years ago the planet warmed and glaciers receded. I checked, and there were no coal-burning fuel plants or SUVs in 8000 BC, but that will, of course, not deter the climate a

POPSThe mini ice age starts here Ok...can we be done with this decades long man-made climate change propaganda and start dealing with the here & now? China is economically starting to take over the world, the US is in debt up to our great-grandchildrens' eye-balls, and we need to produce our own sources of energy. Stop funding fake science and environmental fears. Allow our entrepreneurs to meet the practical needs of Americans...and don't take my LIGHT BULBS!

POPSFacts for Predicting Global Cooling for the Next Three Decades Global warming (i.e, the warming since 1977) is over. The minute increase of anthropogenic CO2 in the atmosphere (0.008%) was not the cause of the warming—it was a continuation of natural cycles that occurred over the past 500 years. The PDO cool mode has replaced the warm mode in the Pacific Ocean, virtually assuring us of about 30 years of global cooling, perhaps much deeper than the global cooling from about 1945 to 1977. Just how much cooler the global climate will be during this cool cycle is uncertain. Recent solar changes suggest that it could be fairly severe, perhaps more like the 1880 to 1915 cool cycle than the more moderate 1945-1977 cool cycle. A more drastic cooling, similar to that during the Dalton and Maunder minimums, could plunge the Earth into another Little Ice Age, but only time will tell if that is likely.

POPSScientist: CO2 Not Causing Climate Change the world has experienced three periods of cooling since 1850 and furthermore carbon dioxide was increasing during many of those cooler periods. "If we had only had warming, then there would be a connect between co2 and temperature, there is not," he added. Prof Plimer has come under attack as a "denialist poster boy" whose theories are in danger of stopping the world from tackling the grave dangers of climate change. But he said the scientists "frightening people witless by following the party line" are motivated by politics and research funding. "They are taking advantage of the current situation. That is understandable. In previous times people got wonderful research grants in a war against cancer and they achieved a lot of money for that. Now we have a war on climate change and we have a huge number of people out there who have their career staked on it and are beneficiaries of this process."

POPSAn Open Letter to the Council of the American Physical Society Studies of a variety of natural processes, including ocean cycles and solar variability, indicate that they can account for variations in the Earth’s climate on the time scale of decades and centuries. Current climate models appear insufficiently reliable to properly account for natural and anthropogenic contributions to past climate change, much less project future climate. The APS supports an objective scientific effort to understand the effects of all processes – natural and human --on the Earth’s climate and the biosphere’s response to climate change, and promotes technological options for meeting challenges of future climate changes, regardless of cause.

POPSThe BBC's amazing U-turn on climate change The oceans, he says, have a cycle in which they warm and cool cyclically. The most important one is the Pacific decadal oscillation (PDO). For much of the 1980s and 1990s, it was in a positive cycle, that means warmer than average. And observations have revealed that global temperatures were warm too. But in the last few years it has been losing its warmth and has recently started to cool down. These cycles in the past have lasted for nearly 30 years.

POPSMachu Picchu Described as Pilgrimage Site
The author of "Mysteries and Discoveries of Archaeoastronomy," Magli suggests that the ceremonial path into the city was conceived as a replica of the path followed by the first Incas in cosmological myth. In their final leg, the pilgrims approached three important places: the so-called quarry, an area possibly connected with Mother Earth and the underground travel of the first Incas, the temple of the three windows (it was believed that the first Incas came out from one of the three windows), and the Intihuatana Pyramid, which resembled the sacred mountain Huayna Picchu, located at the end of the path. According to Magli, the picture also fits with celestial cycles that appeared in the sky at the times of the Incas. These were dominated by the Milky Way, which was perceived as a "celestial river" having its terrestrial counterpart in the Urubamba River. "Machu Picchu was located at the ideal, opposite crossroads between the terrestrial and the celestial rivers. It was

Natural variability and greenhouse gas emissions (and the resulting rise in global temperatures) likely worked together to melt greater amounts of arctic sea ice. Some models forecast and ice-free arctic for part of the year before the end of the 21st century

POPSGlobal Cooling OK, I just liked this one...the article is longer than I could clip, but an interesting read. The heating/cooling cycles of the earth are documented and while we contribute to pollution and we should be looking for alternative fuels, we are not going to destroy the Earth as soon as some would like us to believe.

POPSEarth On The Brink Of An Ice Age
Elements of the astronomical theory of Ice Age causation were first presented by the French mathematician Joseph Adhemar in 1842, it was developed further by the English prodigy Joseph Croll in 1875, and the theory was established in its present form by the Serbian mathematician Milutin Milankovich in the 1920s and 30s. In 1976 the prestigious journal “Science” published a landmark paper by John Imbrie, James Hays, and Nicholas Shackleton entitled “Variations in the Earth's orbit: Pacemaker of the Ice Ages,” which described the correlation which the trio of scientist/authors had found between the climate data obtained from ocean sediment cores and the patterns of the astronomical Milankovich cycles. In 1999 the British journal “Nature” published the results of data derived from glacial ice cores collected at the Russia’s Vostok station in Antarctica during the 1990s. The Vostok ice core data includes a record of global atmospheric temperatures, atmospheric CO2 and other

Since the late 1970s, the Milankovich theory has remained the predominant theory to account for Ice Age causation among climate scientists, and hence the Milankovich theory is always described in textbooks of climatology and in encyclopaedia articles about the Ice Ages.

POPSMapping the Bio Cosmos Microbes are responsible for many biogeochemical cycles and are crucial to the continued function of the , Woese's efforts to clarify the evolution and diversity of microbes provided an invaluable service to ecologists and conservationists. Woese’s big idea is that primitive life existed as a community of cells that freely exchanged genes. They shared a basic translation system for making proteins, but had little else in common. These cells evolved as a community and not as distinct lineages. Before Woese, the tree of life had two main branches called prokaryotes and eukaryotes, the prokaryotes composed of cells without nuclei and the eukaryotes composed of cells with nuclei.
