Unless you have been living in one of the few truly remote areas of the planet, you have been exposed to them. Climate change memes that pass from person to person and are repeated without thought or critical examination. They range from the subtle—bad weather is being increased by global warming—to the banal—over 97% of scientists agree about climate change. We are bombarded with these unsubstantiated ideas over and over again, from talking heads on TV, newspaper headlines, our friends and even the president of the United States. They are blatant untruths that have become legitimized by repetition, until school children and adults alike patriot them to each other. The recent tropical cyclone, Haiyan, has triggered another round of meme infection: it was the worst storm in history, tropical storms are getting bigger every year, there are more storms every year, and, of course, they are all caused by global warming. Trouble is, these “facts” are all false.
The asteroid that exploded on 15 February, 2013, near the city of Chelyabinsk in the Urals region of Russia was the largest to fall to Earth since 1908. That was the year of the famed Tunguska blast in Siberia. This latest fireball exploded with the energy of a half megaton nuclear bomb, seven times the blast that leveled Hiroshima. Using updated information, new reports in both Science and Nature reassess the risk of Earth being impacted by a large object. The researchers found that risk of similar objects hitting our planet may be ten times larger than previously thought. It is time we stop wasting time and government money on stupid measures like windmills, solar panels and a carbon tax and do something about a very real threat to our planet.
Climate alarmists are constantly warning that Earth is going to warm up, driven they say by the level of CO2 in the atmosphere. To bolster their claims they point to the Pliocene, a time 4-5 million years ago, when the planet was 4-8°C hotter and CO2 levels were 400ppm or higher. This is the climate we are heading for, the global warming supporters say—but it that really true? Superficially it seems a plausible assertion, but as it turns out there is much more here than CO2 and temperature. It is not just the average temperature but the distribution of temperature at different latitudes, both over land and sea, that controls the climate. It is the temperature gradient that drives storms and affects weather patterns and it was much different during the Pliocene. Moreover, climate models do not generate a Pliocene like climate when run with higher CO2 levels, which means climate scientists are missing something important about the way Earth's climate system works.
You may have heard that Al Gore, the self anointed Prophet of climate doom, is holding a twenty four hour propaganda fest trying to frighten the public into wasting even more money on bogus climate change measures. “Join us as we go around the world, identifying the costs of carbon pollution and the solution that can change the course of our future,” the associated web site proclaims. Why are we telling you about this? Because highlighting the half truths and outright lies perpetrated by climate miscreants is the best way to expose the farce that is the radical green movement.
Nothing associated with the global warming scam has been more insidiously deceptive than the constant trumpeting of consensus regarding the cause and expected impact of climate change. In a cleverly disguised piece in the journal Nature, Harvard historian Naomi Oreskes has attempted to use the story of plate tectonics as an analog for anthropogenic global warming (AGW). The article is a blend of historical fact and illogic, aimed at giving the consensus science view a sheen of validity, when nothing could be further from the truth. Consensus has its place, primarily in politics, and by extension in history. It is unsurprising that Professor Oreskes embraces consensus while missing the fundamental concepts of science and the scientific method. She is an historian, not a scientist, and that difference can not be covered over by taking a poll.
The long awaited full text report is finally available. The Final Draft Report, dated 7 June 2013, of the Working Group I contribution to the IPCC Fifth Assessment Report Climate Change 2013: The Physical Science Basis was accepted but not approved in detail by the Twelfth Session of Working Group I and the Thirty-Sixth Session of the IPCC on 26 September 2013 in Stockholm, Sweden. This report consists of the full scientific and technical assessment undertaken by Working Group I. While the final draft of the underlying Working Group I report is still subject to copy-editing and corrections in proof as normally applied to scientific reports the fundamental tone and content of the report has been set. No screaming warnings; no predictions of impending doom. The most shocking thing is that our knowledge of climate change has not advanced in almost a decade. Simply put, climate scientists are puzzled by the way nature is acting.
There was a time when climate change alarmists stood confident in the approaching global warming apocalypse. Even a few years pause in the upward march of temperatures was shrugged off, the catastrophists smugly stating that it would take ten or more years without warming to throw a spanner into their disaster predictions. It has now been fifteen years without the promised meteoric rise in global temperatures predicted by the warmongering climatologists' computer models. Unsurprisingly, some of the anthropogenic global warming faithful have started to question current climate change dogma. In commentary in a journal dedicated to climate change, scientists have admitted that they've overestimated climate change for 20 years. What is more, they do not really know why their predictions have turned out so wrong.
Climate change has become the go to excuse for anything bad happening in the environment. Legions of climate scientists have issued dire warnings regarding the consequences of man's profligate use of fossil fuels. So common have these pronouncements become that news reporters and politicians have taken to blaming all things judged out of the ordinary on global warming. This fits the agendas of many, since global warming is supposedly caused by human activity and human activity is linked to greed, avarice and big business. But the doomsayers should take care, for there have been other times when experts have warned humanity that its evil ways have brought the world to the edge of perdition. Does anyone these days remember over population?
A 17-meter-wide asteroid that no one saw coming exploded in February near Chelyabinsk, Russia, blazing across the sky and television screens world wide. Efforts have been made to identify asteroids larger than a kilometer—objects large enough to threaten life on Earth. Hollywood has cranked out dozens of cheesy asteroid collision movies, some bad and others worse, but none capture the magnitude of the actual threat from near Earth objects (NEOs). There may be a million asteroids with masses greater than ocean liners in Earth-approaching orbits, nearly all of which remain undiscovered and their courses uncharted. Now, a private foundation wants to build Sentinel, a satellite containing an infrared telescope that would be able to detect a half-million orbiting objects from a vantage point near Venus. Is this a project too important to trust to government agencies like NASA and the ESA?
Scientists have long suspected that the orbital cycles of our planet are responsible for the periodic climate variation that causes alternating glacial and interglacial periods. Milankovitch's theory of orbital cycles suggests that summer insolation at high northern latitudes drives the glacial cycles. Moreover, statistical analyses have demonstrated that the glacial cycles are indeed linked to eccentricity, obliquity and precession. Now, researchers have confirmed that a combination of two of the Milankovitch cycles conspire to start and stop ice ages. The 100,000-year eccentricity cycle amplifies the influence of the 23,000-year wobble of Earth's spin axis called precession. The new modeling also suggests that the great accumulation of mass by the North American ice sheet causes the abrupt end of glacial periods. CO2 is involved, but is not determinative, in the evolution of the 100,000-year glacial cycles say the scientists.
Science is supposed to be unbiased, seeking to understand the workings of nature untainted by the personal beliefs or prejudices of its practitioners. Nature alone is the arbiter of truth—when science and nature disagree it is science that is wrong. But science is practiced by human beings, who cannot keep their beliefs, whether engendered by religious, philosophical, or political leanings, from skewing any result that is equivocal or highly complex. Presented here are two examples taken from the pages of Nature, perhaps the world's primer scientific journal. One is a rehash of temperature history in northern latitudes with a new statistical twist, the other a report on a study regarding fracking. One shows how what scientists leave out of their studies may be more important than what they put in. The other shows how a headline can spin the results of a report even when its authors are carefully neutral in their conclusions.
Much has been done to vilify carbon dioxide in the media. Listening to the talking heads and on-air “experts” could lead one to believe that CO2 is an evil scourge that the world would be better off without. Nothing could be further than the truth. CO2 is necessary for life on Earth, forests in particular. It is not just plant food, the maligned gas also plays a role in regulating water use by the world's forests. New research has uncovered an unexpectedly strong decrease in H2O uptake caused by increasing CO2. Along with global increases in photosynthesis, forest growth rates, and carbon uptake, higher CO2 levels contribute to enhanced timber yields and improved water availability. Who says higher CO2 levels are a bad thing?
They took their best shot, an all court press trying to convince the people of the world that climate catastrophe was imminent, that humanity had irreversibly fouled its own nest with billowing clouds of greenhouse gasses. Yet the world remains. There has been climate change aplenty, just not the climate change predicted by the IPCC's perfidious minions. More and more scientists have begun to face the fact that their climate model estimates are not correct, forced by nature itself to conclude that there is something fundamentally wrong with how climate science is done. In a recent edition of a major scientific journal, a gaggle of climate scientists have issued a statement that just a few years ago would have been considered heresy: “The rate of global mean warming has been lower over the past decade than previously.” This leads them to conclude that a lower range of temperature increase at the point of doubling of the atmospheric CO2 concentration is indicated.
Scientists who study climate will tell you that today's warm temperatures and mild conditions are not normal for Earth during the past several million years. Our planet has been in a general cooling trend for 35 million years and in the grip of an Ice Age for the last 1.6 million years. What's more, this Ice Age, known as the Pleistocene, consists of relatively short periods of warmth, called interglacials, separated by much longer periods of bitter cold, referred to as glacials. The recorded history of humankind covers only the later half of the most recent interglacial warming, though our ancient ancestors did leave messages in the form of cave art that date back to much colder times, times when the Ice Age held the world fast in its frozen embrace. Predicting the timing and duration of these periods remains a problem for scientists. Why the glacial periods should last around 100,000 years, as they have for the last million years or so, is called the 100-kyr problem. Now, a group of researchers claim they know the answer.
Most people have never heard of the Anthropocene era and with good reason—it is not an officially recognized geologic time period. It is the invention of a small group of scientific busy bodies who evidently have nothing better to do than try to effect a change in the official timeline of Earth's past. The International Commission on Stratigraphy, the body charged with formally designating geological time periods, has been petitioned in the past and just recently a group of chuckle-heads attending the Society for American Archaeology meetings in Hawaii have brought the idea up again. Only problem is, the proponents of the Anthropocene have fallen to arguing amongst themselves—when did the “Age of Man” really start?
