Gas prices, oil sands, fracking and the Canadian pipeline have all thrust energy back into the headlines. Politicians posture, eco-alarmists protest and those global warming fanatics continue to predict the end of the world as we know it. If you are tired of the hype and disinformation, if you really want to understand energy—where it comes from, how it works and how much of it the world has—then you need a copy of The Energy Gap. In this follow-on to The Resilient Earth, Hoffman and Simmons address the world's energy questions with the same wit and erudition displayed in their previous work. Even better, in honor of April 15th, tax day in the US, you can now download a copy of The Energy Gap for free from Amazon.
The Resilient Earth Press is proud to announce Doug L. Hoffman and Allen Simmons' seminal work, The Resilient Earth, is now available in a re-formatted version for the Kindle ebook reader. As relevant today as when it was first published in 2008, this new version contains the entirety of the text from the original paperback edition, reformatted to more effectively display on Amazon's new line of color Fire HD readers. The price has also been reduced to $7.99, a savings of 60% over the the hard copy list price. More than just a book about global warming, it is a tribute to nature and the scientists who study the Universe we live in. If you do not own a copy of this classic, now is the time to buy REP's all time best seller.
It has been vilified in the press and maligned in school classrooms by the ignorant. Opposing it has become a cause célèbre in Hollywood an a litmus test for liberal politicians. Labeled man's chosen weapon for ravaging nature and laying waste to the environment this poor, largely misunderstood gas is in fact essential to our existence. Without carbon dioxide, CO2, we would not be here and Earth would be a frozen lifeless chunk of rock. Forget that life would never have developed on a planet without greenhouse warming, a recent scientific study say the daemon gas has rescued the planet from the deep freeze at least twice during the Neoproterozoic era, roughly 750 to 635 million years ago.
A new “comprehensive” report about the melting of Antarctic and Greenland ice sheets is being touted by climate alarmists as “grim news” but in fact says no such thing. This latest estimate, published this week in Science, combines data from many sources including 20 years of satellite data and 32 years of ice-sheet simulations to arrive at a mixed conclusion. It estimates that, between 1992 and 2011, the Antarctic and Greenland ice sheets lost 1350 ± 1010 and 2700 ± 930 Gt of ice, respectively. That is equivalent to an increase in global mean sea level of 11.2 ± 3.8 mm, less than 1/2 an inch. Moreover, while some areas were losing ice mass others were gaining mass from snowfall. The East Antarctic Ice Sheet (EAIS), which occupies over 75% of Antarctica, experienced mass gains during the final years of the study.
For half a century, climate scientists have been attempting to simulate the workings of Earth's climate system in computer models. Over that period of time computers have increased in computational power a million fold, allowing models to grow in complexity and, if you accept the word of the modelers themselves, accuracy. Today's models may produce more realistic output but that should not be confused with more accurate output—modern climate models are still unable to accurately predict future fluctuations in Earth's environment. Why this should be so is highlighted in a new paper published in the Journal Of Advances In Modeling Earth Systems (JAMES), a publication of the American Geophysical Union. In it the tuning secrets of those modern-day mystics, climate modelers, are revealed.
Climate change alarmists point to the past several decades of European weather to reinforce their claim that global warming has the continent in its grip. A new report shows that this recent warm spell is nothing abnormal or unprecedented—during the 1990s there was simply a return to conditions present during 1931-1960. The reason for the shift is warm ocean temperatures that are, in turn driven by variation in warm ocean currents from the tropics. The instrumental record shows that, relative to the average temperature of the rest of the world’s oceans, the temperature of the North Atlantic Ocean has fluctuated between anomalously warm and anomalously cool phases, each lasting several decades at a time. Palaeoclimate records suggest that similar variations extend much farther back in time. The observed pattern of multidecadal variation in North Atlantic sea surface temperatures (SSTs) has become known as the Atlantic Multidecadal Oscillation (AMO).
Science is fairly certain that there were “vegetarian cavemen,” but they didn't last. There was a pre-human species of man, who lived around 2.7 million to 1 million years ago, that many scientists think existed on a vegetarian diet. New research shows that the vegetarian branch of ancient humans died off long ago, while their meat-eating cousins lived on and thrived. The dietary specialization of this vegan leaning branch of early hominin is thought to have contributed to its demise because it was unable to adapt to the changing environmental conditions that took place approximately 1 million years ago. Perhaps there is a message in this for today's vegetarians—eat meat or you too will become extinct.
There has been a wave of triumphal announcements by climate change proponents recently, almost giddy over the summer shrinkage of the Arctic ice sheet. “Lowest level ever!” they proclaim, thought that is not quite true. Nonetheless, The Arctic pack ice has been receding over the last decade or so, but that is only natural. You see, there is a well known, if poorly understood, linkage between the ice at the north pole and the ice in and around Antarctica—and the ice around Antarctica is doing quite well. Satellite radar altimetry measurements indicate that the East Antarctic ice sheet interior increased in mass by 45±7 billion metric tons per year from 1992 to 2003. This trend continues today, reinforcing recent scientific investigations into this millennial scale oscillation between the poles. According to studies, this is how things have been for hundreds of thousands of years.
A study of ancient volcanic ash found at key archaeological sites across Europe suggests that early modern humans were more resilient to climate change and natural disasters than commonly thought. The study, which appeared in PNAS, analyzed volcanic ash from a major eruption that occurred in Europe around 40,000 years ago. The volcano spewed so much ash that the event probably created winter-like conditions and a sudden colder shift in climate. Scientists have generally suggested that the spread of modern humans, and the decline of our cousins the Neanderthals, was primarily due to ancient volcanic eruptions and deteriorating climate conditions, but this study shows that stone-age man rolled with the punches and shrugged off the sudden shifts in climate. This new evidence flies in the face of modern predictions that a shift of a few degrees in average yearly temperature will decimate human populations world wide.
A new study in the Proceedings of the National Academy of Sciences (Early Edition on-line), is shaking up science's view of polar bear evolution. Previously, it had been suggested that the white bear of the north was a relatively young species that diverged from brown bears during the last glacial period. That glaciation started after the Eemian epoch (~125,000 years ago), peaking around 25,000 years ago. New genetic analysis pushes that estimated divergence back to 4-5 million years ago, though there seems to have been a significant level of interbreeding between the two species over time. Another important finding is that the polar bear population underwent a significant contraction around 500,000 years ago. According to this new information the polar bear has been around for much longer than previously thought, implying that it has survived many interglacial warm periods. In other words, those who think the polar bear cannot survive the shrinking of Arctic ice packs are dead wrong.
The coyote, also known as the American jackal or the prairie wolf, is a canine predator found throughout North and Central America. Ranging from Panama in the south, north through Mexico, the United States and into Canada the wily Canis latrans has been spreading into new territory in the Eastern US, filling a void left at the top of the food chain by the virtual extinction of the gray wolf. But these new coyotes are not the little dog sized creatures from the South West—the new coyote is larger, stronger and more aggressive than his ancestors. Well known as a master of adaptation, new studies over the past few years are now revealing how these relatives of wolves and dogs are evolving into a new top predator thanks to humans. They have expanded their diet to include squirrels, household pets and even deer. Supposedly, coyotes killed a 19-year-old female hiker in Nova Scotia in 2009. It seems that this new breed of predator is actually a wolf in coyote's clothing.
Just when it looked like the climate catastrophists had slunk back into well deserved academic obscurity, a new report in the journal Nature Geoscience has resurrected claims of Earth's impending climatic demise. A new computer climate study says to expect increases in temperature of up to 3°C by 2050, confirming or exceed predictions made by the IPCC reports. Can this model based report be considered any more accurate than previous attempts? Have modeling techniques suddenly improved? Or is this report's appearance in a major scientific journal the signal of a renewed round of scaremongering by eco-alarmists?
Those who thought that the war was won and the forces of junk science—who prop up the climate change alarmists—were sent packing need to think again. With the new year, a new assault on climate skepticism is being waged on multiple fronts. Editorials in Nature and Science herald the resurgence of the climate catastrophists and their attempt to bamboozle the public, mislead government officials and brainwash our children. Wake up and smell the steer manure, the battle against the bogus boffins of climate hysteria is far from over.
In 2009, the International Commission on Stratigraphy, the body charged with formally designating geological time periods, decided the Anthropocene concept “has some merit.” To investigate further they formed the Anthropocene Working Group, which published their initial findings this past February in a special issue of the Philosophical Transactions of the Royal Society A. The group reported a wide range of human impacts that could leave a stratigraphically significant mark on the planet's geological record. There is no doubt that humans have changed the world we live in, but has the change been significant enough to declare a whole new epoch? The Anthropocene debate is continuing this week at the 2011 Geological Society of America conference.
No phenomenon in astronomy has been studied more closely than solar flares, gigantic eruptions on the Sun that can affect Earth's climate and even disrupt power grids. Scientists have been watching the Sun with ground based instruments and orbiting satellites for years, so it might be thought that we know a lot about such eruptions. Well think again. A new report from NASA has revealed that, like earthquakes, solar flares often have aftershocks. Moreover, the aftershocks can emit bursts of ultraviolet (UV) radiation more powerful than the original eruption. Combine this new finding with the recently uncovered linkage between fluctuating UV levels and El Niño, and the Sun-Climate connection looks stronger than ever.
