In a new study of coral reefs off the Pacific coast of Panama, a team of scientists has discovered something shocking: those seemingly thriving, permanent reefs have undergone widespread devastation in the past. Even more shocking was the realization that, despite this natural destruction of coral reefs, the reefs bounced back—after laying dormant for 2,500 years. We have been told that the oh so sensitive coral reefs of the world are all going to die if the world's temperature rises due to that horrible man-made scourge, global warming. Yet it seems that nature has been happily wiping out and re-establishing reefs across all the oceans of the world since before the rise of human civilization. Once again the warmists' scare tactics founder on the reefs of actual science.
The IPCC is working up to releasing pieces of its next climate report, starting in 2013. This has the world's climate scientists scrambling to get their latest work included in that dubious document. Foremost among those struggling for primacy of place are the computer modelers, those who study their own created worlds instead of the natural one around them. This report promises to be more contentious than the last one (AR4) in that the modelers have been racing to incorporate the effects of aerosols, soot and other airborne particulates that had previously been give scant attention. Early results suggest that aerosols have a much greater impact on regional climate than scientists had realized and that aerosols and clouds are providing some big surprises.
A new Current Biology paper proposes that the accumulated output of dinosaur flatulence could have changed the global climate during the age of the dinosaurs. Insert dinosaur fart joke here. No, seriously, this is a real report in an actual scientific journal. It just happens to be on a subject that the news media could not resist blowing out of proportion on their best day. Given that much of the CO2 in Earth's atmosphere was emitted by some form of living creature this is a serious area for study by environmental scientists. So after giving the chattering media magpies some time to calm down, here is a more serious take on this heady topic.
Carbon offsets, favored by PC Hollywood stars and green politicians alike, have been used by the rich and powerful as a way to make their energy wasting lifestyles appear to be OK from an ecological point of view. Al Gore and Leonardo DiCaprio have both used carbon offsets to greenwash their jet-setting travel on private aircraft. Airlines even offer the unwashed masses an opportunity to purchase carbon offsets before boarding a flight—you may not be able to fly like they stars but you can lie like the stars. Finally, a voice from the green ranks has spoken up to denounce carbon offsets for what they are: “carbon offsetting is without scientific legitimacy and is dangerously misleading.”
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?
The dire results of anthropogenic global warming have become passé. Treated by the news media and climate alarmists as established scientific fact, the IPCC's vision of a dystopian future, a world ravaged by global warming, is feed to our children in school, TV shows and Hollywood movies. What is never mentioned is that even the IPCC's predictions encompass several ranges of possible outcome, all predicated on a seemingly simple but mysterious factor called climate system sensitivity. A recent study, published in the journal Science, used spatially more complete paleoclimate data for the Last Glacial Maximum (LGM) in an effort to improve previous estimates of climate sensitivity. The new results have not been widely reported in the news media because, according to the researchers, “these results imply a lower probability of imminent extreme climatic change than previously thought.”
Climate-impact models combine projections of change in physical climate with data on population, economic growth and other variables. The output of such models are used to make predictions regarding the cost of anthropogenic global warming, in both monetary and human terms. They are the source of dire predictions used to scare politicians and bludgeon the public into accepting draconian measures to curb human CO2 emissions. Unfortunately for the prophets of climate change catastrophe, the models' reports are far from being in agreement, leading more rational members of the public to doubt the models' veracity. To rectify this lack of believability, a new “fast-track” program to coordinate modeling studies and make “their narratives of possible futures more coherent and useful to decision-makers,” has been launched. In other words, it is an attempt to make sure that climate change propaganda is at least consistent.
A new theory of supercontinent formation, published in the journal Nature, predicts that the Arctic ocean will be squeezed out of existence in the future as most of Earth's landmass gathers in a new supercontinent—Amasia. The new orthoversion helps to resolve the problems of the older introversion and extroversion models, which have led to a “fundamental disconnection … between the geologic evidence for supercontinent formation, and the models purported to explain their assembly.” If the Arctic Ocean disappears so will the Polar Bear, an iconic species that has been held up as a poster child for global warming. The climate catastrophists are correct in predicting the demise of the white bear of the Arctic, but they have both the reason and time frame terribly wrong.
Many of the more strident reports regarding runaway global warming center on rapid ice loss from the glaciers of Greenland. During the early 2000s the Greenland Ice Sheet experienced the largest ice-mass loss since accurate instrument readings have been kept. This was largely caused by the acceleration, thinning and retreat of large outlet glaciers in West and southeast Greenland. Now a new study in Nature Geoscience confirms that ice loss from the Helheim Glacier between 2003 and 2005 was the worst recorded—at least since the last period of rapid ice loss during the late 1930s.
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.
Towering pyramids and ceremonial plazas are the hallmarks of ancient Mesoamerican urban building, yet the oldest examples that call to mind this familiar style are found nearly 1000 kilometers to the north in the muddy bayous of Louisiana. Five millennia ago, Native Americans began to build high mounds of earth flanked by flat plazas that resemble the classic architecture of the Maya and the Aztec. Surprisingly, new dating efforts reveal that the first great period of mound building nearly occurred 5,000 years ago—nearly 2,000 years before the first cities appeared in Mexico, and before the Giza pyramids in ancient Egypt. Stranger still is what brought this golden age of prehistoric Native American culture to an end: a five century long spell of massive floods in the lower Mississippi Valley.
An iceberg the size of Berlin is forming in Antarctica and is expected to break off from the Pine Island Glacier soon. As sure as night follows day, climate change alarmists will pronounce this a result of anthropogenic global warming—and they will be dead wrong. NASA scientists have already predicted the event and proclaimed it a part of a natural, ten year cycle that they have been studying for decades. The sad state of climate science is underlined by the fact that the researchers felt compelled to state that global warming is not the cause of the ice-shelf collapse.
Starting on January 1, 2012, airlines flying to and from airports in the European Union (EU) will be forced into an emissions trading system that attempts to regulate CO2. The announced intention of this draconian cap-and-trade system is to save the world from the imagined ravages of anthropogenic global warming (AGW), but given the dire financial straits much of Europe finds itself in there is little doubt that Eurocrats will view this new policy as a potential source of revenue. Unfortunately, the new regulation threatens the entire structure of international air travel by unilaterally violating agreements that have been negotiated over decades. In seeking to avoid the imaginary dangers of global warming, the EU threatens the global air transport system with a very real CO2 Armageddon.
The Nobel Prize in Chemistry for 2011 has been awarded to Daniel Shechtman of the Technion, the Israel Institute of Technology in Haifa, for the discovery of quasicrystals. Quasicrystals are non-repeating regular patterns of atoms that were once thought to be impossible. Most people would agree that this is the type of unexpected discovery that deserves a Nobel Prize, but this is not just the story of an amazing scientific revelation. After first discovering evidence for quasicrystals in 1982, using an electron microscope in a US government lab, Shechtman was expelled from the lab and subjected to years of ridicule by other scientists. You see, quasicrystals were thought impossible by crystallographers at the time and even though Shechtman had evidence backing his claim, he was ostracized by mainstream science.
Nostradamus, the famous prognosticator, was said to have received his visions of the future by scrying—staring into a pool of ink for hours on end. The climate science equivalent of a gazing pool is the computer climate model, huge collections of complicated computer code that supposedly crank out frightening visions of the future. Most of the discussion about climate change has centered on the global aspects of the anthropogenic global warming (AGW), but now a number of climate mystics are turning their modeling dark arts to doing regional predictions. Why? The better to frighten the public and elicit funding from government coffers. Unfortunately, as climate researchers struggling to sharpen their fuzzy picture of what the future holds one fact has been ignored—there is even more uncertainty in regional models than in the global ones.
