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.
A study commissioned by the California legislature has just reported that, in order to achieve the state's aggressive greenhouse gas (GHG) emissions reductions by 2050, the golden state will need to more than triple the percentage of electrical power it gets from nuclear energy. In the January 6, 2012, issue of the journal Science a paper outlining the report's findings was published and they may be a bit unsettling for deep green Californian ecologists. It finds that technically feasible levels of energy efficiency and decarbonizing the state's energy supply alone are not good enough. The answer? Here is a hint—electric vehicles powered by expanded nuclear energy.
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.
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.
Given that the Sun powers Earth's climate system and provides the energy for all life on our planet, it should come as no surprise that changes in solar activity can affect climate conditions. Because total solar irradiance varies only slightly, climate scientists have discounted our variable star as a driver of climate change. At the end of the 20th century, Heinrich Svensmark, of the Danish Space Research Institute, and Eigil Friis-Christensen proposed that solar activity may be a controlling factor for climate by changing low level cloud cover. Not surprisingly this idea was disparaged by mainstream climate science, since it would diminish the importance of greenhouse gases, CO2, the IPCC's favorite daemon, in particular. Now, after several years of experimentation at CERN, the preliminary results are in and it looks like Svensmark and Friis-Christensen were right after all.
Tracking the flow of ice in the Arctic is difficult. Reconstructing the extent and flow in times past is even more difficult. An interesting new report has turned to driftwood, embedded in the Arctic pack ice, as a way of deciphering Arctic climate conditions over the last 10,000 years. The researchers found a climate record that is in good agreement with previous histories, including such events as the Medieval Warm Period, the Little Ice Age and the Holocene Thermal Maximum. In fact, they found temperatures during the HTM to be 2° to 4°C higher than today. They also found a complementarity oscillation in sea-ice abundance between East and West that is not correctly simulated by current ice models.
Recently, a US Federal Court ruled that placing polar bears on the endangered species list in 2008 was justified because it was based on the science available at the time and thus met the letter of the law. Yet the Polar Bear Specialist Group of the International Union for the Conservation of Nature (IUCN) has issued a report indicating that there was no change in the overall global polar bear population in the most recent four-year period. Nonetheless, a Federal Judge ruled that, even though the EPA's action was based on bad science, the misclasification was justified. As Dickens' put it in Oliver Twist: “If the law supposes that, the law is a ass — a idiot.”
Much fanfare was associated with the reappearance of sunspots earlier this year, marking the beginning of a new period of high solar activity. Now come a number of reports saying the Sun is most likely headed for a prolonged period of low activity, possibly rivaling the Maunder minimum. Three independent studies of the Sun's dynamics all predict that the next solar cycle will be significantly delayed and might even be skipped. The Maunder minimum is associated with a prolonged period of climate cooling known as the Little Ice Age. Whether Earth's climate is headed for a significant cooling trend has become a matter of heated debate, while at the same time NASA is warning that a quite Sun can also be a deadly Sun. In the 1850s, following a period of low sunspot activity, the largest coronal ejection event ever witnessed caused havoc with telegraphs and ship's compasses around the world. Such an ejection today could cause widespread power outages and failure of electronic equipment. Will our star turn both quiet and deadly?
After decades of trying to argue the case for catastrophic human caused climate change, aka global warming, based on its scientific merits, AGW proponents are now shifting their focus to a more abstract argument. Instead of trying to establish a causal relationship between human CO2 emissions and the planet's modest warming trend, the new tactic is to re-brand global warming as a moral dilemma. Because the perceived problem is global in scope and the science so tentative, the result of the debate so far has been distributed blame and inequitable impact on the world's poor. According to a new book, this leads to a kind of moral corruption where we let ourselves be persuaded by weak or deceptive arguments, with disastrous consequences for our ability to act on climate change. Can not acting in response to wild speculation based on incomplete science be immoral? Can actions based on a lie be moral?
The ineffective and mostly ignored Kyoto agreement is due to expire in 2012. Climate change activists around the world are girding their loins in preparation for the battle over Kyoto 2, the follow on treaty. Their goal? New regulations for black carbon, methane and driving anthropogenic CO2 emissions to zero. Leaving no bad idea unused, there is talk of implementing a global cap & trade system where developed nations that are able to reduce emissions beyond their Kyoto targets can sell excess reduction credit to other developed nations through the Emissions Trading mechanism. Beyond that, rather than negotiating CO2 emission reduction targets on a nation-by-nation basis—as in the current Kyoto framework—a future level of maximum allowable global temperature increase can be chosen. It is clear that the warmists have made the transition from irrational to delusional.
According to a new report from the American Physical Society, Direct Air Capture (DAC) of CO2 using chemicals is not a viable solution for removing greenhouse gases from Earth's atmosphere. DAC involves a system in which ambient air flows over a chemical sorbent that selectively removes the CO2. It is one of a small number of strategies that advocates say could allow the reduction of atmospheric CO2. Prepared for the APS Panel on Public Affairs (POPA), a collection of scientific experts, the report claims to be a technology assessment containing no policy or funding recommendations. Unfortunately for its advocates, the APS report finds the approach untenable for technical reasons.
Methane is an important greenhouse gas, 30 times more potent than CO2, but our knowledge of the methane cycle is woefully inadequate. Sediments on the ocean's floor contain immense quantities of methane and there are enormous fluxes of methane into and out of these sediments. Trapped frozen in ice, there are some 10,000 gigatons of carbon stored under the sea—twice as much carbon as contained in conventional fossil fuel reserves. Some scientists consider the release of this methane the single worst environmental danger we face as a species. A massive release of ocean floor methane could cause real runaway global warming that would have dramatic impact on life. But methane continually leaks from seabeds around the world, contributing to the total amount of carbon injected into the ecosystem. A new report finds that ocean methane concentrations have been underestimated by a factor of 10 to 20 fold.
International negotiators at a recent UN climate conference held in Bangkok repeated the demand that global warming this century be limited to no more than 2˚C. But while those attending the UN boondoggle stuck to the climate alarmist party line, results from a newly published Canadian government climate study concluded that “it is unlikely that warming can be limited to the 2˚C target.” The modeling based paper found that reaching the stated IPCC goal would require that greenhouse emissions “ramp down to zero immediately,” which means shutting down the global economy and banning the automobile. Moreover, starting in 2050 scientists would need to actively remove greenhouse gases from the atmosphere, requiring a rush to implement controversial and possibly dangerous geoengineering programs. Why does the global warming lobby continue demanding the impossible? Perhaps it is because global warming isn't about climate change at all.
It is well known that water, H2O, is the single most important greenhouse gas. But water also plays a central role in determining the delicate balance of energy and mass that regulates the temperature of Earth. A wide range of predictions have been made regarding water in a warming climate, ranging from catastrophic droughts to increased monsoon rains and tropical storms. Conventional wisdom states that a warmer world is a wetter world. In a newly published paper in the journal Science, two researchers examine the Eocene (∼56 to 34 million years ago), looking for clues to the tropical climate–water relationship. Annual global temperatures during the Early Eocene Climatic Optimum (EECO) around 50 million years ago were as much as 12°C higher than modern values. The new results provide compelling evidence that the tropical engine of the water cycle was more active than predicted by current climate models.
