A pair of researchers has published a new report in the Proceedings of the National Academy of Sciences (PNAS) in which two out of three glaciers studied were disappearing. In a report that was edited by James Hansen, of the Goddard Institute for Space Studies, it would appear that the glaciers of the Himalaya are melting rapidly, but that is not how the report ends. The authors state that poor selection of study sites have led to the widespread use of non-representative data. Moreover, the IPCC report and others overstate the disappearance of Himalayan glaciers.
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.
Climate alarmists have been pointing to the output of computer models for decades, insisting that the models could predict the future. The Earth is warming uncontrollably, they claim, and human CO2 emissions are the proximate cause. Others have argued that CO2 is not a powerful enough forcing factor to cause such a calamity. Still, the climate change catastrophists point to their models, claiming that the models do not lie. Now, according to data released by NASA, it seems that climate models not only can not predict the future, they do not even echo current conditions correctly. A new paper says climate scientists have misdiagnosed the surface temperature feedbacks and more heat is being radiated back into space than the models allow for. We have all been subjected to three decades of climate change malpractice.
North America, after suffering through a lingering cold, wet spring, is now experiencing a bout of record setting summer heat. Once again, the sizzling summer temperatures are being blamed on global warming. The prophets of climate catastrophe claim to be exposing mankind's folly by shining the light of science on humanity's sins against nature. Perhaps it is time to recall the words of Thomas Hobbs who described the Kingdom of Darkness as “nothing else but a confederacy of deceivers that, to obtain dominion over men in this present world, endeavour, by dark and erroneous doctrines, to extinguish in them the light.” With sweltering weather as their cover, minions of the ecological Kingdom of Darkness are again on the march.
Maize, called corn in the US, is one of the world's great staple crops. It is consumed directly, fed to food animals, and processed into oil and sweeteners. The US is the largest consumer and producer of corn, growing more than twice as much as next largest producer China. A rise in corn prices causes a rise in food prices in general, and shortages have even caused riots in some countries. As important as corn is to the world's food supply it would seem the height of insanity to convert corn into automotive fuel. Yet last year, for the first time, more of the US corn crop went into the manufacture of ethanol fuel than for livestock feed, corn's traditional main use. About 40% of US corn now goes to ethanol, and though there is serious talk about dropping the $0.45 per gallon government subsidy, ethanol producers remain sanguine about their future. Why? Because the federal government will still mandate the mixing of ethanol with gasoline even if it no longer subsidizes its use directly.
Most people fall into one of two categories when it comes to predictions of future climate calamities: they either do not realize that the predictions are predicated on computer models or they unquestionably trust the models to reveal the future. A clear and lucid online article in Nature Geoscience addresses the current state and limitations of climate modeling. The article points out that State-of-the-art climate models are largely untested against actual occurrences of abrupt change. “It is a huge leap of faith to assume that simulations of the coming century with these models will provide reliable warning of sudden, catastrophic events,” the author states. To counter claims of predicted “tipping points,” incidents of abrupt climate change from the past are examined—incidents that current models get wrong.
In the debate over climate change one of the most misunderstood and misused terms is sensitivity. Climate sensitivity is usually defined as the change in global mean surface temperature following a doubling of atmospheric CO2 once equilibrium is reached. The concept seems simple but there is a catch: the definition of 'equilibrium', which depends on the timescale employed. As it turns out, the timescales that nature uses—which can encompass thousands and even millions of years—cannot be compared with the century long timescale used in climate models. A recent online article, published by Nature Geoscience, states that accurate prediction of Earth's future warming hinges on our understanding of climate sensitivity. Moreover, only by studying climate change in the past, the paleoclimate, identifying all the factors involved and how they interacted can our understanding of climate sensitivity be improved.
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?
Recent announcements about failing green companies have mostly flown under the major media radar. After all, when President Obama hops in Air Force One for a quick trip to a green business to make a speech about his administration's nonexistent energy policy that's worth covering—when that green business shutters its doors (after absconding with millions in tax credits) that's embarrassing, to green cheerleaders and the liberal media in general. Sadly, failure to revive the economy not withstanding, many actually believe that, if only we could provide more billions in subsidies, good green jobs would spring up like weeds. The reality is that green business cannot exists without government largess and that green economy we have heard so much about was stillborn—killed in its government funded womb by economic reality.
The glaciers of Alaska and northwestern Canada are a major contributor of fresh water to the world's oceans. They have long been considered important contributors to global sea level, but their remoteness has complicated efforts to measure changes in ice mass. As described in a new perspective article, published in the May 27 issue of Science, satellite measurements of Earth's gravitational field and improved on-site measurements have been used to generate global maps of water-mass variation, confirming the large role Alaska glaciers play in global sea-level regulation. Climate change advocates would claim that global warming will melt Alaska's glaciers, flooding low lying countries, but determining the rate at which the glaciers are melting is not a simple thing. Far from solving the puzzle, the new observations are revealing unexpected complexities in the magnitude and rate at which Alaska glaciers respond to climate.
Recently, the 3rd Nobel Laureate Symposium decided to hold a trial, charging humanity with ruining the planet. Based on the so called 9 Planetary Boundaries, a jury of 20 Nobel Laureates sat in judgment while “compelling evidence” was presented showing that “humanity may now be capable of radically altering the remarkable conditions for life on Earth.” The Planetary Boundaries approach was developed by 28 scientists, who estimated that three of the boundaries, climate change, the nitrogen cycle and biodiversity loss, have already been crossed and that several others are all ready in dangerous territory. We have all been charged with transgressing boundaries laid down by a group of scientists most people have never heard of, judged and found guilty by a gaggle of Nobel Prize winners, and been remanded to the UN for punishment. This sham trial does not represent justice but an attempt to place humanity in ecological bondage.
Despite warnings to the contrary, and waning public support, the all purpose boogieman climate change is once again getting credit for the recent spate of natural disasters in the US. Whether its flooding on the Mississippi, rain soaked fields too wet to plant, or rampaging tornadoes laying waste to whole towns the villain behind our misfortune is anthropogenic global warming. Reports from the scenes of devastation are sure to include at least one reference to climate change, which is of course caused by people. In essence, the yammering news media—who always needs a culprit to blame when disaster befalls a group of innocents—has placed the blame squarely back on humanity. That's right, we are responsible for the tragic deaths of hundreds of people caused by storm, flood and tornadoes. The chattering class once again demonstrates that they have bought the IPCC climate change scam: hook, line and sinker. They would rather mindlessly repeat the discredited memes of climate alarmists than think critically themselves.
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.
