One of the sad side effects of the global warming climate scam is the way otherwise fairly intelligent people have been snookered into believing the dumbest things. An example in point: in a world where millions die each year due to malnutrition, US Secretary John Kerry lectured African leaders attending a summit in Washington that creating more farms in Africa causes too much carbon pollution. Can you imagine the response of any national leader, being told he must let his people starve because a bunch of rich nation, ivory tower science boffins have this unproven, wild idea that CO2 might cause the world to warm by a degree or two a hundred years from now? This is the type of imbecility that comes from following a pernicious untruth down a rabbit hole of false assumptions. Yet around the globe people seem defenseless against the infectious ignorance that is climate alarmism.
News media around the world have been all abuzz, with headlines declaring “Irreversible collapse of Antarctic glaciers has begun” and “West Antarctic Ice Sheet collapse is under way.” The “rapid” collapse threatens to cause sea level change of 4 to 13 feet. Calamity will surely follow. “Collapse will change the coastline of the whole world” shrieked the UK's Guardian, always a good source for mindless rumor mongering. What they are referring to are a pair of new reports that say the West Antarctic Ice Sheet (WAIS) has pushed its way over a submerged ridge that had been impeding its forward progress, causing the ice sheet to become unstuck from the sea floor. The WAIS is now flowing more freely, and hence more rapidly, into the sea. What the alarmist headlines don't say is that any impacts from this change are centuries to millennia in the future.
The world is entering the 16th year of the greatest climate science embarrassment in modern history—the pause in global warming. Despite rising IPCC confidence levels and hundreds of computer model predictions, that darned old climate is just not behaving like the boffins say it should. After all, CO2 keeps rising, and we all know that CO2 drives Earth's climate like the thermostat in a house... or not. No longer able to sweep the lack of warming under the observational rug, the climate change community had started flailing about for answers: the heat must be hiding deep in the ocean, it must be soot from China, some have even begun to wonder whether there is something wrong with their models. Most are still convinced that the missing heat is hidden somewhere because they will not accept the simplest explanation—the theory of Anthropogenic Global Warming is fundamentally incorrect.
Nature has served up a lesson to publicity seeking, self important scientists during the past month. It seems that a clutch of global warming true believers chartered a ship to go visit Antarctica, in an effort to show that the southernmost continent is being ravaged by human caused climate change. This shipboard comedy of errors backfired on the warmists when their ship got stuck fast in the ice, kilometers from a bay they hoped to find ice free. Moreover, at least one other ship sent to rescue the hapless climatological tourists got stuck as well. All of this in the middle of the Antarctic summer. Will they never learn that making unfounded claims in an attempt to “prove” anthropogenic global warming inevitably fails? It would all be laughable if this floating farce wasn't going to cost the taxpayers of Australia, the US and other countries several million dollars to rescue the fools.
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.
For some reason a lot of people have become fixated on Antarctic ice—is it waxing or waning, accumulating or melting. Climate alarmists have striven mightily to show that ice at the poles in on the decline, melting in the face of rising global temperatures. Antarctica, with the largest store of glacial ice on the planet, is the primary focus of attention. If Antarctica’s ice sheets were to melt it would be a calamity for mankind. Unfortunately, Earth's climate system contains many cyclic trends, operating on decadal and longer periods of time. In the past, what some claim are clear trends have turned out to be only short term in nature. A new report, just published online, concludes that it is unclear if changes in atmospheric circulation over West Antarctica during the past few decades are part of a longer-term trend. In fact, ice cores reveal a significant increase in the oxygen isotopes from precipitation over the past 50 years, but the anomaly cannot be distinguished from natural climate variability.
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.
It's everywhere on Earth, on the other planets and moons of the solar system, and even in comets from deep space. It is the frozen form of water, commonly called ice. Something so ubiquitous and familiar, one would think that science knows a lot about ice. It turns out science knows less than we might suppose. In a commentary in the journal Nature, an ice scientist raises ten open questions about ice. For example, the article states: “We cannot predict with certainty when and where ice clouds will form in the atmosphere; areas of the sky remain humid when we would expect them to freeze.” Ice is a fundamental part of Earth's climate, yet these questions and others remain unanswered. How can climate science claim to predict the fate of the polar ice sheets or mountain glaciers when we do not really understand the substance that they are made of?
Just when it seems that public figures can sink no lower, be more cynical, act more duplicitous, a news story comes along that plumbs new depths in ideological betrayal. And so it was this week when the shocked staff at Current TV was called to an all hands staff meeting. They were informed that the Current TV network, supposedly a bulwark of liberal green thought holding back the barbarian hoards from FOX and talk radio, had been sold to those leading mideast liberals at Al Jazeera. Former Vice President and self styled eco-prophet Al Gore has made himself a much, much richer man by doing what the political class has done since the dawn of human history—sell out to the other side.
Something happened this year that has become rare in recent times, much of the United States has had a white Christmas. As of December 28th, 64.4% of the US was covered by snow with an average depth of 6.2 inches (15.7 cm). This compares with last month's coverage of only 19.8%. My own town of Conway, Arkansas, received 10 inches on Christmas day and a winter storm advisory is in effect as another storm makes its way eastward. For Arkansas, this has been the snowiest Christmas ever, breaking the old record set in 1926, and the 7th snowiest day overall since 1875. But North America is not alone in feeling winter's bite—record cold continues in Siberia, while a vicious cold snap across Russia and Eastern Europe has claimed nearly 200 lives. What does all this say about global warming?
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.
Over the past 50 years or so, the Antarctic Peninsula, the northernmost part of the mainland of Antarctica, has experienced rapid warming and the collapse of a number of ice shelves. A new temperature record derived from an ice core drilled on James Ross Island, has triggered a reassessment of what triggered the recent warming trends. This new core provides the best record of climate events on the peninsula going back at least 20,000 years, and may extend back as far as 50,000 years. From this new data a team of researchers has constructed the most detailed history of climate on the Antarctic Peninsula known to science and it has revealed a number of interesting things. Most important of these is the fact that this area undergoes bouts of rapid warming periodically and that things were at least as warm on the peninsula 2,000 years ago. So much for “unprecedented” warming on the Antarctic Peninsula.
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.
Another group of researchers has weighed in on the continuing scientific scuffle over whether the Himalayan glaciers are melting. A letter to Nature Geoscience reports that the Karakoram glaciers, a part of the greater Himalaya north of the actual Himalaya Range, are actually gaining mass. Outside the ice sheets in Greenland and Antarctica, the Karakoram is the most heavily glaciated part of the world, containing nearly 3% of the planet's total ice area. But because they are so large, difficult to get to and dangerous to travel on, they have not been measured by conventional survey methods. Scientists have instead, been relying on satellite measurements, whose accuracy is now called into question. This impressive new study says that the Karakoram glaciers are not only not shrinking, they are accumulating enough ice each year to cause a slight decrease in ocean sea-level.
The last interglacial period (LIG)—the Eemian—is commonly believed by scientists to have been warmer than the current Holocene interglacial. Along with that balmier climate there is evidence that sea levels were significantly higher than today. Previous studies have pegged Eemian sea levels at 4 to 6m higher than today. Recently, a new investigation raises that estimate, reporting that ancient sea levels peaked between 6.6 and 9.4 m (~20 to 30 feet). Modern day accounts of flooding in low lying coastal areas and tropical islands abound, with ominous suggestions of links to global warming. How high the oceans will rise is a topic of debate for IPCC members, the news media and assorted climate alarmists, but they are asking the wrong question. Instead, they should ask why are sea levels so low?
