Science is about simplicity. A well-accepted aphorism about science, in the context of difference of opinion between two points of view, is “Madam, you are entitled to your own interpretation, but not to your own facts”.
The world stoker of the fires of global warming alarmism, the United Nations Intergovernmental Panel on Climate Change (IPCC), cleverly suborns this dictum in two ways. First, the IPCC accepts advice from influential groups of scientists who treat the data that underpins their published climate interpretations (collected, of course, using public research funds) as their own private property, and refuse to release it to other scientists.
Thus, confronted in 1996 with a request that he provide a U.S. peer-review referee with a copy of the data that underpinned a research paper that he had submitted, U.K. Hadley Climate Research Centre scientist Tom Wigley responded: First, it is entirely unnecessary to have original “raw” data in order to review a scientific document. I know of no case at all in which such data were required by or provided to a referee. Second, while the data in question [model output from the U.K. Hadley Centre’s climate model] were generated using taxpayer money, this was U.K. taxpayer money. U.S. scientists therefore have no a priori right to such data. Furthermore, these data belong to individual scientists who produced them, not to the IPCC, and it is up to those scientists to decide who they give their data to.
In the face of such attitudes, which treat the established mores of scientific trust and method with contempt, it is scarcely surprising that it took Canadian statistics expert Steve McIntyre many years to get the primary data released that was used by another Hadley Centre scientist, Keith Briffa, in his published tree-ring reconstructions of past temperature from the Urals region, northern hemisphere. When he finally forced the release of the relevant data, McIntyre quickly proceeded to slay a second climate hockey-stick dragon which - like the first such beast fashioned by U.S. scientist Michael Mann, and widely promulgated by the IPCC - turned out to be based on faulty statistical methodology (see summary by Ross McKitrick here).
A variant on this, along “the dog ate my homework” path, also involves the Hadley Centre - which is the primary science provider of global temperature statistics to the IPCC. Faced with requests from outside scientists for the provision of the raw temperature data so that scientific audit checks could be undertaken, Hadley’s Phil Jones recently asserted that parts of the raw data used to reconstruct their global temperature curve for the period before about 1980 cannot be provided to outsiders because it has been lost or destroyed. In other words, it is now impossible to conduct an independent audit of the Hadley temperature curve for 1860-2008, on which the IPCC has based an important part of its alarmist global warming advice.
So much for data perversions. The second type of common distortion of normal scientific practice by the IPCC and its supporters concerns not data but hypotheses - which IPCC likes to define in its own way to suit its own ends. This attitude often manifests itself in the fashion expressed in a recent letter sent to me, viz:
Proponents of AGW claim that their theory is supported by peer reviewed literature whilst the case against it is not. This is a very effective argument and, although Solomon’s book The Deniers goes some way to counter it, I am not aware of an equally effective refutation. If there is one I would be most grateful if you could point me to it.
In an Australian variation of this, Greg Combet, assistant to climate Minister Penny Wong, earlier this year asserted with blatant inaccuracy that “we use only peer reviewed science and our opposition doesn’t”. Other IPCC sycophants phrase it slightly differently, such as: “if you climate sceptics had a scientific point of view it would have been published in reputable, peer-reviewed journals”.
Statements such as these all reflect a fundamental lack of understanding about the way that science works. They also exemplify the way in which climate alarmists always seek to frame the debate in ways that delivers them control, especially by clever choice of language (clean energy; climate change instead of global warming; carbon dioxide is a pollutant instead of a beneficial trace gas, etc.), or, in this case, by framing a hypothesis for testing that suits their political ends rather than Science’s ends.
If you accept at face value questions and comments like the ones enumerated above, you fall into a carefully laid climate alarmist trap. For the question “why are there no papers in peer-reviewed journals that disprove the hypothesis of dangerous human-caused global warming” is predicated, as is all related IPCC writing, on faulty science logic; specifically, it erects a wrong null hypothesis.
Scientists erect hypotheses to test based upon the fundamental science assumption of parsimony, or simplicity, sometimes grandly referred to as Occam’s Razor. That is to say, in seeking to explain matters of observation or experiment, a primary underlying principle is that the simplest explanation be sought; extraneous or complicating factors of interpretation, such as “extraterrestrials did it”, are only invoked when substantive evidence exists for such a complication.
Concerning the climate change that we observe around us today - which, importantly, is occurring at similar rates and magnitudes to that known to have occurred throughout the historical and geological past - the simplest (and therefore null) hypothesis, is that “the climate change observed today is natural unless and until evidence accrues otherwise”.
In regard to which, first, no such evidence has emerged. And, second, like any null hypothesis, that about modern climate change is there to be tested, as it has been. There are literally tens of thousands of peer-reviewed papers in major scientific journals that contain observations, data, experiments and theoretical reasoning that are consistent with the null hypothesis, which has therefore yet to be falsified (but, of course, one day might be).
The onus is therefore on Penny Wong and her scientists to provide some “evidence otherwise”. To give a clue how hard that task is, note that since 1988 (when the IPCC was created) western nations have spent more than $100 billion, and employed thousands of scientists, in attempts to measure the human signal in the global temperature record. The search has failed. Though no scientist doubts that humans influence climate at local level - causing both warmings (urban heat island effect) and coolings (land-use changes) - no definitive evidence has yet been discovered that a human influence is measurable, let alone dangerous, at global level. Rather, the human signal is lost in the noise of natural climate variation.
That the correct null hypothesis is the simplest hypothesis is, of course, no reason why other more complex hypotheses cannot be erected for testing. For instance, should you wish to test (as the IPCC should) the idea that “human carbon dioxide emissions are causing dangerous global warming”, then there are several ways that that can be done.
The result, long ago, has been the falsification of the dangerous human-caused warming hypothesis. Failed tests include: that global cooling has occurred since 1998 despite an increase in carbon dioxide of 5%; the lack of detailed correlation between the carbon dioxide and temperature records over the last 100 years; consideration of cause and effect timing of past carbon dioxide and temperature levels in ice core records; the absence of the model-predicted temperature hotspot high in the tropical troposphere; the low sensitivity of climate to carbon dioxide forcing as judged against empirical tests; and the demonstrable failure of computer GCMs to predict future climate.
These matters, and that the dangerous warming hypothesis fails numerous empirical tests, have been described in many places. Such writings, whether in refereed journals or not, are simply disparaged or ignored by those who wish to pursue the alarmist IPCC line.
It bears repeating that the onus is on Minister Wong, or her advisory IPCC scientists, to provide any evidence that the null hypothesis regarding modern climate change is false. Because she cannot do so, the clever trick is used of inverting the null hypothesis to demand that climate rationalist scientists demonstrate that human-cased global warming is not occurring.
Perhaps none of this would matter particularly were we dealing only with a squabble amongst scientists. But when ministers in our governments write, as did the Queensland Minister for Climate Change recently, that “The Queensland Government, along with the Australian Government and governments around the world, supports the findings of the IPCC”, it becomes a critical matter of necessity to understand that, in addition to being political in the first place, IPCC advice is also based upon faulty, indeed manipulative, science practice.
As independent scientific advisors to Senator Fielding have shown, the IPCC-derived science advice that the Australian Government is using as the basis for its carbon dioxide tax legislation is utterly flawed. This finding has yet to be rebutted.
Senators who vote for the second version of the misbegotten and misnamed Carbon Pollution Reduction Scheme bill will be supporting strongly harmful legislation that is based upon faulty science. Thereby, they will be abandoning their duty of care for the welfare of the Australian people.

That god among men and Nobel Peace Prize winner, Al Gore, told us in “An Inconvenient Truth”, his Oscar-winning documentary, that we had to brace for increasing numbers of hurricanes as the result of global warming.
So, where are the hurricanes of 2009, Mr. Gore?
The hurricane season that runs from June through October is about to end with nothing more than one weak to borderline moderate tropical storm that hit Florida’s panhandle, but there have been NO hurricanes.
So, where are the hurricanes of 2009, Mr. Gore?
Trying to predict how many hurricanes there will be each year is probably fun, but is a highly risky undertaking. I have a lot of friends among the meteorological and climatological community, men of science, but I always cross my fingers for them when they take a run at it.
This year, Bill Gray of Colorado State, perhaps the best known among the hurricane forecasters, thought there would be at least 7 hurricanes of which 3 would be major. Weather Services Inc. agreed with Dr. Gray and, over at Accuweather, the prediction was for 8 hurricanes of which 2 would be major.
NOAA and the National Weather Service do not predict hurricanes, but as political as well as scientific entities they have a very bad track record of trying to confirm Al Gore’s global warming claims.
In March, William J. Broad, reporting in The New York Times, noted that Gore’s “scientific audience is uneasy” in the wake of his global warming documentary. “These scientists argue that some of Mr. Gore’s central points are exaggerated and erroneous. They are alarmed, some say, at what they call his alarmism.”
In Great Britain, a judge ruled that the documentary could not be shown in the schools unless teachers read a long list of its erroneous claims.
Since an increase in hurricanes was one of his dramatic claims along with rising sea levels and disappearing polar bears, Gore is batting zero these days. The sea levels have been rising a few inches every century for millennia and it is generally conceded that the polar bear population since the 1950s has been thriving.
In May, hurricane specialist Chris Landsea of the National Hurricane Center in Miami disputed theories that “global warming” has caused more hurricanes. His study was published in The Journal of Climate.
Landsea, like all meteorologists who haven’t been in a coma since the 1980s, knows that the Earth has been in a cooling cycle since 1998. Thus, the warmth that feeds hurricanes has diminished and is likely to stay that way for decades to come.
Landsea’s research showed that, since the mid-1990s, the average number of hurricanes per year had almost doubled what it was during the few prior decades, about on par with hurricane activity in the early 20th century. “It’s busy, yes, but not anything we haven’t seen before,” said Landsea while attending the Florida Governor’s Hurricane Conference in May.
For the non-scientist, that should confirm that hurricanes are governed by natural cycles, not some non-existent, dramatic increase called “global warming.”
Though what I know about hurricanes would fit comfortably in a bug’s ear, I am nonetheless tempted to suggest that the cooling cycle the Earth entered in 1998 may be a contributing factor to why this year’s hurricane season is, at this writing, minus any hurricanes.
So, where are the hurricanes of 2009, Mr. Gore?
Known as “the Gore factor”, it is the irony of blizzards or severe snow storms that seem to follow him around whenever he delivered one of his “global warming” speeches.
It is my profound prayer that, in December when the United Nations climate conference convenes to issue an international treaty based on the Great Global Warming Lie, that the city of Copenhagen gets hit by a blizzard so great that the delegates cannot leave their plush hotels for days. See post here.
UPDATE: See Monckton’s defense of his sovereignty concerns in this video.
President Obama may be traveling again to the Danish capital in December to attend the U.N. COP15 Climate Change Conference. This agreement would commit the United States to punitive and expensive greenhouse gas regulations dictated by the United Nations without recourse.
COP stands for “Conference of the Parties” and the December Copenhagen conference will be the 15th under the United Nations Framework Convention on Climate Change (UNFCCC), hence COP15. According to their website, it will be one of the largest conferences ever held outside the New York or Geneva headquarters, with an anticipated attendance of over 10,000 people, including governmental representatives from 189 countries, industry groups, and other non-governmental organizations.
The theme of the December 7 - 18 conference is “Hope,” so perhaps Mr. Obama will have more luck this time. Instead of soliciting the International Olympic Committee with trite cliche and no payoffs, he will be doing something much easier: selling out our country. After all, ceding power, relinquishing billions in U.S. tax dollars and destroying U.S. economic competitiveness is a pretty easy sell to the countries that will benefit, and he has had a lot of practice doing the same thing here at home. He will have a hard time screwing this one up.
The Hope site optimistically pronounces: On 7 December, leaders from 192 countries gather for U.N. Climate Change Conference in Copenhagen and decide the fate of our planet…
Decide the fate of our planet… Do these people have any idea how mindlessly grandiose they sound? Of course not. They are out to save the planet, just like Nancy Pelosi! It is hard for a normal person to imagine making such proclamations without embarrassment. But this is today’s political class
This agreement will cede U.S. sovereignty permanently and irrevocably to the United Nations. So said British Lord Christopher Monckton at an event at Bethel University in St Paul, Minnesota this past Wednesday, October 14th.
Lord Monckton was former British Prime Minister Margaret Thatcher’s science advisor. He has lectured and written extensively on the issue, including an in-depth scientific critique to the 50,000 member American Physical Society, a serious side-by-side comparison slap-down of Al Gore’s global warming assertions, and a recent summary of the global warming issue. In introducing his topic at Bethel University, he states unequivocally:
...and I am going to show you the latest science, which now doesn’t leave the question unsettled any more, this is now settled science, it is now settled science that there is not a problem with our influence over the climate. The science is in, the truth is out, and the scare is over.
You can watch his entire 1 hour 35 minute presentation here - well worth the time if you can spare it. The slideshow he frequently points to in this presentation can be viewed along with the video, here. Lord Monckton presents a series of statistics, charts and studies making a compelling case that not only is global warming insignificant - if it exists at all - but is likely not manmade, and more importantly, that the global warming alarmists have repeatedly, blatantly, deliberately lied, suppressing the facts to promote the myth.
Despite his effective refutation of manmade global warming, his closing remarks about the Copenhagen treaty are chilling:
I read that treaty. And what it says is this, that a world government is going to be created. The word “government” actually appears as the first of three purposes of the new entity. The second purpose is the transfer of wealth from the countries of the West to third world countries, in satisfication of what is called, coyly, “climate debt” because we’ve been burning CO2 and they haven’t. We’ve been screwing up the climate and they haven’t. And the third purpose of this new entity, this government, is enforcement.
So, thank you, America. You were the beacon of freedom to the world. It is a privilege merely to stand on this soil of freedom while it is still free. But, in the next few weeks, unless you stop it, your president will sign your freedom, your democracy, and your humanity away forever. And neither you nor any subsequent government you may elect will have any power whatsoever to take it back. That is how serious it is. I’ve read the treaty. I’ve seen this stuff about [world] government and climate debt and enforcement. They are going to do this to you whether you like it or not.
Note to be ratified and supercede our constitution, such a treaty would have to receive the support of 2/3rds of the senate. This is unlikely as they would be ceding their control as well as the executive branch to the UN. A very scary scenario and one which I would imagine many senators would have second thoughts about. I could imagine Obama signing it in Copenhagen as a gesture of support knowing it is likely too fail similar to Clinton and Kyoto.
A tiny little bug about the size of a grain of rice has become a focal point in the debate about manmade climate change. Over the last 12 years, the mountain pine beetle has spread quickly through the Mountain West and Canada killing millions of acres of pine trees.
The beetle thrives when conditions are drier and warmer than average and some experts have blamed its spread on manmade climate change and a warming environment. From Canada south to Colorado, images of acres of dead, brown trees amongst their healthy neighbors make for a stark picture of what may be forests in decline.
Global warming activists have been quick to seize on the pine beetle ‘epidemic’ as a sign of things to come and an impending ecological disaster. In truth, drawing the line between manmade climate change and the pine beetle outbreak is a stretch that few experts make. Rather, most see the outbreak as a natural function of forests and in many ways it is Mother Nature correcting man’s previous mistakes.
Colorado finds itself front and center in the battle against the mountain pine beetle. In the coming weeks the state’s forest service will be releasing its annual report and is expected to estimate that 2.5 million acres have been infected by the beetles since 1996 - the largest outbreak in state history. However, that represents a fraction of the state’s forest land and areas are being naturally rehabilitated after the infections pass.
The state’s forest service is reluctant to connect manmade climate change with the outbreak and studies have shown that while the outbreak is large, it is not entirely unprecedented. Sky Stephens, Forest Entomologist for the Colorado State Forest Service, says that while climate change is a hot topic, there “hasn’t been a well structured argument” connecting the two. Indeed, the state points to what it calls a ‘perfect storm’ of drought, recent warmer winters and forests that are denser than what nature intended. Any one of those factors could lead to an increase in beetle populations but coupled together, it becomes a difficult situation for foresters to manage.
Man may indeed have played a large role in the spread of the mountain pine beetle but not in the way climate change activists portray. For the latter half of the 20th century as people settled in forested areas in greater numbers, forest fires drew more attention. While in centuries past fires burned unabated as part of a natural cycle of the earth, man now was coming to the “rescue” and putting out the fires. In doing so, an unintended consequence of forest overgrowth was realized. By eliminating the natural death and re-birth cycle that fire brings, forests became more dense and just as critically, they have matured to an age that is ripe for pine beetles to attack.
Stephens said that our desire to stamp out fires in unpopulated areas did more harm than good. “It set us up for a number events that have and are going to happen,” she said. Stephens said the forests were never meant to have the dense stands that we have grown accustomed to seeing and the more food there is for the beetles, the greater the impact when they attack.
Dave Thom, a natural resources officer with the Black Hills National Forest agrees with Stephens. Of trying to point the finger at manmade climate change, he told the Rapid City Journal last month, “It’s more complicated than that.” The drought and the dense forests play a big factor according to Thom. He said, “As the trees get more dense, they are less able to resist bark-beetle infestations. When you take increasingly dense trees and add the drought, the intersection causes weakened trees that are more susceptible to beetle attack. That phenomenon can happen regardless of a few degrees of change in climate, measured on a global scale.”
Researchers point to outbreaks in the past that killed millions of lodgepole pines, before global temperatures rises are thought to be having an effect. The Rocky Mountains suffered through outbreaks in the 1960s, the 1970s and the early 1980s. A different beetle, the spruce beetle, is known to have caused extensive damage in western Colorado in the 1940s.
Before outbreaks were documented, tree-ring evidence points to extensive outbreaks before the 20th century as well. As the CFRI study said, “Insect outbreaks are a natural occurrence in almost all of the different kinds of forests in Colorado. Outbreaks do not occur very frequently; the time interval between successive outbreaks in any given area is usually measured in decades. Nevertheless, outbreaks can be expected periodically in almost any place in the state where forests are found.”
A recent study completed by the Colorado Forest Restoration Institute (CFRI) in conjunction with the Colorado State Forest Service and area universities flatly stated that the current outbreak is not unusual. “There is no evidence to support the idea that current levels of bark beetle or defoliator activity in Colorado’s lodgepole pine and spruce-fir forests are unnaturally high,” the study said. CFRI as well pointed to the age of the current forest as a factor in the outbreak. “Widespread burning in the late 1800s that resulted in extensive cohorts of relatively similar age that now are entering a stage that is susceptible to bark beetle outbreaks,” the study said.
The ravages of the mountain pine beetle are evidenced by anyone that travels in the Rocky Mountains. The damage occurs over a short period of time and can encompass large areas thus making the outbreaks seem unusual. However, the reality appears to be that the pine beetle, much like fire, is simply a natural process forests go through. And while the current outbreak is larger than we remember, Stephens summed it up by saying, “The beetles haven’t read the textbooks.” See full story here.
This “stunning” development (link to au.com story here) citing lake sediment and some midges “proves” everything. Glad that’s settled. See thoughts at the end. But here is the University of Colorado press release that started it all. Note that in no place in the release do they use the word “proof”.
Arctic Lake Sediment Record Shows Warming, Unique Ecological Changes in Recent Decades - October 19, 2009
An analysis of sediment cores indicates that biological and chemical changes occurring at a remote Arctic lake are unprecedented over the past 200,000 years and likely are the result of human-caused climate change, according to a new study led by the University of Colorado at Boulder. A University of Colorado at Boulder-led analysis of a 200,000 year-old sediment core from a Baffin Island lake indicates warming temperatures in the Arctic due to human activity are overriding a natural cooling trend in the region.

While environmental changes at the lake over the past millennia have been shown to be tightly linked with natural causes of climate change - like periodic, well-understood wobbles in Earth’s orbit - changes seen in the sediment cores since about 1950 indicate expected climate cooling is being overridden by human activity like greenhouse gas emissions. The research team reconstructed past climate and environmental changes at the lake on Baffin Island using indicators that included algae, fossil insects and geochemistry preserved in sediment cores that extend back 200,000 years.
“The past few decades have been unique in the past 200,000 years in terms of the changes we see in the biology and chemistry recorded in the cores,” said lead study author Yarrow Axford of CU-Boulder’s Institute of Arctic and Alpine Research. “We see clear evidence for warming in one of the most remote places on Earth at a time when the Arctic should be cooling because of natural processes.”
The study was published Oct. 19 in the Proceedings of the National Academy of Sciences. The study included researchers from CU-Boulder, the State University of New York’s University at Buffalo, the University of Alberta, the University of Massachusetts and Queen’s University in Kingston, Ontario. The sediment cores were extracted from the bottom of a roughly 100-acre, 30-foot-deep lake near the village of Clyde River on the east coast of Baffin Island, which is several hundred miles west of Greenland. The lake sediment cores go back in time 80,000 years beyond the oldest reliable ice cores from Greenland and capture the environmental conditions of two previous ice ages and three interglacial periods.
The sediment cores showed that several types of mosquito-like midges that flourish in very cold climates have been abundant at the lake for the past several thousand years. But the cold-adapted midge species abruptly began declining in about 1950, matching their lowest abundances of the last 200,000 years. Two of the midge species adapted to the coldest temperatures have completely disappeared from the lake region, said Axford. In addition, a species of diatom, a lake algae that was relatively rare at the site before the 20th century, has undergone unprecedented increases in recent decades, possibly in response to declining ice cover on the Baffin Island lake.
“Our results show that the human footprint is overpowering long-standing natural processes even in remote Arctic regions,” said co-author John Smol of Queen’s University. “This historical record shows that we are dramatically affecting the ecosystems on which we depend.” The ancient lake sediment cores are the oldest ever recovered from glaciated parts of Canada or Greenland. Massive ice sheets during ice ages generally scour the underlying bedrock and remove previous sediments. “What is unique about these sediment cores is that even though glaciers covered this lake, for various reasons they did not erode it,” said study co-author Jason Briner of the University at Buffalo. The result is that we have a really long sequence of sediment that has survived Arctic glaciations.”
Axford emphasized the multiyear research project required expertise from each of the five institutions involved in the PNAS study. “This was a team effort all the way around, and each of the institutions has a unique set of skills that allowed us to carry out this study,” she said. “We needed people who understood algae, insects, glaciers and geochemistry, not to mention how to drive snowmobiles and extract the cores.” The study was funded by the National Science Foundation, the Natural Sciences and Engineering Research Council of Canada and the Geological Society of America.
A study published in Science magazine last month that involved CU-Boulder researchers and reconstructed past temperatures in the Arctic using ice cores, tree rings and lake sediments concluded that recent warming around the Arctic is overriding a cooling trend caused by Earth’s periodic wobble. Earth is now about 0.6 million miles further from the sun during the Northern Hemisphere summer solstice than it was in 1 B.C. - a trend that has caused overall cooling in the Arctic until recently. INSTAAR researcher and CU-Boulder geological sciences Professor Gifford Miller was a co-author on both the PNAS study and the recent Science study.
-------------------------------
A scientist on a mailing list I subscribe to put it in perspective this way:
1. “Several types of mosquito-like midges that for many thousands of years thrived in cold climate surrounding the lake suddenly began declining at around 1950” - Have they accounted for the use of DDT, then? Seems to me that DDT on Baffin Island could have been very popular among trappers and the military in the 50s. Possibly pertinent too: DDT and its breakdown products are transported from warmer regions of the world to the Arctic by the phenomenon of global distillation, where they then accumulate in the region’s food web. Thus there might be a human impact on this parameter, but of another kind.
Beyond that, though, if the authors are suggesting that CO2 has caused a mosquito or midge shortage up north, they should consult caribou herds, whose route of wandering is traceable to wind direction, so desperate are these animals to escape the floating bloodsuckers. In the Canadian Arctic, researchers who bared their arms, legs, and torsos in an experiment reported as many as 9,000 [mosquito] bites per minute. Who knows, then? Changing wind patterns and a consequent shift of caribou migration (the supporting host) or DDT usage might account for the decline of midge bodies in this particular study of Ayr Lake. But CO2?
2. “The Earth is now some 600,000 miles (966,000 kilometers) further from the sun during the Northern Hemisphere summer solstice than it was at the time of Jesus Christ” - A sad example of allegation that’s already become a repeated “fact” simply because no one’s bothered to investigate it. I have, and find no indication that this million km claim is true. - Alan

Just a note on DDT from Wikipedia: “First synthesized in 1874, DDT’s insecticidal properties were not discovered until 1939. In the second half of World War II, it was used with great effect to control mosquitoes spreading malaria and lice transmitting typhus among civilians and troops, resulting in dramatic reductions in the incidence of both diseases. The Swiss chemist Paul Hermann Muller was awarded the Nobel Prize in Physiology or Medicine in 1948 “for his discovery of the high efficiency of DDT as a contact poison against several arthropods.” After the war, DDT was made available for use as an agricultural insecticide, and soon its production and use skyrocketed.
Here’s a 2008 study on DDT in penguins that sums it up pretty well: POPs (Persistent organic pollutants) accumulate in the Antarctic and Arctic via repeated cycles of evaporation and condensation as they move poleward through the atmosphere from the tropical and temperate zones where most are released.
2005 TORONTO (CP) - Seabird droppings are leaving more than a foul mess in the Arctic they’re contaminating northern lakes and ponds with extremely high levels of mercury and DDT, Canadian researchers have found. Concentrations of the chemicals were found to be as much as 60 times higher in bodies of water on Devon Island, Nunavut, than in other Arctic areas, says a study to be published Friday in the journal Science.
No, no it couldn’t be DDT killing those midges, it has to be global warming since 1950.
Journalism is dead, science may not be far behind.
