The NRDC's Non-Lethal Methods to Prevent Conflicts Between Predators and Livestock


Every year, the U.S. Department of Agriculture's Wildlife Services program kills thousands of predators as a taxpayer-funded subsidy to the livestock industry, using controversial and inhumane methods such as poisons and aerial gunning. Wildlife Services largely ignores the many non-lethal ways to prevent conflicts between predators and livestock. In fact, a small, but growing number of ranchers are turning away from Wildlife Services’ “sledgehammer” approach and emphasizing non-lethal conflict-prevention techniques because they recognize that predators are an integral part of the landscapes where they ranch.

Wildlife Services needs to end the use of inhumane, hazardous, and environmentally harmful poisons—specifically, Compound 1080 and sodium cyanide—to kill predators. Instead, the agency should employ non-lethal conflict prevention methods. Specifically, Wildlife Services, and the private parties it assists, should be required to use, or attempt to use, nonlethal deterrence methods before resorting to lethal control.

Should the Wolf continue to be protected?

From: VIRGINIA MORELL, SCIENCE
Published February 9, 2014 08:03 AM




The ongoing battle over a proposal to lift U.S. government protections for the gray wolf (Canis lupus) across the lower 48 states isn’t likely to end quickly. An independent, peer-review panel yesterday gave a thumbs-down to the U.S. Fish and Wildlife Service's (USFWS's) plan to de-list the wolf. Although not required to reach a consensus, the four researchers on the panel were unanimous in their opinion that the proposal "does not currently represent the 'best available science'"

"It's stunning to see a pronouncement like this--that the proposal is not scientifically sound," says Michael Nelson, an ecologist at Oregon State University in Corvallis, who was not one of the reviewers. Many commentators regard it as a major set-back for the U.S. Fish and Wildlife Service (FWS), which stumbled last year in a previous attempt to get the science behind its proposal reviewed.
The USFWS first released its plan for removing the gray wolf from the endangered species list in June 2013. The plan also called for adding the Mexican gray wolf, a subspecies that inhabits the southwest, to the protected list. At the time, there were approximately 6,000 wolves in some Western and upper Midwestern States; federal protections were removed from the gray wolf in six of those states in 2011. More than one million people have commented on the plan. But regulations also require that the agency invite researchers outside of the agency to assess the proposal's scientific merit.
At its core, the USFWS proposal relies on a monograph written by its own scientists. They asserted that a different (and controversial) species, the eastern wolf (Canis lupus lycaon) and not the gray wolf, had inhabited the Midwest and Northeast. If correct, then the agency would not need to restore the gray wolf population in 22 eastern states, where gray wolves are no longer found.
But the four reviewers, which included specialists on wolf genetics, disagreed with the USFWS's idea of a separate eastern wolf, stating that the notion "was not universally accepted and that the issue was 'not settled'"—an opinion shared by other researchers.  "The designation of an 'eastern wolf' is not well-supported," says Carlos Carroll, a conservation biologist at the Klamath Center for Conservation Research in Orleans, California, who was not a member of the review panel.

The Reintroduction of Wolves Into Yellowstone

.

Nearly 1,650 wolves roam the Northern Rockies, in 250 packs with more than 110 breeding pairs. About 500 call Greater Yellowstone home and an estimated 80 wolves live within Yellowstone National Park.

GYC continues to monitor wolf numbers in Greater Yellowstone. Meanwhile, Yellowstone wolves are still playing their ecological role.

report from Oregon State University plant researchers William J. Ripple and Bob Beschta reinforces the belief that the wolf has been the primary factor in the improved health of aspen, willow, and cottonwood trees in Yellowstone National Park's Northern Range. This in turn has benefitted such Yellowstone wildlife as beaver, bison, pronghorn, songbirds, raptors, and trout.

The return of the wolf has changed elk behavior and reduced some herds, but overall numbers remain strong in Idaho, Montana and Wyoming. According to Yellowstone biologist Doug Smith, the Yellowstone herds remain healthy despite its smaller size. The number is more in line with historic levels since wolves were reintroduced and grizzly bears and mountain lions returned naturally. Overall elk populations in the states of Idaho, Montana, and Wyoming remain healthy. However, elk populations are now more dynamic with the return of large carnivores and elk distribution has shifted to areas of refugia which make them more difficult to hunt.  Elk populations are affected by many variables including weather, disease, predation, and human mortality.

The Greater Yellowstone Coalition has consistently worked to find the middle ground on wolf management, to move beyond the ongoing conflicts. They continue to promote science-based management and increased tolerance for this iconic animal in the Greater Yellowstone Ecosystem.

Wolves in Yellowstone prove one species' effect on ecosystem sustainability

 By Reno Berkeley
Sustainability. For conservationists, it’s one of the single most important issues facing our planet today. For others, it’s an inconvenient issue serving as a thorn in their side that prevents industrial and agricultural progress. The issue is very real, however, and even the smallest change in any given ecosystem can wreak havoc on the life that depends upon it.

Take the wolf, for example. While cattle ranchers and farmers don’t think anything of killing them for destroying their livestock (which is actually detrimental to our natural environment), the fact is, these animals are imperative for a healthy natural environment.Sustainable Man illustrates this point quite well in his video regarding how reintroducing wolves into Yellowstone National Park changed the ecosystem for the better. In 1995, the National Park Service reintroduced the gray wolf into the Lamar Valley of Yellowstone after the animals had largely been absent since about 1926. According to the NPS, the last wolf pack was killed in the park, but individual wolves were sometimes spotted.
Almost immediately, the small wolf packs began to make a difference. Prior to reintroduction, the deer population was out of control. Not even human efforts could curb the growth. As a result of this, vegetation began to decline due to overgrazing. After the wolf made its majestic reappearance in the park, the deer population fell, becoming more sustainable. The remaining herds learned to avoid certain places, like gorges, valleys, and anyplace they could easily be cornered.
Vegetation boomed, and because of this the rivers began to change. As George Monbiot explains in the video, the wolf’s presence had a positive domino effect: Because deer weren’t overgrazing and even avoiding places, all manner of vegetation made a comeback. Because the vegetation regenerated, the rivers through the park experienced less erosion. The rivers, which had previous Because of this rapid regrowth, birds and beavers returned. And beavers, as Monbiot states, helped create environments for other species, like otters and ducks. And the river became different. It slowed down in places, creating pools.
All this new life, all this new regeneration, because one predatory species was given a new chance in a place it had once called home for thousands of years. Because of federal government’s protection, the wolf population has grown to such an extent that they have been removed from the endangered species list. But the fight is not yet over.
Only the Mexican gray wolf remains federally protected, but even this species has its opponents. In New Mexico, one wolf is being removed from the wild due to a recent cattle-killing spree. Area ranchers aren’t happy and want the wolves gone. In California, the wolf may be removed from the protected list there.
In 2008, then-Alaskan governor Sarah Palin allowed the issuance of aerial hunting licenses so hunters could kill wolves. Her reason? To increase the caribou and moose population so humans could hunt and kill them for their dinner. It was not due to any real conservation efforts; it was for selfish purposes.
Obviously, wolves that prey on domesticated animals or those that hunt in areas humans frequent need to be controlled and removed. In the lower 48 states, the US Fish and Wildlife Service has suspended its plan to allow the killing of gray wolves pending further investigation. After learning more about how this species keeps its ecosystem in balance, I believe any plans to allow non-essential killing would be a bad idea.

Dispelling the Myths About Wolves



So why is the reintroduction of the gray wolf back in to areas that was once their normal range been such a divisive issue? Much of it has to do with myths, misinformation, unfounded fears and plain old misguided emotions. Throw in a substantial dose of political backscratching and couple that with state conservation agencies that are, in effect state game managers beholding to those who fund their existence - namely the hunting population. Now add to the mix a serious lack of understanding regarding the critical role that an apex predator plays in their relation to healthy ecosystem and you've developed a recipe for less than efficient wolf management.

Hunters, Politicians and Game Commissions

First, understand that I am not anti-hunting nor am I a preservationist. I am a conservationist - meaning I focus on the wise use of our natural resources. As some one who, by profession is engaged in wildlife management, it is important to know that I see sport hunting as a tool to support science based decisions. It should always be the means to an end . . . never as the end itself.

It is often said that hunters are the foremost champions of conservation. That may be true for some, but in my experience, it is not necessarily an accurate title to be bestowed upon the majority. The reasons that individuals hunt are as varied as they game the seek; however I dare say, conservation in the purest form would rank somewhere close to the bottom of the list. Admittedly, the dollars hunters pay in licensing fees, equipment purchase taxes, violation fines etc do go to support state conservation agencies. Unfortunately, today wildlife management in many states is not conservation as a scientific discipline. More often than not, state wildlife agencies are simply game managers - charged with ensuring that an adequate numbers of targets are available for the next season. Know that in no way do I mean to disparage the fine men and women who serve as game wardens, conservation officers, biologists and field technicians who dutifully serve to protect and manage wildlife. My issue is with the commissions that are owned by local, power hungry, vote thirsty politicians who dictate policy without the education or background to make the necessary decisions which would benefit the ecosystem. It is simply the corrupt tradition of "follow the money". 

Not the wolve's historic range?

I've heard and read many instances of people who have "verifiable proof" that many areas in US (including the Greater Yellowstone Ecosystem) was never the range for the gray wolf. This is pure fallacy. The historic range of the gray wolf covered nearly two-thirds of the United States.



The reintroduction of the gray wolf back into what was once their historic range was a monumental effort to right a terrible wrong - The decline of North American wolf populations coincided with increasing human populations and the expansion of agriculture. In the 1800's, westward expansion brought settlers and their livestock into direct contact with native predator and prey species. Much of the wolves' prey base was destroyed as agriculture flourished. With the prey base removed, wolves began to prey on domestic stock, which resulted in humans eliminating wolves from most of their historical range. Predator control, including poisoning, was practiced here in the late 1800s and early 1900s. Other predators such as bears, cougars, and coyotes were also killed to protect livestock and "more desirable" wildlife species, such as deer and elk.

By the start of the 20th century, wolves had almost disappeared from the eastern USA, excepting some areas of the Appalachians and the north western Great Lakes Region. The gray wolf's decline in the prairies began with the extermination of the American bison and other ungulates in the 1860s–70s. From 1900–1930, the gray wolf was virtually eliminated from the western USA and adjoining parts of Canada, due to intensive predator control programs aimed at eradicating the species. The gray wolf was exterminated by federal and state governments from all of the USA by 1960, except in Alaska and northern Minnesota. Thousands of wolves were killed from the early 1950s to the early 1960s, mostly due to poisoning.

Officially, 1926 was the year that the last wolves were killed within Yellowstone’s boundaries. When the wolves were eradicated and hunting eliminated, the elk population boomed. Over the succeeding decades, elk populations grew so large that they unbalanced the local ecosystem. The number of elk and other large prey animals increased to the point that they gathered in large herds along valley bottoms and meadows overgrazing new-growth vegetation. Because of overgrazing, deciduous woody plant species such as upland aspen and riparian cottonwood became seriously diminished. So, because the keystone predators, the wolves, had been removed from the Yellowstone-Idaho ecosystem, the ecosystem changed. This change affected other species as well. Coyotes filled in the niche left by wolves, but couldn't control the large ungulate populations. Booming coyote numbers, furthermore, also had a negative effect on other species, particularly the red fox, pronghorn, and domestic sheep. Ranchers, though, remained steadfastly opposed to reintroducing a species of animal that they considered to be analogous to a plague, citing the hardships that would ensue with the potential loss of stock caused by wolves.

In the 1960's and 70's national awareness of environmental issues and consequences led to the passage of many laws designed to correct the mistakes of the past and help prevent similar mistakes in the future. One such law was the Endangered Species Act, passed in 1973. 

The US Fish and Wildlife Service is required by this law to restore endangered species that have been eliminated, if possible. By 1978, all wolf subspecies were on the federal list of endangered species for the lower 48 states except Minnesota.


In 1991, Congress provided funds to the US Fish and Wildlife Service to prepare, in consultation with the National Park Service and the US Forest Service, an environmental impact statement (EIS) on restoration of wolves. In June 1994 the Secretary of the Interior signed the Record of Decision for the final EIS for reintroduction of gray wolves to Yellowstone National Park and central Idaho.
Staff from the National Park Service, the US Fish and Wildlife Service, and participating states prepared for wolf restoration to Yellowstone and central Idaho. The US Fish and Wildlife Service prepared special regulations outlining how wolves would be managed as an experimental population and Grey wolf packs were reintroduced to Yellowstone National Park and Idaho starting in 1995.


MYTH: Wolves cause significant losses to livestock producers * 

Averaged percentage of total sheep loss in Wyoming to various predators between 2000-2005. Wolves are responsible for less than 1% of losses
A common belief is that attacks on livestock by wolves is a significant, or even one of the primary causes that account for losses incurred by livestock producers.
In the US emphasis is placed primarily on the financial side, and also often emphasizes that the inclusion of the wolf within the Endangered Species Act violates "property rights" and "constitutional freedoms". The "emotional trauma" suffered by livestock producers as a result of predation is also frequently mentioned.
"It may destroy our livelihood, and our entire
lifestyle is also in jeopardy."
"A person doesn’t know or realize the emotional stress and fears of those that have had animals killed or maimed by wolves until you have it happen to yourself"
Though ranchers and farmers are always ready to give the numbers of livestock affected by predation, these are never given as percentages, or even stated in relation to total herd numbers. In most states the losses of livestock due to wolf predation was less than 1%. In the state of Wyoming, which lies entirely within the Yellowstone re-introduction area the number varied depending on year between 0.9% and 2% in the period 2000-2005, averaging under 1% over the period. This compares with 33.7% to 48.3% over the same period for losses due to coyotes, 4.1% to 10.9% due to eagles, and from 11.2% to 20.7% due to weather. Indeed, poison, often left by livestock producers to kill wolves and other predators, was often responsible for a greater proportion of losses than those due to wolf predation.
Emotional trauma is of course impossible to either prove or disprove, but it is important to remember that livestock is ultimately reared for slaughter, either to directly obtain the primary products (meat and hides) or as means of profitably disposing of "spent" dairy or wool herds/flocks. Thus one would expect anyone working in the livestock industry to deal with the death and processing of animals into food and other end-products as part of the day to day running of their business. It is highly unlikely that any individual emotionally disturbed by the slaughter of animals for meat or other products would find livestock work tolerable as a long time career.
The inclusion of wolves in the ESA provides a mechanism for financial compensation to be paid for damages caused by wolves in partnership with the Wolf Compensation Trust, and in the case of wolves found in the act of attacking livestock or other domesticated animals within private property, it is permissible for the owner to take measures necessary to protect them. Therefore it is hard to see how such an act can be a "violation" of rights.

Adult wolves kill each other in territory disputes. Such disputes happen each year, but increase when food is less abundant. This may have been why so many adult wolves died in fights during 2008. That year, scientists also found two wolves whose deaths were partially due to starvation.

MYTH: Wolves decimate game herds

"All wolves must be eliminated to restore our big game herds."
"The Canadian wolves have decimated our elk, mule
deer and moose populations to lows not seen since the ’60s."
There has been considerable misinformation over the impact of wolf populations on herds of elk. However the National Park Service studies indicate that wolf reintroduction to the park, a major reserve for elk herds, would have negligible affect on hunting activities, and that the effect of wolf predation on elk populations would not, in and of itself, have an impact sufficient to be the decisive factor in elk population management.
Although the reasons behind fluctuating wild animal populations are complex, Drs. Doug Smith, Daniel Stahler and John Vucetich conducted a joint National Park Service-MTU study into elk population at Yellowstone. Their findings found that:
  • Elk population remained stable from the re-introduction of wolves in 1995 through to 2000, at around 17,000
  • In the period 2000-2004 the population dropped 50% to 8,334. During this period the Greater Yellowstone Ecosystem area experienced drought conditions, and increased hunting of Elk by humans.
Though hunting permits did not allow for a kill level equivalent to the total population drop, the researchers concluded that hunting, led to a "super-additive" effect, whereby a 1% direct loss rate due to hunting was magnified to significant degree due to knock-on effects, which were only exacerbated by drought conditions. A recent study conducted by Montana Fish, Wildlife and Parks found that the primary killer of elk were mountain lions, followed by bears and wolves came in a distant third. Although wolf predation was acknowledged to exist, it's effect on the large population drops seen was regarded as a minor, largely insignificant factor:
"Our analysis indicates that there is greater justification
for believing that the harvest rate and severe climate,
together, account for at least much of the decline"
.

MYTH: Wolves attack humans all the time

While it is known that wolf attacks on humans do occur, those engaged in wolf hysteria deliberately exaggerate the risk out of all proportion to implant the idea in their audience that all wolves routinely kill and eat humans.
"Wolves are blood-thirsty predators that attack and kill pets, livestock, children, and adults"
"...we need to protect [the cattle industry] from these intruders...they’ve moved into my ecosystem,
not the other way around"
"258 Congressional Members Support Funding for Mexican Wolves Stalking Children and Wolves Terrorizing Rural Citizens"
The facts in no way bear out such hysteria. Those involved in wolf misinformation often recount reports from the 18th and 19th centuries recanting real or imagined wolf attacks in Europe and Asia. 

Although European wolf subspecies are less wary of humans, and are able to live near higher-density human populations than their North American cousins there are no reports of attacks. As the map clearly shows, no wolf subspecies present on the Eurasian landmass is present on the North American landmass.


Statistics compiled by Norwegian Institute for Nature Research (NINA) on global wild (not captive) wolf attacks show that in the period 1950-2000, (50 years) there were only 13 confirmed cases of wolf attacks on humans in North America, none of which were fatal.
In the United States alone, approximately 1 million reported instances of domestic dogs biting humans per year, with an average of 16 to 18 fatal attacks per year.

MYTH: Wolves spread disease

Groups and politicians opposed to wolf conservation often use the claim that wolves spread diseases to livestock and game populations. Whilst wolf populations, like that of any wild animal, carry disease, as apex predators they are more often than not a "dead end" for transmission of disease, and are of little concern when it comes to disease management in most livestock and game populations.
The most serious diseases affecting wolf populations are those which also affect domestic canines: parvo, mange and intestinal worms. In all cases, transmission of the disease is driven infinitely more by domestic dogs than wolves, and it is believed that in most cases these diseases have been introduced to the wolf population by domestic dogs. A notable exception is the presence of mange in North American wolf populations in the Rocky Mountains. This population was deliberately infected by government veterinarians in 1909 as an attempt to "exterminate" the wolf population, spread to coyotes and other mammals, and eventually re-infected wolves upon their reintroduction to the area.

MYTH: Killing/trapping/hunting is the solution

"I believe wolves need to be eliminated"
A common refrain is that the only effective solution to any or all of the above is to drastically reduce the population of wolves. This inevitably entails lethal intervention on the part of humans. Such actions are proposed by many livestock producers as the panacea to all ills, and is, unsurprisingly, encouraged and guided by the hunting, trapping and fur lobby organizations, which naturally present themselves as the only viable way of going about any such lethal solution. Unfortunately, many hunting methods are exceedingly inhumane, with methods such as leg traps being commonplace in North America, though are banned in the EU due to concerns over its inhumane nature.

The importance of predators: The Yellowstone case

Wolves were systematically killed in the Yellowstone region and many other areas of the West beginning in the late 1800s. A concentrated effort between 1914 and 1926 finished the job - the last known wolf pack disappeared in 1926.
This video provides a highly educational overview of the important role an apex predator like the
North American gray wolf plays in maintaining a healthy ecosystem.

Now, with the recent reintroduction of wolves back into Yellowstone in 1995, streamside shrubs and cottonwoods within the Lamar Valley are beginning to become more prevalent and taller, and were the focus of a second study in the same area. That study outlines how the fear of attack by wolves apparently prevents browsing elk from eating young cottonwood and willows in some streamside zones.
With the renewed presence of wolves, young cottonwoods and willows have been growing taller each year over on "high-risk" sites, where elk apparently feel vulnerable due to terrain or other conditions that might prevent escape. In contrast, on "low-risk" sites, they are still being browsed by elk and show little increase in height.
Traditionally, "keystone" predators such as wolves were known to influence the population of other animals that they preyed on directly, such as elk or antelope. What researchers are now coming to better understand is the "trophic effect," or cascade of changes that can take place in an ecosystem when an important part is removed.

Idaho damages its public image as well as its rural economy

Idaho Statesman - Guest Opinion

January 15, 2014

On a crisp December morning at the edge of the Lamar Valley in Yellowstone National Park, a steady stream of cars flowed to a pullout that was filled with hopeful visitors braving frigid temperatures in the predawn light to catch a glimpse of a pair of wolves that had been feeding on a road-killed bison. We were among the fortunate ones who got a parking spot that morning and were rewarded with a view of the wolves trotting along the creek bank in the early morning light, making for a magical, wild sight.
We returned to our car and soon heard a short news report on the wolf and coyote derby to be held in Salmon. A few days later while reading The New York Times, an editorial titled "wolf haters" negatively portrayed Idaho as it described the upcoming wolf derby, as well as Idaho Fish and Game's recent hiring of a professional wolf killer in the Frank Church-River of No Return Wilderness. The wolf derby not only infuriates the conservation community, but also many hunters interested in promoting ethical, fair and respectful hunting. The conservation community is questioning the legality of the hired hunter as a possible violation of the Wilderness Act. These recent events resulted in worldwide negative publicity for Idaho and have likely alienated potential visitors. Instead, Idaho could capitalize on tourism dollars by promoting the lucrative wolf-watching industry.
Look at Gardiner, Mont., as an example of a rural community benefiting from the presence of wolves. Just outside the north entrance to Yellowstone, we observed a bustling winter economy, largely driven by wolf watchers staying in hotels, patronizing restaurants and hiring wildlife watching outfitters. Couldn't and shouldn't Idaho foster this sustainable form of tourism in its rural communities instead of creating opportunities for the media to depict a state paralyzed by irrational fear and loathing of a predator that is a natural and important part of the state's ecosystems?
Some folks will cite the damage caused by wolves to Idaho's elk herds and livestock, as well as some who espouse the dangers to life and limb of just having predators in our midst, but consider some information that provides a more balanced view of the role of wolves and other wildlife here in Idaho:
• The amount of compensation paid to ranchers and farmers by Idaho Fish and Game related to wolves has been less than the amount of claims paid out for crop losses due to elk.
• Though wolves are vilified for preying on elk, black bears and mountain lions, whose populations far outnumber wolves, are major predators of elk.
• There are no documented cases of a wolf in Idaho injuring or killing a person. However, the Idaho Department of Transportation reports that since 1997, more than 27 human deaths resulted from vehicle collisions, mostly involving deer and elk.
• Other states have greater densities of both people and predators. Minnesota, Wisconsin and Michigan have approximately 2,000, 800 and 700 wolves, respectively. Densely populated New Jersey now has approximately 3,500 black bears. Idaho, on the other hand, appears to be fearfully preoccupied with fewer than 700 wolves.
There is a complex picture of how the wolf fits into Idaho. It's unfortunate that recent publicity has depicted our state as intolerant, disrespectful and ignorant with regard to dealing with this animal.
We need to repair this image, investigate additional ways to coexist, determine whether there are opportunities to embrace the wolf-watching economy in rural Idaho, and ensure that a more balanced picture of the wolf is presented to the country and the world.

For more wonder, rewild the world

Wolves were once native to Yellowstone National Park -- until hunting wiped them out. But when, in 1995, the wolves began to come back (thanks to an aggressive management program), something interesting happened: the rest of the park began to find a new, more healthful balance. In a bold thought experiment, George Monbiot imagines a wilder world in which humans work to restore the complex, lost natural food chains that once surrounded us.
In his book "Feral," George Monbiot advocates the large-scale restoration of complex natural ecosystems.

Should wild horses, wolves, be sacrificed for public lands ranchers

The dilemma has come down to this: Should ranchers be allowed to graze their livestock on public lands, then expect both Government help and public support for killing any native wildlife there that conflicts with their non-native livestock?
Point 1: When ranchers plunk herds of domestic livestock in the forest or wild wolf territory, there will be conflict with predators.
How can there not be? These are not 'problem wolves', coyotes or mountain lions; they are simply native wildlife trying to survive, in their own territories, in their wild lands, just as they always have throughout the ages. By dumping helpless, non-native, introduced cattle, sheep and other livestock onto designated wild lands, ranchers are deliberately and knowingly offering up their livestock to the wolves.

Global Cooling? - Dispelling An Enduring Myth With One Image


Courtesy John Cook at Skeptical Science
If the Earth’s temperature was the same year after year, then the effects of increasing greenhouse gases would be very easy to spot. Unfortunately, Mother Nature rarely makes things that easy to figure out. Besides the daily and seasonal cycles, we also have decadal temperature swings caused by the sunspot cycle and ocean/atmospheric oscillations. This tends to confuse non scientists, and fools many into believing claims that global warming has stopped. The Heartland Int. in Chicago (political think tank) has long been a major purveyor of this silliness.
John Cook, at Skeptical Science, has posted an incredible graphic that dispels this myth all by itself. This myth is very widespread, and if you google “global cooling” and you will see a plethora of web sites telling you the warming has ended and the planet is cooling. Those that believe this sort of thing will usually show a graph of temperatures to support it, but that graph will always cover just a few years. The image above shows why they do it that way; It’s kind of like saying that spring is cancelled because of an April cold snap!
Skeptical Science has an in-depth post that goes along with the graphic, and I highly recommend reading it. I’ll finally get to meet John Cook (at the December AGU conference) in San Francisco! He’s done an amazing job of showing the true science and dispelling the ubiquitous myths, that sound scientific, but are really just politics in disguise. Read it, and next time you’ll know when someone is giving you political belief dressed up to look like science.

Does Snow and Cold Weather Disprove Climate Change?


It’s Cold and My Car is Buried in Snow. Is Global Warming Really Happening?

Woman scrapes snow off of her car after cold weather and a snow stormFor years, climate contrarians have pointed to snowfall and cold weather to question the scientific reality of human-induced climate change.
Their annual barrage of misinformation obscures the interesting work scientists are doing to figure out just how climate change is affecting weather patterns year-round.
Understanding what scientists know about these effects can help us adapt. And, if we reduce the emissions that are driving climate change, we can avert its worst consequences in the future.

What is the relationship between weather and climate?

Weather is what’s happening outside the door right now; today a snowstorm or a thunderstorm is approaching. Climate, on the other hand, is the pattern of weather measured over decades.
NASA and NOAA plus research centers around the world track the global average temperature, and all conclude that Earth is warming. In fact, the past decade has been found to be the hottest since scientists started recording reliable data in the 1880s. These rising temperatures are caused primarily by an increase of heat-trapping emissions in the atmosphere created when we burn coal, oil, and gas to generate electricity, drive our cars, and fuel our businesses. Hotter air around the globe causes more water evaporation, which fuels heavier precipitation in the form of more intense rain and snow storms.
At the same time, because less of a region’s precipitation is falling in light storms and more of it in heavy storms, the risks of drought and wildfire are also greater. Ironically, higher air temperatures tend to produce intense drought periods punctuated by heavy floods, often in the same region.
These kinds of disasters may become a normal pattern in our everyday weather as levels of heat-trapping gases in the atmosphere continue to rise.
The United States is already experiencing more intense rain and snow storms. The amount of rain or snow falling in the heaviest one percent of storms has risen nearly 20 percent, averaged nationally—almost three times the rate of increase in total precipitation between 1958 and 2007.
Some regions of the country have seen as much as a 67 percent increase in the amount of rain or snow falling in the heaviest storms.

Don't Confuse Weather with Climate

The recent spate of Arctic cold that swept the nation has many questioning whether global warming is nothing more than a myth. It's almost comical for me to hear these rationalizations that the sub zero temperatures are proof positive that global warming is nothing more than a liberal strategy to generate unnecessary concern and anxiety in to the hearts of every patriotic, God fearing, hard working, and loyal American. It's equally amazing to me that these same folks can be so narrow minded as to ignore the scientific data that is available. They also apparently do not know the difference between "weather" and "climate".


Weather is short-term changes in the atmosphere: fluctuations in temperature, humidity, precipitation, cloudiness, brightness, visibility, wind, and barometric pressure. It can change from minute-to-minute, hour-to-hour, and day-to-day. Climate, on the other hand, is the average of weather over an extended period of time; it's the description of the long-term pattern of weather in a particular area. Climate is what you expect (like a hot summer), and weather is what you get.


So why was the Northeast so bitterly cold in December '09 and early January of 2010? How can they justify the theory of global warming, given the unusual sub zero temperatures? Some believe it was due to the normal changes in cyclical patterns like El Nino. I imagine that is possible, but with that, we still shouldn't ignore the fact that scientists have shown that the polar ice caps are melting.


One interesting theory that supports the argument of global warming and offers a possible explanation for the recent frigid temperatures is that as the sea ice melts, they dump cold, fresh water in to the oceans (much like adding an ice cube to a hot cup of tea). The ocean currents that carry the warmer air aloft along the east cost and on to Europe are rapidly cooling down. As a result, it's allowing for more intense cold and winter storms in areas typically tempered by what were warmer currents.



I love the winter, the cold weather and lots of snow. I'd move to Alaska tomorrow if I could . . . the problem is, that at the rate we're going, Alaska could soon have palm trees. Okay . . . so I'm being a bit facetious, but I've lived in the unbearably hot, humid "Sunshine State" for twelve years. I sincerely miss my good friends there, but one of the happiest days in my life was the day I saw the sign that said "You are now leaving the state of Florida". I have no interest in ever living in that kind of climate again.
