Here’s something you don’t see every day: a president of a major environmental group sending an e-mail message to a colleague threatening to ruin that person’s career over disagreements regarding anthropogenic global warming.
Yet, as published at National Review Online’s “The Corner” on Friday, that’s exactly what happened just days after a Competitive Enterprise Institute senior fellow wrote an article for the American Spectator which spoke against proposed legislation to mandate carbon dioxide emissions reductions.
According to National Review’s Iain Murphy, the author, Dr. Marlo Lewis, received the following e-mail message this morning (one character edited by Murphy for vulgarity):
Marlo –
You are so full of cr*p.
You have been proven wrong. The entire world has proven you wrong. You are the last guy on Earth to get it. Take this warning from me, Marlo. It is my intention to destroy your career as a liar. If you produce one more editorial against climate change, I will launch a campaign against your professional integrity. I will call you a liar and charlatan to the Harvard community of which you and I are members. I will call you out as a man who has been bought by Corporate America. Go ahead, guy. Take me on.
Mike
Michael T. Eckhart
President
American Council On Renewable Energy (ACORE)
I guess that’s one way to end the debate.

Certainly a powerful way to put an end to any further scientific debate. "You're wrong, I'm right and if you discuss it further, I will destroy you." Wow!

July 13, 2007 - 18:05 ET by Dave R'noon, bt,
I doubt Dr. Lewis needs to be concerned, now that this email has been made public. Mr. Eckhart screwed up royally by sending that email, even if it was in the heat of the moment (which will be what he will claim when querried on it, I'm guessing).
Now any adverse move he makes that is aimed in the direction of Dr. Lewis would be scrutinized most severely.
I do wonder, though, just how often this happens within the scientific community and goes un-reported to the outside world.

Will it be reported?
July 13, 2007 - 21:14 ET by pbthinkerWho's going to report it, besides NewsBusters? Will anyone, in the MSM, ask the pertinent questions about this e-mail? Hopefully, Mother Nature, will prove who's right, in this debate. There's snow, in the Southern Hemisphere, in places that haven't had snow in years, Australia had the coldest June since 1950, and our Summer has been pretty normal, as things go. The MSM has been trying to gin up the high temperatures, out West, but there really isn't enough unusual for them to make a big deal about it.
Never argue with an idiot. They'll drag you down to their level and beat you with experience.
Are the "climate change" types getting a little deperate?
July 13, 2007 - 17:09 ET by Dave RI sense a high level of frustration in Mr. Eckhart's childish little rant. Perhaps he senses the "climate change" movement is losing momentum and is lashing out at Dr. Lewis in a different twist on the "If you don't play by my rules, I'll take my ball ....." story. Only, in this version, he plans to leave the playground with Dr. Lewis'.
Either that or he's trying to land a date with that like-minded Heidi Cullen woman in a fashion eerily similar to the way John Hinckly, Jr. was attempting to impress Jodie Foster.
I think this Eckhart guy has some serious emotional issues.

Models trump measurements
Lawrence Solomon
Financial Post
Published: Saturday, July 07, 2007
We are doomed, say climate change scientists associated with the United Nations Intergovernmental Panel on Climate Change, the United Nations body that is organizing most of the climate change research occurring in the world today. Carbon dioxide from man-made sources rises to the atmosphere and then stays there for 50, 100, or even 200 years. This unprecedented buildup of CO2 then traps heat that would otherwise escape our atmosphere, threatening us all.
"This is nonsense," says Tom V. Segalstad, head of the Geological Museum at the University of Oslo and formerly an expert reviewer with the same IPCC. He laments the paucity of geologic knowledge among IPCC scientists -- a knowledge that is central to understanding climate change, in his view, since geologic processes ultimately determine the level of atmospheric CO2.
"The IPCC needs a lesson in geology to avoid making fundamental mistakes," he says. "Most leading geologists, throughout the world, know that the IPCC's view of Earth processes are implausible if not impossible."
Catastrophic theories of climate change depend on carbon dioxide staying in the atmosphere for long periods of time -- otherwise, the CO2 enveloping the globe wouldn't be dense enough to keep the heat in. Until recently, the world of science was near-unanimous that CO2 couldn't stay in the atmosphere for more than about five to 10 years because of the oceans' near-limitless ability to absorb CO2.
"This time period has been established by measurements based on natural carbon-14 and also from readings of carbon-14 from nuclear weapons testing, it has been established by radon-222 measurements, it has been established by measurements of the solubility of atmospheric gases in the oceans, it has been established by comparing the
isotope mass balance, it has been established through other mechanisms, too, and over many decades, and by many scientists in many disciplines," says Prof. Segalstad, whose work has often relied upon such measurements.
Then, with the advent of IPCC-influenced science, the length of time that carbon stays in the atmosphere became controversial. Climate change scientists began creating carbon cycle models to explain what they thought must be an excess of carbon dioxide in the atmosphere. These computer models calculated a long life for carbon dioxide.
Amazingly, the hypothetical results from climate models have trumped the real world measurements of carbon dioxide's longevity in the atmosphere. Those who claim that CO2 lasts decades or centuries have no such measurements or other physical evidence to support their claims.
Neither can they demonstrate that the various forms of measurement are erroneous.
"They don't even try," says Prof. Segalstad. "They simply dismiss evidence that is, for all intents and purposes, irrefutable. Instead, they substitute their faith, constructing a kind of science fiction or fantasy world in the process."
In the real world, as measurable by science, CO2 in the atmosphere and in the ocean reach a stable balance when the oceans contain 50 times as much CO2 as the atmosphere. "The IPCC postulates an atmospheric doubling of CO2, meaning that the oceans would need to receive 50 times more CO2 to obtain chemical equilibrium," explains Prof. Segalstad. "This total of 51 times the present amount of carbon in atmospheric CO2 exceeds the known reserves of fossil carbon-- it represents more carbon than exists in all the coal, gas, and oil that we can exploit anywhere in the world."
Also in the real world, Prof. Segalstad's isotope mass balance calculations -- a standard technique in science -- show that if CO2 in the atmosphere had a lifetime of 50 to 200 years, as claimed by IPCC scientists, the atmosphere would necessarily have half of its current CO2 mass. Because this is a nonsensical outcome, the IPCC model postulates that half of the CO2 must be hiding somewhere, in "a missing sink." Many studies have sought this missing sink -- a Holy Grail of climate science research-- without success.
"It is a search for a mythical CO2 sink to explain an immeasurable CO2 lifetime to fit a hypothetical CO2 computer model that purports to show that an impossible amount of fossil fuel burning is heating the atmosphere," Prof. Segalstad concludes.
"It is all a fiction."

Oldest DNA ever recovered shows warmer planet: report
http://www.breitbart...
Scientists who probed two kilometers (1.2 miles) through a Greenland glacier to recover the oldest plant DNA on record said Thursday the planet was far warmer hundreds of thousands of years ago than is generally believed.
DNA of trees, plants and insects including butterflies and spiders from beneath the southern Greenland glacier was estimated to date to 450,000 to 900,000 years ago, according to the remnants retrieved from this long-vanished boreal forest.
That contrasts sharply with the prevailing view that a lush forest of this kind could only have existed in Greenland as recently as 2.4 million years ago, according to a summary of the study, which is published Thursday in the journal Science.
The samples suggest the temperature probably reached 10 degrees C (50 degrees Fahrenheit) in the summer and -17 C (1 F) in the winter.
They also indicated that during the last period between ice ages, 116,000-130,000 years ago, when temperatures were on average 5 C (9 F) higher than now, the glaciers on Greenland did not completely melt away.
"These findings allow us to make a more accurate environmental reconstruction of the time period from which these samples were taken," said Martin Sharp, a glaciologist at the University of Alberta, Canada, and a co-author of the paper.
"What we've learned is that this part of the world was significantly warmer than most people thought."
In a separate paper, also published in Science, European experts said they had analysed the world's deepest ice core, enabling them to reconstruct patterns of warming and glaciation over the past 800,000 years.
The 3,260-metre (10,595-feet) core was drilled into the East Antarctica icesheet at the Franco-Italian base, Dome C. The drillers, gathered in a venture called the European Project for Ice Coring in Antarctica (EPICA) stopped just 15 metres (48.75 feet) short of the bedrock.
Using traces of the hydrogen isotope deuterium in air bubbles trapped in the ice layers, the scientists built a record of greenhouse-gas concentrations over the aeons, which in turn provides a record of temperature.
They found the temperature varied widely, by as much as 15 C (27 F) over the 800,000 years. In the last Ice Age, which ended around 11,000 years ago, the temperature was 10 C (18 F) lower than today.
The EPICA team had previously analysed the Dome C core to a depth equivalent to 650,000 years ago.
Greenland ice yields hope on climate
DNA hints warm era didn't melt entire cap
By Colin Nickerson, Globe Staff | July 6, 2007
An international team of scientists, drilling deep into the ice layers of Greenland, has found DNA from ancient spiders and trees, evidence that suggests the frozen shield covering the immense island survived the earth's last period of global warming.
The findings, published today in the journal Science, indicate Greenland's ice may be less susceptible to the massive meltdown predicted by computer models of climate change, the article's main author said in an interview.
"If our data is correct, and I believe it is, then this means the southern Greenland ice cap is more stable than previously thought," said Eske Willerslev, research leader and professor of evolutionary biology at the University of Copenhagen. "This may have implications for how the ice sheets respond to global warming. They may withstand rising temperatures."
Scientists not involved in the study cautioned, however, that current climate change is so driven by pollution from power plants, industry, and other human activity that it is nearly impossible to draw a meaningful conclusion about the durability of Greenland's ice.
"Whatever occurred in the past almost surely occurred much more slowly," said Raymond S. Bradley, director of the Climate System Research Center at the University of Massachusetts at Amherst. "Human activity is pushing warming at a much faster rate than in the past. Change is occurring in decades or centuries, not over millennia."
A painstaking analysis of surviving genetic fragments locked in the ice of southern Greenland shows that somewhere between 450,000 and 800,000 years ago, the world's largest island had a climate much like that of Northern New England, the researchers said. Butterflies fluttered over lush meadows interspersed with stands of pine, spruce, and alder.
Greenland really was green, before Ice Age glaciers enshrouded vast swaths of the Northern Hemisphere.
More controversially -- and as an example of how research in one realm of science can unexpectedly affect assumptions in another -- the discovery of microscopic bits of organic matter retrieved from ice 1.2 miles beneath the surface indicates that the ice fields of southern Greenland may be more resilient to rising global temperatures than has been forecast. The DNA could have been preserved only if the ice layers remained largely intact.
A scenario often raised by global warming specialists is that Greenland's ice trove will turn liquid in the rising temperatures of coming decades, with hundreds of trillions of gallons of water spilling into the Atlantic. This could cause ocean levels worldwide to rise anywhere from 3 to 20 feet, according to computer projections -- bad news for seaport cities like Boston.
But the discovery of organic matter in ice dating from half-a-million years ago offers evidence that the Greenland ice shield remained frozen even during the earth's last "interglacial period" -- some 120,000 years ago -- when average temperatures were 9 degrees Fahrenheit warmer than they are now. That's slightly higher than the average temperatures foreseen by most scientists for the end of this century, although some environmentalists warn it might get even hotter.Continued...

But the discovery of organic matter in ice dating from half-a-million years ago offers evidence that the Greenland ice shield remained frozen even during the earth's last "interglacial period" -- some 120,000 years ago -- when average temperatures were 9 degrees Fahrenheit warmer than they are now. That's slightly higher than the average temperatures foreseen by most scientists for the end of this century, although some environmentalists warn it might get even hotter.
Researchers from the Danish-led team said the unanticipated findings appear to fly in the face of prevailing scientific views about the likely fate of Greenland's thickly-layered ice, although Willerslev stressed that the findings do not contradict the basic premise that the earth's temperature is rising to worrisome levels, with gases emitted by industry, cars, and other human activity playing a big role.
"But it suggests a problem with the [computer] models" that predict melting ice from Greenland could drown cities and destroy civilizations, according to Willerslev.
"We should remain very worried about rising sea levels," he said. "We know that during the last interglacial, sea levels rose by 5 meters or more. But this must have come from sources additional to Greenland, such as Antarctic ice. It does not appear the whole [Greenland] sheet will melt."
Computer models suggest that Greenland and Antarctica will be the main contributors to rising sea levels as the climate warms. (The Arctic won't affect sea level, because its ice already floats in the ocean.)
Some scientists not involved in the study drew a conclusion very different from that of the Danish-led team .
"The raw results of this study are very impressive -- southern Greenland was unglaciated sometime during the last million years or so," said Gavin Schmidt, a climatologist with National Aeronautics and Space Administration 's Goddard Institute for Space Studies. "I would argue that this implies a more unstable ice sheet, not the opposite."
Schmidt said that during the more recent warming period, most but not all of the ice might have disappeared from southern Greenland, leaving a thin layer that would have been sufficient to preserve the DNA.
The organic matter found in ice cores taken from a southern Greenland drilling site known as Dye 3 represent s the oldest-ever authenticated DNA found by scientists to date, with fragments of beetles, tree bark, prehistoric spiders, and other life verified independently in laboratories in Denmark, Canada, and Germany.
"The ice sheet served as a deep freezer, preserving organic materials for amazingly long periods," said Martin Sharp, a University of Alberta glaciologist who participated in the Greenland research.
Scientists were able to isolate only about 1.6 ounces of organic matter from the ice at the bottom of the core sample, according to Enrico Cappellini, a researcher specializing in ancient proteins at Britain's University of York.
But that was enough to extract genetic traces of long-vanished plants and insects, enabling scientists to envision in fine detail a prehistoric landscape.
"The genetic material presents a biological environment that is completely different from the Greenland we see today," said Willerslev. "We found grain, pine, yew, and alder. We found traces of spiders, beetles, ancient butterflies."
The identifications were made by comparisons with genetic material from existing species.
Analysis of the insect mitochondria, cellular components that contain genomes that can be used to date DNA, as well as amino acids, indicate d that the creatures were at least 450,000 years old. Uncertainties with dating, however, leave the possibility that the DNA dated only as far back as the last interglacial period.
The identification of such relatively well-preserved genetic material beneath ice sheets was exciting news for biologists. Ten percent of the earth's surface has been covered by deep ice for tens of thousands of years. "We could be opening up a frozen world of new discoveries," said Cappellini, the University of York researcher.
In terms of its name, Greenland was the original snow job.
Erik the Red -- a famous Viking banished first from Norway and then Iceland for murdering his neighbors -- sailed his longship to the uninhabited island in 982 AD. Showing an intuitive flair for PR, Erik sent back word of a bountiful "green land" as a way of enticing others to follow him to fjords at the southwestern tip of the island. In medieval times, the climate in the region was just warm enough to permit cultivation of some rugged crops and the raising of livestock.
The Nordic settlements -- the first European presence in the New World -- survived for nearly 500 years before mysteriously disappearing. Historians speculate that either the inhabitants starved as Greenland grew colder or they were killed by Inuit, who appeared on the scene around 1200 AD.

Through all of that ton. You
July 14, 2007 - 14:04 ET by danboThrough all of that ton. You stated that the Name of Greenland was the original snow job. I've seen such statements on the web. Yet can find not verification of these statements, from the Sagas or anywhere else. And these sites do not back up these statements. Greenland was not quickly renamed Eric's folly or Eric's a liar land. May I ask why?
Further if my memory is correct at the garden under the sandet as well as other locations they found roots in the permafrost. As permafrost is the limit of root formation this implies a warmer environment. The ruins of Viking communities indicates a colony that grew than slowly died. Even though ships from Denmark or Iceland were very rare.
The mean temperture for Godthab Nuuk, Greenland dropped from a little over plus 1*C in the early 1940's to about minus 4.5*C in the early 80's. That's a mean of 5 degrees in about 40 years . And has only returned to about a mean of 0*C.
Please provide your evidence/proof that Eric was lying?
