Climate Change

The UK Telegraph is reporting that several prominent scientists whose work and opinions were included in the recent documentary “The Great Global Warming Swindle” (see review) have received threats from environmentalists - many threatening their lives (h/t Noel Sheppard at Newsbusters):

Scientists who questioned mankind’s impact on climate change have received death threats and claim to have been shunned by the scientific community.

They say the debate on global warming has been “hijacked” by a powerful alliance of politicians, scientists and environmentalists who have stifled all questioning about the true environmental impact of carbon dioxide emissions.

Timothy Ball, a former climatology professor at the University of Winnipeg in Canada, has received five deaths threats by email since raising concerns about the degree to which man was affecting climate change.

Many alarmists like to use the “why would we lie about anthropogenic global warming” claim and Ball hits the nail on the head of one of many reasons why:

“Western governments have pumped billions of dollars into careers and institutes and they feel threatened,” said the professor.

These tactics are nothing new in the world of science:

Nigel Calder, a former editor of New Scientist, said: “Governments are trying to achieve unanimity by stifling any scientist who disagrees. Einstein could not have got funding under the present system.”

Einstein is but one who wouldn’t receive funding… the same could be said for many other great scientists who were shunned for their against-the-grain work. Ball, Calder, and many others deserve a place in history along the lines of many other great “skeptics”: Galileo, Copernicus, Hutton, and Darwin.

Finally, a well-sourced, scientific rebuttal to the mainstream media’s portrayal of global warming, not to mention their embrace of Al Gore’s “An Inconvenient Truth”: The Great Global Warming Swindle.

This is a welcome film debunking the popular viewpoint, including explaining the evidence that the Earth’s climate is always changing and there is less than convincing evidence that the climate is driven significantly by CO2 concentrations. Furthermore, volcanoes produce more CO2 each year than all human-made sources put together. Should we plug them up?

The Sun Drives Climate Change

The current warming trend has been ongoing since long before our introduction of CO2-emitting vehicles…not to mention, the four decade span in the middle-20th century during which global temperatures dropped - the same period when the automobile ownership hit record levels year after year. For just a sampling of the data made available in this documentary, let’s examine the correlation between solar activity and the global temperature variations. The last century is the single period during which we have the most reliable temperature data (direct measurements) and when the CO2 concentration is graphed with temperature variation on Earth, the correlation is weak - particularly during the cooling period from the 1940s through the 1970s. For a stronger correlation, solar activity can be lined up (source):

Who’s presenting this information - another politician? Nope - not this one. This documentary is composed primarily of interviews and discussions with meteorologists, atmospheric scientists, and climatologists from around the world. Many of those interviewed are contributors to the UN’s now infamous series of Intergovernmental Panel on Climate Change (IPCC) reports - the most recent of which makes the unjustified claim of an “unequivocal” connection between anthropogenic greenhouse gas production and global climate change.

Says Who?

But you thought the IPCC report was a consensus view of anthropogenic climate change, you say? Not so fast. Many of those listed as authors are far from in agreement on this issue - as they express in their own words in this documentary.

For more on scientists with the contrarian viewpoint, check out this list of 89 climate experts (pdf) - professors, climatologists, and the like - who disagree with the supposed consensus view of anthropogenic climate change, as made available in this newsbusters.org thread. (The list includes a professor from my alma mater, Dr. Al Pekarek).

It’s like a game…which mainstream media outlet will jump on the global warming alarmist bandwagon next?

Sports Illustrated is publishing a cover story regarding the implications of climate change on the sports world. But they aren’t just discussing climate change - they’re going after “environmental crisis” that is created by humans. What about natural causes for climate change? Nah - no mention of those. What about the impossibility of meaningful prediction? That’s just a minor detail not worthy of mentioning. No - those aren’t important…instead, they lean on many of the tired, token doom-and-gloom catch phrases:

If we continue to spew greenhouse gases as we are, the Earth could become five degrees warmer this century. The last time Earth was that warm, three million years ago, sea level stood 80 feet higher than it does now.

Humans are accelerating global warming …

Decrease the burning of fossil fuels…

and my personal favorite:

Every organism on the planet is already feeling its impact.

After the usual rant, including the warnings about how disastrous the Earth will be by 2100, they get specific, giving an example that is entirely at odds with published, refereed research. Sports Illustrated says:

Tropical storms become more powerful over a warmer Gulf, turning a category 4 storm, for example, into a category 5, like Katrina, which transformed the symbol of sports in New Orleans, the Superdome, into an image of epic disaster

Yet, reports to the contrary have been available for over a year. In mid-2006, National Geographic Magazine published an article questioning the global warming and hurricane intensity link:

An expert with the U.S. National Oceanic and Atmospheric Administration (NOAA) is questioning the connection between climate change and the appearance of more intense hurricanes in recent years. Historical data on hurricanes is too crude to determine long-term trends in intensity, says Christopher Landsea, a science and operations officer with NOAA’s National Hurricane Center in Miami, Florida.

And in late 2005, NOAA attributed the strength of the 2005 Atlantic hurricane season (the one that included Katrina) to “naturally-occuring climate variability“:

There is consensus among NOAA hurricane researchers and forecasters that recent increases in hurricane activity are primarily the result of natural fluctuations in the tropical climate system known as the tropical multi-decadal signal. The tropical climate patterns now favoring very active hurricane seasons are similar to those seen in the late 1920s to the late 1960s.

More concisely (NOAA):

No individual tropical cyclone can be directly attributed to climate change.

In fact, the article goes on to cite specific, anecdotal events (those of us in the meteorology field refer to this as “weather”) rather than long term trends (also known as “climate”). A primary rule in the climate change discussion is that single, isolated events can not be deemed evidence as long-term change.

So remind me again what qualifications the Sports Illustrated staff has when it comes to climatology?

The author of the Sports Illustrated cover story apparently (assuming there is just one Alexander Wolff employed by AOL Time Warner - the parent company of Sports Illustrated) has been a generous contributor to Howard Dean and the DNC. A search for the individual “Wolff, Alexander” on OpenSecrets.org yields 6 results over the last several election cycles: A $500 donation to Howard Dean in addition to a total of $1120 in campaign contributions directly to the DNC.

It appears as though solar variability is gaining some mainstream media attention in being cited as a likely impetus for terrestrial climate change. But for confirmation of this, scientists have now begun to look beyond the Earth to other areas of our solar system. Most recently, research on the climate of Mars has confirmed warming that appears to be mirroring that of the Earth. Is my SUV destroying the climate of Mars too? As published by National Geographic, (Mars melt hints at solar, not human, cause for warming, scientist says) recent work citing solar variability as a primary cause of climate change here on Earth is gaining traction:

“Man-made greenhouse warming has made a small contribution to the warming seen on Earth in recent years, but it cannot compete with the increase in solar irradiance,” Abdussamatov said.

By studying fluctuations in the warmth of the sun, Abdussamatov believes he can see a pattern that fits with the ups and downs in climate we see on Earth and Mars.

As an aside, it should be noted that warming on mars is nothing new - it has been observed for years and Nasa has been gathering ever-increasingly detailed data from the martian poles via the Mars Global Surveyor:

And for three Mars summers in a row, deposits of frozen carbon dioxide near Mars’ south pole have shrunk from the previous year’s size, suggesting a climate change in progress.

Abdussamatov is not alone in citing solar variability - fluctuating energy output from the sun - as a major factor in the Earth’s climate. Just last month, research published in NewScientist Online explores evidence of a relationship between solar variability and the ice age cycles on Earth (Sun’s fickle heart may leave us cold). Work completed by George Ehrlich of Geoge Mason University concludes:

There’s a dimmer switch inside the sun that causes its brightness to rise and fall on timescales of around 100,000 years - exactly the same period as between ice ages on Earth. So says a physicist who has created a computer model of our star’s core…

The article discusses many of the oscillations that control the temperature of the sun’s surface:

Ehrlich’s model shows that whilst most of these oscillations cancel each other out, some reinforce one another and become long-lived temperature variations. The favoured frequencies allow the sun’s core temperature to oscillate around its average temperature of 13.6 million kelvin in cycles lasting either 100,000 or 41,000 years. Ehrlich says that random interactions within the sun’s magnetic field could flip the fluctuations from one cycle length to the other.

These two timescales are instantly recognisable to anyone familiar with Earth’s ice ages: for the past million years, ice ages have occurred roughly every 100,000 years. Before that, they occurred roughly every 41,000 years.

For details, check out the full text of Ehrlich’s research. While recent work has explored a correlation between solar variability and terrestrial climate cycles, none have explored the potential mechanism until now, writes Ehrlich in his abstract:

A theory is described based on resonant thermal diffusion waves in the sun that appears to explain many details of the paleotemperature record for the last 5.3 million years. These include the observed periodicities, the relative strengths of each observed cycle, and the sudden emergence in time for the 100 thousand year cycle. Other prior work suggesting a link between terrestrial paleoclimate and solar luminosity variations has not provided any specific mechanism. The particular mechanism described here has been demonstrated empirically, although not previously invoked in the solar context.

As mentioned in a 2005 Duke University publication, the sun’s role in global warming is likely underestimated:

At least 10 to 30 percent of global warming measured during the past two decades may be due to increased solar output rather than factors such as increased heat-absorbing carbon dioxide gas released by various human activities, two Duke University physicists report.

Work published in Science Magazine in 2001 (Persistent Solar Influence on North Atlantic Climate During the Holocene) cites specific influences of solar variability on the climate of the North Atlantic:

Surface winds and surface ocean hydrography in the subpolar North Atlantic appear to have been influenced by variations in solar output through the entire Holocene.

Bond et al. confirm the likelyhood that the particular influence on the North Atlantic may have been transmitted globally:

The surface hydrographic changes may have affected production of North Atlantic Deep Water, potentially providing an additional mechanism for amplifying the solar signals and transmitting them globally.

Given that the sun has a profound impact on the climate of the globe, it naturally follows that any solar variability to influence the Earth’s climate in one location will have its affects felt throughout the globe.

• Another Global Warming Skeptic Rebuked (February 27, 2007)
• Global Warming Alarmists: Time out (Feburary 4, 2007)
• Silencing the Skeptics (January 19, 2007)

The state of Delaware has rebuked their state climatologist, attempting to distance themselves (or at least the Governor is) from their “state climatologist” over disagreements in the state’s official stance on global warming. Not only are they attempting to distance themselves, they are attempting to remove his title as “state climatologist”:

WILMINGTON, Del. — Gov. Ruth Ann Minner has directed Delaware’s state climatologist to stop using his title in public statements on climate change, citing a clash of views on global warming and confusion over the position’s ties to the administration.

Minner, who made the directive in a letter, described the move as a way to “clarify” the role of David R. Legates, a prominent skeptic of views that human activities are warming the planet and triggering climate shifts. “Your views on climate change, as I understand them, are not aligned with those of my administration,” Minner wrote.

The governor attempts to place blame on the “confusion” of the title and rather than simply making the title more official, the decision was made to drop the title all together (emphasis mine):

“In light of my position and due to the confusion surrounding your role with the state, I am directing you to offer any future statements on this or other public policy matters only on behalf of yourself or the University of Delaware,” Minner wrote, “and not as state climatologist.”

Legates, who could not be reached Wednesday, has not returned phone calls since The News Journal published articles about his position on climate change. His title was accepted by the American Association of State Climatologists and the National Climatic Data Center, and acknowledged by Minner and the university’s provost in 2005. But Legates received no appointment or state money to support his office at the University of Delaware, where he is also a professor of geography. His position as climatologist carries no state authority.

Legates also served as an unpaid “adjunct scholar” with the National Center for Policy Analysis, and had a paper published by that group arguing that science “does not support” claims of drastic warming or human influence on weather or climate shifts. He has previously referred to global warming arguments as “climate alarmism.”

So in summary, the state climatologist - the one with the science degree(s) - has been rebuked for his views on science. For some readers, this is probably beginning to sound a little familiar. This the second of such occurrences, mirroring the January dismissal of Oregon’s state climatologist who also disagreed with the governor on climate change issues, stating simply:

“There are a lot of people saying the bulk of the warming of the last 50 years is due to human activities and I don’t believe that’s true.” He believes natural cycles explain most of the changes the earth has seen.

Which of these governors has formal education in meteorology or climatology? This is an incredibly dangerous precident that deserves more attention that it has received.
