U.N. Scientist Rejects Nobel Prize Share, Denounces Climate Alarmism

Has the global warming alarmism movement hit its apex? Maybe so.

In recent weeks, we've seen a resurgence of hard scientists who have come out strongly against the warm-mongers, the latest of which is Intergovernmental Panel on Climate Change member John R. Christy. In an op-ed in today's Wall Street Journal, Christy tells the world that not only does he believe it's unproven that humans cause global warming, he's refusing his "share" of the Nobel Peace Prize that he was awarded because it was based on a misunderstanding of science.

An excerpt from this must-read op-ed:

I've had a lot of fun recently with my tiny (and unofficial) slice of the 2007 Nobel Peace Prize awarded to the Intergovernmental Panel on Climate Change (IPCC). But, though I was one of thousands of IPCC participants, I don't think I will add "0.0001 Nobel Laureate" to my resume.

The other half of the prize was awarded to former Vice President Al Gore, whose carbon footprint would stomp my neighborhood flat. But that's another story. Large icebergs in the Weddell Sea, Antarctica. Winter sea ice around the continent set a record maximum last month.

Both halves of the award honor promoting the message that Earth's temperature is rising due to human-based emissions of greenhouse gases. The Nobel committee praises Mr. Gore and the IPCC for alerting us to a potential catastrophe and for spurring us to a carbonless economy.

I'm sure the majority (but not all) of my IPCC colleagues cringe when I say this, but I see neither the developing catastrophe nor the smoking gun proving that human activity is to blame for most of the warming we see. Rather, I see a reliance on climate models (useful but never "proof") and the coincidence that changes in carbon dioxide and global temperatures have loose similarity over time.

There are some of us who remain so humbled by the task of measuring and understanding the extraordinarily complex climate system that we are skeptical of our ability to know what it is doing and why. As we build climate data sets from scratch and look into the guts of the climate system, however, we don't find the alarmist theory matching observations. (The National Oceanic and Atmospheric Administration satellite data we analyze at the University of Alabama in Huntsville does show modest warming -- around 2.5 degrees Fahrenheit per century, if current warming trends of 0.25 degrees per decade continue.)

It is my turn to cringe when I hear overstated-confidence from those who describe the projected evolution of global weather patterns over the next 100 years, especially when I consider how difficult it is to accurately predict that system's behavior over the next five days.

Mother Nature simply operates at a level of complexity that is, at this point, beyond the mastery of mere mortals (such as scientists) and the tools available to us. As my high-school physics teacher admonished us in those we-shall-conquer-the-world-with-a-slide-rule days, "Begin all of your scientific pronouncements with 'At our present level of ignorance, we think we know . . .'"

I haven't seen that type of climate humility lately. Rather I see jump-to-conclusions advocates and, unfortunately, some scientists who see in every weather anomaly the specter of a global-warming apocalypse. Explaining each successive phenomenon as a result of human action gives them comfort and an easy answer.

Others of us scratch our heads and try to understand the real causes behind what we see. We discount the possibility that everything is caused by human actions, because everything we've seen the climate do has happened before. Sea levels rise and fall continually. The Arctic ice cap has shrunk before. One millennium there are hippos swimming in the Thames, and a geological blink later there is an ice bridge linking Asia and North America.

One of the challenges in studying global climate is keeping a global perspective, especially when much of the research focuses on data gathered from spots around the globe. Often observations from one region get more attention than equally valid data from another.

Global Warming Comes to Neptune

Watching the global warming alarmists it's amazing to see how much they completely discount the sun's role in determining the earth's temperature. It's something that can be readily observed simply by stepping outside during the day and at night. Yet, we almost never hear the sun mentioned by Al Gore and friends.

This is despite the fact that astronomy continues to prove that the sun has an influence on its planets temperatures and is likely to be responsible for observable warming of the earth. First came the news that Mars is getting warmer, now comes the news that Neptune is also experiencing global warming:

Neptune is the planet farthest from the Sun (Pluto is now considered only a dwarf planet), Neptune is the planet farthest from the Earth, and to our knowledge, there has been absolutely no industrialization out at Neptune in recent centuries. There has been no recent build-up of greenhouse gases there, no deforestation, no rapid urbanization, no increase in contrails from jet airplanes, and no increase in ozone in the low atmosphere; recent changes at Neptune could never be blamed on any human influence. Incredibly, an article has appeared in a recent issue of Geophysical Research Letters showing a stunning relationship between the solar output, Neptune’s brightness, and heaven forbid, the temperature of the Earth. [...]

In the recent article, Hammel and Lockwood, from the Space Science Institute in Colorado and the Lowell Observatory, note that measurements of visible light from Neptune have been taken at the Lowell Observatory in Flagstaff, Arizona since 1950. Obviously, light from Neptune can be related to seasons on the planet, small variations in Neptune’s orbit, the apparent tilt of the axis as viewed from the Earth, the varying distance from Neptune to Earth, and of course, changes in the atmosphere near the Lowell Observatory. Astronomers are clever, they are fully aware of these complications, and they adjust the measurements accordingly. [...]

Neptune has been getting brighter since around 1980; furthermore, infrared measurements of the planet since 1980 show that the planet has been warming steadily from 1980 to 2004. As they say on Neptune, global warming has become an inconvenient truth. But with no one to blame, Hammel and Lockwood explored how variations in the output of the Sun might control variations in the brightness of Neptune. [...]

Hammel and Lockwood conclude that “In summary, if Neptune’s atmosphere is indeed responding to some variation in solar activity in a manner similar to that of the Earth albeit with a temporal lag” then “Neptune may provide an independent (and extraterrestrial) locale for studies of solar effects on planetary atmospheres.”

Gore Gets a Little Too Religious for Liberal Enviro

Al Gore's prophecy tour of doom hit a snag the other day. Apparently, he caused a stir among some atheist environmentalists for stating that he believes in creation science. Amazingly, no one in the media has picked it up. The irony is especially delicious since many on the left are making fun of some of the GOP presidential candidates for having the same belief.

One liberal Canadian blogger who was at a Gore presentation reports Gore's act of blasphemy:

The slide I found particularly interesting/shocking/sad, was his new(?) slide containing a graph of human population growth over the past couple hundred-thousand years. It started off good. He pointed at the beginning of the graph, showing the population of humans on Earth from 200,000 years ago, and referred to the “rise of humans." Cool beans. So he believes that Homo sapiens evolved from other hominid ancestors, right? Nope.

In the very same breath, he then continued to explain that according to his religious beliefs, this “rise of humans” was God’s creation of mankind - apparently 200,000 years ago. His graph then changed to include the caption “Adam & Eve” above this starting point.

I started laughing, and I had to consciously blink my eyes and double-check the screen to make sure I was seeing it properly. Let me get this straight...the guy's entire presentation exists in order to present people with the scientific data showing that human-caused climate change is a fact. He does his very best to include references in all of the slides, showing to any thinking person that this data is not made up, that it comes from the forefront of our scientific research (there was many slides containing data from Science journal, and a few from Nature).

He tarnishes his beautifully crafted presentation by not only stating his belief in creationism - but by placing the words “Adam and Eve” right on the slide (which is actually a scientific graph) as a caption explaining the beginnings of mankind.

Something doesn't add up here. On one hand, he is using science to predict the disastrous outcome of our current actions and rally support for taking proactive measures to make sure bad things don't happen, but on the other hand, he is clinging to stone-age beliefs that another very important area of science has proven wrong (that we humans evolved from other forms of life, and that every organism on Earth has a common ancestor).

And of course, all the religious people in the audience get to feel good knowing that this important politician sees no dilemma in using this this zero-sum belief system. I should also note that at this point in the lecture (I'll call it the schism) he stated that there is no conflict between science and religion. He appeared as though he wanted to say more about this, and even mentioned the Scopes trial, but then decided to continue on with the slideshow instead.

Whaaaaa???? You tell me that anthropogenic climate change is a scientific fact (to the degree that science can use that word), mankind came from God's creation of Adam and Eve 200,000 years ago, there is no conflict between science and religion, refer to the Scopes trial, and then shrug it off and move on with the show?

Is Global Warming a Sin?

Despite Al Gore and friends' best hopes, not everyone on the left is running around proclaiming catastrophe when it comes to global warming. One such liberal is Alexander Cockburn who is uneasy about just how close alarmist global warming rhetoric seems to be to a religion:

In a couple of hundred years, historians will be comparing the frenzies over our supposed human contribution to global warming to the tumults at the latter end of the tenth century as the Christian millennium approached. Then, as now, the doomsters identified human sinfulness as the propulsive factor in the planet's rapid downward slide.

Then as now, a buoyant market throve on fear. The Roman Catholic Church was a bank whose capital was secured by the infinite mercy of Christ, Mary and the Saints, and so the Pope could sell indulgences, like checks. The sinners established a line of credit against bad behavior and could go on sinning. Today a world market in "carbon credits" is in formation. Those whose "carbon footprint" is small can sell their surplus carbon credits to others, less virtuous than themselves.

The modern trade is as fantastical as the medieval one. There is still zero empirical evidence that anthropogenic production of CO2 is making any measurable contribution to the world's present warming trend. The greenhouse fearmongers rely entirely on unverified, crudely oversimplified computer models to finger mankind's sinful contribution. Devoid of any sustaining scientific basis, carbon trafficking is powered by guilt, credulity, cynicism and greed, just like the old indulgences, though at least the latter produced beautiful monuments. By the sixteenth century, long after the world had sailed safely through the end of the first millennium, Pope Leo X financed the reconstruction of St. Peter's Basilica by offering a "plenary" indulgence, guaranteed to release a soul from purgatory.

Cockburn spends some additional time on the science behind it all in the rest of the article. Read it for a user-friendly look.
