Global Warming

I created this when I was bored. I painted it in Photoshop CS2, just from my imagination. It's just a non-specific planet.




GLOBAL WARMING
“The weight of scientific evidence shows that “global warming” began 300 years ago, at the end of an unusually prolonged period of comparative solar inactivity known as the Maunder Minimum, and has continued since then at a near-uniform 1 F per century. Throughout most of that long period of warming, we were not numerous enough or industrially active enough to have made any impact on mean global surface temperatures whatsoever (Akasofu, 2007). The last year which set a record for mean global surface temperature was 1998, when an exceptional but not unprecedented El Nino Southern Oscillation caused a sharp spike in global temperatures as stored heat was released from the world’s oceans to the atmosphere. Note that the instrumental temperature record began only in 1880; and, given the long-run rising trend in global temperatures, higher temperatures at the end of the period of record are scarcely surprising.

Since 1998 no new annual temperature record has been set. Since late 2001, linear-regression trends for all four of the major global-temperature datasets have been downward (Figure 1). The drop in temperature between January 2007 and January 2008 was the greatest since instrumental records began in 1880. Whatever else is happening in the climate, “global warming” is not “happening now” and has not been happening for a decade. No new annual global-temperature record is expected until 2015 (Keenlyside et al., 2008).. Not one of the computer models predicted this long period of global cooling. In the month of June 2008, exactly 20 years after James Hansen’s forecast to Congress that global temperatures would rise sharply, global temperatures were actually cooler than they had been when he made the forecast in June 1988.”

When I first saw your planet I thought maybe it was supposed to be the earth after global warming took its toll.

LOL! No, it's not supposed to be the Earth.

As a Star Trek fan I have to ask...

would that be a Class M planet?

Stan,

As a Star Trek fan I have to ask...

LOL! I, too, like Star Trek, though my favorite has always been the original series. I did not envision that planet as being inhabited, but who knows? I'll have to do a scan for life forms to find out for sure.

Oh, and for the sake of any non-Trekkies that may be reading this, here is the definition of a "Class M" planet:

"Class M, or "Terrestrial", planets are the most commonly visited planets in the Star Trek series. They are named after the Vulcan term "Minshara" class. They have atmospheres comprised of nitrogen and oxygen but most importantly, they have an abundance of liquid water necessary for carbon-based life to exist. Life is almost always present and is often flourishing as extensive plant and animal life. Usually, a sentient race is also present. Earth is a textbook example of a Class M world. Other worlds in the series are mentioned as being Class M planets, such as Vulcan, Cardassia Prime, Risa (initially seen in the Next Generation episode "Captain's Holiday"), Bajor, Betazed, Romulus, and Qo'noS."

James Hansen in his own words [Nature Sep 05 2008]:
This week, James Hansen was in London, UK, to testify on behalf of activists who defaced a coal-fired power station in Kent. Geoff Brumfiel caught up with Hansen at a London hotel to find out what has got him all hot and bothered.
Why did you come to testify?
Nothing could be more central to the problem we face with global climate change. If you look at the size of the oil, gas and coal reservoirs you'll see that the oil and gas have enough CO2 to bring us up to a dangerous level of greenhouse gases in the atmosphere.
There's a potential to solve that problem if we phase out coal. If we were to have a moratorium on coal-fired power plants within the next few years, and then phase out the existing ones between 2010 and 2030, then CO2 would peak at something between 400 and 425 parts per million. That leaves a difficult problem, but one that you can solve.
Do you think that leaders like UK Prime Minister Gordon Brown have lived up to their promises on climate change?
It depends on whether they will have a moratorium on coal-fired power. I think that the greenest leaders, like German chancellor Angela Merkel and Prime Minister Brown, are saying the right words. But if you look at their actions, emissions are continuing to increase. All of these countries and the United States are planning to build more coal-fired power plants. And if you build more coal-fired power plants, then it is not possible to achieve the goals that they say they are committed to. It's a really simple argument and yet they won't face up to it.
So do you think that these activists were justified in doing what they did?
The activists drawing attention to the issue seems to me as justified. You should try to do things through the democratic process, but we really are getting to an emergency situation. We can't continue to build more coal-fired power plants that do not capture CO2 if we hope to solve the problem.
We need to get energy from somewhere. So if we're not getting it from coal, then where?
The first thing we should do is focus on energy efficiency. The fact that utilities make more money by selling more energy is a big problem. We have to change those rules. Then there is renewable energy — in order to be able to fully exploit renewable energy, we need better electric grids. So those should be the first things, but I think that we also need to look at next-generation nuclear power.
Some have said you are hypocritical for flying all the way from the US to the UK just to testify. How do you respond?
I like to travel as little as possible, not only because it uses less CO2 but because I prefer to do science. But sometimes there are things which are sufficiently important that I think it makes sense.
What do you think the roll of the scientist should be in the broader societal debate on climate change?
I think it would be irresponsible not to speak out. There is a clear gap between what is understood by the relevant scientific community and what is known by the public, and we have to try and close that gap. If we don't do something in the very near future, we're going to create a situation for our children and grandchildren that is out of control.

Climate of Fear
Global-warming alarmists intimidate dissenting scientists into silence.

by RICHARD LINDZEN
Wednesday, April 12, 2006 12:01 A.M. EDT

There have been repeated claims that this past year's hurricane activity was another sign of human-induced climate change. Everything from the heat wave in Paris to heavy snows in Buffalo has been blamed on people burning gasoline to fuel their cars, and coal and natural gas to heat, cool and electrify their homes. Yet how can a barely discernible, one-degree increase in the recorded global mean temperature since the late 19th century possibly gain public acceptance as the source of recent weather catastrophes? And how can it translate into unlikely claims about future catastrophes?

The answer has much to do with misunderstanding the science of climate, plus a willingness to debase climate science into a triangle of alarmism. Ambiguous scientific statements about climate are hyped by those with a vested interest in alarm, thus raising the political stakes for policy makers who provide funds for more science research to feed more alarm to increase the political stakes. After all, who puts money into science--whether for AIDS, or space, or climate--where there is nothing really alarming? Indeed, the success of climate alarmism can be counted in the increased federal spending on climate research from a few hundred million dollars pre-1990 to $1.7 billion today. It can also be seen in heightened spending on solar, wind, hydrogen, ethanol and clean coal technologies, as well as on other energy-investment decisions.

But there is a more sinister side to this feeding frenzy. Scientists who dissent from the alarmism have seen their grant funds disappear, their work derided, and themselves libeled as industry stooges, scientific hacks or worse. Consequently, lies about climate change gain credence even when they fly in the face of the science that supposedly is their basis.

To understand the misconceptions perpetuated about climate science and the climate of intimidation, one needs to grasp some of the complex underlying scientific issues. First, let's start where there is agreement. The public, press and policy makers have been repeatedly told that three claims have widespread scientific support: Global temperature has risen about a degree since the late 19th century; levels of CO2 in the atmosphere have increased by about 30% over the same period; and CO2 should contribute to future warming. These claims are true. However, what the public fails to grasp is that the claims neither constitute support for alarm nor establish man's responsibility for the small amount of warming that has occurred. In fact, those who make the most outlandish claims of alarm are actually demonstrating skepticism of the very science they say supports them. It isn't just that the alarmists are trumpeting model results that we know must be wrong. It is that they are trumpeting catastrophes that couldn't happen even if the models were right as justifying costly policies to try to prevent global warming.

If the models are correct, global warming reduces the temperature differences between the poles and the equator. When you have less difference in temperature, you have less excitation of extratropical storms, not more. And, in fact, model runs support this conclusion. Alarmists have drawn some support for increased claims of tropical storminess from a casual claim by Sir John Houghton of the U.N.'s Intergovernmental Panel on Climate Change (IPCC) that a warmer world would have more evaporation, with latent heat providing more energy for disturbances. The problem with this is that the ability of evaporation to drive tropical storms relies not only on temperature but humidity as well, and calls for drier, less humid air. Claims for starkly higher temperatures are based upon there being more humidity, not less--hardly a case for more storminess with global warming.

So how is it that we don't have more scientists speaking up about this junk science? It's my belief that many scientists have been cowed not merely by money but by fear. An example: Earlier this year, Texas Rep. Joe Barton issued letters to paleoclimatologist Michael Mann and some of his co-authors seeking the details behind a taxpayer-funded analysis that claimed the 1990s were likely the warmest decade and 1998 the warmest year in the last millennium. Mr. Barton's concern was based on the fact that the IPCC had singled out Mr. Mann's work as a means to encourage policy makers to take action. And they did so before his work could be replicated and tested--a task made difficult because Mr. Mann, a key IPCC author, had refused to release the details for analysis. The scientific community's defense of Mr. Mann was, nonetheless, immediate and harsh. The president of the National Academy of Sciences--as well as the American Meteorological Society and the American Geophysical Union--formally protested, saying that Rep. Barton's singling out of a scientist's work smacked of intimidation.

All of which starkly contrasts to the silence of the scientific community when anti-alarmists were in the crosshairs of then-Sen. Al Gore. In 1992, he ran two congressional hearings during which he tried to bully dissenting scientists, including myself, into changing our views and supporting his climate alarmism. Nor did the scientific community complain when Mr. Gore, as vice president, tried to enlist Ted Koppel in a witch hunt to discredit anti-alarmist scientists--a request that Mr. Koppel deemed publicly inappropriate. And they were mum when subsequent articles and books by Ross Gelbspan libelously labeled scientists who differed with Mr. Gore as stooges of the fossil-fuel industry.

Sadly, this is only the tip of a non-melting iceberg. In Europe, Henk Tennekes was dismissed as research director of the Royal Dutch Meteorological Society after questioning the scientific underpinnings of global warming. Aksel Winn-Nielsen, former director of the U.N.'s World Meteorological Organization, was tarred by Bert Bolin, first head of the IPCC, as a tool of the coal industry for questioning climate alarmism. Respected Italian professors Alfonso Sutera and Antonio Speranza disappeared from the debate in 1991, apparently losing climate-research funding for raising questions.

And then there are the peculiar standards in place in scientific journals for articles submitted by those who raise questions about accepted climate wisdom. At Science and Nature, such papers are commonly refused without review as being without interest. However, even when such papers are published, standards shift. When I, with some colleagues at NASA, attempted to determine how clouds behave under varying temperatures, we discovered what we called an "Iris Effect," wherein upper-level cirrus clouds contracted with increased temperature, providing a very strong negative climate feedback sufficient to greatly reduce the response to increasing CO2. Normally, criticism of papers appears in the form of letters to the journal to which the original authors can respond immediately. However, in this case (and others) a flurry of hastily prepared papers appeared, claiming errors in our study, with our responses delayed months and longer. The delay permitted our paper to be commonly referred to as "discredited." Indeed, there is a strange reluctance to actually find out how climate really behaves. In 2003, when the draft of the U.S. National Climate Plan urged a high priority for improving our knowledge of climate sensitivity, the National Research Council instead urged support to look at the impacts of the warming--not whether it would actually happen.

Alarm rather than genuine scientific curiosity, it appears, is essential to maintaining funding. And only the most senior scientists today can stand up against this alarmist gale, and defy the iron triangle of climate scientists, advocates and policymakers.

Global Warming: The Cold, Hard Facts?

By Timothy Ball

Monday, February 5, 2007

Global Warming, as we think we know it, doesn't exist. And I am not the only one trying to make people open up their eyes and see the truth. But few listen, despite the fact that I was one of the first Canadian Ph.Ds. in Climatology and I have an extensive background in climatology, especially the reconstruction of past climates and the impact of climate change on human history and the human condition. Few listen, even though I have a Ph.D, (Doctor of Science) from the University of London, England and was a climatology professor at the University of Winnipeg. For some reason (actually for many), the World is not listening. Here is why.

What would happen if tomorrow we were told that, after all, the Earth is flat? It would probably be the most important piece of news in the media and would generate a lot of debate. So why is it that when scientists who have studied the Global Warming phenomenon for years say that humans are not the cause nobody listens? Why does no one acknowledge that the Emperor has no clothes on?

Believe it or not, Global Warming is not due to human contribution of Carbon Dioxide (CO2). This in fact is the greatest deception in the history of science. We are wasting time, energy and trillions of dollars while creating unnecessary fear and consternation over an issue with no scientific justification. For example, Environment Canada brags about spending $3.7 billion in the last five years dealing with climate change almost all on propaganda trying to defend an indefensible scientific position while at the same time closing weather stations and failing to meet legislated pollution targets.

No sensible person seeks conflict, especially with governments, but if we don't pursue the truth, we are lost as individuals and as a society. That is why I insist on saying that there is no evidence that we are, or could ever cause global climate change. And, recently, Yuri A. Izrael, Vice President of the United Nations sponsored Intergovernmental Panel on Climate Change (IPCC) confirmed this statement. So how has the world come to believe that something is wrong?

Maybe for the same reason we believed, 30 years ago, that global cooling was the biggest threat: a matter of faith. "It is a cold fact: the Global Cooling presents humankind with the most important social, political, and adaptive challenge we have had to deal with for ten thousand years. Your stake in the decisions we make concerning it is of ultimate importance; the survival of ourselves, our children, our species," wrote Lowell Ponte in 1976.

I was as opposed to the threats of impending doom global cooling engendered as I am to the threats made about Global Warming. Let me stress I am not denying the phenomenon has occurred. The world has warmed since 1680, the nadir of a cool period called the Little Ice Age (LIA) that has generally continued to the present. These climate changes are well within natural variability and explained quite easily by changes in the sun. But there is nothing unusual going on.

Since I obtained my doctorate in climatology from the University of London, Queen Mary College, England my career has spanned two climate cycles. Temperatures declined from 1940 to 1980 and in the early 1970's global cooling became the consensus. This proves that consensus is not a scientific fact. By the 1990's temperatures appeared to have reversed and Global Warming became the consensus. It appears I'll witness another cycle before retiring, as the major mechanisms and the global temperature trends now indicate a cooling.

No doubt passive acceptance yields less stress, fewer personal attacks and makes career progress easier. What I have experienced in my personal life during the last years makes me understand why most people choose not to speak out; job security and fear of reprisals. Even in University, where free speech and challenge to prevailing wisdoms are supposedly encouraged, academics remain silent.

I once received a three page letter that my lawyer defined as libelous, from an academic colleague, saying I had no right to say what I was saying, especially in public lectures. Sadly, my experience is that universities are the most dogmatic and oppressive places in our society. This becomes progressively worse as they receive more and more funding from governments that demand a particular viewpoint.

In another instance, I was accused by Canadian environmentalist David Suzuki of being paid by oil companies. That is a lie. Apparently he thinks if the fossil fuel companies pay you have an agenda. So if Greenpeace, Sierra Club or governments pay there is no agenda and only truth and enlightenment?

Personal attacks are difficult and shouldn't occur in a debate in a civilized society. I can only consider them from what they imply. They usually indicate a person or group is losing the debate. In this case, they also indicate how political the entire Global Warming debate has become. Both underline the lack of or even contradictory nature of the evidence.

I am not alone in this journey against the prevalent myth. Several well-known names have also raised their voices. Michael Crichton, the scientist, writer and filmmaker is one of them. In his latest book, "State of Fear" he takes time to explain, often in surprising detail, the flawed science behind Global Warming and other imagined environmental crises.

Another cry in the wilderness is Richard Lindzen's. He is an atmospheric physicist and a professor of meteorology at MIT, renowned for his research in dynamic meteorology - especially atmospheric waves. He is also a member of the National Academy of Sciences and has held positions at the University of Chicago, Harvard University and MIT. Linzen frequently speaks out against the notion that significant Global Warming is caused by humans. Yet nobody seems to listen.

I think it may be because most people don't understand the scientific method which Thomas Kuhn so skilfully and briefly set out in his book "The Structure of Scientific Revolutions." A scientist makes certain assumptions and then produces a theory which is only as valid as the assumptions. The theory of Global Warming assumes that CO2 is an atmospheric greenhouse gas and as it increases temperatures rise. It was then theorized that since humans were producing more CO2 than before, the temperature would inevitably rise. The theory was accepted before testing had started, and effectively became a law.

As Lindzen said many years ago: "the consensus was reached before the research had even begun." Now, any scientist who dares to question the prevailing wisdom is marginalized and called a skeptic, when in fact they are simply being good scientists. This has reached frightening levels with these scientists now being called climate change denier with all the holocaust connotations of that word. The normal scientific method is effectively being thwarted.

Meanwhile, politicians are being listened to, even though most of them have no knowledge or understanding of science, especially the science of climate and climate change. Hence, they are in no position to question a policy on climate change when it threatens the entire planet. Moreover, using fear and creating hysteria makes it very difficult to make calm rational decisions about issues needing attention.

Until you have challenged the prevailing wisdom you have no idea how nasty people can be. Until you have re-examined any issue in an attempt to find out all the information, you cannot know how much misinformation exists in the supposed age of information.

I was greatly influenced several years ago by Aaron Wildavsky's book "Yes, but is it true?" The author taught political science at a New York University and realized how science was being influenced by and apparently misused by politics. He gave his graduate students an assignment to pursue the science behind a policy generated by a highly publicized environmental concern. To his and their surprise they found there was little scientific evidence, consensus and justification for the policy. You only realize the extent to which Wildavsky's findings occur when you ask the question he posed. Wildavsky's students did it in the safety of academia and with the excuse that it was an assignment. I have learned it is a difficult question to ask in the real world, however I firmly believe it is the most important question to ask if we are to advance in the right direction.
