Running Says More Should Move to Acceptance Stage
Nobel Winner Lectures on ‘The Five Stages of Climate Grief’

Since learning last month that he was a co-winner of the 2007 Nobel Peace Prize, University of Montana professor Steve Running has received many letters and emails regarding his win, and not all have been congratulatory.
The hate mail, Running said in a lecture at the UM campus Monday evening, has come from those going through the “anger” phase of what Running calls “The Five Stages of Climate Grief.”
Running, a professor in UM’s College of Forestry and Conservation, won the Nobel for his work as one of the leading authors of the fourth assessment report issued by the Intergovernmental Panel on Climate Change (IPCC).
The IPCC was formed in 1988 by two United Nations organizations. Scientists from around the world were chosen to analyze a huge amount of data on climate change and compile it into reports. Each of the panel’s reports, particularly the latest one, has emphasized three major points: the Earth is getting warmer; it’s getting warmer quickly; and it’s getting warmer because of human activity.
In Monday’s speech Running adapted Elisabeth Kubler-Ross’s “Five Stages of Grief” model to apply to climate change. Running said there are those in denial (the earth isn’t getting warmer, and if it is it isn’t our fault); those who are angry; those who are bargaining (“It was always too cold in Montana, anyway,” Running quipped); those who are depressed; and those who have come to accept climate change as a fact.
Running would like to see more people moving to the acceptance or, as he called it, the “let’s get to work” phase.
After briefly explaining the difference between climate and weather – weather is delivered directly from the atmosphere; climate is weather trends over a long period of time – Running provided many grim examples of how climate change will likely affect Montana if warming trends continue as predicted. All the glaciers in Glacier Park may be gone by 2020, Running said. In 50 years Missoula won’t receive any snowfall. The fire season will continue to get longer and more intense. Snowpacks at high altitudes will continue to diminish.
The worst case climate scenario, which would occur if world carbon emissions keep rising at their current annual rate, is so bad, Running said, that climate scientists aren’t even sure if the Earth could maintain a functioning biosphere at that temperature. To avoid this fate, Running said, drastic measures must be taken. According to Running, the work of climate scientists is largely done.
“[The problem of global warming] is becoming a political science question and not a climate science question,” Running said. “We need politicians willing to admit we’re in a big pickle.”
Running also said American society needs to be “willing to do a little sacrificing.”
Though he knows it won’t be pretty, and certainly not popular, Running believes that the government must begin drastically increasing the taxes on oil. Running would like to see the price of gasoline rise a dollar a gallon each year for the next five. Running said that he isn’t a big fan of cap and trade, a policy of taxation that would target corporate polluters.
This taxation proposal, Running said, would provide serious incentive to create new energy technologies.
“If [a tax] affected everybody,” Running said, “it would get everybody’s attention.”
Running also emphasized that to help slow global warming we must come up with innovative energy solutions and leave coal in the ground.
Though the picture he painted was certainly bleak, Running did offer a few words of encouragement. In the 1970’s, Running said, nobody could have possibly imagined a gadget as sophisticated as the iPhone. Advances in communications technology in recent years have been almost unfathomable, Running said.
“[Think] what we did for communications technology,” Running said. “We have to do the same thing for energy for the next 40 years.”

Solution: taxes
FAIL
OH SNAP
There is NO global warming. Check out the article above. The Left is trying to punish everybody who can afford a big, fast, fancy (gas guzzling) car. They want us to live in huts and sing Kumbayah! Get a clue folks!
Far too many very qualified "deniers" remain for this question to be put to bed. I'm suspicious of any scientist who choses not to continue to learn. Clean the air...yep! Develop alternative fuels...yep! Dump vast monies into a fix for a problem that is yet to be clearly defined...nope!
Climate Change is ongoing. The level of human contribution is an open question.
Lastly, the Nobel Peace Prize no longer represents it's intended purpose - just as the UN does not represent its created purpose. Instead, the Nobel Peace Prize is doled out for political reasons (as the fact that not one, but two received the "prize" for work in global warming) while deserving folks who worked with poor children in poor countries, bringing them to health are sorely overlooked. Why? Probably because there's no money in children, but there is money in taxing emissions.
Great.

Particularly of interest to "No names, please" would be the article about the ice age predicted in the 70s (http://www.skepticalscience.com/ice-age-predictions-in-1970s.htm).
==================================
======================
Tip 1. Never underestimate the resourceful nature of mankind when presented with a real problem.
Tip 2. Remember the Club of Rome outcome.
Tip 3. Read Malthus.
Tip 4. Read "The Population Bomb" by Paul R. Ehrlich 1968
Tip 5. Don't read Al Gore, he's often wrong and knows it.
climateaudit.org for the skeptically minded.
==============================
And we got here by imposing strict government regulation, bureaucracy-guided research and 1000% taxes on the communication industry, right? Party lines make much more efficient use of the resource than wasteful private lines that are not fully utilized. Or better yet, just have one phone per city - a "responsible communication" advocate should have no problem walking / biking 3 miles to city hall, on a government-mandated schedule, to make or receive previously-scheduled phone calls.
The iPhone wasn't developed through a government program, it was the response of a company producing what people wanted. People will pay a premium for it now - in another couple years all the features of the iPhone will be standard commodity offerings from many vendors.
Some people are willing to pay a premium to drive a hybrid car, and as they fund the early development, more efficient, less expensive versions come to market. When driving a hydrogen-powered car becomes an affordable alternative, environmentally minded people will switch, followed by the general public when it becomes cheaper than petro power.
If the government gets involved at all (which should be with great caution), it should be with positive incentives rather than punitive measures. Even that can go awry, as with the Ethanol debacle of mismanagement, greed, and unintended consequences. If the activists succeed in tripling our transportation costs, the economy will collapse and there won't be anyone who can afford to do anything about carbon emissions.
If people choose to remain blind to the human impact on the ecosystem, they may be lucky enough to finish out there time on this planet before reality smacks them in the face (and I say “choose” because that is exactly what it is). But it sure is one heck of a way to tell your kids you love them. “Hey kids, you’ll get used to the gas masks and having to be completely covered from head to toe whenever you go outside/above ground (why would you want to though?). And the water rationing won’t be so bad, and the artificial nutrients are getting better tasting every year. Here are some nice pictures of those forests and lakes I used to talk about. That’s right, rivers used to flow, and water outside actually used to be clear (thought not clean for quite some time). No, no, no, humans had nothing to do with this at all; it was just the natural course of things. Have a wonderful life”.
Wake up people. If not for yourselves, than for the legacy that is in danger of being snuffed out.
The latest science on the 'chicken-egg' conundrum shows, from examining ice core samples, that the earth began to warm before the rise in CO2. See: http://www.eurekalert.org/pub_releases/2007-09/uosc-cdd092507.php This is Dr. Christy's point that there are so many things yet to learn about climate change.
===================================
1) CO2 and CH4 are heat trapping gasses;
2) There is an ever increasing amount of CO2 in the Earth's atmosphere from anthropogenic use of NON-RENEWABLE fossil fuels.
Running's and the IPCC's language may seem overstated and alarmist, but that doesn't mean it's untrue.
Congratulations on the well deserved recognition and keep up the good work, dudes.
#1: There are indeed people who are in complete denial about this issue, wanting to believe so badly that there isn't an issue, that they're willing to scrape for every piece of false and superfluous data they can. But what do you expect when so many are flat-earth/creationists?
#2: The above said, Dr. Running's idea that the planet is necessarily going to repeat another Paleocene-Eocene thermal maximum is highly speculative at best. There simply isn't the data to make that kind of prediction. Further, certain technologies, such as mixing deep and upper layers of ocean water, could create a major impact on global climate without much cost.
#3: Regardless of the global warming "debate" (denial), the issue of energy is going to be one that dominates the lives of our children and grandchildren. We live in an age of cheap food derived from mechanized agriculture that runs on fossil fuels. Even if global warming wasn't an issue, that simply can't last. One day, 10 years or 100 in the future, dwindling gas will cost the equivalent of $12.00 a gallon (where it's cheap). What will food cost then? How will it get trucked to market? Now is the time to address those issues are - not after the world population doubles and we're faced with mass starvation.
#4: Taxes raising may be bad; tax shifting is not. If you raise taxes on gas (bad) and use the money to cut taxes on good things we presently tax (like employment), you get less bad things, and more good things happening. In other words, this doesn't have to be a partisan issue. (It may still be because Republicans appear to have been taken over by the insane wing of their party, but that's not Al Gore's fault.)
As someone else mentioned, co-Nobel winner John Christy is also at variance with the IPCC's conclusions on Global warming. Bottom line the IPCC is a political organization. The final reports are written by politicians and bureaucrats, read the IPCC Guidlines and procedures. For those who think there is no debate try reading the actual comments by IPCC reviewers: http://ipcc-wg1.ucar.edu/wg1/Comments/wg1-commentFrameset.html
Ad hominem attacks have nothing to do with science and neither further scientific discourse nor promote the validity of the speaker's point of view.
Bottom line the evidence CO2 as THE driving force for climate change is not there. In fact it follows, by some 700-800 years, warming not precedes it, which means, for those who have conceptual difficulties, that it can't be a cause.
Finally, and this is critical to those who advocate the primacy of science - consensus is a political concept, not a scientific one. One study can disprove a plethora of studies to the contrary.
WHAT'S SO GOOD ABOUT THE WAY WE LIVE NOW?
Our culture is certifiably insane. The foundation of our way of life is violence. We're as free as cattle at an auction, complete with prods. And, like domesticated versus their still wild brethren, we're becoming less intelligent the farther along the road of "progress" we get.
Anyone worried about losing their automobile is probably too far gone to even WANT to know what real freedom is.
I'd bet that neither Rupert nor lone voice have ever carried water for a bath, to flush, to drink, etc. I'll bet they have never had to go out and use the outhouse when it was -10 or 20. They might have to find out if we keep using up all of our water though and have to buy it in bottles. Bet they do not remember when the phone was put in, nor when the electric was. If they had ever done any of these things they would know what is so great abouot how we live now.
But I have done all the things you mention here, and have lived in many places where there was no electricity ( a big town on the Amazon, for one, dozens of saw camps for others) and I have to tell you that the lack of those things does not mean your life is ruined. In fact, it is the terror of losing those enormous comforts that is, in my opinion, most ruinous to freedom and happiness. You've had a long, hard working life, from what I understand from your posts-- you have seen alot. Now, I ask you, are all these folks who can't get ten feet away from the thermostat, who have to have the bathroom at 75 degrees or the day is wrecked, are they happier? Are they free?
Isn't it possible that all those comforts you mention are making us all slaves of an energy economy over which we have no control? Slaves of whoever owns the power sources and can threaten to turn them off? Better not complain about the pollution from the coal plant, pal, or we'll cut your computer off. Don't like clearcuts?
Wipe your *** with a spotted owl! yes, we are builiding ten thousands miles of road, walled with knapweed, to our new gas wells on public land, but you like a hot shower, don't you?
I think what rupert and lone voice were saying is that if you look around, the way we are living now really does look unsustainable. I think they are asking whether, given the realities of the day, all of these comforts are really worth the cost of everybody's future.
The fact is we ALL are using our resources and despite the sneering aboout cutting off the electric, etc you use it too even while you bereate the producers. Once more, the problem is not the producer, it is the consumer, and it seems to me that those that beller the most about what others use are themselves even bigger users.
If you want to cut consumption, lead by example, don't try to force the rest of us to give up small pleasures so there is more for you, and that seems to be the basic premise of enviros.
Issues regarding energy independence or whether or not we are living a decadent lifestyle are irrelevant to the discussion.
My feeling is that gw typifies the whole environmental movement of control of other folks for the sake of control itself. This time there is no credible excuse they can make that it is necessary for everyone except themselves to live a very sparse lifestyle. If their lavish lifestyles are not a problem neither is anyone else's, nor is production of the fuel and food we need a problem.
But many people are trying very hard to figure out how to use those resources more efficiently and less destructively. I truly cannot understand why you- a person of obvious intelligence- would cast your lot with, and make your arguments for, those who deny that we can do better.
Especially when most of those who deny that we can do better are doing so because they want to keep making record profits from the current unsustainable energy equation.
I don't know anything about global warming except that enough people will argue over its cause that nothing will ever be done to address it. I just know that it is getting warmer and drier every year, based on data from the weather services and my own observation. For me and my family, it's more a question of how to live well in the new climate that is developing.
But it is fascinating-utterly fascinating-- to me that a large group of educated and affluent people would seize upon the questions over the causes of global warming, to argue forcefully that we should continue to burn coal, drive inefficient vehicles, heat uninsulated megahomes with natural gas, and pay billions to oil-rich Islamic jihadis to fuel the most inefficient transportation system ever known to man.
That (and I am not "sneering") is the dangedest, jaw droppingest, most baffling single thing I have ever encountered. I'd give a lot to understand it.
I don't know that anyone is advocating all of the use you just mentioned, but the fact remains, so called enviros are using the most while trying to insist the rest of us freeze to death. Those who produce fuel, food, and housing are filling a need.
Someone mentioned the other day that my other vehicle is a deisel truck and it has a camper. I have owned it for 11 1/2 years and I have never and will never use the 46,000 gallons of diesel that is laying on the bottom of the ocean in that cruise ship for enviros checking the global warming of Antarctica.
What youu say doesn't save anything, what you do is what matters. No matter what you call fuel producers, it is you that keeps them looking for ever more fuel. Again, enviros do not understand how they should be impacted by any of their big ideas and plans, but if you truly believe that global warming is man casued that is exactly what you yourself would do.
How does one address a perceived issue without knowing its cause? If as many suspect, CO2 is not the driving force for the warming climate, then why must we focus on CO2? If the warming climate is primarily driven by natural cyclical factors, which is most likely, then simply spending time, effort and money on adapting to the changing climate is the most intelligent thing to do. Even if every country, every man woman and child in the world adhered to the Kyoto document the impact on the temperature would be on the order of 0.05C over the next 100 years. The estimated increase in our temperature over the past 100 years is only 0.6C and that is just barely within the margin of error (+/- 0.7C).
The climate on this planet has always changed. It has been far warmer than it currently is. More importantly, it has been far colder, for far longer periods of time than it is today. CO2 in the atmosphere has been far greater than it is today as well as far less. Sticking a wet finger in the air and saying, "Gee it's getting warmer. Something must be done." is hardly scientific proof that something needs to be done. Nor are the computer models that predict dire disaster yet can't explain why things are not playing out according to their predictions.
The New Party in the UK is anything but conservative.

In order for the film to be shown, the Government must first amend their Guidance Notes to Teachers to make clear that 1.) The Film is a political work and promotes only one side of the argument. 2.) If teachers present the Film without making this plain they may be in breach of section 406 of the Education Act 1996 and guilty of political indoctrination. 3.) Nine inaccuracies have to be specifically drawn to the attention of school children.
The inaccuracies are:
-The film claims that melting snows on Mount Kilimanjaro evidence global warming. The Government’s expert was forced to concede that this is not correct.
-The film suggests that evidence from ice cores proves that rising CO2 causes temperature increases over 650,000 years. The Court found that the film was misleading: over that period the rises in CO2 lagged behind the temperature rises by 800-2000 years.
-The film uses emotive images of Hurricane Katrina and suggests that this has been caused by global warming. The Government’s expert had to accept that it was “not possible” to attribute one-off events to global warming.
-The film shows the drying up of Lake Chad and claims that this was caused by global warming. The Government’s expert had to accept that this was not the case.
-The film claims that a study showed that polar bears had drowned due to disappearing arctic ice. It turned out that Mr Gore had misread the study: in fact four polar bears drowned and this was because of a particularly violent storm.
-The film threatens that global warming could stop the Gulf Stream throwing Europe into an ice age: the Claimant’s evidence was that this was a scientific impossibility.
-The film blames global warming for species losses including coral reef bleaching. The Government could not find any evidence to support this claim.
-The film suggests that sea levels could rise by 7m causing the displacement of millions of people. In fact the evidence is that sea levels are expected to rise by about 40cm over the next hundred years and that there is no such threat of massive migration.
-The film claims that rising sea levels has caused the evacuation of certain Pacific islands to New Zealand. The Government are unable to substantiate this and the Court observed that this appears to be a false claim.
-Not all of the inaccuracies in the film were fully considered by the court as the judge requested a sample on which to consider the case. Professor Carter's witness statement (reproduced below) lists 20 inaccuracies in the film.

As things are beginning to come to life again in the uranium fields, I do believe that more and more the realization that nuclear power may be necessary is dawning.
The French has an extremely successful nuclear power industry and it has been in place for nearly 30 years. It is mind boggling to think that the hide bound French can actually do something like that better than we can.
There are more people killed every year as a result of the use of coal in energy production than have been killed in the production of nuclear power over its history. And this would include Chernobyl, which everyone, including the Soviets, knew was a garbage design.
We will not reach be able to replace current energy consumption, even at a drastically reduced rate, with wind, solar, geothermal, biofuel energy prodcution. It is not possible unless there is an enormous technological breakthrough that somehow changes the laws of physics.
And puhlease do not start yammering about giving up this thing or that to save energy. You could not give up enough to reduce demand to a level where those forms of energy would suffice.
You're dependent and scared. I'm dependent and pissed off about it and doing what I can while living in a system that has (consciously) taken as many options off the table that it can. One goal of this system is to make EVERYONE in the world dependent on it. And, obviously, it has largely succeeded.
But it really doesn't matter because unsustainable means unsustainable. Our present lifestyle will collapse - with or without those mean environmentalists trying to get you to stop being pigs and wise up. Maybe you believe technology will bail us out time and time again as nonrenewable resources dry up, disappear and are burnt. Of course, technology is what got us here in the first place, and is what keeps us dependent.
Banzai!
I've never seen radio active light out there.
By the way the family goes back to the point where my great great granparents put their names on Independence Rock in 1864. Their offspring only lived into their 90s as much of my family has.
And let’s not forget Chernobyl. We are far from perfect, and there has been nothing that humans have made that has not at one time or another shown to be flawed. And that is not factoring in the curves that Mother Nature and the geological instability of the earth can throw at us. When you play Russian roulette long enough, sooner or later, the gun goes off. The only problem with nuclear, is that the gun continues to go off for a long, long time.
Progress is obviously a subjective term. Most peoples of the world wouldn't list insanity and oppression as a symptom of progress. Asking when anybody was independent of progress is like asking if anybody has ever been independent of what is and what exists in someone's delusional mind. Certainly many people have existed independent of what you call 'progress.' Of course, 300 million of us can't shoot big game animals "for a living." That's the point.
I don't really care whether you're scared or not. And not much depends on whether you're scared or not. Stay alive long enough, or look down upon your grandchildren or their grandchildren, and probably you or they will have the chance to throw themselves under a horse and rider.
One of my daughters has been sick for years and Doctors diagnosed her with everything but what she had--thyroid cancer.
She called me last year and asked if she had a lot of x-rays as a child and when I told her she had never had an x-ray at all she was shocked--and then she told me that the endocrinologist had told her that her form of cancer could be traced back to high radiation exposure BEFORE the age of 10. She was born in 1961 and we lived S.E. of Denver. Her Doctor said her form of cancer was seen in the children of the Chernobyl incident.
So as far as I am concerned--nuclear is not an option for our energy issues.
There is a simple passive solar window box that every homeowner could make with a tiny investment and guess what-- it costs about $100.
But then I've been trying to solve problems for years.
You guys need to go back and read Steve Reddings post again.
Have you had a radon removal system installed in your home as I believe radon is prevalent in your area. Ionizing radiation, radon being one of those, have been directly linked to thyroid cancer. However, radon is normally associated with lung cancer.
No one else in my family has had cancer except one aunt--heart problems but not cancer ---and since I know what caused these two incidents I will fight for energy solutions that do not pollute
We did test for radon years ago in Colo.--- which is a natural occurring gas--my concern is for the man made illnesses and thyroid cancer is one of them-- It is interesting to note that the Univ. of Colo treats so many thyroid cancer patients that it seems to scream cluster--
It all goes back to our poor stewardship of the natural world--we have to accept what we've done and start cleaning it up--
The International Atomic Energy Agency put out a publication 'Sustainable Development & Nuclear Power' addressing nuclear power issues. It is worth a read. http://www.iaea.org/Publications/Booklets/Development/index.html
Nuclear power can and has been used quite safely. As I said earlier, the French have managed it quite well for a very long time. That we have not is a matter of political will, not science.
Going back to the original premise of this article. Does it occur to no one that, perhaps, the alarmists are the ones in denial. Why else would they ignore science which presents a different point of view. More importantly why do they consistently fall to ad hominem attacks without ever addressing the science. Could it be that they have also fallen for their Pygmalian, their computer models which are so consistently at odds with observed climate, which have never successfully recreated historical climates? These same models can not explain why Antarctica has continued to cool and build ice, after all this is "global" warming we are discussing. The "convenient" answer that some place will cool and some will warm is, well, too convenient.
The continuing growth of humanity and the collective desire for an upgraded lifestyle requires ever expanding energy requirements. Alternative energy sources such as wind and solar just will not meet these needs. The upgraded lifestyles usually equate to longer lives than were possible before. We will be faced with a choice to fulfill these expanding energy needs, either more carbon based or nuclear. Nothing else comes even close to addressing this demand. I believe as a society we will be far better off with NP then carbon emitting stacks. Another benefit of NP will be the power source for electrolysis to produce hydrogen for fuel cell vehicles. FCV's are where we will finally see a real improvement in air quality leading to less illness like cancers. Just my opinion.
I would first like to say that I do not buy into the Al Gore movie. I don’t accept everything Steve Running has stated. I do know, and from both of your comments, you do too, that carbon dioxide and methane are greenhouse gases. And there is no denying that there are untold tons of both in the air as a direct result of human energy production. I know that when you decrease the amount of plant life in an ecosystem, (deforestation), you also reduce how much CO2 can be absorbed. My point is that these and other factors have to have an effect. It seems that we mainly disagree with how much of an effect. I will go out on a limb and say that you may even be inclined to agree that if we continue on the present course, sooner or later, we will have to pay the piper. We live on a small rock with finite resources being utilized at a rate that cannot be sustained. And in doing so we are altering the chemical composition of our rock from the state that allowed us to thrive as the life forms we are. This just doesn’t seem like a very smart thing to do.
As far as nuclear energy goes, the problems are not just in the plants themselves, but in the byproducts. This stuff is deadly for tens, sometimes hundreds of thousands of years. If we came up with a completely clean nuclear power source today, what we have already produced will have to be dealt with for generations. As I stated earlier, I am not against nuclear power. I am against it in its current form. If we are not able to meet the growing energy needs at this time without increasing greenhouse emissions or using the current nuclear model, then maybe we need to find ways to lessen our energy needs until a safe, (not just for this generation), alternative can be found.
Because of nuclear weapons, we are already the only species on the planet that can be directly responsible for our own extinction. Our (the worlds) energy policies is just another way for us to accomplish this it will just take longer. Something needs to change. I would much rather be guilty of doing too much than too little to make the change. The former just means we inconvenienced ourselves more than was needed, the later…
As a side note I would just like to say that it is a pleasure debating this topic with the both of you. Batter up.
We ahve to face the fact that there simply have to be some compromises if we are going to have adequate. We are going to have to look at drilling rigs in oil fields, we are going to have to look at coal mines, wind mills on hill tops, etc. Oil and gas are where they are, the scenery does not matter, we cannot decide that drilling can occur in such and such a place with enviro blessing, it can and will only occur if there is oil/gas there.
Ultimately we are going to be forced to use nuclear, unless some new and unknown source of energy shows up.
How does one address a perceived issue without knowing its cause? If as many suspect, CO2 is not the driving force for the warming climate, then why must we focus on CO2?
I don't know where you get this information. Nearly every scientist studying global climate change agrees that CO2 is one of the prime drivers of this change.
If the warming climate is primarily driven by natural cyclical factors, which is most likely, then simply spending time, effort and money on adapting to the changing climate is the most intelligent thing to do.
Just because you claim that the current warming trend is due to natural cycles does not make it so. Certainly, previous instances of global climate change (prior to the industrial revolution) were due to natural cycles, but the present episode does not correlate with any such cycle. It does, however, strongly correlate with the growth of GHG concentrations in our atmosphere.
No doubt someone will point out the causality issue regarding natural cycles and how in the past the warming preceded increased CO2 by several centuries. What they fail to also acknowledge is how after the CO2 starts to increase, the warming trend intensifies due to a positive feedback situation.
In the natural carbon cycle, at the end of a cool period ("ice age"), natural cycles related to the Earth's orbital parameters (known as Milankovitch cycles) or to changes in solar output, start to increase the temperature of the planet. This leads to a decrease in the ability of the oceans to sink CO2 (the warmer it is, the less the oceans can absorb). As a result, the excess CO2 is outgassed by the oceans and returns to the atmosphere. Over time this intensifies the effects of the natural cycles by trapping additional heat in the atmosphere via the GH effect.
After several millenia, those natural cycles start to operate in the opposite direction, the planet starts to cool, more CO2 gets absorbed by the oceans, and a new ice age is the result. That is how the natural carbon cycle works.
What has been happening over the past 150 years (since the start of the industrial revolution) is that we have been releasing additional CO2 into the atmosphere in order to power our civilization. This has increased at an even greater rate over the past few decades, when the warming has grown even faster. As a result, we've bypassed the whole natural causality issue and are already in the rapid warming phase of the carbon cycle. If anything, pointing out that in previous instances warming preceded CO2 increases works to defeat the arguments of the GW denialists, since we are not operating under the condition of a natural event.
No doubt someone else will point out the "global cooling" fears of the 1970s. Perhaps they should learn something about global dimming and the role of aerosols in that discussion. Maybe the solution is that we should bring back CFCs :-).
The climate on this planet has always changed. It has been far warmer than it currently is. More importantly, it has been far colder, for far longer periods of time than it is today. CO2 in the atmosphere has been far greater than it is today as well as far less.
The current concentration of CO2 is closing in on 400 ppm, which is at least 33% higher than at any time in the past several hundred thousand years. There has been no evidence presented by anyone that it was ever higher than this in the more distant past. Try researching the works of NASA scientist James Hansen, one of the foremost authorities on global climate issues.
I also want to once again point out that Marion has reverted to her failed arguments concerning the current wintertime weather in her corner of the world. If that were the case, why did we have temperatures above 50F here in Boise yesterday? It's December, for crying out loud! And if you really don't like the chill in the air, perhaps you should consider becoming a snow bird and spend your winters in Arizona or somewhere warmer?
All that being said, as I have stated elsewhere, including on my own blog here at New West, I support an increase in commercial nuclear power as an alternative to the use of fossil fuels to power our society. I recognize that there are issues with this energy source, as there are with all of the options, but I view the threat of AGW to be far more serious than that posed by using more nuclear power.
I also support a greater reliance on renewable sources like wind, solar, hydro, geothermal, etc. However, until these sources can demonstrate an ability to supply a significant fraction of our total energy needs, nuclear is a viable option in my opinion.
When I read all of the articles about the glaciers melting and raising the sea level, none seem to address the increased evaporation from the heat.
Beyond the world of the IPCC there are also many other scientists who disagree with the CO2 as main driver thesis. John Christy of the University of Alabama (also a member of the IPCC) for one, Roy Spencer, whose recent studies on the impact of clouds and water vapor for another; Svensmark, William Grey, the list goes on. If you take the time to research you will also that there are many studies that take issue with the AGW premise. These are professional and peer reviewed study appearing in such journals as the Journal of Geophysical Letters, among others.
Judging any climate trends on a 300-400 year time scale is absurd. That is a gnat's blink of time in earth's natural history. The positive feedbacks you mention exist only in the much vaunted climate models. The same climate models which are incapable of "hindcasting" and must be constantly "tweaked" in order to come into line with observed climate.
Finally, you mention that CO2 has reached nearly 400ppm in our atmosphere, actually, it's 385ppm. Do you realize that if the models are correct, we should have experienced a much greater warming than we have in the past twenty years? Do you also realize that CO2 has a logrhythmic effect on climate? That is each subsequent molecule of CO2 has less impact than the preceeding ones?
You can listen to Hansen's arrogant and highly political pronouncements or you can actually study this issue.
