Back in the 80's and 90's, there was an overwhelming amount of information and scientific consensus that smoking can and does cause cancer.
Back in the 60’s it was known that smoking can cause cancer. It is not the cause it is a contributing factor. This is why it is so difficult to blame the cigarette companies for defending their product. If smoking were the cause of cancer then everyone that smoked would get cancer. This is not true and has not happened. It took 30 years just to get doctors to stop smoking. My girlfriend is an ICU nurse and I see the doctors standing outside the hospital building smoking as late as yesterday. It is a personal choice not like global warming where people are told they have no choice. There is no pollution industry to fight the information that is coming out. No one is running around trying to discredit the reports in order to support big pollution. What we have are scientists that disagree with each other. One side says man is the problem but has no proof, the other side says we don’t see any proof that man is the cause but we do have proof that the Sun is the cause. Give us proof and we will see where it leads.
What we see today is a reproduction of that same campaign. We have a multitude of 'think tank' groups that are politically and ideologically motivated to prove that climate change isn't caused by man. These are not skeptics, they are deniers, who will deny any information that goes against their ideological goals. In reality, most of the major scientific groups out there long ago linked our greenhouse gas emmissions to increased temperature. Long ago most major scientific groups did in fact reach a consensus- and no, consensus does not mean that 100% of everyone out there agrees. That happens rarely or never at all on most issues.
This is where I point again that you don’t get what I am pointing out to you. The IPCC report on climate change states that man’s contribution to global warming amounts to .05 of one degree over 100 years. You point to livescience.com as a place of credibility so I dug up a report from January on that same site that says the actual data conflicted with the models. In stead of 1.4 degree rise in temp they were only able to document a .4 degree rise in temp. Are you now going to tell me that the source for your information has been corrupted by politics? Somehow big oil slipped that one past peer review got it published and then reported on your website? The “deniers” as you call them point out that the methods of arriving at this huge number is flawed. Having read the report I came to the conclusion that I can live with .05 of a degree over the next hundred years as an average spread out over the entire planet. And if it is as flawed as the skeptics say it is then we are talking about .00021 of a degree over 100 years. Either way the amount is negligible. It does not matter who is right here because if we live that long we will not feel the difference either way.
In reference to James Hansen? I was illustrating that members of NASA have been stating that global warming is real, and most likely caused by man for years now with very little notice from government until recently.
In reference to Dr. Roy Spencer, he was a scientist at NASA, he disagrees with Dr. Hansen, I don’t know about Dr. Hansen but I do know that Dr. Spencer just finished testifying in front of the U.S. Senate yesterday when they wanted to know about global climate change. The worse thing anyone said about him that day was that he is the official climatologist for Rush Limbaugh. Since leaving NASA he is a full professor in some dinky little collage or university. His published papers have passed peer review, and he is highly respected in his community, and has not taken any money from big oil but has taken money from environmental groups. He has no political axe to grind that I or his opponents have been able to find. So you have two accredited scientists with different opinions of the same set of facts. I have not seen Dr. Hansen’s published work so I can’t comment on it. Care to tell me where I might find it?
No, I'm not ignoring it. I've read the links you've provided. They question the validity of previous testing methods and pose alternate hypothesis as to why the planet may be warming, which is great. But they do not disprove the theory that our industrial emmissions are contributing to the issue!
So if the methods of arriving at a conclusion are flawed would that not mean that the conclusion was flawed?
Here is an old joke they told in class when discussing scientific observation.
A scientist took a frog and set it on the table and yelled jump. The frog jumped. He picks up the frog cuts off its right front leg, and then sets it on the table again. Jump he yells. The frog jumps. He cuts off the left front leg and repeats the process. Taking copious notes as he goes. The frog still jumped so he cuts off the left hind leg and yells jump. The frog jumps. He cuts off the right hind leg and yells jump. The frog does not move. Based on scientific observation the scientist concluded that if you cut off the right hind leg the frog goes deaf. The point my professor was trying to make was that you can have all the facts but still come to the wrong conclusion.
In the case of global climate change you have a field of study that is flawed to begin with. No climatologist can accurately predict the weather more than three or four days in advance. To prove this watch your local news every day for seven days and write down the forecast for each day. Look at was predicted five six and seven days out and watch how that changes each day. Now you want to try to predict the weather conditions for the entire planet 100 years from now. If you read the IPCC report you will find they have a bunch of models and eight to ten scenarios for each model for each prediction. With that they take what they think is most likely to be accurate and write their report based on that.
Now I have shown you from livescience that people working purely on a scientific mode have found that the models were off by a full degree. This is independent confirmation the “deniers” were correct when they said the models are flawed. You ignored this information. All of what I posted on the flaw was based on published work that had passed peer review because that was your standard of proof. Or it was until the work you support was disproven then it did not matter that it was done by accredited scientists under peer review. It does not matter that authors of the report support global warming and published a finding of fact that contradicts their view. (As a scientist is supposed to do)
With proof of flawed data, models, and conclusions the work is invalid by scientific standards. The theory may still be valid but that body of work is not. I have read theories that I dismiss like the flat Earth society that publishes a bunch of papers each year, all subject to peer review. And if you will just discount math, physics, hydrodynamics, astrophysics, geometry and gravity then most of those theories have merit. There is a consensus among the flat earth community of scientists that the earth is flat.
To accept the IPCC’s fourth report you have to ignore little things like astrophysics, thermal dynamics, gravity, orbital mechanics, and the heat from the Sun and its effect on the Earth. Every single one of those things is part of our climate. Not to mention meteor strikes, volcanic eruptions, forest fires, and the list goes on. In the IPCC report only volcanoes are listed as a contributing factor, but excluded super volcanoes. Just so you know the last time a super volcano erupted man’s population dropped from tens of millions down to under 10 thousand. Earth is due for two such eruptions within the next 10 thousand years and we are about 300 years over due for one in America. All of this has to be ignored in order to make man made global climate change work.
May I suggest to you that you forget the politicians that are pushing global warming and look at the facts yourself? Read the reports and challenge them, sort of like your own peer review. Tell me how .05th of a degree spread out over 100 years is going to make a difference one way or the other. Learn the solar systems orbital mechanics and tell me how can one predict a weather system on a planet that takes 250 million years to complete one circle of the galaxy? Tell me how a science that is less than 40 years old is going to accurately predict the weather 100 years from now? they don’t even have 25 years of accurate data and they will freely admit that they can’t really predict the weather past four days with any certainty but you want to trust them to predict the weather conditions 100 years from now. I can do that! In the spring it will be warm, in the summer it will be hot, in the winter it will be cold and in the fall it will be cool.
While you are doing this peer review try this brain teaser.
The earth spins a little faster than a thousand miles an hour. Man uses a 24 hour clock. The extra minutes we discard each year adds up to about a day every four years. This means that every 100 years we add 25 days this will mean that our summers come late by 25 days could this be the reason why the summers are not as hot and the winters don’t get cold till almost spring?
And that's great. Tear the IPCC a new arsehole! I am confused that you keep bringing the IPCC into this, as I really couldn't care less about their reports.
This is the reason I keep bringing it up. All your scientists that claim that the emissions from man are such a hazard have at their root the IPCC report on global warming. Every link you have provided quotes or links to that report you don’t like as proof of their claim including Dr. Hansen. Yes, I went to his website and read his work. Most of it is his hatred of coal produced CO2, he makes a good argument but it is undercut by his reliance on the IPCC report that we all, including you, agree is worthless.
