Not All Scientists Believe Global Warming is Man-Made
Recently, Nicola Scafetta of Duke University and Bruce West of the Army Research Office published an article in Physics Today that suggests variable solar intensity is more strongly coupled to global warming than previously believed. The article, entitled, “Is climate sensitive to solar variability?” is a convincing and well-written piece arguing that if the sun and Earth are modeled as two complex networks exchanging information, temperature changes on Earth can be correctly determined from time variations in solar intensity. The Scafetta and West model even predicts a drop in global temperature in 2002, which was in fact observed. Additionally, it explains the statistical variability in Earth’s temperature, which had previously been interpreted as background noise in global climate change models.
Interestingly, this article is relegated to the Opinion section of the magazine. It does not appear the Feature section with all of the other technical articles. It seems the editors of Physics Today believe that an article presenting evidence against anthropogenic (man made) global climate change does not warrant publication with “factual” scientific articles.
The popular media has declared that scientists agree global warming is probably anthropogenic. For example, CNN.com posted an article entitled “Scientists: Humans ‘very likely’ cause global warming” in which the plural “scientists” seems to refer to the entire scientific community, and “very likely” is certainty to better than 90 percent. Deep within the article is subtly stated that the “scientists” in questions are not all scientists but merely a small panel. However, the damage is already done by the title alone.
While I have tried to avoid taking sides in the global warming debate, I have emphasized several times in this blog that scientists by definition do not know anything with absolute certainly; particularly whether global climate change is real and if so what is causing it. For more details on this argument, check out my post “Global Warming is Too Hot to Handle”. Moreover, the scientific community is not nearly as unified in agreement about the causes of global warming as the popular media suggests.
Nonetheless, it is very difficult for any respectable scientist these days to suggest global warming is anything but anthropogenic. Like Galileo standing against the church, modern scientists proposing explanations for global warming other than man-made greenhouse gasses doom themselves both in the public eye and the scientific community. The anthropogenic global warming theory has become so popularized that peer pressure coerces scientists to look the other way while the underlying cannons of the profession are compromised.
It takes brave scientists to swim against this modern inquisition, and Nicola Scafetta and Bruce West have been unduly disenfranchised by having their technical article published in the Opinion section of Physics Today.

i believe in global warming but man has little if any to do with it, in the tenth century the vikings were farming in greenland and people were cultivating grapes in England the world will always heat and cool just like an oven this so called global warming is another excuse by governments to tax the people the sun is the main factor in global warming

I have a theory about CNN\’s and other media\’s open support of the AGW-based message of global warming. While it is possible that the world population has had little effect on our climate, telling people that they DO have an effect, will help improve our approach and use of resources that cause pollution, or are limited and need conservation (e.g., water, oil).
As in all things, the way concepts are marketed defines them, for good or bad. And if humans can change their attitudes which will ultimately improve the planet, I am all for it.

I think that cbrtxus misrepresented CNN. They may have a political axe to grind but what's more important is just making headlines that get peoples attention. They couldn't care less about truth and reality. The objective is to sell advertising and get more revenue. Accuracy and objective reporting are too much trouble and can never fit into the 15 second window they have between commercials.

i don't believe in global; warming its a bunch a bullllll
dmfadrilan commented:
If global warming is anthropogenic, therefore, human can unmake global warming. If that''s the case, human can control the sun''s heat energy emission. What make human so powerful, when he is a tiny being in the universe?
Dr Burns commented:
The alarmist view is based on politics, not science. Magazines and journals need to be political to maintain readership.
cbrtxus commented:
You mentioned the CNN report (“Scientists: Humans ‘very likely’ cause global warming”). Apparently CNN believes that to be proper journalism. Perhaps they can do a follow-up piece by interviewing Kindergarten kids to show that most people believe in Santa Claus. How can these people not know that they are perpetrating a fraud? The fraud has nothing to do with whether there is significant anthropogenic global warming (AGW) or not. The fraud is engaging in such misrepresentation in an attempt to bolster the case for AGW. Give us the objective “facts” Mr. and Ms. Journalist. Presenting the opinion of a small group of scientists is fine, but don’t imply otherwise in the title. That isn’t what a professional journalist should do. That is the sort of thing that a propagandist does. You are bringing discredit on what should be a noble profession. We shouldn’t have to watch network news or read a news story and then wonder what “really” happened.

As someone who has not delved deeply into this debate and the underlying science, it is very difficult to effectively weigh the evidences both for and against global warming. This is primarily because the popular media has started this "inquisition" of sorts to "raise awareness". Another interesting comment I heard on talk radio was that the goal of this research was "the reallocation of wealth and resources," which conservative talk radio believed to be an attempt to control the world''s resources (socialism/communism). Certainly the allegations against Al Gore by the former owner of The Weather Channel over carbon credits help to stimulate this train of thought. It would appear that there is enough political power and money on both sides of the global warming debate that real scientific research into this matter will be at best difficult to perform, and at worst, impossible. And as for the average person who doesn''t delve deeply into this matter, they will be at the mercy of the victor in this debate.

First, let's define "no-compromise." In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
