Global warming may reduce hurricanes hitting U.S.

Reuters – January 23. 2008

What in the world is going on here?!?!?! Do we understand so little about our climate and environment that we can’t even figure out for sure if hurricanes are going to be less frequent or more frequent with global warming? I repeat my call for more effort to truly understand our climate before we spend trillions of dollars to try and change the environment – a sum that will likely cause the death of thousands of people.

This also flies directly into the face of former Vice President Al Gore and his film “An Inconvenient Truth” perhaps Mr. Gore should consider giving back his Nobel since one of his strongest statements and most concerning images in the movie was the certainty that hurricanes would increase and cause more catastrophes such as New Orleans.

New Study Increases Concerns About Climate Model Reliability

ScienceDaily – December 12, 2007

If you read this site on a regular basis, this will be no surprise to you. A couple fairly prominent and outspoken scientists are trying to explain that the computer models that are used for predicting the massive problems of the future are not quite as accurate and foretelling as some will have you believe.

Many people will say that the climate projections are good enough and we should go into massive retooling of the worlds economy based on this small amount of information. This is the common theme over at RealClimate. While the jury is still out, in my opinion, as to what the future holds for us, there is no question that we do not have very good evidence on either side of the issue. The current models make numerous assumptions and any errors in the logic will tend to exaggerate over time.

Follow-up: NASA Sees Arctic Ocean Circulation Do an About-Face

A few days ago, I wrote about a new NASA study that suggests that the Arctic Ocean is reversing the circulation direction. The study theorized that the circulation direction was a major contributor of the melting of Arctic ice.

At the time that I wrote the article, there was very little analysis by other scientists on the study (still isn’t). So I reached out to several of the contributors at RealClimate and asked them what they thought.  Dr. Benestad replied to me and he has agreed to let me reproduce his comments here for all to learn from. I would like to publicly thank him for his willingness to help us understand this.

Climate skepticism: The top 10

BBC News – November 12, 2007

If you are a global warming skeptic (or if you deal with one regularly), you need to read this article on BBC. It covers a claimed top ten reasons that skeptics likely cite regarding global warming and then gives a short reason why the excuse is not valid.

35 Inconvenient Truths: The errors in Al Gore’s movie – Part 1 of 5

Several days ago, I posted about RealClimate.org’s defense of the 9 ‘mistakes’ that a British court found in “An Inconvenient Truth” (AIT). My review was not well regarded by many at RealClimate as they defended their defense. My point at the time was that extremism is bad in all ways. Even if you think that the world is going to end due to human induced global warming, you must be able to see spin for what it is and confront it.

Conversely, if you think that all this global warming conversation is hooey, you still should not say that everything out of Mr. Gore’s mouth is biased and wrong. We need to evaluate each claim on its own and seriously discuss the viable issues.

Convenient Untruths

RealClimate – October 15, 2007

I have suggested that my readers visit RealClimate before as I consider it a fairly well written site. The site has contributions from many people that study the weather for a living (as authors and as commenters) and so they tend to really dig into the scientific details. You can learn a lot from reading the site and the comments are typically quite insightful. They have a direct link to IPCC so they are fairly staunch defenders of that organization and so sometimes they are not quite fair and balanced. They also tend to love their computer models, a devotion that I don’t share.

Does the Earth Have a Temperature Regulator?

24 Hour News & Blogs – September 9, 2007

This is a very interesting post on this news site that compiles and discusses the observed phenomenon that historically CO2 rises after temperature rises. Real Climate goes on to describe that this rise in temperature is aggravated by the warmth absorbing properties of the increase carbon dioxide.

One would assume that this is a runaway train. Temperature rises then CO2 increases causing more temperature increase which should cause more CO2 to enter the atmosphere. But something has happened in history that we don’t seem to understand – eventually, the temperature drops and so does the CO2.

Why global climate models do not give a realistic description of the local climate

RealClimate – May 27, 2007

I have written about this excellent site often (here and here and here and here and here) but I really must encourage all of my regular readers to read this article on climate models.  As you know, I regularly have called for more effort to be done in this area of computer technology as I honestly believe that the climate scientists need a concerted effort for a rapid increase in capability in handling massive amounts of numbers and equations in parallel.

Thinking Blogger Award

This is a different type of post.  I will still do my regular global warming posts today but I need to take care of a little business.  Please do me the honor of reading this posting with as much attentiveness as my traditional posts.

I have been nominated for a blogging award, the “thinking blogger” award.  I am extremely honored by this award that someone out there actually feels that I make them THINK.  I am not sure that it is possible to give someone a better compliment (I take that back – Donald Trump, I will accept a million dollars if you are feeling generous).

Hansens 1988 projections

RealClimate – May 15, 2007

RealClimate is a great site.  If you are not reading this site regularly, you should.  Their articles tend to be much more technical than what I put here on a daily basis and the frequent commentators in the comments tend to really know the science and chemistry behind the weather.  I know that a lot of professionals consider RealClimate to be part of their weekly reading regiment. That being said, I don’t always agree with everything that the editors post (what would be the fun in that).  They certainly have a theme and a message for their site and one should take that into perspective but since I encourage everyone to have an open mind on these very technical and critical matters, reading a well-written site like RealClimate is part of the process.
