Dedicated to the balanced discussion of global warming
Most of the long-term climate models show feedback from an increase of carbon dioxide that ultimately creates more carbon dioxide. The theory is that as CO2 increases, the temperature increases. As the temperature increases, it forces more CO2 to be released from CO2 sinks or it causes less CO2 to be absorbed. This extra CO2 causes a dramatic increase in temperature – which releases more CO2. Many of the models that predicted the end of world had this increase in CO2 and temperature. It really wasn’t the CO2 from man that was the problem, it was the tipping point that was reached by man’s CO2.READ MORE
I first saw this on Net-Cool which is a great site to subscribe to for finding really interesting things on the web.
This movie explains some of the reasons of concern for monitoring the increase in temperatures that we have felt since the 1960s. It is very well done and enjoyable to watch. Unlike An Inconvenient Truth, it admits that this is not pure imagery but some CGI has been done.
If you can handle the bandwidth, you will see better graphics here rather than watching the embedded YouTube video below.
AccuWeather.com has an excellent update on the status of the Arctic ice last month – July 2009. Looks like the melting was pretty bad.
And here is an image from NSIDC (National Science and Ice Data Center) showing the current ice coverage and the median.
I have talked about RealClimate.org many times in the past. In general, the gentlemen over there are pretty smart but they do tend to be one-sided in their analysis. They consistently take the side of “global warming is caused by humans” and they don’t treat others with much respect.
I started questioning their partisanship when they lashed out at the UK judge that said that “An Inconvenient Truth” was not 100% factual. They didn’t like me calling them out on that. They then spiked some of my comments on their site when degraded scientific discussion to a challenge of who has a bigger wallet.READ MORE
Great post on Watts Up With That regarding the supposed warming in the Arctic. It appears, like we have seen so often, the warming that has occurred is only dependent on when you start from. If you look at the last couple of decades, you may see warming but if you go back and look at the full expanse of the temperature data that we can gather, since 1958, the warming claim becomes much more tenuous.
Jump over to read WUWT if you like as the description is far clearer than what I will reproduce here.

This article misses out by not making a big enough distinction that weather is not climate and climate is not weather. The amount of ice in any given 2 or 3 year stretch has as much to do regarding global warming as the occassional all time high or low that is hit in Peoria, IL. I have talked about weather v. climate before but we always seem to go around to the same things.
Last year, there was a great deal of talk about Arctic Sea ice and the fact that it was vanishing. Very little talk at the time had to do with the currents under the ice (except for here). The end of the world was at hand though if you read some blogs!READ MORE
There is no question that our climate has changed slightly compared to 20 years ago. Most of the data points to increases of temperature and the most significant (and obvious if you are in the Arctic) is the diminished amount of ice in the Arctic Ocean. While there is some question as to the cause of this melting (see my ocean currents article), there is little question that it is occurring.
This article discusses some of the observations that scientists have seen regarding the ice melt and some possible repercussions. The article is somewhat refreshing though in that it focuses on what can be observed rather than focusing on what might be causing the warming. Since it was so evenly reported, I felt it was of significant interest to my readers.READ MORE
It looks like we are going to have to wait for awhile now for better data on what is really going on with our atmosphere and climate. The satellite that NASA sent up to study the flow of carbon dioxide developed technical difficulties and crashed.
Once again, we see that our ability to travel outside of our world is still quite experimental and we struggle to do it with the repeatability of plane flights. If I was a conspiracy fearing individual (which I am not) I would question if scientists deliberately sabotaged the flight so that real data that could prove or disprove climate models could not be gathered. Such speculation is obviously foolish though.READ MORE
These statements are part of the public record so I am comfortable that I do not harm any copyrights by reproducing them in entirety here. Please note that these are the prepared statements of former Vice President Al Gore.
If you don’t want to read such serious stuff, I suggest you read “Canceled Due to Global Warming” and have a good chuckle.
Statement to the Senate Foreign Relations Committee As Prepared Hon. Al Gore Wednesday, January 28, 2009
We are here today to talk about how we as Americans and how the
United States of America as part of the global community should address
the dangerous and growing threat of the climate crisis.
I originally found this opinion in “The Detroit News” and so you can click through and read the entire article. I really cannot explain this topic better than Mr. Taylor and I suggest that you read my highlights here and then read the full article if it is interesting to you.
Understand that Mr. Taylor works for the Heartland Institute which is known as being pretty close to the edge when it comes to rational discussion on this issue. However, even people with extremely strong feelings on an issue are not totally wrong and need to be listened to.READ MORE
