Dedicated to the balanced discussion of global warming
I found this study by reading the blog at AccuWeather.com. If you are interested in climate, then you should spend time reading what the meteorologists over there have to say.
A study by 3 researchers and published in the Journal of Geophysical Research has concluded that the weather variations (both increases and decreases) are the result of natural climate processes. They find that the Southern Oscillation is a key indicator of changing global atmospheric temperatures seven months later.
The paper is titled “Influence of the Southern Oscillation on tropospheric temperature” and following is the abstract:READ MORE

A team of University of Washington scientists has been studying the insect population of the tropics and concluded that an increase in temperature could many species at risk of extinction. I give more credence to these types of studies to articles on climate models since, in this case, it is possible to do some true cause and effect analysis as well as maintain a control group. The problem with climate models is that they are simply mathematical equations that are developed by mathematicians and then run on moderately powerful computers.
I wrote about Brazilian ants several months ago. This new study seems to be in contrast to the conclusions of that article. This is not unusual in science that different studies with different techniques results in different conclusions.READ MORE

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.READ MORE
I have no idea if this is good news or bad. I only find it interesting that life continues to evolve even as the world changes. If you are an optimist you will say that this means that the dire predictions by many are false. If you are a negativist you will point out that this is terrible that potentially man is causing an unnatural evolution.
I tend to be a centrist and try to find the middle for all things. So in this case, I think it is wonderful that the animal and plant kingdoms will find a way to thrive even if man is potentially killing other types of life off. According to the theory of evolution, life has always been evolving to accentuate the ability to survive – this is simply one more point on the curve. I also find it sad that some species will cease to exist due to this change but acknowledge that extinction is part of the cycle of evolution.READ MORE

This is a very good overview of a scientific paper that details how a historic global warming event dramatically changed the Earth’s ocean currents. The article does not lay significant claim as to what caused the warming, only its dramatic effects. The article does compare today’s level of carbon dioxide and theorizes a similar catastrophe.
The big event, the Palaeocene/Eocene Thermal Maximum (PETM), saw the planet’s surface temperature rise by between five and eight degrees C (nine and 16.2 F) in a very short time, unleashing climate shifts that endured tens of thousands of years.
With a painstaking reconstruction, Nunes and Norris found that the world’s ocean current system did a U-turn during the PETM — and then, ultimately, reversed itself.

This is good but sad news. I am extremely happy that we are continuing to invest scientific effort and money in the gathering of data and the understanding of our climate. That is the good news. The sad news is that there are some in this world that believe that we don’t need to do this scientific process because they already know the answers: the world is going to end due to human fault and we need to spend billions (trillions?) reversing the process.READ MORE

This article details a study regarding global warming that occurred 55 million years ago and the very dramatic and long-term changes that appeared to be caused. It is a very interesting study that should be understood to be “theory” and not fact. It is great reading if you want to understand what could occur if the earth’s temperature increased dramatically.
An extraordinary burst of global warming that occurred around 55 million years ago dramatically reversed Earth’s pattern of ocean currents, a finding that strengthens modern-day concern about climate change, a study says. The big event, the Palaeocene/Eocene Thermal Maximum (PETM), saw the planet’s surface temperature rise by between five and eight degrees C (nine and 16.2 F) in a very short time, unleashing climate shifts that endured tens of thousands of years.
Letter to Physics Today – March 2007
This is a must read letter to the editor. It really calls into question one of the major beliefs of those who state that global warming will cause cataclysmic damage to our way of life. Basically, many people believe that if the major ocean currents change dramatically, that we will have major changes to our local weather in parts of the world. While this belief has some legitimacy, there does not seem to be a preponderance of evidence that such a change is imminent.READ MORE
