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
By addressing the magnitude of the climate threat with urgency, a powerful global climate change treaty would help establish a firm foundation for a sustainable economic future. This would set a more predictable framework for companies to plan and invest, provide a stimulus for renewed prosperity and a more secure climate system. Economic recovery and urgent action to tackle climate change are complementary – boosting the economy and jobs through investment in the new infrastructure needed to reduce emissions.READ MORE
This is absolutely wonderful news. There is no question that we don’t fully understand the complexities of our atmosphere. Our models which predict doom and gloom are woefully inadequate (which doesn’t make them incorrect – it just leaves room for extreme doubt).
Perhaps this study will solve one of my mysteries in the global warming discussion and that is that North America actually appears to sink CO2 rather than emit the gas. We know that carbon dioxide is increasing from man’s efforts due to the isotope nature of the CO2 in the air but we still struggle understanding how CO2 spreads through the atmosphere.READ MORE
When I first saw this article, I almost laughed. How could mushrooms be significant. But then I remembered that the northern forests are an extremely important part of the carbon cycle of the globe. I also remembered that the computer models need to accurately understand the roles of the northern forests in order to make predictions of doom due to global warming. Therefore, if mushrooms affect this contribution and if we don’t understand the mushrooms then we obviously have some issues with the models.
There is an old saying, “Garbage in = garbage out.” Whose turn is it to take out the garbage?
The fight against climate warming has an unexpected ally in mushrooms growing in dry spruce forests covering Alaska, Canada, Scandinavia and other northern regions

Carbon dioxide, the greenhouse gas linked to global warming, is accumulating in the Earth’s atmosphere at an increasing rate, according to a new study released by the US government’s National Oceanic and Atmospheric Administration. The research has renewed concern that the ability of the environment to absorb the gas may be waning. The NOAA study said the average atmospheric concentration of carbon dioxide in 2005 reached 381 parts per million, up from 2.6 ppm since 2004. The annual rate of increase, which has been recorded since the 1950s, now exceeds 2 ppm for three of the past four years. This is an unprecedented increase; 50 years ago, the annual increase was less than 1 ppm.READ MORE
Just a quick note to everyone to announce the 1 year birthday of this site. Last February 12, I kicked off this site with the following article:
I must say that I have enjoyed the last year and I continue to think that the discussion on this topic is still very relevant. I plan to continue this discussion and exploration for the foreseeable future.
I didn’t quite make my goal of averaging a new article every day. Instead, I have posted 351 times so I am 14 short. I am happy to report that almost 20,000 people have viewed this site in the last 12 months. I wish I could thank each of you personally but I am afraid that this public announcement must suffice.READ MORE
Gristmill – December 24, 2006
Gristmill has put a series of articles and for the most part they are excellent. I suggest you read all of them. This article is also very good although it does have a few items that, while not untrue, do not completely discuss the issue. I am sure that the author knows better but I wanted to point the incomplete statements.READ MORE
NOAA Magazine – March 21, 2007
This is fantastic. NOAA has released a new diagnostic tool that will monitor the changes in atmospheric carbon dioxide and other atmospheric gases by region and by source. This will allow users to understand the pollution that is being put into the environment.
In the above image “negative fluxes (blue regions) indicate places where uptake of CO2 occurs. Positive fluxes (red colors) indicate places where emissions of CO2 occurs. The figures include biological and fire fluxes, no fossil fuels.”
The online data framework distinguishes between changes in the natural carbon cycle and those occurring in human-produced fossil fuel emissions. It also provides verification for scientists using computer models to project future climate change.
I often refer to the Carbon Cycle but it occurs to me that many of my readers may not know what that is. Here is an easy pictorial overview of the cycle.

Science Daily – October 20, 1998
I have been hesitant to talk about this study that is nearly 10 years old now but I have searched high and low and I cannot find a single reference that refutes the study. In this study that occured from 1988-1992, it was found that the CO2 levels in the air decreased as the natural westerly flow moved air from the Pacific Ocean to the Atlantic Ocean. The theory is that the CO2 concentration on the West coast would be X, the generated CO2 production by US citizens would be Y, and the CO2 concentration on the East coast would be some level above X but probably below X+Y since some sinking of carbon would occur.READ MORE
