Less feedback forcing than previously guessed at

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.

Time for a Climate Change Plan B

Nigel Lawson has done a remarkable job of explaining the basic problem with limiting the use of carbon based fuels in our world today. His argument doesn’t really take a side on the merits of the science but rather on the realities of economics. His opinion recently showed up in the Wall Street Journal and I have taken the liberty to include selected parts here.  I suggest that you click through to read the entire article.

Lord Lawson was U.K. chancellor of the exchequer in the Thatcher government from 1983 to 1989. He is the author of “An Appeal to Reason: A Cool Look at Global Warming” (Overlook Duckworth, paperback 2009), and is chairman of the recently formed Global Warming Policy Foundation (www.thegwpf.org).

Scientists and Engineers are upset

If you read this site often, you will know that I am an engineer by training (even though I don’t currently practice). I tend to respect this profession a great deal as being fairly straight-forward and hard working. As a group, they also tend to be a pretty smart bunch.

One of the major trade rags in engineering is C&EN (Chemical and Engineering News). It is edited by Mr. Rudy Baum. If you aren’t in that trade, you would probably never pick up an issue so you may not be familiar with it. I haven’t read the publication in a long time but was recently made aware of a bit of controversy by Climate Depot. While the readers of C&EN are likely not climatologists, the science of CO2 and its affect on the atmosphere is very steeped in chemistry which their target market knows a bit about.

The Climate Change Climate Change

Funny title.  You may have to read it a couple times to get it.  I didn’t create it – I am not that creative.

Kim Strassel has an opinion in the Wall Street Journal where she does a fair amount of reporting on the difficulties that politicians are having in dealing with the coming global warming catastrophe. It seems that politicians are a lot like many of my readers, when scientists can’t agree on what is happening (and not just little disagreements but violently opposed to each other) one should probably wait to spend trillions of dollars on which side is correct.

Here are some highlights from Ms. Strassel’s article:

Ethanol’s Grocery Bill

Very good article in today’s Wall Street Journal regarding the use of ethanol and how it costs a great deal to add it to our liquid fuel supply.  The article points out that depending on the technique used to create ethanol, it adds 5%-34% more greenhouse gas to the environment than pure petroleum.

There is also a case to be made that there is pressure put on food prices due to ethanol production as well.

I am not totally against using ethanol as an additive. I think there is some advantage to keeping the market alive and viable to spur development of new techniques of creating the liquid and new crop energy sources other than corn.
