Good Essay On Climate Change
University of Michigan professor Andrew J. Hoffman has a very interesting analysis on "Climate Science as Culture War."[Read Full Blog Post]

Thanks, Bryce. I will read the article. But to clarify, isn't water vapor the chief greenhouse gas?

An excellent article and I hope that anyone making comments here about read its entirety!

Thank-you Bryce for providing access to an interesting and insightful article. Please continue the discussion on climate change in future posts. The issue is too important to be ignored.

Good article, indeed. Reading this article makes me glad that, by being someone in the atmospheric sciences, I can make my own opinion on climate change. Not that it changes Professor Hoffman's argument at all, but according the National Climate Data Center, water vapor is the largest (I assume that is what Hoffman meant by greenhouse gas. However, the UN site mentions that CO2 has the largest GHG emissions by volume, which could be what Hoffman was thinking.

Bill, you probably have the right interpretation on Prof. Hoffman's discussion--that carbon dioxide has the largest greenhouse gas emission by volume. Your response edited for readability as it was displaying some garbled characters in the type.

Bryce, I have been following the weather, markets, news here for a while and the climate change discussion has been most interesting. Observations if I may. "Consensus" seems to be used by only one side in this ongoing debate. The word is used as meaning without decent, unanimous. Hmmm. Where? In what community? We, in the West, are seeing the effects of burning of high carbon fuels. Forest fires have made it impossibleto see over a mile some days and the fires are over 110 miles from my location and some have been over 500 miles away. Smog would not come close to what we have seen for over 2 months. Where is the concern? Where is the calculations of the carbon footprint? Only man burning of fuels is causing climate change? One other note, how can we as Americans believe everything that "science" puts out in the media when so many studies contradict each other. Yes, even from the peer reviewed publications. Peer review has in my calculations become suspect and that's a shame. Science is the loser when reviews become based on biases. Respectfully.

It's a good thing that God gave us brains to overcome the messes we create. Leaving everything "up to God" sounds like denial to me. How can we think there's no effect on God's planet when you consider the millions of human created cars on the road and human created furnaces running and human created industrial plants producing goods for consumers, that all these individual "bonfires" don't create heat and carbon of Biblical proportions? Maybe we shouldn't call it "climate change." Maybe we should use another term like "heating and carbon caused by millions of civilized individuals who like to have conveniences and live in an economy that demands lots of activity and power to produce for survival of billions more humans than the planet has ever seen." It's hard to get a brain around this one isn't it?

One quick comment about the CO2 in the atmosphere. I read an article some time ago regarding a test that was performed in a science class where CO2 was concentrated in the air space above some plants while standard arie and then higher than normal O2 levels in a third test. The results were that the High O2 yeilds were low, standard were as expected and the High CO2 greatly increased the yield. The question that was raised by this experiment is whether or not the higher CO2 levels in our atmosphere, albeit slightly higher at or just above sea level, could be a contributing factor to the increase in yields in our farms and increase in growth rates of trees.
