Man-made global warming

What if proponents of man-made global warming (MMGW) as “settled science” are wrong? In 1970, we knew that stress caused stomach ulcers. The real cause: A bacterium, H. pylori!

In 1995, Michael Mann proposed the hypothesis that CO2 was responsible for MMGW in the years 1970-1995. According to Mann, the graph showing the gradual rise of temperature moved from the lower left to the upper right. This line looked like a hockey stick, because it was said to show a rise in temperature at the right end -- like the blade of a hockey stick. As the upward blade correlated with the rise of CO2, Mann argued that CO2 caused warming.

However, McIntire, using more appropriate statistical methods, showed the Mann temperature graph with blade pointed up, was statistically incorrect and there should be no additional warming.  Now there is much skepticism.  

In addition, since the artificially high temperatures of 1998 (an el Nino year), we have had 16 years of flat or lower temperatures.  2013 was 2 degrees colder than 2012.

Historically we see the temperature variation of the “medieval warming period” (1000-1250), followed by the ”little Ice Age” (1650-1850), then warming to 1998. We may now be simply reverting to the mean.

Patrick Moore, Ph. D in ecology, co-founder of Greenpeace, in testifying before the Senate recently, has broken completely with the MMGW interests. He states that the MMGW movement has been taken over by the left, certain political ideologues and academics after grant money.

Who lacks class?

In reference to Al Slaughter's comments about Duke class (Letters, March 19), I would think he must be a good lip-reader to see all the words used in the game, and think he should tutor the players at UNC on use of that skill since it seems they can't read anything else.

As for his opinion on our class, at least we go to class and have real honest-to-goodness professors who are also there. Help me if I'm wrong, but I don't recall any of our players being arrested for carrying drugs or in possession of guns that just happen to fall out of a car.

Keep heat on DENR

Thanks for Sunday's editorial on the state Department of Environment and Natural Resources.

Of course, the headline should have been "keep the heat under DENR's feet" since all the shenanigans being revealed show that hoping DENR acts to protect our air and water isn't enough; they need public scrutiny and pressure to keep them from thinking "customer service" to polluters is their only job.
