Temperatures in Nevada rise as temperatures in Nevada fall

I know, you have a big question mark above your head, but no, the headline is not a type-o. This is just an example of how news is reported, and anything can be slanted to look the way you want it.

First, from the AP on July 25th, Study: Nevada has big temperature gains.

This goes on to show how NV has been most affected by global warming. One of my favorite quotes from the story:

“The scientific evidence of global warming is incontrovertible, and Nevada is feeling the heat more intensely than most of the rest of the U.S,” said Stephen M. Rowland, Professor of Geology at University of Nevada, Las Vegas.

“Only a tiny bit of this increase in temperature can be attributed to increased urbanization the so-called urban heat-island effect,” Rowland continued. “Global warming is here, and we better get serious about confronting it.”

First of all, RUN, don’t walk, from any scientist who says its incontrovertible. That goes against all science, since science is always supposed to be questioning in order to find the truth.

2nd, from the National Weather Service

I guess good ol’ Steve didn’t bother to check with the National Weather Service. According the NOAA, the average maximum Las Vegas temp is almost a full 1.5 degrees lower than it was in the 1940s. See, if you limit your study to pick out the time-frame that works to support my argument, then your theories work. Sorry Stephen, that’s not science, that’s agenda. Since the 1970s the average maximum temperature is up .2 degrees, but since the 40s it’s DOWN 1.5 degrees.

Next time Steve, pick the 60s where you could have picked up an extra 1/2 of degree.

  1. 1st: Dr. Rowland is talking about Nevada. The graph you refer to is for Las Vegas only.

    2nd: Dr. Rowland is talking about the daily mean temperature. The graph you refer to is for the daily high temperature only. Even restricting to Las Vegas only, the daily mean temperature in the 90s is higher than that in the 40s by 0.4 deg.C (0.7 deg.F).

    3rd: The graph you refer to only goes to the 90s. The daily mean temperature in Las Vegas only, averaged over the (incomplete) decade of the 2000s, is 1.35 deg.C (2.4 deg.F) higher than that in the 1940s.

  2. I’m sorry, I didn’t realize that global warming didn’t like to gamble, and avoided vegas. How can it be incontrovertible if it’s not even occurring in all areas of the state?

    I was talking about the title of the AP Article- big temperature gains. But yet, in places, the average max temp hasn’t risen, it’s dropped. We could take last yr to this yr, and prove global cooling in the Northeast. My point is, it’s all about the selective sample. Even from the 40s, 50-60 years is a blip on the global patterns of a planet that is billions of years old.
