Reblogged from Globalwarming.org, with PDF files converted for readability:
Yesterday, Rep. David McKinley (R-W.Va.) hosted a climate change conference in a technology park in Fairmont, W.Va.
A mixed panel of warmistas and skeptics featured Marc Marano of Climate Depot, Scott Denning of Colorado State University, Jim Hurrell of the National Center for Atmospheric Research, Joe Casola of the Center for Climate and Energy Solutions, Annie Petsonk of Environmental Defense Fund, Myron Ebell of the Competitive Enterprise Institute, Dennis Avery of the Hudson Institute, and John Christy of the University of Alabama in Huntsville, who participated by satellite link.
I emailed Dr. Christy and asked for permission to post his presentation on GlobalWarming.Org; he promptly sent me the files.
Dr. Christy’s Power Point presentation is available here. The accompanying text is available here. The main takeaway points:
- Popular scare stories that weather extremes – hurricanes, tornadoes, droughts, floods — are getting worse are not based on fact.
- In the U.S., high temperature records are not becoming more numerous.
- Climate models significantly overestimated warming during the past 15 years.
- Even if climate models were correct, a 50% reduction in U.S. CO2 emissions by 2050 would avert only 0.07°C of warming by 2100.
- If a policy is not economically sustainable, it’s not politically sustainable.
- The climate change impact of enhancing CO2 concentrations has so far been small compared to the public health and biospheric benefits provided by affordable, carbon-based energy.
30 May 2013 Written testimony of John Christy:
Congressman McKinley, panelists and guests, thank
you for allowing me to appear via the internet. Going
to the next slide.
The first point I want to make is that popular scare
stories of weather extremes getting worse are not
based on fact. In the upper left, tornadoes are not
increasing. In the lower left, hurricanes are not
increasing. In the upper right, snow cover is not
disappearing, in the lower right, droughts and floods
continue to happen as they always have.
Next. What about record high temperatures in the
U.S.? This chart shows that 2012 had quite a few, but
hardly the most. Indeed a careful look shows a
downward trend. High temperature records are not
becoming more numerous.
Next. What about climate model projections? The red
line shows the temperature response to greenhouse
gases that the very latest models indicate should be
clearly evident - the tropical atmosphere is supposed to
be rapidly warming. The green and blue lines show
what the real world has done. The models are
significantly wrong compared with the real world in
this signature quantity.
Next. Let’s suppose for a brief moment that the
models are correct. The red line here shows global
temperatures over the next 100 years. The harsh
policy that congress considered four years ago of
drastically reducing CO2 emissions would have the
effect seen in the green and blue lines – in other
words, no detectable impact. Energy costs would soar
without any benefit.
Next. As State Climatologist I work on many economic
development issues, including legislation to take
advantage of Alabama’s climate resources. One thing I
know about this area is that if an idea is not
economically sustainable, in the long run, it is not
sustainable no matter its other intentions.
Next – Finally. Affordable energy is the basis for our
standard of living today. Energy comes from the green box
here, mostly from carbon. The benefits of energy
are in the blue box, and who doesn’t want long life,
progress, plentiful food and so on.
The lower green box shows the physical consequences
of carbon-based energy production – invigorated
biosphere, increased food production and the debated
climate impact. The evidence I’ve presented shows
the climate impact of enhancing the concentration of
CO2 is not much.
However, I’m quite certain that making energy more
expensive will cause the results of energy in the blue
box to become more expensive and therefore more
scarce. I’ve lived in Africa and can assure you that
without energy, life is brutal and short. We are not
evil people for emitting CO2, we are good people
because we recognize the direct and powerful benefits
to human life that carbon-based energy supplies. With
that I’ll close, thank you.
