The US congress sub-committee on Energy and Commerce Committee held hearings on whether to restrict in some way the EPA’s regulatory authority relative to greenhouse gas emissions.
There were 7 scientists invited to testify. Three of the four who argued not to restrict the EPA played a key role in the last IPCC report (and will also in the next one) and generally started with the position that IPCC science was sound and there was a consensus of all real scientists.
In the attached analysis we take a look at the IPCC based science. We are going to ignore all the many ‘gates’ that were uncovered like the Himalayan glaciers, Amazon rain forests, how many real scientists there were who authored the key summaries and all the issues as to whether the summaries truly reflected the scientific information in the chapters and despite claims to the contrary, how a significant percentage of citations were not peer reviewed.
We will not attempt to address the issues of sensitivity for CO2 or solar and cloud and water vapor feedbacks relative to the models. We will also ignore the many model shortcomings – like inability to forecast regional patterns, ocean oscillations, etc. Each of these alone discredit the consensus ‘settled science claim.
We will focus on how actual data compares to the consensus science, model based virtual world view of climate.
We will look at some of the major findings, assessments or model predictions from the IPCC and other national climate centers and NGOs, that we believe have failed and let you decide then whether or not the their science and model projections should be the bedrock onto which we build public policy.
The ten issues:
1. Warming is said to be unprecedented and accelerating. It is neither.
2. Global warming is not GLOBAL
3. Winters would grow increasingly warm
4. The entire Northern Hemisphere would experience less snow and snowcover
5. The arctic oscillation (AO) would become increasingly positive, aiding in the warming
6. Global warming would lead to a permanent or semi-permanent El Nino
7. Atmosphere will warm faster than surface (because that is where the heat trapping gases are).
Enlarged. Balloon data for actual 100-300 mb from 20S-20N from NOAA ARL Angell (anomalies relative to base period 1968-1977) compared to models forecasts of warming 20S-20N 100-300mb. Note the cooling observed where models suggest most GHG warming. This is similar to depictions from Singer etal NIPCC 2007 and others.
8. Record highs and heat waves are increasing
9. Sea levels are rising at an increasing, alarming rate
10. Droughts and floods will worsen
We have actually made a list of 30 such ‘failures’ or ‘shortcomings’, but decided to focus on the first ten.
