Well the long awaited report, actually not long enough, was released on Tuesday June 16. The Climate Change Impacts in the United States report (download here
) Executive Summary began rather predictably with, " Observations show that warming of the climate is unequivocal. The global warming observed over the past 50 years is due primarily to human-induced emissions of heat-trapping gases." You can't get any more predictable than that. I could go on but rather than pick on all the gaffs in this report, I will select a couple of the more insidious assertions.
Ocean Acidification is the fall back position for the global warming activists. The report makes the claim that it will harm shelly creatures in the world's oceans. This is pure fantasy. This interesting demonstration
illustrates how fast the CO2 dissolves in water as carbonic acid and converts to calcium carbonate. The calcium carbonate falls to the bottom of the ocean where it is used by creatures to make their shells. It happens quickly as you can see. There is enough Calcium in the oceans to combine with all the coal and oil produced CO2 currently in the Earth 100 times over. The ocean will not become acidic. The thought is that if the oceans become more acidic, the calcium carbonate will dissolve leaving nothing for the shelly creatures. This can't happen. For a more detailed explanation go here
Interestingly, the report says that precipitation changes are occurring around the world. They cite Africa. They should not have done that. Will Alexander has been showing how the Sun is changing precipitation patterns over the last several decades. He also is predicting, not projecting, a severe drought based on solar activity. For those not familiar with the difference between predicting and projecting, projecting is a weasel word indicating that the outcome is based on certain assumptions which may or may not be valid. I include some of Will's articles here
Interestingly, the report shows a graph of the decline of glacial ice. As I discussed here
, global ice is about on the average for the 1979-2002 average. So where is the decline. There was an interesting presentation
(Dr. Syun Akasofu Session 1 Track 1) at the 2009 International Climate Change Conference held in NYC in March. It showed slides of glaciers in the mid 20th century and today. There was a significant receding. Then they showed photos of the extent of these glaciers as early as the 1600's, and the glacier was very much bigger than the 1950's photo. There were several instances of this around the world . The point is, glaciers are melting. Duh! And they have been throughout our current interglacial period, the Holocene. But overall, Ice Mass is about on average.
Then they talk about fingerprints in the climate puzzle. They discuss the temperature of the troposphere and stratosphere. Green house gas warming would result in a significant rate of warming in the troposphere but radiosondes (balloons) direct temperature readings had not shown that. Warmers cried foul and claimed that the signature effect
(figure 6 is the actual temperature profile) wasn't necessary to show GHG warming. So what did they do? They used a model and wind shear measurements to fabricate a temperature profile using the wind shear as a proxy ( usually substituting something you can measure for something you can't ) for direct temperature readings. Proxies don't give results as accurate as the real thing and when you model the effect, it is a crap shoot. Needless to say the confidence in these temperature readings are low. The pictures illustrating these results are on page 21 and are exactly like the theoretical plates that were in the AR4. But now they are completely legit. Phooey!
And of course they discount the effect of the Sun discussed here.
I am going to leave this here and pick it up in Part 2. Feel free to read ahead in the report and see if you can find more problems. And don't miss the discussion
