Global Warming on a Cooling Earth?
by Bob Webster
The true "deniers" are people like Peter and Andrea. They deny reality. Here are some facts: 1. Sea surface temperatures have cooled as Earth's "global average" temperature has cooled which has caused a DROP in sea level over the past few years (as water cools, it contracts). See http://icecap.us/images/uploads/SeaLevel_TOPEX.jpg and http://icecap.us/images/uploads/Sealevelsince2002.JPG to view dramatic trend reverse in recent years. 2. IPCC AGW predictions rely on an assumed 3-to-1 positive feedback from water vapor warming as a consequence of CO2 warming. A recent analysis that stands unrefuted clearly demonstrates the IPCC vastly overstates the feedback (which could be negative). See http://www.webcommentary.com/monckton.htm 3. In no period in Earth's climate history (going back at least 500 million years) has the greenhouse effect played any significant role in climate change. During some of the coldest Ice Eras (which last 40 to 60 million years), Earth's atmospheric CO2 was at levels 15 times what they are today (http://www.tcsdaily.com/article.aspx?id=010405M). See also http://icecap.us/images/uploads/MSUCRUCO2.jpg for an illustration contrary to the IPCC AGW claim that as CO2 increases, so will global temperatures. 4. Recent summer Arctic Sea ice melt peaked in 2007. AGW theorists predicted an ice free Arctic, or at best, an record ice melt in summer 2008. There was 9% more ice during the minimum ice coverage of summer 2008 than in 2007. Studies now reveal that Arctic ice retreat was not due to warmer temperatures, but rather a change in ocean and atmospheric long-term patterns (PDO, AO, AMDO, NAO, ENSO, etc.). This fall's Arctic Sea ice increase is the most rapid of recent records. See http://icecap.us/index.php/go/joes-blog/arctic_ice_increasing_rapidly/ 5. The IPCC AGW theory requires the existence of a tropical mid-troposphere signature. No such signature is observed (http://www.webcommentary.com/missing-gh-sig.htm). 6. The IPCC AGW theory requires polar surface temperatures to rise prior to surface temperatures increasing in lower latitudes. The Antarctic is on a six-decade cooling binge that saw the largest extent of Antarctic Ice ever observed during the southern winter of 2007 (similar to record growth of Arctic Ice in the northern winter of 2007-2008). See http://atoc.colorado.edu/wxlab/atoc1050/1050%20ppt/Global%20warming%20quiz.ppt a powerpoint presentation by Dr. Richard Keen (Global Warming Quiz). 7. The IPPC AGW theory is based on the notion that increased atmospheric CO2 will trigger "catastrophic" warming. There is no evidence to support that theory. Pillars of the theory (tropical mid-troposphere "signature" and rising polar surface temperatures) have not been observed while atmospheric CO2 continues a fairly steady linear trend upward that began 300 or so years ago (about 1 degree C per century), well before the Industrial Age began. Actual variations in temperature over several decades are normal climate variations and nothing in the last two decades of the 20th Century is unusual. The IPCC has not studied either the causes of natural climate variability or the nature of natural variability that would allow it to put into perspective any perceived human component to climate change. See http://icecap.us/index.php/go/joes-blog/new_detailed_analysis_of_global_temperature_data_does_not_support_significa/ and note the chart that clearly shows the dominant effect of natural forces of climate variability other than CO2. In short, the AGW theory is completely and utterly invalid. Those who continue to try to perpetuate it are either ignorant or dishonest.
