A Climate Essay from Dr. Bill Gray

Essay by Dr. William Gray, climate scientist at Colorado State University. He writes, "there is considerable evidence that the global warming we have experienced over the last 30 years and over the last 100 years is largely natural." He says that many thousands of scientists do not accept the human-induced global warming hypothesis as presented by the IPCC reports. Climate models "have basic flaws". It is very difficult to obtain government grants to study natural climate change. "The normal scientific process of objectively studying both sides of a question has not yet occurred.".



Corbella: Pause in Global Warming Upsets Religious Believers

Calgary Herald columnist and editorial page editor Licia Corbella wrote this article about the presentation by Dr. Ross McKitrick at the Friends of Science 11th annual luncheon at the Metropolitan Conference Centre in Calgary, Alberta on May 13, 2014. McKitrick showed "how the gap is growing wider and longer between what global warming models predicted and what has actually happened to the world’s climate." This discrepancy has major policy implications.



Dr. Judith Curry US Senate Testimony on Climate Change

Climatologist Dr. Judith Curry presented this testimony to the US Senate Committee on Environment and Public Works. She says "Multiple lines of evidence presented in the recent IPCC 5th assessment report suggest that the case for anthropogenic warming is now weaker than in 2007. For the past 16 years, there has been no significant increase in surface temperature. There is a growing discrepancy between observations and climate model projections. Observations since 2011 have fallen below the 90% envelope of climate model projections. The IPCC does not have a convincing or confident explanation for this hiatus in warming. CO2 is not a control knob that can fine tune climate."



Testimony of Dr. John Christy on Climate Science March 29, 2017

Technical Rating: star
Dr. John Christy gave this testimony to a hearing of the Committee on Science, Space and Technology of the US House of Representatives on 29 March 2017. He writes " When the “scientific method” is applied to the output from climate models of the IPCC AR5, specifically the bulk atmospheric temperature trends since 1979 ..., I demonstrate that the consensus of the models fails the test to match the real-world observations by a significant margin. He recommends the Congress to "fund credible “Red Teams” that look at issues such as natural variability, the failure of climate models and the huge benefits to society from affordable energy, carbon-based and otherwise."



The Canadian Climate Model's Epic Failure

Technical Rating: star
The Canadian climate model CanESM2 produces one of the most extreme warming projections of all the 30 models evaluated by the IPCC. The model badly fails to match the surface and atmosphere temperature observations, both globally, regionally. The mid-troposphere (400 mbar) global model temperature warming rate (1979 to 2015) is 287% of the weather balloon trend, and 532% of the satellite trend. The mid-troposphere (400 mbar) tropical (20 N to 20 S) model warming rate is 447% of the average of the satellite and balloon observations. This is an updated report to include 2015 data.
