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.

The Global Warming Hiatus

Technical Rating: star
While the Intergovernmental Panel on Climate Change (IPCC) still uses the iconic word “unequivocal” to describe warming of the climate system over the past century, a new word has slipped into its lexicon: the “hiatus.” They have begun referring, with a bit of hesitant throat-clearing, to “the warming hiatus since 1998.” Cracked-beakerBoth satellites and surface records show that sometime around 2000, temperature data ceased its upward path and leveled off. Over the past 100 years there is a statistically significant upward trend in the data amounting to about 0.7 oC per century. If one looks only at the past 15 years though, there is no trend.

A Sensitive Matter: How the IPCC Buried Evidence

Technical Rating: star star
The IPCC's recently published report suppressed evidence that the climate is much less sensitive to greenhouse gases than indicated by climate models according to this report by Nicholas Lewis and Marcel Crok. The report says, "In AR5, many studies still use inappropriate data and/or statistical methodology. However, there is now a body of empirical estimates of climate sensitivity, prepared using sound methodology and appropriate data, that give substantially lower values - than climate model simulations." Estimate of the cooling effects of aerosols have been cut, which reduces the estimate of greenhouse gas warming, but this is not included in climate models.

IPCC Models Getting Mushy - McKitrick

Technical Rating: star
Dr. Ross McKitrick writes in the Financial Post "In the next five years, the global warming paradigm may fall apart if the models prove worthless". The IPCC graph comparing models to observations show the models significantly over-predicted the warming effect of CO2 emissions for the past 22 years. There is even a larger discrepancy in the atmosphere over the tropics. The UN IPPC panel is in full denial mode. They claim there is no discrepancy. McKitrick says, "The IPCC must take everybody for fools."

Climate Models Fail to Match Recent Temperature History

Technical Rating: star
A team of prominent climatologists finds that the continued global warming stagnation over fifteen years, from 1998 to 2012, is no longer consistent with model projections at 98% certainty. Temperatures in the past have changed up to 24 times faster than the 20th century warming. The modeled warming trend since 1979 in the tropical mid-troposphere is four times greater than measurements.
