Western Spruce Budworm Outbreaks in Central British Columbia (15 May 2015)
New research demonstrates that this current scourge of the Canadian province is not the result of what climate alarmists consider to be concomitant unprecedented global warming, but rather a recurring phenomenon with a mean return interval of approximately 30 years that has been in play for at least the past four and a half centuries...

Climate Model Inadequacies (Soil Moisture) -- Summary (14 May 2015)
