Is global warming real? And how reliable is the science behind the theory? Is the science “settled”? And is there a “consensus” among climate scientists that man-made climate change is underway?
Solid Waste & Recycling magazine Editor Guy Crittenden has attended a number of industry conferences in recent years at which various presentations were made about the value of recycling, composting and other waste diversion activities in reducing Canada’s contribution to “man-made global warming.”
Without claiming to know either way whether man-made global warming is real or occurring, Crittenden, who supports waste diversion and energy efficiency, recently became concerned that certain discussions have ignored recent developments that call into question the validity of certain data and assumptions used several years ago to convince policymakers that we are living in the warmest period in the Northern Hemisphere in the past 1,000 years, and that temperatures are set to rise rapidly. The United Nations-sponsored Kyoto Accord (signed and ratified by Canada) was the main outcome of the scientific findings, some of which have since been questioned and in some cases discredited in peer-reviewed journals such as Science.
There may be less of a “consensus” among scientists (including climatologists) in regard to this matter than is commonly assumed, or represented by the mainstream media. In order to raise awareness of this matter among waste management, recycling and composting professionals (who are increasingly interested in what this may mean for them) and for the purpose of stimulating informed discussion and debate among policymakers in Canada, Crittenden’s Editor’s Blog at the left side of the Solid Waste & Recycling magazine homepage (www.solidwastemag.com) offers fresh analysis of this issue along with mention of some useful Internet-based resources for further research and reading.
