The Earth has warmed – and cooled – over the past 50 years. We’ve also experienced periods of “unusual” weather and “normal” weather, more frequent and intense storms and droughts, less frequent and less severe storms and droughts. However, I don’t agree that humans are responsible, or that climate change is becoming dangerous or catastrophic.
CO2 is a trace gas, but without it life on earth would be impossible. Carbon dioxide fertilizes aglae, trees and crops to provide food for humans and animals. We inhale oxygen and exhale CO2. Slightly higher atmospheric CO2 levels cannot possibly supplant the numerous complex and inter-connected forces that have always determined Earth’s climate.
As University of London professor emeritus Philip Stott has noted: “The fundamental point has always been this. Climate change is governed by hundreds of factors, or variables, and the very idea that we can manage climate change predictably by understanding and manipulating at the margins one politically-selected factor (CO2), is as misguided as it gets.”
Even the global warming activists at RealClimate.org acknowledged this where they said “The actual temperature rise is an emergent property resulting from interactions among hundreds of factors.” CO2 is not the tail that wags the dog.
