Antarctic Ice Shelf Collapse: Be Careful With The Blame Game
Reading the mainstream news today it is easy for the layman to assume that the case for reducing Co2 emissions to combat climate change is complete. These beliefs tend to be enforced by daily stories in the world’s media blaming global warming for every natural disaster or instance of unusual weather.
The danger is that we allow these beliefs to go unchallenged, and fail to exercise proper caution whilst we spending trillions of dollars to reduce the world population’s carbon footprint.
A study published this week by Neil Glasser of Aberystwyth University and Ted Scambos of Colorado University demonstrates this point, claiming that contrary to popular reporting and widespread belief, climate change was not the only cause of the collapse of a 500bn tonne ice shelf in Antarctica six years ago.
The study points to a combination of glaciological and atmospheric factors combined with the fact that the shelf had been on the brink of collapse for decades as significant contributors to the collapse of the 200 meter thick, 1,255 square mile ice shelf in 2002.
The evidence for man made global warming is indeed powerful, but not fully conclusive. Despite large numbers of crack-pot theories, there is a very credible body of scientific research which suggests we should exercise caution in our belief that Co2 causes climate change. It would be tragic indeed if, after investing trillions of dollars dramatically reducing or Co2 output, the world wakes up one morning to find that the climate and our environment are changing anyway.
Glasser and Scambos study is a useful reminder that our policy decisions need to be based on facts and solid research, not merely on unchecked beliefs.

And then there’s the fact that significant climate change has occurred in the past, in very short periods of time, without the influence of man’s CO2 emissions.
