We have been conditioned with the belief that human activities are increasing the incidence of CO2 and other greenhouse gases into the atmosphere, which is the prime cause behind global warming and climate change. We are also led to believe that science is predicting that the consequences of this will be catastrophic to the earth and threaten our very existence.
Most of what we read within the mainstream media today, and from the politicians, has the above assumptions subliminally embedded within the various narratives. Government policy towards carbon emissions and renewable energies reflects these beliefs, as hard caste scientific and moral truths.
The public are continually told that the vast majority of the world's "scientists" are in general agreement about man-made global warming being the cause of climate change, and the potential damage it will do to the earth. However, the reality is that there may actually not be more than a couple of hundred people in the world who really understand the science of climate change, and are experienced and qualified enough to make a valid scientific opinion.
The public are confused more when evangelists from both sides of the debate put their views forward using statistics, information, and arguments that are convincing. Many of these stalwarts on both sides make a professional living through the speakers' circuits, turning the global warming and climate change debate into an entertainment spectacle. What makes this even more sinister, is the vested interests some of these parties represent.
Climate change models are built upon limited sets of assumptions which make them far too simplistic for the task of making accurate predictions about global warming. There is no generally agreed theory that explains global warming and climate change in existence today.
No model can predict changes in temperature, and layout climate change scenarios with any degree of accuracy. However the earth has warmed up much less than what most global warming models had predicted.
The opinion of Nobel Prize winner James Lovelock, the creator of the GAIA hypothesis, reflects the above.He was quoted as saying….."The problem is that we don't know what the climate is doing. We thought we knew 20 years ago. That led to some alarmist books – mine included- because it looked clear-cut, but it hasn't happened."
Rachel Carson's book Silent Spring also predicted that all the birds would be killed through the use of DDT during the 1950s and 60s – a prophecy that never happened.
Alarmism clouds scientific judgement and this is very much the case in the global warming and climate change debate.
Global warming and climate change cannot be considered a 'settled science', as it is portrayed today. The truths about the matter are still yet to be understood.
First it must be understood that global warming and climate change are not interchangeable terms. Global warming concerns the rise in average temperatures across the globe. Is this really occurring? And, how much is humanity actually responsible for this phenomenon?
These are very interesting scientific questions where there is a diverse range of scientific opinions today. We still require answers to tackle the second part of the equation, climate change.
