‘It is difficult to get a man to understand something when his salary depends upon his not understanding it.’

Upton Sinclair

All scientists are skeptics who love to disprove theories and add new facts to existing theories before finally coming to an agreed understanding.

For scientists to arrive at these understandings many papers are written then added to by others, clarified, checked, peer reviewed by other scientists, rewritten and debated. When the conclusions are eventually agreed upon, then this becomes the science – the accepted and agreed upon knowledge of that time.

When the facts change the science changes.

Peer-reviewed science is a bit like a big family deciding which movie to rent online – you really have to make your case strongly and clearly with the correct facts to get your movie selected.

The science on climate change tells us that there is a 97% chance that the current climate change is being largely caused by human activity.

Some scientists argue for the 3% chance that humans have had no impact on our climate. They are skeptical of the accepted science, and they argue and engage in debate that this is simply a natural occurrence. This is how science works.

There are a handful of so-called deniers in the science community who have chosen not to be a part of the debate on climate change. They are not peer-reviewed scientists but still have more to say than most. There are also media commentators and the rich business people that employ them who cannot stand the idea that our idea of progress is destroying our life support system – our natural world.

Their outlook on life and their perception of the world cannot accept that human activity should be regulated or even scaled back by laws. They have an everyman for himself approach that favours the rich and powerful. They do not favour government regulation that would stop Big Polluters because it would mean changing the way they operate.

These so-called deniers are not offering scientific facts for debate; they are merely offering their own opinions. They are pushing for the 3% chance that humans are not accelerating the current changing climate. They are entitled to their own opinions but are they entitled to their own facts?
