Dr. David Shearman is the Honorary Advisor to Doctors for the Environment Australia and Emeritus Professor of Medicine at Adelaide University.
His article published in ABC News responding to continued proclamations by climate change deniers supporting the coal industry is found at the following web address.
A short excerpt from this article is as follows:
"Climate change denial prevents effective action on emissions, and leads to other lies and evasions by our leaders who support big coal and other polluters. Our government hit a new low point this week, by admonishing those who care."
"The collapse of our civilisations'
Climate change delusion is dangerous to humanity, for it overtly or deviously prevents effective reduction of greenhouse emissions by governments in many countries, including the US and Australia, but is an increasing problem with the rise of right-wing governments in Europe and South America, including, Brazil where the new government has a foreign minister devoted to climate denial.
Dangerous, for it is responsible for thousands of deaths worldwide from fire, flood, drought and hunger and a range of other causes including infections.
These deaths are projected to rise to 250,000 by 2030. In Australia the existing and expected health impacts are well documented and already affect our health services.
In the words of David Attenborough at C0P24:
"Right now, we are facing a man-made disaster of global scale, Our greatest threat in thousands of years, climate change... If we don't take action, the collapse of our civilisations and the extinction of much of the natural world is on the horizon."
