"Crisis or Hoax" is intended for readers with a strong interest in climate change and environmental protection, but who do not accept everything published by the media at face value. Many recent publications stress that climate science is not "settled" and that experimental proof remains insufficient. Scientists grapple with a " double ethical bind", a concept that appears to defend and promote alarmist misinformation. The author identifies a discernable anthropogenic global warming trend over the last 150 years - known as the Modern Warm Period - but questions the recent conclusions of the Intergovernmental Panel On Climate Change (IPCC) which attributes most global warming to human emission of greenhouse gases. Most of the trillions of dollars spent on the mitigation of CO2 might be wasted; adaptation to climate change - warming as well as cooling - is a better option. The book offers an unbiased perspective on climate science, explains the intensive conflicts between alarmists and skeptics and presents suggestions for climate policy that can be effective without harming the economy. The book is intended for readers with a strong interest in climate change but who question mainstream media narrative and prefer to draw their own conclusions. The author studied physical geography and climatology and was a Member of Parliament in the Netherlands.
