Greenpeace co-founder Dr. Patrick Moore pens treatise on the positive effects of CO2 – says there is no crisis
We should ask those who predict catastrophic climate change, including the UN’s Intergovernmental Panel on Climate Change, some pressing questions regarding the outcome if humans had not intervened in the carbon cycle.
- What evidence or argument is there that the global climate would not revert to another glacial period in keeping with the Milankovitch cycles as it has done repeatedly during at least the past 800,000 years?
- What evidence is there that we are not already past the maximum global temperature during this Holocene interglacial period? • How can we be certain that in the absence of human emissions the next cooling period would not be more severe than the recent Little Ice Age?
- Given that the optimum CO2 level for plant growth is above 1,000 ppm and that CO2 has been above that level for most of the history of life, what sense does it make to call for a reduction in the level of CO2 in the absence of evidence of catastrophic climate change?
- Is there any plausible scenario, in the absence of human emissions, that would end the gradual depletion of CO2 in the atmosphere until it reaches the starvation level for plants, hence for life on earth?
These and many other questions about CO2, climate and plant growth require our serious consideration if we are to avoid making some very costly mistakes.
