Dr Patrick Moore cofounder of Greenpeace says humans have reversed the 150 million year decline of CO2 in earth atmosphere

    Dr Patrick Moore has criticised a new study reported in the New Zealand Herald on 11 July which said that global warming has been slowed by an increase in CO2 absorption by plants.     The new study headed by Dr Sara Mikaloff-Fletcher from the National Institute of Water and Atmospheric Research claimed that  because of this unexpected absorption the earth would have warmed faster.  However Dr Moore commented to ClimateDepot.  " these people are either completely naive about the relationship between CO2 and plants or they are making this up as a way of deflecting attention from the lack of warming for the past 15 years"   He goes on to say " plants grow much faster when CO2 is higher, the optimum concentration is between 1500-2000 ppm so there is a long way to go before plants are happy.   CO2 levels in the atmosphere have continued to rise despite plants absorbing more CO2.  So what is the scientist`s point?   It is to obfuscate, confuse, and otherwise muddy the waters with disinformation."   He continued "we should challenge them to admit that CO2 is the most important nutrient for all life on earth and to admit that it is proven in laboratory and field experiments that plants would grow much faster if CO2 is the most important nutrient for all life on earth and to admit that it is proven in lab and fields experiments that plants would grow much faster if CO2 levels were 4-5 times higher in the atmosphere than they are today.  Greenhouse growers pipe the exhaust from their gas and wood heaters back into the greenhouse to increase CO2 levels 3-5 times the level in the atmosphere, resulting in 50-100% increase in growth of their crops.   And they should recognize that CO2 is lower today than it has been through most of the history of life on earth.  There is no abrupt increase in CO2 absorption, it is gradual as CO2 levels rise and plants become less stressed by low CO2 levels.  At 150 ppm CO2 all plants would die, resulting in the virtual end of life on earth".   Referring to humans he said" thank goodness we came along and reversed the 150 million year trend of reduced CO2 levels in the global atmosphere."
