According to The Economist, The Heartland Institute is “the world’s most prominent think tank promoting skepticism about man-made climate change.” On Wednesday, several scientists gathered at the institute’s 9th International Conference on Climate change to address a variety of issues including the biological effects of increased CO2 on the planet due to human activity.
Dr. Craig Idso, the founder, former president, and current chairman of the board of the Center for the Study of Carbon Dioxide and Global Change, provided a plethora of information on exactly how CO2 affects the environment. Global warming alarmists should be comforted that they have a lot more to be happy about and should not be fretting that global catastrophe is knocking at the door.
Idso pointed out that there is a huge body of literature on the biological impacts of rising temperatures and atmospheric CO2 levels that the International Panel on Climate Change (IPCC) ignores. He emphatically stated that atmospheric CO2 is not a pollutant. In fact, increased levels of CO2 reduce the negative effects of a number of plant stresses including: high salinity, low light, high and low temperatures, insufficient water, air pollution, and protects against herbivores i.e. being eaten by animals and insects.
Notably, Dr. Idso emphasized that the increased CO2 levels allow plants to produce the same amount of crop yield with less water. Moreover, plants are able to grow in dry areas where it had been previously too dry to exist. A collateral benefit to this is that the increased vegetation reduces the effects of soil erosion.
Perhaps Idso’s final conclusion should make all those who fear that global warming and increased CO2 is adding to the demise of the planet that everything is going to be OK: he claimed it is far more likely that CO2 proliferation will increase regional biodiversity and will contribute to the expansion and proliferation of animal habitats.
