“Atmospheric CO2 levels have risen from about 250 parts per million (ppm) around 1750 (roughly the end of the Little Ice Age) to 400 ppm today. In the earth’s geologic past, CO2 levels were often much higher than they are now, without any runaway greenhouse effect. We are fortunate to be living in an interglacial period – meaning we’re living between the last Ice Age and the next one – and higher levels of CO2 are to be expected and, when it comes to agricultural productivity, to be welcomed.“
By Bonner Cohen, Ph.D. ~
A constant refrain of climate alarmists and “clean-energy” business eager to cash in on the scare is that the use of fossil fuels to create energy is endangering the climate by overloading the atmosphere with manmade greenhouse gases.
This, we are told, is responsible for rising sea levels, floods, droughts, hurricanes, tornadoes, extinction of species, spread of infectious diseases – the list goes on. Over time, greenhouse gases have been rebranded as “carbon pollution,” just as global warming now bears the label “climate change.”
Of all the noxious substances we are said to be putting into the air, none is viler that carbon dioxide, CO2. In the name of reining in this alleged killer, we subsidize intermittent wind and solar power and provide tax credits to the mostly well-heeled buyers of electric vehicles. We blanket the countryside and seacoast with giant, bird-and-bat-killing wind turbines and…
