The molecular weight of carbon dioxide, which we are told is a ‘greenhouse gas’ is just over 44 while that of air is 29.
How then can carbon dioxide can rise 12 miles into the atmosphere to become a ‘greenhouse gas’ when it is heavier than air?
Earth’s climate has always changed over eons of time and the major influence was obviously the sun’s activities.
Meterorite strikes have had effects such as that on Yucatan, Mexico which decimated dinosaurs due to dust in the atmosphere obscuring the sun.
When Mount Krakatoa exploded the resulting dust changed the climate for several years.
Carbon dioxide is not a pollutant. It is however essential for the growth of plants. It is pumped into commercial greenhouses to grow bigger tomatoes. NASA photos from space show vegetation advancing into the southern fringe of the Sahara desert. Carbon dioxide renders plants stronger and more able to resist harsh conditions.
Will the carbon reduction agenda result in lower crop yields?
