Carbon dioxide levels in air have reached the highest point. If the trend continues, everyone may have to wear respiratory masks to breathe in just 20 years from now.
According to the National Oceanic and Atmospheric Administration, the amount of carbon dioxide in the air was 411.25 parts per million. The Scripps Institution of Oceanography measured carbon dioxide at 411.35. This is the highest monthly level ever recorded by scientists. The scientists studying the greenhouse gases are of the view that this could also be the highest concentration of carbon dioxide in human history.
The problem with carbon dioxide is that each molecule of carbon dioxide may take, scientists say, hundreds or even thousands of years to finally dissipate. The carbon dioxide molecules are, in fact, self-powered tiny heat convectors that may keep warming the air and the seas for generations to come.
To understand the real issue with the latest rising trend in the greenhouse gas, it is imperative to underscore that the CO2 levels were stable at 280 ppm prior to the industrial revolution.
The climatologists say that if the current rate of rise in carbon dioxide levels continue, it would reach at 450 ppm in just 20 years from now. The companies manufacturing air-filters and protective gas masks would be the sole beneficiaries.
