Specialists have recently announced that the Earth passed the last recorded carbon dioxide level of 400 parts per million. The result was reported for September, the month when generally low rates of carbon dioxide are registered. Experts believe that Earth will not recover soon from this hit and that the level of CO2 in the atmosphere won’t drop during our lifetime.
The 400 parts per million label is not quite ideal itself. According to previous research, it was first registered three years ago, at a specialized Observatory in Hawaii. At the time, specialists considered it to be an alarming level and intended to take action. However, the rate of air pollution is still high.
Specialists predict that the following months will display a similar level of carbon dioxide in the air. September was supposed to bring a drop in the statistics because plants have been active all summer replacing CO2 with oxygen, and now they are decomposing. It seems that the natural phenomena are also overwhelmed by the man-made facilities.
Researchers estimate that no significant change will be visible in the next years. This is because carbon dioxide can last in the atmosphere even for millennia. As opposed to CO2, methane is a gas which only lasts in the air for a short period, but it is still damaging because it contributes to the acceleration of the process of global warming.
Experts say that a 400 ppm level of CO2 was also reported more than three million years ago. However, back then climate conditions were different than those that we are dealing with today. The processes of accumulation and dropping of the CO2 levels in the atmosphere take time. For instance, before the industrialization age, there was 280 ppm in the air.
What researchers are worried about is not the natural processes of gas accumulation, but the human activities which interfere with them. In just a few hundred years, massive industrialization and modern technology created by man severely affected the natural environment, to the point shown by statistics today.
Some of the specialists believe that, as far as monthly levels are concerned, none will be below 400 ppm from now on. They also took into consideration the hypothetical case of the zero production of CO2, and even so, the atmosphere will still be polluted for several years.
Scientists talk about two ways of solving this problem. One is that of cleaning the environment, while the other is preventing further CO2 accumulations.
