The amount of ozone-harming carbon dioxide (CO2) in the environment is higher today than at any time in recent past three million years, as per the study.
Researchers from the Potsdam Institute for Climate Impact Research in Germany prevailing to do a computer simulation that fits sea floor residue information of climate change over this time. The research discovered that ice age onset, and the beginning of the glacial cycles from cold to warm and back, was essentially activated by a reduction of CO2 levels.
Today, it is the expansion of ozone-depleting pollutant because of the consumption of non-renewable energy sources that are changing our planet.

On May 9, 2013, CO2 levels in the air reached the level of 400 parts per million (ppm). Today, worldwide mean temperatures never surpassed the preindustrial levels by more than 2 degrees Celsius in the previous three million years, as per the study. There is no doubt that soon sea level will increase, extreme temperature, hotter temperature, more climatic events. As per NASA, CO2 levels have risen from 317 ppm in 1958 to 400 ppm today and are projected to reach 450 ppm by the year 2040.
