The NOAA (National Oceanic & Atmospheric Administration) reported that CO2 levels worldwide have passed the 400ppm (parts per million) mark this March.
This is the highest concentration of CO2 in recent times. The excess burning of fossil fuels for transportation and industry use is the primary culprit. The CO2 global levels have seen a rise of 120ppm since the pre-industrial era.
This is raising concern amidst the already unstable environment, facing a global rise in water levels, melting glaciers, air-related diseases, temperature variations, etc.
The air samples were collected from 40 sites across the world.
