CO2 Concentration Levels Are Now Permanently Above 400 ppm

The year 2016 is one of the saddest milestones in global warming, setting a record high carbon dioxide concentrations in the Earth’s atmosphere. Since the industrial revolution where the concentration was around 280 parts per million, this 400 parts per million mark is an unprecedented concentration we have ever reached.

Every year during the summer in the northern hemisphere, plants absorb this excess carbon dioxide by photosynthesis and try to reduce the concentration levels a bit. Humans usually hope for the best around the months of August, September, and October. With increasing concentrations due to fossil fuels and deforestation, we haven’t stopped upsetting the carbon cycle yet.

This year, it was believed that around September the concentration levels might be at its minimum, and possibly could go below the 400 ppm line. But thanks to our ignorance as a race, the hope is shattered now. We are still stuck above 400 ppm. Looking at the data of the past few years, it is evident that we are not going to return to the 400 ppm mark anytime soon.

We have already passed the time where we should be preventing deforestation. With alarming rates of global warming, it is now time to focus on afforestation and reforestation in an accelerated phase.

In 2017, the record high was 405 ppm.
