In April of this year the earth reached the highest concentration of greenhouse gases in the atmosphere recorded since human beings inhabited it. The current record is 411 parts per million (ppm), in 1880 it was 280 ppm. These changes of gases concentration in the atmosphere has a direct impact on the temperature of the earth and its ability to maintain a balance in the environment.
The Paris Agreement has sought to unite all possible countries to carry out actions that can stop this temperature increase to only two degrees Celsius. However, even with that limit it is projected that there will be a loss of more than 18% of some species. In prehistoric times the concentration of these levels reached 700 ppm, but it was caused naturally. What is impressive now is how it has grown rapidly and by human activity.
