Record of the concentration of CO2 in the atmosphere

The presence of the main gas causing climate change in the atmosphere continues its unstoppable climb. The observatories of Izaña (Tenerife) and Mauna Loa have detected in recent weeks concentrations of carbon dioxide (CO2) greater than 415 ppm (parts per million), what is a new record. You have to go back three million years to find such a high data. Never has human life developed under these conditions.

On April 18, the concentration observed by Izaña reached 416.7 ppm while in Mauna Loa it reached the ceiling on May 12 with 415.39 ppm. It is not ruled out that new records may be produced in the coming weeks, given that April and May are when the greatest upswings occur.

The data confirm that the growth of the presence of carbon dioxide not only does not slow down but keeps its accelerated pace. Izaña data reveal that the increase in CO2 concentration has passed in recent years from 1.8 ppm / year in the late 1980s to 2.3 ppm / year today, according to the State Meteorological Agency, attached to the Ministry for Ecological Transition.

The United States Oceanic and Atmospheric Administration (NOAA), which administers the Hawaii Observatory, has confirmed that Three of the four largest increases in atmospheric CO2 have occurred in the last four years.

The last time the Earth's atmosphere contained as much CO2 as it was now more than three million years ago, when the global level of the sea was several meters higher and parts of Antarctica were covered in forests.

In pre-industrial times, CO2 was at an average of 200 ppm, while scientists considered it safe not to exceed 350 ppm. So that the planet does not heat more than 1.5ºC, in line with the Paris Agreement against climate change, the 450 ppm should not be exceeded, a figure that would be reached by 2035 to follow the current progression.
