Carbon dioxide levels have reached their highest levels ever

The world is in total change and there are worrying numbers such as carbon dioxide levels. Despite all the calls for a “greener world”, countries continue to ignore the state of the planet and the results leave no room for doubt.

Last May, carbon dioxide levels reached the highest levels ever for humanity.

Carbon Dioxide: Before the industrial revolution, the CO2 level was around 280 ppm

The amount of planet-warming carbon dioxide in the atmosphere has passed a major milestone (more than 50% above pre-industrial times), the National Oceanic and Atmospheric Administration (NOAA) warned on Friday. The organization pointed out that these levels had not been recorded for millions of years.

Human-caused global warming - with fossil fuel electricity production, transport, cement production or deforestation - is responsible for this phenomenon, the US agency said.

In May 2022, the threshold of 420 parts per million (ppm), the unit of measurement used to quantify air pollution, was exceeded. In May 2021, this rate was 419 ppm, and in 2020, 417 ppm.

Before the industrial revolution, the level of carbon dioxide was around 280 ppm during the approximately 6,000 years of human civilization that preceded it, according to NOAA.

The level achieved today "is comparable" to what it was "between 4.1 and 4.5 million years ago, when CO2 levels were close to or above 400 ppm," the agency said in a statement.

Sea level at the time was 5 to 25 meters higher, enough that many of today's large cities were submerged.

Carbon dioxide is a chemical compound made up of two oxygen atoms and one carbon atom. The chemical representation is CO₂. Carbon dioxide was discovered by the Scotsman Joseph Black in 1754. Structurally, carbon dioxide is made up of molecules of linear geometry and non-polar character.
