An American report: The Earth has reached a state of pollution not recorded for 4 million years!

The concentration of carbon dioxide in the atmosphere, last May, reached a level 50% higher than it was during the pre-industrial era, and it has not been previously recorded on the planet for about four million years;

According to the US National Oceanic and Atmospheric Administration.

The administration explained that the reason for this new rise is global climate warming caused by human activities, the most important of which are transportation, cement production, deforestation and the production of electricity using fossil fuels.

May is usually the month in which each year the highest levels of carbon dioxide are recorded;

Where the concentration of carbon dioxide in May 2022 exceeded the threshold of 420 parts per million “ppm”, which is the unit of measurement used to determine the amount of pollution in the air, while in May 2021 this rate was 419 parts per million, and in 2020 it was 417 parts per million.

These measurements are taken by the Mauna Loa Observatory in Hawaii;

Where this observatory was built on a high site;

This avoids being affected by local pollution.

The Oceanic and Atmospheric Administration explained that the level of carbon dioxide was constant before the industrial revolution at about 280 parts per million, and it remained that way during the preceding period of about six thousand years.

The administration indicated, in a statement, that the level recorded today is close to that which existed "4.1 to 4.5 million years ago, when carbon dioxide levels were about 400 parts per million or more."

At that time sea level was between five and 25 meters higher than it is today, and vast forests existed in parts of the Arctic;

According to studies.

Carbon dioxide is one of the greenhouse gases that contribute to heat trapping;

This is gradually causing global warming, and it remains in the atmosphere and oceans for thousands of years.

The Department of Oceanography and Atmosphere reminded that this warming is beginning to lead to dire consequences, including the proliferation of heat waves, droughts, fires and floods.

Researcher Peter Tans of the Atmospheric Administration noted that "the human race has never known such levels of carbon dioxide as exist today."

He added: "We've known about this for half a century and have failed to do anything. What do we need to wake us up?"
