Antarctica: CO2 density is record high after 4 million years

This is the first time Antarctica has reached a record CO ₂ in the atmosphere, up to 400 parts per million (ppm), something that has never happened in the coldest continent in the world for the past 4 million years.

The amount of carbon dioxide in the atmosphere has increased rapidly since pre-industrial times so far. It is worth noting that this number is continuously higher year by year.

When the amount of carbon dioxide in the atmosphere averaged over 400 parts per million (ppm), the safety threshold set by people three years ago, it is still hoped that the far-flung continent of South Vietnam. The pole will escape the danger of CO ₂ covering other continents.

The atmospheric CO ₂ concentration measured at the Antarctic Observatory exceeded 400 ppm on May 23.

However, climate change and global warming phenomenon do not seem to excuse any place on this planet.

Antarctica has reached the limit of the planet

According to the latest announcement by the American Oceanic and Atmospheric Administration (NOAA), atmospheric CO ₂ concentrations measured at the Antarctic Observatory exceeded 400 ppm on May 23. This is the record concentration of CO2 in the atmosphere for the first time in the last 4 million years in Antarctica.

It is known that the amount of CO2 in the pre-industrial atmosphere only fluctuates around 280 ppm. More than a century later, this number has increased to more than 120 ppm and reached 400 ppm in 2013. It is not surprising that human fossil fuel consumption itself has become the main cause. so the change is strong.

Average CO2 content in Antarctica for several years.

According to IFLScience, there is always a certain delay for CO ₂ to cover the entire planet's atmosphere. Most CO ₂ pollution comes from the Northern Hemisphere, where most of the world's population is concentrated. That is why the 400 ppm milestone was recorded in the Northern Hemisphere a long time ago.

Carbon monitoring scientist at University of Environmental Science (ESRL). California, USA, Pieter Tans said: "The increase in CO ₂ concentrations is happening everywhere, even in remote areas can feel this impact. If you emit CO ₂ in New York, a part of CO ₂ which will soon cover Antarctica next year ".

The concentration of CO ₂ in the air exceeds 400 ppm once again is a warning and reminder to all humans. We have seen sea level rise in the past 120 years and the temperature has increased by an average of about 1 degree Celsius globally.

According to ClimateCentral, Arctic sea ice has fallen 13.4% per decade since 1970. Popular high temperatures and ocean acidification are slowly pushing many aquatic species into extinction.

Describe the movement of CO ₂ on Earth.

A recent finding shows that about 95% of the coral reefs at Jarrvis Island, the South Pacific Ocean have died after mass coral bleaching. The main reason is due to the extreme impact of El Nino phenomenon and the general acidification status.

Although the latest Agreement on Climate Change has been adopted in Paris, France in December 2015, and then signed by 175 countries and territories in April 2016. However, all efforts will not be enough if countries do not have a mechanism to monitor and cut CO2 emissions in the future.

That is also why meteorological stations in the southernmost region of the Earth will still provide the most accurate assessment of Earth's current climate change.
