Earth's carbon dioxide concentration records the highest ever observed

Carbon dioxide is one of the greenhouse gases and is considered to be a major cause of global warming. It is clear from the data of Mauna Loa Observatory on the island of Hawaii that the carbon dioxide concentration on the earth has finally reached 415 ppm, which is the highest ever observed .

According to data from the Mauna Loa Observatory, which has been observing changes in greenhouse gases and so on for a long time, the carbon dioxide concentration on May 11, 2019 was 415.26 ppm. This is the highest figure since the observation of carbon dioxide concentration started, and it can be seen that the carbon dioxide concentration on the earth has been the highest in the past several million years.

In the news that the concentration of carbon dioxide on Earth has exceeded 415 ppm, weather reporter Eric Holthaus says, 'This is the highest value since modern humanity appeared millions of years ago.'

This is the global change in carbon dioxide concentration announced by the Japan Meteorological Agency . The red line is the concentration without seasonal variation, and the blue line is the average monthly concentration. Although it was less than 350 ppm in 1985, it seems that Gungun and CO2 concentration are rising, showing a sharp upward trend.

Looking at the span of the past 10,000 years, we can see that the concentration of carbon dioxide, which has been below 300 ppm for many years, has risen sharply in the last few hundred years.

The impact of humanity on the earth's environment is increasing year by year, which can cause serious problems. In May 2019, the report “One million species of animals and plants are in danger of extinction due to human activities” was issued by the Intergovernmental Organization on Environment “The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES ) it was announced by '.

According to a report by the US government, if it does not take measures against global warming as it is, it is estimated that the cost of loss caused by climate change will reach about $ 500 billion in 2090 (about 55 trillion yen) . Greenhouse gases such as carbon dioxide also play a role of maintaining the temperature at which life can be maintained, but if the concentration is too high, efforts to reduce carbon dioxide emissions will have a major impact on the entire ecosystem. Is urgently needed.
