An analysis of atmospheric carbon dioxide carried by the wind from China on an island in Okinawa suggests that economic activity in China had returned to pre-impact levels in January. Published by the National Institute for Environmental Studies.
The National Institute for Environmental Studies and the Japan Agency for Marine-Earth Science and Technology are analyzing the composition of the atmosphere on the islands of Okinawa Prefecture. It is said that it is possible to estimate the economic activity of.
As a result of the analysis, the ratio of carbon dioxide decreased by 20% to 30% from the same month of the previous year in February and March last year when the movement of people was restricted in a wide range of China as a countermeasure for the new corona. It was believed that this was due to the stagnation of China's economic activity.
However, about a year later, when the atmosphere from January to March was analyzed, it was found that it had returned to the level before the influence of the new corona compared to the average value of past observations. That is.
This tendency has also been pointed out by surveys of statistics such as oil consumption, and this data is said to reinforce this.
Yasunori Toshima, director of the National Institute for Environmental Studies, said, "It was confirmed that it returned to the original level in just one year. The amount of carbon dioxide is important data in the discussion of global warming, so we will continue the investigation. I want to. "
