CO2 absorption by coral reefs 1999.11.15

As a result of observations by professors from the University of Tokyo on Ishigaki Island, Okinawa Prefecture, we found that the CO2 absorption and release of coral reefs fluctuates during the season and day and night. On a daily basis, the photosynthesis of phytoplankton that coexist with corals absorbs CO2 by day, and the discharge by breathing is predominant at night. In the season, the release was noticeable in the summer, and the winter was absorbed more often. Over the years, coral reefs tend to absorb CO2.

Deforestation also contributes to global warming 1999.11.15

The Meteorological Institute of Japan Meteorological Agency has identified the possibility of large-scale forest fires in the tropics to contribute to global warming. From 93 to 6 years, the result of collecting and investigating the air on an airliner between Japan and Australia recorded a co concentration of 380PPB, which is nearly 10 times the most normal in the northern Australia between the fall of 1997 and the spring of 1998. The concentration pattern when the plant burns is detected, and it is found that the CO2 generated by the Indonesia forest fire at the same time.

Ozone hole moves to Hokkaido area 1999.11.15

A joint study between the National Institute of Environmental Studies and Nagoya University revealed that part of the ozone hole over the Arctic had been southward to the sky in the spring of 1996, in the Air balloon observation. The air flow around the Arctic is unstable, and it is often said that some of them may be torn apart and moved to the middle latitude area, but the ozone depletion has been numerically confirmed in the Japan sky. The possibility of such an ozone hole coming to the Japan is high in the future.
