If the growth rate of carbon dioxide remains the same, the temperature in Japan...

The diagrams below display the Japan's distribution of temperature changes showing the difference in calculations of future world temperatures by computer based on the following two scenarios.

  • Carbon dioxide discharge levels continue to rise every year (1% per year)
  • Future carbon dioxide discharge levels remain as they are today.

With carbon dioxide discharge levels gradually creeping up as they have been,

  • the more red a region is,the more warming is amplified,
  • and regions coloured in blue will experience delayed warming due to the increase in carbon dioxide discharge levels.

The colors and numbers shown below relate to temperature change.
For example, red indicates a temperature change of 5 to 6 degrees Celsius.

In this manner, in Japan, the scenario where we continue to increase carbon dioxide discharge levels year by year results in increased warming compared to the scenario where future carbon dioxide discharge levels remain at present levels.

Thinking about the trends mentioned above in reverse,

The temperature rises shown in these diagrams can be prevented simply by stopping the current upward trend in the amount of yearly carbon dioxide emissions, and ensuring emissions don't supersede current levels.
