GHG's influence can explain climate change. GHG are transparent to sunlight but they absorb the earth radiation. Therefore, if this increases, the thermal energy accumlates on the earth's surface. Numerical models such as ESM calculate how the atmosphere, grond surface and ocean will share and absorb this amount of heat that has accumulated on the earth. The accumulation of heat in the atmosphere causes global warming, and the warner atmosphere can hold more water vapor, leading to an increase for heavy rain and snow events.
The global average temperature will stop rising if we no longer emit GHG, mainly carbon dioxide. However, once carbon dioxide is emitted, it remains in the atmosphere long time, so although the global average temperature may stop rising, it will not return to its original state. The amount of carbon dioxide that is allowed to be emitted by +1.5C post-industrial temperature rise is small, compared to the amount already emitted. If we can reduce GHG emissions rapidly and sustainably, we will wee the effect of it within the next 20 years. This time lag is because it takes time for the ocean's tempetarute to change. Also, it takes time for trend signals to emerge from the fluctuations of natural variability. All of this suggest us that it is important to take immediate action to stop global warming.
Using these results, we can show the hazards to various creatures living on earth. In this presentaiton, we will be able show you some of the changes, such as changes in the habiatble zone of beech forest, which are endemic to Japan, and changes in the migration timing of migratory birds. However, in order to consider what kind of risks these pose to society, we need an additional group of people known as lnowledge brokers. In that regard, I have high expectations for members belonging to
Geopark Japaan.
