Global cooling will come soon.

　My uncle is a meteorologist. So he wrote a paper about global cooling.He scrutinized Japanese glacier. Although huge increase of oil consumption,global climate was cooling in 60`s and 70's. I wondered a complex climate system.
CO2 was not a main factor of worming. When did it become to be the principal?
After all ,It is important for us to estimate the global thermal balance seat.Actually CO2 itself is a neutral position for global warming. Indeed the higher the temperature is ,the more CO2 exists in the air,but the contrary is not true. Depending on thermodynamics, increase of CO2 in the air cause cool summer. Keeping warm equal to keeping cool.
