The relationship between global warming and CO2 emissions is similar to that of COVID19 infection and the vaccination. The use of fossil fuel is truly one factor in global warming, but not the determinant. Similarly, vaccination is a major factor in reducing infection and death, but not the only factor, as many other factors add up to determine the infection rates and symptoms.
地球温暖化とCO2排出の関係とコロナ禍でのワクチンの話はよく似ているね。化石燃料は温暖化のあくまで一因子であって全ての決定因子ではなく、同様に予防接種の有無はコロナ感染や死者数を決める大きな一因子ではあるけれど、それが全てではないからね
