Coming months in Pakistan, especially in plains will be very hot. As per previous experience the condition might be miserable for livings. In 1827, a French mathematician, JOSEPH FOURIER was the first to suggest that there might be a link between the quantity of CO2 in the air and the temperature. New research suggests that the weathering of rocks in high mountains like Himalaya and Karakoram takes the carbon dioxide out of the atmosphere. The CO2 reacts with some types of rocks and is carried down by the rivers and end up at the bottom of the sea. In short we must take all the measures to reduce the intensity of hot weather and to save us from global warming.
