Carbon dioxide is the main cause of human-induced climate change. It has been emitted in vast quantities from the burning of fossil fuels and it is a very long-lived gas, which means it continues to affect the climate system during its long residence time in the atmosphere.
The cause of global warming is human activity, specifically the burning of fossil fuels which releases millions of tons of carbon dioxide into the atmosphere every year.As the amount of carbon dioxide increases in the atmosphere, more of the sun's radiant energy is trapped as heat, causing global warming.Other activities that are contributing to global warming include massive deforestation projects and the emission of methane and several other air pollutants.he cause of global warming is human activity, specifically the burning of fossil fuels which releases millions of tons of carbon dioxide into the atmosphere every year.
