However , the fact that near-surface temperature has rapidly increased on the global scale in the past few decades can hardly be accounted for by natural processes . In reality global warming is to a great extent caused by human activity , which has been proven by extensive scientific research (UN Environment Program By burning coal , natural gas and oil , introducing harmful agricultural practices and destroying forests people make a significant negative impact on the state of the atmosphere , altering its composition irreparably .
