No;global warming seems to be a man-made thing.Carbon dioxide is an important greenhouse gas which absorbs the IR radiation.It contributes about 12 percent to the greenhouse effect.It is estimated that the mean global temperature would have been about 33 degrees(celcius) less than what it is today if the greenhouse effect is not there.
Now it is a known fact that the amount of carbon dioxide in slowly increasing in the atmosphere.Cities make a heavy contribution to the gases which are considered responsible for global warming.An estimate shows that a city of one million people generates 25000 tons of carbon dioxide every day.
Moreover the population of the world is increasing alarmingly.The amount of carbon dioxide released by human beings while breathing also increases.At the same time the intake of carbon dioxide by the trees and plants(they require CO2 for their food preparation) is reduced as the forest area is diminishing (as we are destroying the forests).The net result is the increase in the amount of carbon dioxide in the atmosphere which will definitely contribute to the global warming.So it a man-made only and not the result of weather machine.
