The Recent study of NASA shows that, human activity place a very big role in global warming.The greenhouse gases generated by human beings is the main reason for global warming.The study about global warming from 2005 to 2010 by NASA conclude that the heat absorbed by earth is more than the energy returned to space.So the final concern of the study is, global warming increases year by year.
The amount of heat produced by the sun, that reaches the top of earth decrease by ten percentage because of shifts in sun's magnetic field. The Earth's energy imbalance has a direct effect of climate change.If the energy imbalance is positive then the earth becomes hot.If the energy imbalance is negative then the earth becomes cool.
The research on earth's energy imbalance by Hansen's team comes to a concern, that earth has absorbed more energy than it omitted,So that the earth's energy imbalance going to positive.Based on the research the earth will be hotter in future as well as the sun is not the cause for global warming.
