Increasing concentrations of greenhouse gases are likely to accelerate the rate of climate change. Scientists expect that the average surface global temperatures could rise by 1-4.5°F (0.6-2.5°C) in the next fifty years. Evaporation will increase as the climate warms, which will increase average global precipitation. Scientists blame greenhouse effect for global warming. And consequently we, mankind, are blamed for greenhouse effect. Carbon dioxide, a cause of greenhouse effect, is so to say a side action of in man-made devices such as automobiles and power plants. But Robert Essenhigh, E.G. Bailey Professor of Energy Conservation in Ohio State's Department of Mechanical Engineering says that it is the rising global temperatures that are naturally increasing the levels of carbon dioxide, not the other way around.

We invent different things to facilitate our life but the effects play a bad role for our universe. But we know perfectly well that global climate change took place centuries ago when the mankind was not so developed and advanced as we now are. And our evolution has not stopped we are moving forward. During the last years scientists have been speaking about global warming. According to the National Academy of Sciences, the Earth's surface temperature has risen by about 1 degree Fahrenheit in the past century, with accelerated warming during the past two decades. There is new and stronger evidence that most of the warming over the last 50 years is attributable to human activities.
