Climate Change means the difference in the Earth's global climate or in regional climates over time. Climate Change is now a major global concern .Climate change melts the ice. It describes changes in the state of the atmosphere over time scales ranging from decades to millions of years. These changes can be caused by processes inside the Earth, forces from outside (e.g. variations in sunlight intensity) or, more recently, human activities. Ice ages are prominent examples. Climate change is any significant long-term change in the expected patterns of average weather of a region (or the whole Earth) over a significant period of time. Climate change is about abnormal variations to the climate, and the effects of these variations on other parts of the Earth. Examples include the melting of ice caps at the South Pole and North Pole. These changes may take tens, hundreds or perhaps millions of years.
