Climate change is a change in weather condition in long term. There is a huge difference between weather and climate change. Weather is the name of variation in temperature, wind, rainfall and humidity over the short period of time. These short term changes in atmosphere can be forecast with substantial skills and for a week in advance. Some changes in climate like droughts can be predicted with little knowledge and skills from season to season.
It is clear about the difference between weather and climate change but still there is a need to define climate change properly.
Definition of Climate Change
Climate change phenomena is the long term and unpredictable variations in rainfall pattern, rise in temperature, rise in sea level, melting of glaciers, floods and storms are also the part of climate change. One can say that on climate change is the changes in statistical properties of the global climate system that keep going for several decades.
Climate change is caused by many factors like variations in global temperature mainly caused by the concentration of greenhouse gases. Change in global temperature is the aspect of Climate change that is known as global warming. Climate change is something bigger than global warming. Climate change includes changes in rainfall, wind patterns, and temperature.
Is Climate Change Real
The artificial satellites around the earth and advance technologies make it possible for scientists to see the clear picture on broader level. They collect more information about earth and its climate and the pooled data of solid information collected over many years is showing changes in global climate. In Fifth Assessment Report of intergovernmental panel on climate change (IPCC) _2014, experts and scientists conclude that these changes in earth atmosphere are extremely likely to be a result of human activities. Changes seems in ice bodies of Antarctica, Greenland and other tropical mountains glaciers are the natural respond of earth climate to changes in greenhouse gases level. Since late 19 century, the rise in global average temperature about 1.62 oF (0.9 oC) is due to increase in carbon and other human made emissions in atmosphere.
