Climate Change

Climate change Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions or the distribution of events around that average (e.g., more or fewer extreme weather events). Climate change may be limited to a specific region or may occur across the whole Earth, such as global warming. Terminology The most general definition of climate change is a change in the statistical properties of the climate system when considered over long periods of time, regardless of cause.[1][2] Accordingly, fluctuations over periods shorter than a few decades, such as El Niño, do not represent climate change. The term sometimes is used to refer specifically to climate change caused by human activity, as opposed to changes in climate that may have resulted as part of Earth 's natural processes.[3] In this latter sense, used especially in the context of environmental policy, the term climate change today is synonymous with anthropogenic global warming. Within scientific journals, however, global warming refers to surface temperature increases, while climate change includes global warming and everything else that increasing greenhouse gas amounts will affect. Climate Change is the emission of greenhouse gases like C02 and methane is the result of industrialization other improper practices, which result into their production. The ozone layer which protects life on earth from ultraviolet (UV) radiations is becoming thinner gradually due to these greenhouse gases. The greenhouse gas emissions adversely affect our environment and are the underlying cause of the global warming phenomenon. There is a gradual shift in the patterns of climate observed over many years; it is therefore one of the global environmental issues. Understanding the different causes and factors associated with climate change is therefore important.
