|Journal Impact Factor (JIF) can be a measure reflecting the average number of citations to articles released in journals, textbooks, patent document, thesis, task reports, news paperwork, conference/ seminar process, documents published throughout internet, notes and any other approved documents. It truly is measure the relative incredible importance of a journal inside of its field, with journals connected with higher journal influence factors deemed to become more important than include those with lower ones. 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.Accordingly, fluctuations over periods shorter than a few decades, such as El NiÃ±o, 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. In this sense, especially in the context of environmental policy, the term climate change has become synonymous with anthropogenic global warming. Within scientific journals, global warming refers to surface temperature increases while climate change includes global warming and everything else that increasing greenhouse gas levels will affect.
