Some aspects of climate change with emphasising on reducing greenhouse gas emissions

Abstract

In recent decades, changes in climate have caused impacts on human and natural systems, such as human diseases and environmental problems. The aim of the present paper is to give an overview, over the past decades and up-to-date in the climate change and its impacts as well as global warming in general, it serves as an introduction assessing atmospheric concentrations of greenhouse gases (GHGs) and gives general background reviews on the environmental policies of reducing GHG emissions at international levels for the climatic and environmental changes. Influences of human on the climate and environmental systems are clearly and recently man-made GHG emissions globally are the largest in history. So, the earth’s average temperature has been increasing since the industrial revolution
