Climate is a global process; it is emerged as the most significant global environmental issue. It has engaged the attention of scientists, planners, government and politicians alike worldwide. It is not only a threat and but also a challenge. Climate changes and climate fluctuations particularly changes in weather contrary, affect the environment that give us cleaned food, air, water, shelter and safeguard us. Climate change found that rising temperatures to about 5 ⁰C to the normal as a result enlarge the frequency or intensity of some contrary weather occurs, a rising sea levels, and unfreezing snow and ice. Global warming on account of buildup of greenhouse gases especially carbon dioxide in the atmosphere is a significant threat to biodiversity. As a result of increasing temperatures the endemic species such as emperor penguins, seals, ringed seals, walruses etc are threatening. Climate convert is already forcing the life forms to alter either through shifting of natural environment, changing of life cycle or the development of new visible characteristic features. These primarily analysis discuss the significance of biodiversity, the consequences faced by the plant, animals, human beings and ecosystem. Environmental conditions are constantly changing. The Earth’s diurnal rotation and the annual rotation of the Earth around the Sun drive changes in temperature and radiation and these coupled with the centrifugal motion of the planet and convection currents cause climatic changes on timescales from seconds to years. Conditions may also be altered by the impact of other organisms. For example, in the absence of oxygen, heterotrophic bacteria will reduce the pH of soil (i.e. increase its acidity).
