The shifting climate affects ecosystems and society in a wide variety of ways. Extreme weather events have become frequent and vivid, for example, heat waves, and rainfall patterns are changing. Weisse and Storch (2009)…

(2007) describes climate change as the statistically substantial variation in the mean condition of climate (p.145). Climate change has also been described by Maunder (1992, p. 34) as a change in climate ascribed directly or indirectly to human activity that changes the global atmospheric composition observed over a period.
Ocean variability, solar radiation variations, plate tectonics, volcanic explosions, human activities and orbital variations cause climate change. Oceans are vital and critical elements of the climate system (Christopherson, 1992, p.223). Short-term changes in oceanic oscillations cause climate variations. Modification to ocean processes plays a significant role in spreading heat through slow and deep water movement. Differences in earth’s orbit positions cause seasonal changes in sunlight distribution (Christopherson, 1992, p.222). There are three types of orbital variations i.e. earth’s eccentricity variation, variation of the tilt angle of earth’s axis of rotation and the earth’s axis precession. Climate change causes variations in sun radiation. It has triggered little ice age, and temperature increase observed in 1900’s to 1950’s. Volcanism is a significant factor that triggers climate change. Wignall (2001) asserts that volcanic eruptions emit carbon dioxide causing immense effects on the climate (p. 21). Forest et al. (1999) assert that plate tectonics affects local and global patterns of climate and atmosphere-ocean circulation (p. 23). Solomon et al. (2009, p. 1705) asserts that human activities leading to increased carbon dioxide emission are the key factors contributing to climate change. Effects and Events of Climate change
Climate change still remains to be a global hazard since the green house gases continue to increase across the world (McCathy, 2001, p. 124). Climate change has adverse effects on the environment, ecological systems and the social systems (Cline, 2007, p. 145). Climate change increases or

The climate change is the term that is used to refer the Global warming due to the emission of the green house gases. The major reason of the climate change is the emissions of green house gases. The issue is now realized and many governments and industries try to opt more sustainable ways instead of utilizing the conventional methods to generate energy.
Peoples evidently observed the melting of the glaciers in the North Pole, the increase of sea level in tropical zones at an average rate of 1.8 [1.3 to 2.3]mm/yr since 1993 and the warming of the earth which affects the cycle of vegetation and farm life (Intergovernmental Panel on Climate Change, 2008).
Essay on Climate Change Debate Introduction: The climate change around the world is seen as a combination of several factors, which act in an interrelated fashion. Observation and research conducted suggests out of several factors three most essential factors like alterations in the rate of solar radiations on the earth’s atmosphere, alterations in the atmospheric constituents and other such alterations on the earth’s topography earn responsibility for the changes in climate.
Climate change can be due to: Natural variability – warming or cooling due to sun spot activity, solar radiation Human activity – burning of fossil gases into the atmosphere, causing enhanced greenhouse effect However, there is much debate about what causes climate change, and the UN Framework Convention on Climate Change refers to a change of climate that is attributed directly or indirectly to human activity that alters the global atmosphere.
According to the paper, the effects of climate change are increasingly felt in many parts around the world. Human life and activities are affected by weather and climate, and changes in climate affect man and animals, food production, water sources and health. Short-term changes in climate can be classified as normal weather conditions.
Name Instructor Class Date Global Climate Change Although the subject was not part of the recent presidential debates, global climate change is the most important issue facing the U.S. and the world. Also refereed to as “global warming” the phenomenon is already taking its toll on the planet.
The climate system evolves in time under the influence of its own internal dynamics and due to changes in external factors that affect climate (called 'forcings'). External forcing includes natural phenomena such as volcanic eruptions and solar variations, as well as human-induced changes in atmospheric composition.
(The greenhouse gases of the majority concern are Carbon Dioxide (CO2), Methane (CH4), with nitrous oxides.) The recent consequence that climate modify has had is the equal of a 1 watt light bulb burning over each square meter of the earth (Brown BE, 163-170).
It focuses on terms and concepts of ocean logy. It further focuses on the study related to Ocean and atmospheric interaction. It makes use of two of the figures to carry out a healthy analysis of the terms and
