The Changing Climate

Paresh V Modh

Abstract :

 The term greenhouse effect refers oadly to the partial trapping by the atmosphere of radiation from the  Earth’s surface, leading to a surface temperature that is larger than would be the case without the atmosphere.  Greenhouse gases such as carbon dioxide (CO2) absorb heat (infrared radiation) emitted from earth’s surface.Some scientists are concerned that the heat in the Earth‘s atmosphere may be increasing to dangerous levels due to the greenhouse effect. Human activities  especially the burning of fossil fuels since the start of the Industrial Revolution have increased atmospheric CO2 concentrations by  about 40%, with more than half the increase occurring since 1971. Since 1905, the global average surface temperature has increased by  about 0.8°C. This has been accompanied by warming of the ocean, a rise in sea level, a strong decline in Arctic sea ice, and many other  associated climate effects. Much of this warming has occurred in the last four decades. Detailed analyses have shown that the warming  during this period is mainly a result of the increased concentrations of CO2 and other greenhouse gases. Continued emissions of these  gases will cause further climate change, including substantial increases in global average surface temperature and important changes in  regional climate. The magnitude and timing of these changes will depend on many factors, and slowdowns and accelerations in warming lasting a decade or more will continue to occur.
