Acknowledgement
We would like to thank Dr M.G. Prasuna, Head- Languages Group, BITS-Pilani Hyderabad Campus for giving us an opportunity of preparing a group report on ‘The Effects of Global Warming’ as an evaluation component for the course Technical Report Writing (TA C312). It would not have been possible to prepare it within the stipulated time without her unwavering guidance and support.

1. Introduction
Look closely and you will see the effects of climate change.
Scientists have documented climate induced changes in some 100 physical and 450 biological processes. In the Russian Arctic, higher temperatures are melting the permafrost, causing the foundations of five story apartment buildings to slump. Worldwide, the rain, when it falls, is often more intense. Floods and storms are more severe and heat waves are becoming more extreme. Rivers freeze later in the winter and melt earlier. Trees flower earlier in spring, insects emerge faster and birds lay eggs sooner. Glaciers are melting. The global mean sea level is rising.
Even if we reduce our greenhouse gas emissions dramatically today, these trends will continue for decades or centuries to come.
The rate of climate change expected over the next 100 years is unprecedented in human history. Throughout geologic time the average global temperature has usually varied by 5° Celsius over intervals of millions of years. Now scientists believe that the temperature of the Earth’s surface – which has already risen by 0.6°C since the late1800s – is likely to increase by another 1.4 to 5.8°Cduring the course of the 21st century.
Such an unusually rapid rate of change would affect fundamental Earth systems upon which our very lives depend – including ocean circulation and the hydrological, carbon and
