Climate change is the long-term ongoing shift in temperatures and weather patterns on Earth, due to human activities. The combustion of fossil fuels including gas, coal and oil emits greenhouse gases such as carbon dioxide. Greenhouse gases trap heat on Earth and do not allow it to escape, causing the greenhouse effect. Furthermore, increasing temperatures continue to melt ice sheets, which contribute in rising sea levels. This further endangers coastal and island communities, whose livelihoods are jeopardized due to increased storms, which is another result of climate change. Rising temperatures cause more water to evaporate and precipitate resulting in severe flooding. This book explores all the important aspects of climate change in the present day scenario. It is appropriate for students seeking detailed information in this area as well as for experts.
