Climate change is the greatest ecological, economic, and social challenge of our time. Researches over many years show links between human activities and warming of the atmosphere and oceans. This warming has caused changes to the climate system, such as changes in rain and wind patterns, reductions in the size of Himalayan Glaciers and demolished many ecosystems. Impact of climate change on earth ecosystems refers to effects of various climatic conditions on major ecosystems of earth while emitting greenhouse gases in the atmosphere, increasing temperature etc. This book reflects understanding of researchers, representing the current situation national and international level on various impacts of climate change on earth ecosystems.
