Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and its projected continuation. The Intergovernmental Panel on Climate Change (IPCC) concludes that most of the observed temperature increase since the middle of the 20th century was very likely caused by increasing concentrations of greenhouse gases resulting from human activity such as fossil fuel burning and deforestation. This book presents current research in the study of global warming, including climate change and its impact on agriculture; global warming and coral reefs; and climatic change due to clusterisation of atmospheric water vapor.
