Effect of Global Warming on Mankind - A Review

The concentration of several greenhouse gases has increased over time. Human activity increases the greenhouse gases effect primarily through release of carbon dioxide, but human influences on other greenhouse gases is also important. The ongoing accumulation of greenhouse gases causes increasing global warming. The recent IPCC (Intergovernmental Panel on Climate Change) 2007 shows that global average air temperature near Earth’s surface rose 0.74±0.18°C in the last century and report concluded “most of the observed increase in globally averaged temperatures since mid – 20 th century is very likely due to the observed increase in the concentration of anthropogenic greenhouse gases. Global warming affects many different facets of life on Earth. Global warming effects will include changes in agricultural yields, the continued melting of glaciers and species extinctions. New items were gradually added to the list, ranging from the degradation of ecosystems to threats to human health. Experts in fields from forestry to economics, even national security experts, pitched in to assess the range of possible consequences. The unfortunate reality is that predicting the impact of global warming is notoriously hard. It brings a whole range of scientific disciplines together, such as oceanography, meteorology, and geology, while no one can agree on the exact impacts for specific regions of the world. All scientists agree global warming will have numerous negative effects on our planet and our way of life. The effect of global warming will have adverse effect on the climatic conditions and water resources.
