Thawing permafrost and global warming

Due to global warming, permafrost is melting faster. Permafrost is a soil or rock mass that remains frozen (below 0?C/32?F). Permafrost is found in the cold climates where the mean annual temperature remain below the freezing point. Such climate prevails near the North and South poles. In recent years the Arctic ice is melting faster which is causing thawing of permafrost in that region. When permafrost melts, it releases methane that accelerates global warming. Adverse effects of climate change are a reality and drastic measures need to be taken to reduce greenhouse gasses. Search for fossil fuel in the Arctic region should be stopped because drilling for oil may cause rapid collapse of permafrost soil. Use of fossil fuel has to be reduced and search for exploring clean and green energy sources has to be intensified through strengthening global cooperation and partnership.
