Global warming is the climatic change phenomenon by which atoms of certain gaseous molecules are held together in the earth鈥檚 atmosphere to trap heat and releases radiation, which heats the earth.

The several causes associated with global warming are industrialization, oil drilling, deforestation, power plants, increasing livestock farming, fertilizers, ocean warming pattern, rising tropopause, natural calamities, andgreenhouse effect.

Some preventions of global warming are reducing fossil fuel and waste, planting trees, reducing CO2 (carbon dioxide) emission, fuel cell buses, and reducing deforestation.

The term 鈥渋ce sheet鈥� represents the covering of glacial ice, mainly in Greenland and Antarctica, which contains an enormous amount of frozen water.

Various characteristics related to ice sheets are dome-shaped, slow movement downhill, and behaving like a liquid. Some causes of ice melting are greenhouse gas emissions, gas drilling, deforestation, and global warming.

Climate change is rapidly occurring. Areas with frozen ice reflect sunlight to cool the planet. The planet is becoming hotter due to more sunlight absorption by water or dark-colored ground.

This causes a positive feedback loop and this results in more melting ice due to warming of the environment and greenhouse gases emissions of the Arctic permafrost.
