“Greenhouse gas emissions contribute to global warming, which is reducing the amount of summer sea ice in the Arctic. Polar bears use sea ice for feeding, mating and giving birth.” (Thiessen. 2015). This is a truth about global warming’s impact on our lovely polar bears. They are losing their home because of the increasing temperature. Global warming is a big issue on our earth. Global warming is due to a large amount of human use of coal, oil and other fossil fuels, resulting in greenhouse gas (mainly CH4, freon, nitrogen, CO2, etc.) emissions which cause the temperature of the Earth 's atmosphere and oceans to rise excessively. Carbon dioxide is a part of the problem of Global warming. Deforestation or people burning fossil fuels such as oil, coal, etc., produce large amounts of carbon dioxide and other greenhouse gases. “Visible radiation from the sun is highly permeable, and emitted from the Earth longwave radiation is highly absorbent and can strongly absorb infrared terrestrial radiation, causing the Earth 's temperature rises, the greenhouse effect. “ (Wikipedia, 2015). When the greenhouse effect continues to accumulate, it leads the gas system to absorb and emit the energy imbalance into the air system, resulting in temperature rise, causing the global warming phenomenon. Global warming will push the global redistribution of precipitation, melting glaciers and permafrost and raising sea levels. This is not only detrimental to the balance of natural ecosystems, but…
