Abstract
In the 19th century, the sensitivity of the Arctic to climate change was recognized because initial warming (or cooling) sets in motion a chain of events that amplify the warming or cooling and the phenomenon is known as the albedo feedback. Due to the rapid pace of Arctic warming in recent times, an unprecedented reduction in Arctic sea ice and permafrost are reported, which brings changes in Arctic weather. Arctic Life mainly depends on the biological productivity of the region, unique ecosystem, and seasonal presence of sea-ice. Rapid and judicious mitigation may help retard Arctic warming in the future. Sincere efforts be made and good practices be adopted to reduce the short-lived climate pollutants, such as black carbon, methane, tropospheric ozone, and hydrofluorocarbons, which may help reduce the rate of Arctic warming drastically. In this chapter, Climatic Change over Arctic and Effect of Arctic on Global Climate are discussed covering significant aspects of climate change consequences and impact.
