Arctic is heating twice as fast as the global average, the volume of arctic sea ice by September 2019 after the melting season has declined by 50% compared to the average between 1980 to 2019. Less and less of arctic sea ice and warming ocean water leads to extreme summer and winter events in the Europe and Asia, and it is also one the most visible danger signs of extreme climate changes all over the world.When more ice melts more ocean surface is exposed to absorb heat from sun warming the ocean water more and the region. It is predicted that arctics ice cover will disappear by 2025, but some scientists predict it will disappear between 20 years to 50 years from now.
