Melting Ice in the Arctic Sea National Polar and Ocean Research Center (NCPOR) has found a dramatic decrease in Arctic sea ice due to global warming. Due to the decrease in sea ice, there has been an increase in evaporation, air humidity, cloud cover and rainfall locally. Arctic sea ice is a sensitive indicator of climate change and has strong countervailing effects on other components of the climate system. NCPOR has noted that the largest decline in Arctic sea ice in the last 41 years occurred in July 2019. Over the last 40 years (1979–2018), sea ice has been declining at a rate of -4.7 percent per decade, while its rate of decline was found to be -13 percent in July 2019. If this trend continues, there will be no ice left in the Arctic sea by 2050, which will prove to be dangerous for humanity and the entire environment. The study also revealed that the decline in Arctic sea ice and an increase in the summer and autumn seasons have affected the local weather and climate over the A
