Keeping communities’ safe starts by having a strong plan in place that leverages some of the best, but underutilized tools we have to protect or communities: nature. Paired with the 2019 Arctic heatwave, this melting rate may produce disastrous outcomes. Global warming has caused the shrinking and reduction of the ice caps covering the North and South poles on the planet. Every summer, warmer air temperatures cause melt over about half of the surface of the ice sheet — although recently, 2012 saw an extreme event where 97 percent of the ice sheet experienced melt at its top layer. Arctic ice is decreasing by 9 percent each decade, according to data derived from NASA satellite images. [More] Some scientists believe this shift in ocean currents could come surprisingly soon--within as little as 20 years, according to Robert Gagosian, president and director of the Woods Hole Oceanographic Institution. Ice acts like a protective cover over the Earth and our oceans. Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons. We do not come in contact with icebergs or ice sheets very often. The melting of Arctic ice caps is likely to increase traffic in and the commercial viability of the Northern Sea Route. This instability will continue to mean higher prices for you and growing crises for the world’s most vulnerable. Polar vortexes, increased heat waves, and unpredictability of weather caused by ice loss are already causing significant damage to crops on which global food systems depend. If emissions continue to rise, the current rate of melting on the Greenland ice sheet is expected to double by the end of the century. The polar regions are particularly vulnerable to a warming atmosphere. According to scientists at the U.S Center for Atmospheric Research, if the current rate of global temperature rise continues, the Arctic will be free of Ice … As this ice melts, darker patches of ocean start to emerge, eliminating the effect that previously cooled the poles, creating warmer air temperatures and in turn disrupting normal patterns of ocean circulation. Although they were abnormally large, the state of the polar ice caps in 1979 became the standard baseline in NASA’s study. Icebergs are chunks of glacial ice that break off glaciers and fall into the ocean. In theory, the Arctic remains colder than the equator because more of the heat from the sun is reflected off the ice, back into space. If Arctic ice melt doesn't boost sea levels, do we care? The new study, published in Nature Communications, found that the cause of this gain in freshwater concentration is the loss of sea ice in summer and autumn. How do melting sea ice and glaciers affect weather patterns? Antarctic ice levels may be at a new maximum, but we are still losing ice from the Arctic polar ice caps melting at an astounding rate. Raised sea levels may submerge some part of many cities and lands on the sea shore. In essence, the melting of the polar ice caps will accelerate global warming, which will, in turn, cause more rapid melting. Glaciers around the world can range from ice that is several hundred to several thousand years old and provide a scientific record of how climate has changed over time. Scientists project that if emissions continue to rise unchecked, the Arctic could be ice free in the summer as soon as the year 2040 as ocean and air temperatures continue to rise rapidly.
