April is sea-ice melt month in traditionally ice-covered Arctic waters and regions in the north. Since satellite measurements began in 1979, this past April was recorded as the second-lowest level. Data shows that multi-year thicker ice also is declining. Second and third-year ice declined by 30% and 10% respectively. Data was compiled by the National Snow and Ice Data Center in Boulder, CO.
Sea-ice coverage has become the harbinger of the global warming issue and often portrayed as evidence that the situation in the Arctic is foreshadowing the coming serious repercussions of carbon emissions and human-caused pollution. The polar bear population in the Hudson Bay region will see direct affects from continued sea-ice melting and earlier thawing. Conservation groups such as World Wildlife Fund and Polar Bears International are working tirelessly to create awareness and action movements to recognize and implement ways to curb carbon emissions and control global warming.
