The Earth is warming and progressively melting Sea Ice worldwide.
Earth’s Northern Polar Ice Cap has been progressively melting over the past 40 years with about 3 million km2 lost so far.
Melted Sea Ice blends into the ocean Sea water, and this progressively raises the Global Sea Level.
In total, Arctic/Greenland ice could add 10 metres to Global Sea Level.
