\"melting<\/a><\/p>\n

Morgaan Sinclair, Ph.D.<\/small>:
\nEarth has lost 12 trillion tons of ice in Antarctica and Greenland in less than 50 years.<\/a><\/h2>\n

Sea levels rose an inch. Every inch of sea level rise means 2-3 million more people get flooded at least once a year. Climate change since 2010 has accelerated the problem.<\/em><\/p>\n

… Global warming causes intensified hurricanes, warped El Ninos (we\u2019re having one right now), heat domes, melting ice and a subsequent loss of albedo (serious), and the collapse of ocean currents with the loss of salinity in the oceans because trillions of tons of water from melting glaciers diluted it. And it\u2019s the loss of albedo that portends things much worse.<\/p>\n

Definition: Albedo<\/strong><\/p>\n

Albedo is a measure of the percentage of sunlight that a surface reflects<\/em>. Ice, being white, reflects a greater percentage of sunlight back out into space. Conversely, our dark blue ocean absorbs much of the light, which is turned into thermal energy that heats the oceans. A loss of albedo when an ice cap\u2014say, the Arctic ice cap\u2014melts, means that there is more dark blue water. The more ice that melts, the warmer the ocean, and the faster more<\/em> ice melts. This can lead to exponential melting<\/em> that can destroy even very large ice sheets. In the past, the West Antarctic Ice Sheet (WAIS) experienced exponential melting, and when it did, it completely dissolved in fewer than 10 years, adding 2.0 million to 2.9 million cubic kilometers<\/strong> of pure liquid freshwater into the ocean. This raised sea levels globally 5.8 to 8.0 meters\u201418 to 26 feet.<\/em><\/strong><\/p><\/blockquote>\n<\/blockquote>\n
