Watch 27 Years of ‘Old’ Arctic Ice Melt Away in Seconds

Repost This

The total amount of Arctic sea ice is near record low for this time of year. The amount of ice isn’t the only big story, though. A video from the National Oceanic and Atmospheric Administration shows a disturbing trend in the age of Arctic ice.

Since 1988, Arctic sea ice is getting younger, and young ice is not a good thing. In 1988, ice that was at least 4 years old accounted 26 percent of the Arctic’s sea ice. By 2013, ice that age was only 7 percent of all Arctic sea ice.

Watch the 59-second video above and you can see the older ice do a vanishing act as it’s replaced by newer ice.

The vanishing act is occurring because climate change is helping warm the ocean waters in parts of the Arctic. Those warmer temperatures are whittling away at older sea ice during the summer melt season.

Replacing this thicker, harder old ice with young ice, which is generally thinner and melts more easily, is also contributing to the steep decline in summer sea ice extent and could trigger a feedback loop. That’s because less ice means more dark ocean water is exposed to the sun, which absorbs more of the incoming sunlight than white ice. That means warmer waters, which could in turn mean even less old ice and ice cover with each passing year.

I just ponder if you are missing something. I do understand that we are kind of hurting Our planet. But do we know how long this planet would stay fit without us living here?

What if it would be the same? And all that happens now is due to facts from the inside of Earth.

Thanks for letting me ponder.
