Studies Show Global Warming Could Change the Length of the Day

May 04, 2007
Will global warming make the day shorter or longer?
Unless you've been living under a rock for the past five years, then you've likely already read countless articles and heard many reports about the current global warming crisis our world faces. The concept of global warming has faced lots of criticism and outright denial, but at this point in time, most of the world's leading scientists are in agreement that global warming is real and is having a profound effect on the future of the environment.In the face of recent events and cold hard facts, many who once disbelieved the idea of global warming have come to change their minds, noting that the earth's climate is definitely changing, with the most recent changes happening just this past year. Strange weather patterns, rising tides, melting ice shelfs and other occurrences all lend credence to those who say the environment is in trouble and that global warming is the culprit.Now, it would seem that another change looms on the horizon. A new study conducted by Jochem Marotzke, a scientist conducting research at the Max Planck Institute in Germany, shows that global warming could cause the day to grow shorter.Jochem Marotzke explains that as a result of global warming, sometime over the next century or two, warming ocean waters will cause the ocean's circulation to change, along with sea levels. These changes will cause the ocean's water to be redistributed toward the North Pole, causing the Earth to spin faster on its axis.
Other research contradicts Jochem Marotzke initial findings on the effects of global warming, showing that a warmer atmosphere would serve to create stronger winds, in effect causing the earth to slow its rotation, and thus making the day longer.
