Global Warming May Change How Earth Spins

A new study done by NASA states global warming may be changing how the Earth spins.

Sources say that researchers used NASA’s two Gravity Recovery and Climate Experiment (GRACE) satellites to figure out the axis on which the Earth revolves shifted toward the east.

They linked this shift to an alteration of the distribution of mass on Earth due to melting ice sheets, particularly in Greenland.

Greenland is said to be losing approximately more than 287 billion tons of ice each year, and Antarctica is at present losing 134 billion tons of ice annually.

The losses in mass apparently triggered the Earth’s shake, or polar movement, to slightly alter.

The shift in polar motion implies the areas of the North and South Poles changed also.

An earlier study has shown over the past 115 years, the North Pole moved roughly seven to eight centimeters each year toward Canada.

However, the NASA research says the North Pole started moving in the year 2000 toward Europe and the UK.

The research didn’t attribute a definite cause to the shift in the distribution of mass; however, it seems environment change factors are at least partly accountable.

Adhikari approximated the melting ice sheets in Greenland have brought about forty percent of the change in polar motion in comparison to twenty-five percent brought on by Antarctica.

Another twenty-five percent, Adhikari stated, is because of shifts in continental water storage, although it isn’t clear what brought about these particular changes.

Likely reasons are increasingly more droughts that may be a result of global warming, or a rise in humanity’s removal of water from the Earth.

While the research failed to name any possible results of the Earth’s new rotation, it does show the enormous affects people and climate change may have on the physical stability of the planet.

NASA’s announcement comes some weeks after a pair of researchers came to the conclusion that melting ice sheets may cause sea levels to surge several feet towards the end of the century.

As stated by those researchers, if humanity fails to stop its emissions of greenhouse gases, several of the most populous cities in the world might be at risk of drowning.
