Extraction of Gigatons of Groundwater , May Be Responsible For Polar Shift.
According to a new study, humans extracted so
much groundwater between 1993 and 2010 that it
has contributed to the migration of Earth's poles.
ScienceAlert reports that the new analysis
was led by geophysicist Ki-Weon Seo
of Seoul National University.
The findings confirm previous estimates that
groundwater depletion caused by human activity
resulted in a polar shift of 80 centimeters toward the east.
The analysis was performed to reach a better
understanding of the polar motion phenomenon and
how changes in Earth's water distribution could impact it.
Earth's rotational pole
actually changes a lot. , Ki-Weon Seo, Geophysicist at Seoul
National University, via ScienceAlert.
Our study shows that among climate-related
causes, the redistribution of groundwater
actually has the largest impact on
the drift of the rotational pole, Ki-Weon Seo, Geophysicist at Seoul
National University, via ScienceAlert.
Humans pumped approximately 2,150 gigatons
of groundwater between 1993 and 2010, according
to 2010 estimates based on climate models.
Polar motion data are available
from as early as the late 19th century. , Ki-Weon Seo, Geophysicist at Seoul
National University, via ScienceAlert.
So, we can potentially use those
data to understand continental
water storage variations
during the last 100 years, Ki-Weon Seo, Geophysicist at Seoul
National University, via ScienceAlert.
Were there any hydrological
regime changes resulting
from the warming climate?
Polar motion could hold the answer, Ki-Weon Seo, Geophysicist at Seoul
