‘’For the first time ever, we have presented a plausible physical mechanism that
explains the enigmatic decadal oscillation of the pole. It is decadal scale variability
in (global) land water storage pattern that drive the decadal polar motion’’, he said.
The newly discovered line between polar motion and global scale terrestrial water
storage variability has broad implications for the study of the past and future climate
according to the paper.
‘’The main point is that we have established a connection in global and delicate motion
of Earth’s spin axis, Adhikari said. " In a way such motion of pole is sort of barometer
of climate change- just like melting of glacier or rising sea level or rising melting
temperature.’’
"So, we recommend that the polar motion data be utilized to constrain the model of past
climate change which will have important ramifications for future climate change."

Coronavirus Disease 2019(COVID - 19)
The 2019–20 coronavirus outbreak is an ongoing public health emergency of
international concern involving coronavirus disease 2019. It is also called COVID-19.
It is first identified in Wuhan,
Hubei Province, China. Till 12
March 2020, more than 4,729
are died by this virus and more
than 110 countries' people are
affected.
Human first get a coronavirus
from contact with animals.
The virus primarily spreads
between people in a similar way
to influenza, via respiratory
droplets produced during
coughing or sneezing. The
time between exposure and Coronavirus Disease symptoms
symptom onset is typically
five days, but may range from two to fourteen days. Symptoms may include fever,
cough, and shortness of breath. Complications may include pneumonia and acute
respiratory distress syndrome. There is currently no vaccine or specific antiviral
treatment. Recommended preventive measures include hand washing, maintaining
distance from people who are sick, avoiding close contact with people suffering from
acute respiratory infections, avoiding unprotected contact with farm or wild animals,
and monitoring and self-isolation for fourteen days if an individual suspects they are
infected.
China and other many countries of world have included travel restrictions, quarantines,
and curfews. The world's economic instability is occuring because of coronavirus.
