What is the News?<\/b><\/h2>\n

A study published in the journal Geophysical Research Letters reveals that extensive groundwater extraction by humans has resulted in the earth\u2019s axis tilting nearly 80 cm to the east.<\/span><\/p>\n

How groundwater extraction influences Earth\u2019s rotation?<\/b><\/h2>\n

Earth\u2019s geographic north and south poles are where its axis intersects the surface. But these poles are not fixed.\u00a0<\/span><\/p>\n

The axis and hence the poles fluctuate due to variations in the Earth\u2019s mass distribution.<\/span><\/p>\n

In the past, the poles drift was only caused by natural forces like ocean currents and the convection of heated rock deep beneath the Earth.\u00a0<\/span><\/p>\n

But the research in 2016 showed how the movement of water around the world <\/span>influences the Earth’s rotation.<\/span><\/p>\n

Like adding a tiny bit of weight to a spinning top, the Earth spins a little differently as water is moved around.<\/span><\/p>\n

What did the researchers now find out?<\/b><\/h2>\n

Between 1993 and 2010, the excessive pumping of groundwater caused the planet\u2019s rotational pole to shift eastward by approximately 80 centimetres.\u00a0<\/span><\/p>\n

They also found that pumping groundwater from mid-latitude areas would impact the drift the most. The most amount of groundwater redistribution took place in northwest India and western <\/span>North America both situated at mid-latitudes.\u00a0<\/span><\/p>\n

About Groundwater Depletion in India<\/b><\/h2>\n

Groundwater depletion has been a particular concern across India since the last decade. About 95% of India\u2019s groundwater depletion was traced to north India where groundwater is primarily used for irrigation.\u00a0<\/span><\/p>\n

Punjab, Haryana, Delhi, and western Uttar Pradesh have critical groundwater levels due to the indiscriminate use of groundwater, while Rajasthan and Gujarat have low groundwater levels due to the arid climate.\u00a0<\/span><\/p>\n

Groundwater availability is also low in parts of Karnataka, Tamil Nadu, Telangana, and Andhra Pradesh due to the crystalline nature of the aquifers found here.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
