The Earth has tilted 31.5 inches because of human activity   https://www.indy100.com/science-tech/earth-tilted-315-inches-sea-level global balance   When humans pump groundwater, it has a substantial impact on the tilt of Earth’s rotation.   Additionally, a study documents just how much of an influence groundwater pumping has on climate change.   Understanding this relatively recent data may provide a better understanding of how to help stave off sea-level rise.   Water has power. So much power, in fact, that pumping Earth’s groundwater can change the planet’s tilt and rotation. It can also impact sea-level rise and other consequences of climate change.   Pumping groundwater appears to have a greater consequence than ever previously thought. But now — thanks to a study published in the journal Geophysical Research Letters — we can see that, in less than two decades, Earth has tilted 31.5 inches as a result of pumping groundwater. This equates to...

   The land beneath the New York City area, including the borough of Queens, pictured here, is moving by fractions of inches each year. The motions are a legacy of the ice age and also due to human land usage. NASA/JPL-Caltech Scientists using space-based radar found that land in New York City is sinking at varying rates from human and natural factors. A few spots are rising.   Parts of the New York City metropolitan area are sinking and rising at different rates due to factors ranging from land-use practices to long-lost glaciers, scientists have found. While the elevation changes seem small – fractions of inches per year – they can enhance or diminish local flood risk linked to sea level rise.   The new study was published Wednesday in Science Advances by a team of researchers from NASA’s Jet Propulsion Laboratory in Southern California and Rutgers University in New Jersey. The team analyzed upward and downward vertical land motion – also known as uplift an...
