Between 1972 and 2016, 27 separate leap seconds were added as Earth slowed. But the rate of slowing was tapering off. "In 2016 or 2017 or maybe 2018, the slowdown rate had slowed down to the point that the Earth was actually speeding up," Levine said....
But to keep time marching on, a long-term slowdown of Earth’s spin decades ago led to the introduction of the leap second in 1972. Since then, 27 leap seconds have been added to keep the Coordinated Universal Time updated. But if Earth’s rotation really is speeding up, not only does...
(B)Water pollution is speeding up around the world. We use over 75,000water-polluting chemicals and make about 1,000 new ones each year. When it rains, water runs over the ground and carries oil, dirt and other harmful stuff to the rivers and lakes. So, anything harmful that we use ...

Earth’s distance from the sun is constantly changing. speeding up and slowing down. A predictable asymmetrical pattern throughout the year. This elliptical orbit is described by Kepler’s three laws of planetary motion. Keplar’s Law II describes how planets in orbit carve out equal arcs in...
Cranking up its three science instruments, the spacecraft on Sunday will observe the harmless asteroid known as Donaldjohanson. The encounter will take place 139 million miles (223 million kilometers) from Earth in the main asteroid belt between Mars and Jupiter, so far away it will take 12 ...
sea levels have risen faster than in any preceding century in at least the past 3,000 years, and this is set to continue for a very long time. the process is also speeding up. over the past 140 years, sea levels have risen worldwide by 21 to 24 centimeters. but roughly 10 centimeter...
