Shifting Earth axis
Global warming is now affecting the way earth wobbles on its polar axis. A new NASA study, which has focused on Greenland’s melting ice sheet and Antarctica’s ice sheet and changes in global hydrology, has found that earth’s axis is shifting at a slow pace. According to a study published on Friday in the journal Science Advances, melting ice sheets, especially in Greenland, are changing the distribution of weight on Earth. And that has caused both the North Pole and the wobble, which is called polar motion, to change course. Scientists and navigators have been accurately measuring the true...
