Climate change and the Moon are teaming up to create record floods on Earth | Salon.com

The Moon’s orbit is “wobbling” — and that plus climate change will wreak havoc on the ground

At the time of this writing, at least 120 people have been confirmed dead because of severe flooding in Western Europe.

It is tragically likely that, when this story is over, the number will be significantly higher. A German weather service (DWD) spokesman told CNN that in some areas there has not been this much rainfall in 100 years.

These extreme weather events are inextricably linked to climate change, politicians and experts have noted.

But there is another culprit, one above, that is also affecting the weather: a “wobble” in the orbit of the Moon. Indeed, only days before the flooding, a study in the journal Nature Climate Change by scientists from NASA and the University of Hawaii warned that the Earth may experience record flooding in the mid-2030s because of changes in the Moon’s orbit.

For the past 15 years, billions of people have turned to Google Earth to explore our planet from endless vantage points. You might have peeked at Mount Everest or flown through your hometown. Since launching Google Earth, we’ve focused on creating a 3D replica of the world that reflects our planet in magnificent detail with features that both entertain and empower everyone to create positive change.

In the biggest update to Google Earth since 2017, you can now see our planet in an entirely new dimension — time.

With Timelapse in Google Earth, 24 million satellite photos from the past 37 years have been compiled into an interactive 4D experience. Now anyone can watch time unfold and witness nearly four decades of planetary change.

Climate Change Has Knocked Earth Off Its Axis

Of all the things attributable to climate change, the rotational poles moving differently is definitely one of the weirder ones. But a new study shows that’s exactly what’s happening. It builds on previous findings to show that disappearing ice is playing a major role, and shows that groundwater depletion is responsible for contributing to wobbles as well.

The findings, published last month in Geophysical Research Letters, uses satellites that track gravity to track what researchers call “polar drift.” While we think of gravity as a constant, it’s actually a moving target based on the shape of the planet. While earthquakes and other geophysical activities can certainly play a role by pushing land around, it’s water that is responsible for the biggest shifts. The satellites used for the study, known as GRACE and GRACE-FO, were calibrated to measure Earth’s shifting mass

Scientists: Human activity has pushed Earth beyond four of nine ‘planetary boundaries’ – The Washington Post

conclusion of a new paper published Thursday in the journal Science by 18 researchers trying to gauge the breaking points in the natural world.

The paper contends that we have already crossed four “planetary boundaries.” They are the extinction rate; deforestation; the level of carbon dioxide in the atmosphere; and the flow of nitrogen and phosphorous (used on land as fertilizer) into the ocean.
