New photo Earth is WOBBLING worse than ever and humans are partly to blame, NASA reveals

EARTH is ‘wobbling’ partly because of human impact on the planet – causing it to shift more than ten metres in the last century, scientists say.

Experts at NASA’s Jet Propulsion Laboratory in California have tracked changed over the entire 20^th century to explore what is scientifically known as “polar motion”.

The Earth is WOBBLING and has moved ten metres, according to scientists at NASA

The Earth is not like the globes you may find sitting on a desk. It is not a perfect sphere and doesn’t rotate smoothly while it spins – instead it drifts and wobbles.

NASA have broken down the three main reasons for this, the first being ‘glacial rebound’.

This happens when glaciers cover a larger area that causes the planet to be squeezed and bulge at the end of the ice.

As they melt the bulging changes shape and redistributes the Earth’s mass. Although this last happened 26,000 years ago the planet is still slowly changing shape.

Huge glaciers covering large areas of the planet were responsible for ‘squeezing’ the Earth like a stress ball

The second reason is what scientists call ‘mantle convection’.

This theory is similar to the ice one that says the shifting is due to large rocks in the Earth’s core moving over each other and making the planet wobble.

The third and final one is human influence. NASA says this is that of a rapidly warming environment thanks to climate change.

Greenland’s ice caps melting saw 7,500 gigatons of ice drift into the ocean. This weight change could have contributed to the wobble.

Eric Ivins of JPL said: “There is a geometrical effect that if you have a mass that is 45 degrees from the North Pole – which Greenland is – or the South Pole (like Patagonian glaciers), it will have a bigger impact on shifting Earth’s spin axis than a mass that is right near the pole.”

HOW THE EARTH IS 'WOBBLING'

The science behind NASA’s discovery might be slightly confusing, but not when broken down in simple stages.

NASA think there are three contributing reasons behind the Earth wobbling. They are as follows…

1. Glacial rebound – when giant glaciers cover a huge area, the planet bulges like a tennis ball slightly squeezed. As it melts it changes shape and redistributes Earth’s mass. This last happened 26,000 years ago and the planet is still slowly changing shape.


2. Mantle convection – large rocks in the Earth’s core are moving over each other and making the planet wobble.


3. Humans – we’re to blame for the last reason, say NASA. This is because of man-made climate change that has seen ice caps melting and causing 7,500 gigatons of ice to drift into the ocean from Greenland. That weight change could have contributed to the wobble.

The wobble does not pose a major threat to life. It does, however, create challenges for navigation.

But technology can compensate for our wobbly planet. You can see an interactive demo on NASA’s Polar Motion Simulator.

To achieve her kick-ass figure, Hayden – who plays cheerleader Claire Bennet in Heroes – follows the ‘quartering’ rule. She eats only a quarter of the food on her plate, then waits 20 minutes before deciding whether she needs to eat again.

Hayden says: “I don’t have a model’s body, but I’m not one of those crazy girls who thinks that they’re fat. I’m OK with what I have.”

Nicollette says: “I don’t like diets – I see it, I eat it! I believe in eating healthily with lots of protein, vegetables and carbs to give you energy.”

SATC star Kim swears by gym sessions with Russian kettle bells (traditional cast-iron weights) and the South Beach Diet to give her the body she wants. To avoid overeating, Kim has a radical diet trick – squirting lemon juice on her leftovers – so she won’t carry on picking.

Kim says: “I am no super-thin Hollywood actress. I am built for men who like women to look like women.”
