Why are news outlets ignoring the fact that the future of our planet is at risk?

We're seeing record high temperatures year after year.

So why did coverage of climate change drop by 66% on broadcast news?

Climate change is already wreaking havoc around the world.

Here's what happens:

Let's say a natural disaster takes place where you and your family live.

It could be a tornado, flood, snowstorm or drought, which will only become more frequent.

It gets so bad that you need to move to another part of the country or another country entirely.

You will either be internally displaced or a refugee.

But you can't even apply for asylum or refugee status, because the 1951 Refugee Convention

does not include climate change as a reason for fleeing.

As a woman, you're even more at risk because of climate change.

Studies have shown that women will bear the brunt of natural disasters.

And natural disasters kill more women than men.

And if you're a pregnant woman, you're even more prone to malaria, heat stress and dehydration.

For example, in Somaliland, a three-month long drought has forced many to migrate, and

migrating is even riskier as a woman, because women face "violence, assault, exploitation and

sexual harassment at every stage of their journey."

Even once they get to a new camp, they are still at risk for sexual assault.

If they make it to a city, they have fewer employment opportunities compared to men,

because they are often expected to be the sole caregivers for their families.

Climate change is already affecting the United States, too.

It is already forcing the community of Isle de Jean Charles in southeastern Louisiana

to begin relocating as it is literally sinking into the Gulf of Mexico.

Climate change is also extremely expensive.

The federal government had to set aside $48 million in grants to resettle the residents

of Isle de Jean Charles.

And in the United States alone, more than 5,790 square miles and more than $1 trillion

of property are threatened by rising sea levels.

And by the way, a note to the president, half of this vulnerable property value is located

in Florida.

The majority of Americans think we should take action to combat global climate change,

and it's the media's job to tell the truth about what's happening in the world.

Climate change is happening.

Tell that story.

Bubble of Spacetime A 'Time Machine' That Moves Greater Than - tech and science - Duration: 4:47.

Bubble of Spacetime --"A 'Time Machine' That Moves Greater Than Speed of Light Allowing

It to Travel Back and Forward in Time"

After some serious number crunching, a University of British Columbia researcher has come up

with a mathematical model for a viable time machine --a bubble of space-time geometry

which carries its contents backward and forwards through space and time as it tours a large

circular path.

The bubble moves through space-time at speeds greater than the speed of light at times,

allowing it to move backward in time.

Ben Tippett, a mathematics and physics instructor, whose field of expertise is Einstein's theory

of general relativity, studies black holes and science fiction when he's not teaching.

Using math and physics, he has created a formula that describes a method for time travel.

"People think of time travel as something as fiction," says Tippett.

"And we tend to think it's not possible because we don't actually do it.

But, mathematically, it is possible."

Ever since HG Wells published his book Time Machine in 1885, people have been curious

about time travel--and scientists have worked to solve or disprove the theory, he says.

In 1915 Albert Einstein announced his theory of general relativity, stating that gravitational

fields are caused by distortions in the fabric of space and time.

More than 100 years later, the LIGO Scientific Collaboration--an international team of physics

institutes and research groups--announced the detection of gravitational waves generated

by colliding black holes billions of lightyears away, confirming Einstein's theory.

The division of space into three dimensions, with time in a separate dimension by itself,

is incorrect, says Tippett.

The four dimensions should be imagined simultaneously, where different directions are connected,

as a space-time continuum.

Using Einstein's theory, Tippett says that the curvature of space-time accounts for the

curved orbits of the planets.

In "flat" -- or uncurved -- space-time, planets and stars would move in straight lines.

In the vicinity of a massive star, space-time geometry becomes curved and the straight trajectories

of nearby planets will follow the curvature and bend around star.

"The time direction of the space-time surface also shows curvature.

There is evidence showing the closer to a black hole we get, time moves slower," says

Tippett.

"My model of a time machine uses the curved space-time -- to bend time into a circle for

the passengers, not in a straight line.

That circle takes us back in time."

While it is possible to describe this type of time travel using a mathematical equation,

Tippett doubts that anyone will ever build a machine to make it work.

"HG Wells popularized the term 'time machine' and he left people with the thought that an

explorer would need a 'machine or special box' to actually accomplish time travel,"

Tippett says.

"While is it mathematically feasible, it is not yet possible to build a space-time machine

because we need materials--which we call exotic matter--to bend space-time in these impossible

ways, but they have yet to be discovered."

For his research, Tippett created a mathematical model of a Traversable Acausal Retrograde

Domain in Space-time (TARDIS).

He describes it as a bubble of space-time geometry which carries its contents backward

and forwards through space and time as it tours a large circular path.

The bubble moves through space-time at speeds greater than the speed of light at times,

allowing it to move backward in time.

"Studying space-time is both fascinating and problematic.

And it's also a fun way to use math and physics," says Tippett.

"Experts in my field have been exploring the possibility of mathematical time machines

since 1949.

And my research presents a new method for doing it."

of Hubble into Earth orbit by the STS-31 space shuttle crew on April 24, 1990.
