Future continuous

and you'll be moving out 1,670 kilometers per hour,

That's how quickly Earth rotates on its axis from west to east,

for the distribution of every desert, forest, and swamp on the planet.

Let's say we reverse Earth's rotation, what then?

This may seem like a ridiculous scenario at first,

but scientists have actually run simulations for a backward-spinning Earth,

because it happens to be a great way to test how well we can model our planet.

So, let's pretend we have a big, red button, and ... presto!

Now, as Earth slows down to reverse direction

so the whole process will leave a huge mess.

which normally blow westward due to Earth's rotation.

At first, changes would be relatively small.

Hurricanes, for example, would no longer travel

and westbound flights would suddenly be much shorter compared to eastbound.

Let's fast forward a few thousand years into the future.

would turn Africa's Sahara Desert from this,

that the deserts of the world would shrink

from 42 million square kilometers to 31 million,

providing new plant life which would absorb

potentially offsetting the extreme warming effects

from climate change. Wow, maybe we really should

But hold on, if the trade winds reverse direction,

it means that other wind patterns change too,

that normally blow east across the Northern Atlantic,

to Northwest Europe, keeping winters mild.

But on backwards Earth, the westerlies reverse,

As a result, scientists estimate winter temperatures

In fact, most of the North Atlantic would grow colder.

which normally transports warm tropic waters

In North America, the landscape would change drastically.

For example the iconic deserts of the American Southwest

to the beautiful new green pastures of Arizona,

and enjoy that peculiar sunset to the east.
