If you notice, the summit of Everest is black.

The weather was so cold that the lake froze over.

It was so cold that the lake froze over.

And these plants need sunlight, so we know when we find that sediment there's no ice overhead.

Let's talk about the Arctic first.

New York City, Chicago, Seattle, all under a sheet of ice.

Sad picture.

And just like the polar bears, these animals depend on an icy environment.

So he was there when I woke up, and it was, waking up was like breaking through the ice into a frozen lake of pain.

The continental landmasses drifted around.

It's the fifth largest continent on the planet at nearly twice the size of Australia.

And curious to see if any of them made any noise,

Particularly Mars, but also Europa, the small, icy moon around Jupiter.

It's about a meter tall Pavona clavus colony.

For several thousand years, global average temperatures stayed 15 degrees Fahrenheit, that's about 8 degrees celcius below what they're today, and mile thick glaciers covered much of North America, Europe, and Asia outside the ice covered regions, it was so dry that survival became difficult in most areas.

Icebergs are born when they calve off of glaciers or break off of ice shelves.

Those 4 degrees meant that 30 percent of the land area of the world was covered in ice.

To look at a vast expanse of open water at the top of our world that used to be covered by ice.

To a dark place this line of thought will carry us.

The hill lay covered with snow.

At night they get covered in pollen, which showers down over them, and then the bristles that we saw above, they sort of wilt and allow all these midges out, covered in pollen fabulous thing.

And, pull out to side.

Ice 3.0. the refrigerator curve.

A si iDhuath úorthor, Aragorn. (The shadow does not hold sway yet, Aragorn)

We certainly have movement of the glacier sheets, but overall definitely colder, an icy environment, but very rich in animals as well.

We saw the ground covered with snow.

But you know, these shells, they're hard to find.

Darkness took me and I strayed out of thought and time.

The dead have been covered with lime.

I CALL THE night to witness when it covers over,

By oath of the night when it covers

By the night enshrouding

By the night when it envelopeth,

By the night as it envelops

By the night as it covers.

By the night when it enshrouds,

By the night when it envelops,

By the night, when it envelops,

By the night when it covers

By the night when it covers the day,

I swear by the night when it draws a veil,

By the night as it veils the earth in darkness,

By the Night as it conceals (the light)

Cover us with holy fear.

Take one square meter of soil and make it bare like this is down here, and I promise you, you will find it much colder at dawn and much hotter at midday than that same piece of ground if it's just covered with litter, plant litter.
