No Ice Where Ice Was, Explained: headed for disaster

The poles look like a world apart, but the arrivals tell a different story. People reach places expecting expanses of sea ice and find none, and boats now reach islands once permanently locked in the ice. Under the travel log is a harder claim: "Our planet is losing its ice," and that distant ecosystem "is headed for disaster."

Qué pasa

The polar regions were beyond imagination. The speaker has watched Arctic summers warm: arrivals expecting sea ice found none, and boats now reach islands once locked in ice. The ocean can no longer absorb the excess heat from human activity. The planet is one degree warmer than when the speaker was born, summer sea ice is down 40 percent in 40 years, and the ecosystem is headed for disaster.

No Ice Where Ice Was, explicado

What's really going on

Remote habitats and scenery unlike anything else give way to a blunt turn: "But that distant world is changing." In one lifetime, Arctic summers have warmed. The visits that expected ice end in a flat report: "We have arrived at locations expecting to find expanses of sea ice and found none." Islands once "permanently locked in the ice" can now be reached by boat. By 2011, when Frozen Planet aired, the reasons were already well established. The ocean has long since been unable to absorb the excess heat from human activity. The world is one degree Celsius warmer than when the speaker was born, faster than any change in 10,000 years. Summer sea ice is down 40 percent in 40 years. "Our planet is losing its ice." The last line does not say the disaster is finished. This pristine ecosystem "is headed for disaster."

Theme

MemoryThe measure is one life: Arctic summers warmed in the speaker's time, and the world is a degree warmer than when the speaker was born.
SurvivalSpecies adapted to the extreme now face a world losing its ice, and that distant ecosystem is headed for disaster.

  • and unique species — Let and stay light and move the weight onto unique at once.

We have arrived at locations expecting to find expanses of sea ice and found none.

The point of the journey was the ice. The locations were reached, and the sea ice that was supposed to be spread out there was missing.

We've managed to travel by boat to islands that were impossible to get to historically because they were permanently locked in the ice.

Islands that history could not reach, because permanent ice sealed them in, are now accessible by boat. The barrier itself is what has changed.

The ocean has long since become unable to absorb all the excess heat caused by our activities.

The ocean's job was to take in extra heat from human activity. That ability ran out long ago, and it still has not come back.

As a result, the average global temperature today is one degree Celsius warmer than it was when I was born.

The benchmark is the speaker's own birth. Today's average global temperature is one degree Celsius higher than it was then.

Our planet is losing its ice.

A direct statement of the loss: the ice that belongs to the planet is going.

This most pristine and distant of ecosystems is headed for disaster.

Not a claim that the disaster is already over. The cleanest, most remote ecosystem is on a course toward it.

Preguntas sobre esta escena

Why can boats reach islands that used to be unreachable?

Those islands were permanently locked in the ice, which is why they were impossible to get to historically. The narration says boats have managed to reach them now.

How much warmer is the planet than when the speaker was born?

One degree Celsius. The narration links that rise to the ocean no longer absorbing all the excess heat from human activity, and says the speed exceeds any change in the last 10,000 years.

What is headed for disaster?

The most pristine and distant of ecosystems — the polar world just described. The line says it is headed for disaster, not that the disaster has already fully arrived.

Why bring up Frozen Planet and 2011?

To place the changes in time: by the time that series aired, the reasons for them were already well established.
