These icefalls are an ominous sign of what is about to happen… a rupture deep within the glacier.
A colossal iceberg is born.
This single block of ice, many hundreds of meters across, would dwarf the biggest of mankind’s buildings.
Every year, tens of thousands of icebergs are spawned by Greenland’s glaciers,
and their number is steadily increasing as the climate continues to warm.
The beak-up of the bergs fills the bays of the Arctic with exquisite ice sculptures.
It also releases great volumes of cold, fresh water into the sea.
Greenland’s melt water influences the course of the ocean currents,
which, in turn, has an effect on the weather around the world.
The Arctic is closer to home than many of us realize.
It includes the northernmost parts of the three continents on which most of us live… Europe, Asia and North America.
The first bare land we reach on our journey south is a bleak treeless wilderness known as tundra.
Each spring, animals travel up from the south, to be ready for the rich grazing that will be unveiled by the spring melt.
For the caribou, the timing is critical. Arrive early and a winter storm could kill you.
Delay too long and you may fail to lay down the fat needed to survive a polar winter.
Further south still, and stooped, shrouded figures end the flat monotony of the tundra.
This is the tree line, the first place on our journey with sufficient warmth and liquid water to enable a tree to grow.
Surviving here is so crushingly difficult, that is can take hundreds of years for a seedling to grow into a stunted shrub.
