It's very clear that global climate change is occurring on earth, but it's also been very clear that that has always happened on earth. We've always had a changing climate on earth. We all know about ice ages. We know when our continent was covered with ice sheets. We know glaciers come and they go. It puzzles me that people forget that.

But with the slow menace of a glacier, depression came on. No one had any measure of its progress; no one had any plan for stopping it. Everyone tried to get out of its way.

You could engineer a human to survive the greenhouse effect because you think that's what's going to happen, and then all of a sudden the glaciers are creeping down on you.

Is there climate change? I live in the shadow of some of the greatest climate change the world has ever seen. It's called the Rocky Mountains. When the glaciers went back.

We try to make children problem-solvers. That gave birth to solar-heated mud buildings, using greenhouses to grow things and ice stupas - artificial baby glaciers.

In the Andes and the Alps, I have seen melting glaciers. At both of the Earth's Poles, I have seen open sea where ice once dominated the horizon.

The museum at Ortles is dedicated to the world of ice so we wanted visitors to feel like they were inside a glacier.

This air we breathe is precious, and the glaciers helped me understand that and stay focused on that.

Pain reaches the heart with electrical speed, but truth moves to the heart as slowly as a glacier.

Donella Meadows

Glaciers are almost gone from Glacier National Park.

American Environmentalist

Glaciers are made of compacted snow, not just frozen water like ice cubes.

Not Just Ice

Though glaciers move slowly, they can reshape the earth's surface over time.

Slow Movement

Glaciers are sensitive to climate changes, often used as indicators of global warming.

Climate Indicator

Glacial periods tell us about the Earth's climatic history and prehistoric times.

Past Climates

A glacial period can significantly affect sea levels and landforms worldwide.

Geological Changes

When people say 'Ice Age', they often mean a time with many glacial periods.

Ice Age Reference

 Here are some thing you might not know about the icy islands. The life of an iceberg begins many thousands of years before it reaches the ocean. Unlike sea ice or pack ice, which form when the ocean freezes, glaciers are made of fresh water. For thousands of years, these glaciers build layer upon layer of ice,

 At the end of this hole, we found a huge tunnel going right up the mountain underneath thousands of tons of glacier ice. We followed this cave back for about a half mile until it came to an end. And then with the help of our survey tools, we made a three-dimensional map of the cave on our way back out.

 and the glaciers that cloaked the Earth's surface began their slow retreat. These immense ice sheets carved out a series of basins. Those basins filled with water as the ice began to melt, creating the world's largest area of freshwater lakes. Over time, channels developed between these basins,

 - Glaciers have been shaping our world for millions of years. But as climate change warms the planet, glaciers are disappearing, not only altering the landscapes they leave behind, but changing our oceans, weather, and life on earth as we know it.
