Glaciers around the globe share with us a story of rapid change. Many are shrinking at a pace that is unprecedented since observations began, providing powerful indicators of global warming. The observed glacier changes reveal the impact that our greenhouse gas emissions have on even... click to read more

Glaciers, popularly thought of as rivers of ice, are "sentinels" of climate change — stable and persisting over centuries, they slowly respond to environmental changes. So, measuring fluctuations in glaciers provides a great way to estimate the long-term effect of changing climate. Diminishing or even... click to read more

Glaciers around the world are melting faster than in any previous decade since measurements began. Glaciers form when snow accumulates over many years and compresses into ice. Glaciers accumulate snow in the winter, and then melt ice in the summer. Cold temperatures, more snow, or both,... click to read more

In order to predict the impacts of Global Warming, scientists develop climate models that attempt to represent our real, complicated climate as closely as possible. Climate is the intertwined system of the Earth's atmosphere, ocean, and ice. If we can understand how these variables interacted... click to read more
