Into the Ice

ENVIRONMENT. What will happen if our Earth continues to warm? How fast will sea levels rise as glaciers melt? For decades, scientists have been trying to model and predict the effects of climate change. The equation is complex, and to solve it, we need even more data. That's why glaciologist Alun Hubbard is embarking on an expedition into the ice. He wants to know how the meltwater from our glaciers affects climate models. There are many theories but nothing definitive—yet. Alun Hubbard is hoping to elicit the answers from the ice, with measurements not just on the surface of the glacier but also inside it. In his search for evidence and data, he boldly abseils into the glacier's depths.
