Alun is a glaciologist with interests in subglacial processes, ice / methane-hydrate interactions and the dynamical response of glaciers and ice sheets to atmospheric, oceanic and geological forcing. He holds an independent Arctic Five research professorship to address the long-term stability and environmental legacy of the cryosphere and its impact on global sea-level, the carbon-cycle, and broader impacts on society and landscape. His approach uses novel field-data to improve process understanding and constrain models with live projects across the Arctic, specifically focus on Greenland, Alaska and the Barents but he also works in Patagonia, Alaska, Asia and Antarctica. He has led over 60 successful research/exploration expeditions (without mishap!) across icy regions of the planet, many independently from his own sailboat and helicopter logistics non-profit company.

What’s going on with the Greenland ice sheet? It’s losing ice faster than forecast and now irreversibly committed to at least 10 inches of sea level rise

Alun Hubbard is a field glaciologist who has worked on ice sheets for more than 30 years. The past few years in particular have been unnerving for the sheer rate and magnitude of change underway. Current teachings that ice sheets respond over millennial time scales is definitely not what we’re seeing today. If every year were like 2012, when Greenland experienced a heat wave, that irreversible commitment to sea level rise would triple. That’s an ominous portent given that these are climate conditions we have already seen, not a hypothetical future scenario.
