Sometime last fall, I had a bad dream. I was visiting my field site, Portage Glacier, and checking on the instrumentation that I had – in real life – installed during the summer a couple months prior. In the dream, I took the field computer, plugged in one of the […]

Volcanoes can have major impacts on the climate system, resulting in short-term cooling of earth’s surface following an eruption. Amongst the most active regions in the world is Iceland, the activity of which is reflected in its extremely diverse and largely desolate landscape. However, despite the high-activity of these volcanic […]

Ice mass loss from Greenland has accelerated over the last few decades and it has recently been predicted that Greenland could become ice free in the next millennium. During past interglacial periods, when global mean temperatures reached values larger than today, the Greenland Ice Sheet was most likely smaller than […]

Arctic rivers and their deltas are increasingly impacted by the rapid changes the Northern regions are currently facing. The Canadian Northwest Territories have witnessed dramatic increases in temperature and precipitation over the last decade, leading to widespread thawing of previously frozen soils (permafrost). To investigate whether this changing climate has […]
