5th August 2015, 10:30 in the morning. The meeting had to be interrupted to take this picture. We were aboard the Swedish icebreaker Oden, and were now closer than anyone before to the terminus of Petermann Glacier in northwestern Greenland. But we had not travelled that far just for pictures… Petermann’s ice tongue Petermann is one of Greenland’s largest “marine terminating glaciers”. As the name ...[Read More]

Post by WaterUnderground contributors Elco Luijendijk and Stefan Peters from the University of Göttingen, in Germany. After my first ever scientific presentation, someone in the audience asked a question that caught me off guard: “Where does the groundwater come from?”. “Ehm, from rainfall”, I answered. The answer seemed obvious at the time. However, we did not realize at the time that this is a ...[Read More]
It might seem obvious that a warming world will lead to a reduction in glacial ice cover, but predicting the response of glaciers to climatic change is no simple task (even within the short term). One way to approach this problem is to come up with relationships which describe how glaciers interact with the world around them, for example, how the ice interacts with the air above it. Our post today ...[Read More]

Making room for growing populations, and the resources they demand, comes at the cost of precious natural environments. Rainforests, globally, are under threat from farming, logging and ever expanding cities. It is reported that if current rates of exploitation continue, the world’s rainforests could be lost within the next century. Like almost anything else, rainforests come in all shapes a ...[Read More]
Declining sea ice in the Arctic is definitely one of the most iconic consequences of climate change. In a study recently published in Science, Dirk Notz and Julienne Stroeve find a linear relationship between carbon dioxide (CO2) emissions and loss of Arctic sea-ice area in summer. Our image of this week is based on these results and shows the area of September Arctic sea ice lost per inhabitant d ...[Read More]

“It’s snowing still,” said Eeyore gloomily. “So it is.” “And freezing.” “Is it?” “Yes,” said Eeyore. “However,” he said, brightening up a little, “we haven’t had an earthquake lately.” A.A. Milne, The House at Pooh Corner (1928) The above is a quote from one of two classic Winnie-the-Pooh books by A. A. Milne. Upon ...[Read More]
