Imaggeo on Mondays: Heavy machinery

How do you get heavy machinery, such as a drill spool onto an ice sheet? This week’s imaggeo on Mondays’ photography captures the freighting of components of a hot water drill to directly access and observe the physical and geothermal properties at the ice-bed interface. In the image, SAFIRE principal investigator Bryn Hubbard and post-doc Sam Doyle help fly in the drill spool at the start of the Summer 2014 field campaign on Store Glacier, Western Greenland. Freighting several [...]

I spent the weekend reading the new paper in Nature last week that made a lot of news. (Justin Gillis at The NY Times has an excellent summary of the paper here). If you missed it, the short version is that for the first time, researchers used a series of coupled models to produce a more realistic look at what will happen to Antarctica in the coming decades and centuries.

One Million Icequakes

Nestled in the Arctic is a glacier like no other. This glacier quakes once a minute creating seismic events that rattle the earth—more frequently than scientists have ever seen. Understanding why these icequakes are so common may help researchers predict future ice flow, a process that propels climate-driven sea level

Will coral reefs and atolls (coral islands) be able to keep pace with the current and projected sea level rise and remain geologically stable in the coming decades and centuries? Will atolls in  the Pacific and Indian Oceans remain habitable? Regarding  the first question,  I came  across a couple of recent  studies that suggest that reef growth in the Pacific, Indian and Caribbean seas

While the ice sheets on West Antarctica and the Antarctic Peninsula are usually the ones to make the news in relation to climate change, recent studies have documented transformations that are taking place on the East Antarctic Ice Sheet as well. On the continent as a whole, large areas of ice have already melted and this trend shows no sign of slowing, meaning the implications for global sea level rise in this century could be more dramatic than earlier projections

Trying to define pornography, a frustrated U.S. Supreme Court Justice Potter Stewart once famously declared “I know it when I see it”, and perhaps you can say the same thing about critical thinking. Greg Laden (at Science Blogs) wrote a great post today about Bjorn Lomborg, a “famous” climate denier, and a statement he made about sea level rise. Laden then goes on to show just how ridiculous the argument

Glaciers in one part of West Antarctica are melting at triple the rate of a decade ago and have become the most significant contributor to sea level rise in that region, a new study says. The study found that the glaciers in the Amundsen Sea Embayment of West Antarctica have shrunk by an average of 83 gigatons a year for two decades—the equivalent of the weight of Mount Everest every two

The Earth’s surface temperatures can have a profound effect on the Earth’s ice sheets, the huge layers of ice thousands of metres thick that cover Greenland and Antarctica. Over the past few decades, satellites have monitored the changes of these icy landscapes, revealing that parts of Greenland and West Antarctica are melting. This is important as it contributes to sea level rise, which can have significant impacts on vulnerable coastal lands. So far, however, East Antarctica’s ice [...]

Up to $106 billion worth of coastal homes and businesses in the U.S. are likely to be underwater by the year 2050 due to rising sea levels, and up to $507 billion in coastal property will likely be below sea level by 2100, according to a new report released today. The report is based in part on a new study on sea level rise in Earth’s Future, a journal of the American Geophysical

“A new study has found that the Antarctic Ice Sheet began melting about 5,000 years earlier than previously thought coming out of the last ice age – and that shrinkage of the vast ice sheet accelerated during eight distinct episodes, causing rapid sea level rise.” Quoted from the Oregon State University press
