We are finally back from Greenland, bringing to a close the data collection piece of the spring 2010 Ice Bridge campaign. During my month-long piece in this campaign our time was split between two West Greenland base -camps, Kangerlussuaq and Thule (also known as Qaanaaq). Thule, at the northern end of Greenland, is the farthest…

Otherwise, all that work was for nothing. Here are some images showing how we handle them initially. (Courtesy David Christenson/Freeport McMoRan)

Permaculture has many facets, but one of the most exciting is its approach to water. Permaculture designers believe that through intelligent landscape design, it is frequently possible to go beyond conservation of water to actually recharge groundwater supplies.
A string of recent polls have heralded the decline of American interest in climate change: fewer people believe in it, fewer people see it as a serious problem, and more people think scientists don’t agree about it. Coupled with recent scandals over hacked emails and allegations of inaccuracy in the IPCC, these polls seem to…

Proper sanitation facilities are also rare, particularly in informal settlements and peri-urban areas. Despite the valiant efforts by local and national governments, international NGOs, foundations and corporations to bring clean water and sanitation facilities to sub-Saharan…
Small Stresses Might Bring Big Results, Says Study
Last month, Columbia’s Lamont-Doherty Earth Observatory hosted a conference on dust in the climate system as part of the NOAA funded Abrupt Climate Change in a Warming World (ACCWW) project. Most often, we think of dust simply as the stuff that accumulates on our windowsills, but those fine particles floating in the air play an…
In a place like Iraq, our attention is on the big issues, and we might forget that life also goes on for regular people. They need to grow crops and wash dishes and make tea. For many people in the country, those mundane things can be every bit as big an issue. If you don’t…
