Global change systems are evolving all around us. But is there a way to strengthen them and speed the pace of transformation to address critical issues of health, climate and poverty? In Milan last week a dozen people met for a day and a half to explore innovative frameworks to answer that question. They left with enthusiasm and a belief that the new approach holds great promise that they want to test on some specific issues.
The reasons oil prices started sliding in June were hiding in plain sight: growth in U.S. production, sputtering demand from Europe and China, Mideast violence that threatened to disrupt supplies and never did.
The Pennsylvania DOT today announced the initial winners of a new statewide competitive grant program specifically for multimodal projects and the impressive list shows just how much demand there is at the local level for these types of innovative projects.
Researchers say they have found a large fallout plume of oil on the seafloor from the 2010 Deepwater Horizon disaster in the Gulf of Mexico. According to a report in the Proceedings of the National Academy of Sciences, a portion of the 2 million barrels of oil thought to be trapped in the deep sea after the spill appears to have settled across a 1,250-square-mile patch of the seafloor centered around the Macondo Well, which discharged an estimated 5 million barrels of oil in the nearly three months between its blowout in April and eventual capping in July. The oil is concentrated in the top half-inch of the seafloor, and mostly distributed in patchy deposits to the southwest of the well, the study found. These deposits account for between 4 and 31 percent of the Macondo oil sequestered in the deep ocean, researchers estimate. The rest has likely been deposited outside this area, they say, but has evaded detection so far because of its patchiness.
Climate change presents an unprecedented challenge to the productivity and profitability of agriculture in North America. More variable weather, drought and flooding create the most obvious damage, but hot summer nights, warmer winters, longer growing
As many readers know, I am a huge fan of the American Society of Landscape Architects and their leadership on thoughtful ways to integrate nature into our cities. It’s easy to take nature for granted when we are in...
When cities devote street space exclusively to buses or trains, they usually encounter some stiff resistance to change. Dan Reed at Greater Greater Washington has been giving the topic some thought, because many of the DC region’s upcoming transit projects will require reallocating some lanes from cars to transit.
