Climate change top ocean stressor: Study Last Updated on 2015-07-17 10:04:35       Climate change is the largest human-caused stressor on the world's oceans, according to a new study published in the journal Nature. Of the areas observed in the study, about two-thirds of ocean and 77 percent of waters in national exclusive economic zones experienced increased harm from human activity, based on a comparison of data between 2008 and 2013. Almost all of those detrimental effects on marine ecosystems came from climate change, rather than other practices such as fishing, pollution and agricultural runoff. "The many stressors associated with climate change (anomalously high sea surface temperatures, ocean acidification and increasing ultraviolet radiation) dominate humanity's footprint on the open ocean, but commercial fishing and shipping also cover large areas of the oceans and contribute significantly to overall impact," said...

Solar-Powered Water Wheel Can Clean 50,000 Pounds of Baltimore‚Äôs Trash Per Day Last Updated on 2015-02-04 19:33:30 This post first appeared on EcoWatch. A large wheel has been strolling the Baltimore Inner Harbor this summer, doing its best to clean the trash that has littered a city landmark and tourist attraction. It’s called the Inner Harbor Water Wheel, and though it moves slowly, it has the capability to collect 50,000 pounds of trash. The timing for John Kellett’s solar-powered creation is crucial — hands and crab nets simply can’t keep up with the growing amount of wrappers, cigarette butts, bottles and other debris carried from storm drains into the harbor. “It looks sort of like a cross between a spaceship and a covered wagon and an old mill,” Kellett told NPR. “It’s pretty unique in its look, but it’s also doing a really good job getting this trash out of the water.” The wheel has become an integral part of the Healthy...

Last Hours Last Updated on 2014-09-23 14:28:35 The film “Last Hours” is the 2nd film in the Green World Rising Series ( the first one is "Carbon" that is available on this channel). Last Hours describes a science-based climate scenario where a tipping point to runaway climate change is triggered by massive releases of frozen methane. Methane, a powerful greenhouse gas, has already started to percolate into the open seas and atmosphere from methane hydrate deposits beneath melting arctic ice, from the warming northern-hemisphere tundra, and from worldwide continental-shelf undersea methane pools. Burning fossil fuels release carbon that, principally through greenhouse effect, heat the atmosphere and the seas. This is happening most rapidly at the polar extremes, and this heating has already begun the process of releasing methane. If we do not begin to significantly curtail the use of carbon-based fossil fuels,... More »
