Two years ago this month, an edge-pushing environmental entrepreneur and a company formed by a Native Canadian village set off a wave of international protest by dispersing a pink slurry of 100 tons of iron-rich dust over one of the 60-mile-wide ...

There is no scientific silver bullet that will save the world from the effects of climate change, a new study says. Over the past two years, a team of Canadian and American researchers has evaluated the potential for so-called ...   
23/5/2014
A decade ago, a common hypothesis was that rivers and dust supplied the ocean with most of its iron. Since then, scientists have reported in several papers that icebergs and deep-sea hydrothermal vents also may be significant ...   
26/2/2014
With global greenhouse gas emissions continuing to increase proposals to limit the effects of climate change through the large-scale manipulation of Earth system are increasingly being discussed. Researchers at the GEOMAR Helmholtz Centre for ...

Though scientists and environmentalists often feel obligated to hawk the apocalyptic view of the world-to-come, there is a neglected version of the future well worth considering: the one where we win. British environmentalist Jonathon ...

When U.S. Rep. Brian Baird tried a few years ago to get his colleagues to put more money toward ocean-acidification research, few even understood the issue. One congressman, Baird said, confused souring seas with acid rain, and asked, ...   
9/1/2014
In 1991, Mount Pinatubo in the Philippines erupted in one of the largest volcanic blasts of the 20th century. It spat up to 20 million tons of sulfur into the upper atmosphere, shielding the earth from the sun’s rays and causing global ...

In the summer of 2012, a small group of the Haida people, a native community in Canada, had a problem. The salmon they rely on were disappearing. So the Haida took matters into their own hands.They partnered with an American businessman, ...   
20/10/2013
Two years ago this month, in a disused UK airfield, scientists were preparing to undertake one of the more controversial experiments in history. A dirigible balloon would spray 120litres of water droplets into the sky, a miniaturized test for a ...   
29/8/2013
Last year the Haida, an indigenous group in Canada, set out to increase their salmon stocks and save the planet. Helped by American businessman Russ George, a group of villagers dumped 100 metric tons (110.23 tons) of iron dust from a boat into ...   
31/7/2013
Researchers are exploring ways to possibly change Earth's atmosphere to counteract climate change. Will they work, and at what cost and what trade-offs?It sounds like weird science, but experts — and the CIA — are investigating whether ...   
14/6/2013
If Bill Gates was so inclined, he could reduce the world’s temperature by one degree. All it would takes is a fleet of high altitude planes, releasing millions of tonnes of sulphur dioxide into the stratosphere, deflecting the sun’s rays ...   
8/4/2013
Scientists from Cardiff University and the University of Barcelona have discovered new clues about past rapid climate change. The research, published this month in the journal Nature Geoscience, concludes that oceanographic ...   
29/3/2013
Environment Canada's enforcement branch has executed search warrants in British Columbia as part of an investigation into a controversial iron-fertilization experiment that took place off the coast of Haida Gwaii, B.C., last summer, CBC's the ...   
22/3/2013
Geoengineering schemes that aim to slow global warming by seeding oceans with iron to boost carbon dioxide-absorbing phytoplankton may not lead to long-term sequestration of the important greenhouse gas, finds a new study published in the journal ...   
28/1/2013
Near the outer tip of Cape Cod, a small cottage faces west across the bay toward the mainland. Built in 1950, it measures 776 square feet – smaller than many one-bedroom apartments. It has no garage and sits on less than an acre of land at the ...   
24/1/2013
Installing a giant mirror in space to block sunlight, dispersing mass quantities of minerals into the oceans to suck carbon dioxide from the air and infusing the Earth’s upper atmosphere with sun-reflecting chemicals might sound like the stuff of ...   
10/1/2013
Perennial biofuel crops such as miscanthus, whose high yields have led them to be considered an eventual alternative to corn in producing ethanol, are now shown to have another beneficial characteristic -- the ability to reduce the escape of ...   
19/12/2012
Numerous geo-engineering schemes have been suggested as possible ways to reduce levels of the greenhouse gas carbon dioxide in the atmosphere and so reduce the risk of global warming and climate change. One such technology involves dispersing ...   
7/11/2012
Environmental officials in Canada are investigating what some have called a "rogue climate change experiment." Over the summer, a native village on the coast of British Columbia dumped more than 100 tons of iron sulfate into the ocean. The idea ...   
28/10/2012
FOR almost 20 years, I’ve been spending time on a craggy stretch of British Columbia’s shoreline called the Sunshine Coast. This summer, I had an experience that reminded me why I love this place, and why I chose to have a child in this sparsely ...   
26/10/2012
A small British Columbia First Nation making waves around the world with a controversial experiment in the Pacific Ocean is on the front lines of climate change, critics admit. And as the fears of global warming grow, there is a risk ...

Pacific Ocean hacker speaks out, Scientific American
This past July Russ George served as chief scientist on a cruise to fertilize the northeastern Pacific Ocean with iron—the latest in a long string of similar, and usually controversial, efforts he has led. He has been attempting to commercialize ...   
25/10/2012
In a bid to restore lost fish abundance, the Haida Salmon Restoration Corp. (HSRC) undertook to mimic the effects of a volcanic eruption by fertilizing the ocean with iron. The idea was to provide the missing nutrient for a plankton bloom that ...   
23/10/2012
Harvard's David Keith calls it the "goofy Goldfinger scenario' -- a rogue nation, or even an individual, would conduct an unsupervised geoengineering experiment -- and he confidently predicted in a story I wrote last month that it would never ...
