Germany? environment ministry on Wednesday took aim at a controversial experiment to see whether the ocean can be primed to become a sponge for soaking up dangerous greenhouse gases.
The geo-engineering scheme ?bitterly attacked by environmentalists ?is being conducted by a joint German-Indian research team aboard a German vessel who say they are not breaking any rules or damaging the ecosystem.
The scientists aim to discharge 6 tonnes of iron sulphate in the south Atlantic to find out how this affects microscopic marine plants on the ocean surface.
Proponents believe iron nutrition will cause this phytoplankton to grow explosively and thus absorb more atmospheric carbon dioxide, the principal greenhouse gas, as a result of photosynthesis.
It could become an invaluable buffer against global warming, they argue.
CATASTROPHIC
Opponents, though, say the consequences of wide-scale iron fertilization could be catastrophic. They fear it could cause the sea to become more acidic or trigger algal blooms that would de-oxygenate swathes of the ocean.
Environment ministry spokesman Matthias Machnig said on Wednesday that the ministry had asked the German research ministry to ?mmediately halt?the experiment.
The test runs counter to a global moratorium on ocean fertilization established under the UN Convention on Biological Diversity (CBD), Machnig said.
The regional daily the Maerkische Allgemeine reported that German Environment Minister Sigmar Gabriel had also written to Research Minister Annette Schavan, saying the experiment ?estroys Germany? credibility and its vanguard role in protecting biodiversity.?br />
However, the research ministry told Agence France-Presse that it believed the German institute in question, the Alfred Wegener Institute (AWI), ?ad prior agreement with the environment ministry?for carrying out the experiment.
EXPERIMENT
The iron-sowing expedition, named LOHAFEX, comprises 48 scientists, 30 of them from India? National Institute of Oceanography (NIO), aboard the research ship Polarstern.
The team set sail from Cape Town on Jan. 7 and after two weeks will arrive in a target zone where the dissolved iron will be discharged over a patch of 300km? The zone has not been identified. After research, the ship will dock in Punta Arenas, Chile, on March 17.
In a press statement, the Bremerhaven-based AWI said that the experiment ?s in accordance?with the provisions of the CBD and the London Convention on ocean fertilization ?hat call for further research to enhance understanding of ocean iron fertilization.?br />
Planning for the experiment began in 2005 and the scheme was part of a memorandum of understanding between the AWI and NIO that the two institutes signed during a trip to New Delhi in October 2007 by German Chancellor Angela Merkel, the statement said.
?he size of the fertilized patch is considerably smaller than the impact of melting icebergs that may leave a swathe of several hundred kilometers breadth of enhanced iron concentrations,?AWI said.
?OHAFEX will contribute legitimate and much-needed scientific research to the controversial discussions on ocean fertilization,?it said.
Once written off as irresponsible or madcap, geo-engineering schemes are getting a closer hearing in the absence of political progress to roll back the greenhouse gas problem.
FLOATING MIRRORS
Other, far less advanced, projects include sowing sulphur particles in the stratosphere to reflect solar radiation and erecting mirrors in orbit that would deflect sunrays and thus slightly cool the planet.
Green groups are concerned by these projects and say they could cause more problems than they resolve. They also say these schemes?financial cost is unknown, but possibly far more than the bill for reducing emissions that cause the problem.
?his case clearly shows why we need strong, enforceable rules to prevent rogue geo-engineers from unilaterally tinkering with the planet,?said Jim Thomas of the ETC Group, an environmental watchdog based in Montreal, Canada.
When Shanghai-based designer Guo Qingshan posted a vacation photo on Valentine’s Day and captioned it “Puppy Mountain,” it became a sensation in China and even created a tourist destination. Guo had gone on a hike while visiting his hometown of Yichang in central China’s Hubei Province late last month. When reviewing the photographs, he saw something he had not noticed before: A mountain shaped like a dog’s head rested on the ground next to the Yangtze River, its snout perched at the water’s edge. “It was so magical and cute. I was so excited and happy when I discovered it,” Guo said.
Chinese authorities said they began live-fire exercises in the Gulf of Tonkin on Monday, only days after Vietnam announced a new line marking what it considers its territory in the body of water between the nations. The Chinese Maritime Safety Administration said the exercises would be focused on the Beibu Gulf area, closer to the Chinese side of the Gulf of Tonkin, and would run until tomorrow evening. It gave no further details, but the drills follow an announcement last week by Vietnam establishing a baseline used to calculate the width of its territorial waters in the Gulf of Tonkin.

TURNAROUND: The Liberal Party had trailed the Conservatives by a wide margin, but that was before Trump threatened to make Canada the US’ 51st state Canada’s ruling Liberals, who a few weeks ago looked certain to lose an election this year, are mounting a major comeback amid the threat of US tariffs and are tied with their rival Conservatives, according to three new polls. An Ipsos survey released late on Tuesday showed that the left-leaning Liberals have 38 percent public support and the official opposition center-right Conservatives have 36 percent. The Liberals have overturned a 26-point deficit in six weeks, and run advertisements comparing the Conservative leader to Trump. The Conservative strategy had long been to attack unpopular Canadian Prime Minister Justin Trudeau, but last month he
Four decades after they were forced apart, US-raised Adamary Garcia and her birth mother on Saturday fell into each other’s arms at the airport in Santiago, Chile. Without speaking, they embraced tearfully: A rare reunification for one the thousands of Chileans taken from their mothers as babies and given up for adoption abroad. “The worst is over,” Edita Bizama, 64, said as she beheld her daughter for the first time since her birth 41 years ago. Garcia had flown to Santiago with four other women born in Chile and adopted in the US. Reports have estimated there were 20,000 such cases from 1950 to
