Indian scientists recently carried out a controversial experiment in the ocean near Antarctica to get carbon dioxide captured from the air and stored in the sea. The experiment, meant to combat climate change, was a failure, but the scientists now say they learnt some valuable lessons.
The 75-day Indo-German experiment carried out amidst opposition from environmental groups has shown that dumping iron in the Southern Ocean does not help in capturing carbon dioxide (CO2) that is responsible for much of global warming.
"We are still analysing the data, but it seems to us that ocean fertilisation is not an attractive tool to combat climate change as originally thought," Satish Shetye, director of the Goa-based National Institute of Oceanography (NIO), told IANS.
Shetye however said that the experiment which concluded six weeks ago has given new insights on how the complex ocean ecosystems function. "We have learnt a lot irrespective of whether ...
