How Melting Giant Icebergs May Help Slow Climate Change (Just A Little)
2016-01-16 21:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Huffington Post: Melting icebergs may be fighting against the very forces that cause them to melt, a new study suggests. Water dripping off icebergs and into the Antarctic Ocean, also known as the Southern Ocean, contains iron and other nutrients, according to research published Monday in the journal Nature Geoscience. These nutrients fertilize phytoplankton, the microscopic marine life that plays a key role in oceanic ecosystems, and help the tiny plants absorb carbon dioxide in the atmosphere as they grow into...
Giant Calving Icebergs May Slow Pace of Climate Change

Climate News Network: British scientists have identified the monsters that fertilise the Southern [or Antarctic] Ocean and help remove carbon dioxide from the atmosphere. Giant icebergs drifting northwards could be responsible for storing up to a fifth of all the carbon that sinks into the south polar waters. Geographers at the University of Sheffield report in Nature Geoscience journal that they analysed 175 satellite images of ocean colour-an indicator of phytoplankton activity. They learned that each huge...
Giant Icebergs Have Surprise Role in Slowing Warming
2016-01-16 16:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: The biggest icebergs breaking off Antarctica unexpectedly help to slow global warming as they melt away into the Southern Ocean, scientists said on Monday. The rare Manhattan-sized icebergs, which may become more frequent in coming decades because of climate change, release a vast trail of iron and other nutrients that act as fertilizers for algae and other tiny plant-like organisms in the ocean. These extract carbon dioxide from the atmosphere as they grow, a natural ally for human efforts to...

Giant icebergs play key role in removing carbon dioxide from atmosphere
2016-01-11 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Pioneering research from the University of Sheffield's Department of Geography discovered melting water from giant icebergs, which contains iron and other nutrients, supports hitherto unexpectedly high levels of phytoplankton growth. This activity, known as carbon sequestration, contributes to the long-term storage of atmospheric carbon dioxide, therefore helping to slow global warming. During the study, which is the first of its kind on this scale, a team of scientists led by Professor Grant...
