A Rash of Proposals Emerges to Transfer Excess Carbon into the Ocean
It's sort of the planetary equivalent of moving clutter accumulating in the attic to other storage space in the basement: transferring excess heat-trapping carbon dioxide from Earth's atmosphere into the deep ocean. A combination of forces--including...
Dumping Iron and Trading Carbon
Profits, pollution, and politics all will play roles in ocean iron fertilizationDebating the idea of fertilizing the ocean with iron can feel a little like riding a seesaw.On the up side is iron's eye-catching potential to set off enormous plankton blooms,...
Dumping Iron and Trading Carbon: Profits, Pollution, and Politics All Will Play Roles in Ocean Iron Fertilization
Debating the idea of fertilizing the ocean with iron can feel a little like riding a seesaw. On the up side is iron's eye-catching potential to set off enormous plankton blooms, triggering large reductions in atmospheric carbon dioxide. But further...
Fertilizing the Ocean with Iron
Is this a viable way to help reduce carbon dioxide levels in the atmosphere?"Give me half a tanker of iron, and I'll give you an ice age" may rank as the catchiest line ever uttered by a biogeochemist. The man responsible was the late John Martin, former...
Fertilizing the Ocean with Iron: Is This a Viable Way to Help Reduce Carbon Dioxide Levels in the Atmosphere?
"Give me half a tanker of iron, and I'll give you an ice age" may rank as the catchiest lilac ever uttered by a biogeochemist. The man responsible was the late John Martin, former director of the Moss Landing Marine Laboratory, who discovered that...
Lessons from Nature, Models, and the Past
Other lines of evidence inform the debate on ocean iron fertilizationThe first part of biogeochemist John Martin's famous prediction-"Give me half a tanker of iron, and I'll give you an ice age"-has been proved partly right: Iron is the only thing standing...
Lessons from Nature, Models, and the Past: Other Lines of Evidence Inform the Debate on Ocean Iron Fertilization
The first part of biogeochemist John Martin's famous prediction--"Give me half a tanker of iron, and I'll give you an ice age"--has been proved partly right: Iron is the only thing standing in the way of plankton blooms in some regions of the ocean....
To Fertilize, or Not to Fertilize
Global warming is "unequivocal," the Intergovernmental Panel on Climate Change (IPCC) reported in November 2007. Human actions--particularly the burning of fossil fuels--have dramatically raised carbon dioxide and other greenhouse gases in the atmosphere,...
What Are the Possible Side Effects?
The uncertainties and unintended consequences of manipulating ecosystemsMost of the ocean food chain is too small to see, but that doesn't mean the effects of iron fertilization will be, too."The purpose, if one is going to do iron fertilization, is...
What Are the Possible Side Effects? the Uncertainties and Unintended Consequences of Manipulating Ecosystems
Most of the ocean food chain is too small to see, but that doesn't mean the effects of iron fertilization will be, too. "The purpose, if one is going to do iron fertilization, is to increase the amount of marine biology and to increase phytoplankton...
Will Ocean Iron Fertilization Work?
Getting carbon into the ocean is one thing. Keeping it there is another.In this age of satellites, it's fairly easy to answer the basic question of whether adding iron to the ocean can stimulate a plankton bloom. When storms over land blow iron-rich...
Will Ocean Iron Fertilization Work? Getting Carbon into the Ocean Is One Thing. Keeping It There Is Another
[ILLUSTRATION OMITTED] In this age of satellites, it's fairly easy to answer the basic question of whether adding iron to the ocean can stimulate a plankton bloom. When storms over land blow iron-rich dust into the sea, satellite images show marbled...
