The idea is surprisingly simple. Since iron is a well-known way to get phytoplankton to bloom, scientists suggest we could slightly increase the presence of the metal by adding bits of iron to iron-deficient parts of the oceans. The more phytoplankton, the more carbon dioxide gets sucked up by our oceans — a seductively simple and inexpensive idea that could, potentially, make all the difference. "Give me half a tanker of iron, and I’ll give you an ice age," wrote oceanographer John Martin back in the 1980s, in a [paper]() dug up by the *Beast*. ## Green Oceans The concept dates [back several decades](), when scientists were only beginning to understand the concept of climate change. Now, some researchers are trying to revive the idea. In a [2021 report](), a team of scientists evaluated a number of options to make use of the planet's oceans to fight climate change — including increasing the levels of phytoplankton. "We’ve got a big reservoir," Ken Buesseler, a marine radiochemist at the Woods Hole Oceanographic Institution, who worked on the report, told the *Beast*. "It takes up a third of the greenhouse gasses already. The question that people are now asking more is what can we do to enhance that?" "Let’s get out there," he added. "Let’s do experiments." ## Pumping Iron The iron technique also has the benefit of being pretty cheap. Iron ore could literally be dropped into the water from ships, resulting in blooms that are visible from space, according to experts who spoke with the *Beast*. Best of all, the change would be apparent almost instantly, with phytoplankton blooming even in the first 24 hours. The exact logistical cost and effort to pull such a scheme off remain hazy, and it's unclear how much of the greenhouse effect a concerted effort would be able to ameliorate. But with climate change [looming larger every year](), it's probably worth investigating further. **READ MORE:** [The Mad Plan to Save Earth by Flooding It With Phytoplankton]() \[*The Daily Beast*\] **More on plankton:** *[Researchers Claim Collapsing Ocean Ecosystem Will Will Devastate Humanity Within 25 Years]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
