Tim Flannery is an Australian scientist and author who wrote a popular 2007 book on global warming called The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth. He has a new book out called Sunlight and Seaweed: An Argument for How to Feed, Power and Clean Up the World, which appears to be about, among other things, growing kelp on a massive scale to absorb carbon.
By the way, I don’t sell anything on this site. I’m not against selling things necessarily, but when I signed up as an Amazon affiliate nobody ever bought anything. So I’m just embedding the book covers below for convenience and because I kind of like book cover art.
