Sunlight and Seaweed

The marvelous Prof Tim Flannery was once described by the Financial Times as akin to a cross between Charles Darwin and Indiana Jones for his pioneering mammalogy and paleontology field work. But he gave up this adventurous life to focus on climate change writing and campaigning. Tim drops into the studio and we discuss why, and talk about his new book (his second follow up to the highly influential The Weather Makers): Sunlight and Seaweed: An Argument For How To Feed, Power, and Clean Up The World.

Greening the Apocalypse

    Coincidentally, I was looking into kelp farming recently.

    Tim Flannery seems to be more interested in selling books printed on dead trees than anything else, so I think it’s safe to ignore him and go straight to the source.

    The guy who is credited with pioneering this idea, at least here in the states (they’ve been doing this sort of thing in Asia for decades), is Bren Smith and his oyster farm over in New Haven, CT.

    What is easily overlooked is the amount of nutrients needed to grow a kelp forest. There are indeed a few places in the world where abundant nutrients are carried to the surface for free by deep ocean currents.

    The mid-ocean is not one of them.

    And now that the wealthy industrialized countries have succeeded in strip mining the world’s oceans, well, something tells me there will be a lot fewer nutrients to go around for anybody.

    However, don’t try and tell that to the greens, they are to busy freaking out about the impending apocalypse and what in the world are they going to DO about it.

    Oh well, at least the jellyfish are doing well. Bon appetit.

    There’s an Unprecedented Wildfire in Greenland. That’s Bad News for the Arctic.
    Across the entire Arctic, forests are burning at a rate unseen in at least 10,000 years.

    Thirty Years After the Montreal Protocol, Solving the Ozone Problem Remains Elusive

    Despite a ban on chemicals like chlorofluorocarbons, the ozone hole over Antarctica remains nearly as large as it did when the Montreal Protocol was signed in 1987. Scientists now warn of new threats to the ozone layer, including widespread use of ozone-eating chemicals not covered by the treaty.

    “Here we argue that this suggests that the typical technological species becomes extinct soon after attaining a modern technology and that this event results in the extinction of the planet’s global biosphere.”

    aptard, would you still tarding hard if it’s argued that white extinction is due to jews? would you support tard extremist preachers?

    relax, their extinction is not tied to our survival. i’m not arguing we kill them, ok

    there’s a school of thought that says earthw orms are beneficial to plants. really? where are these worms so we can feed ducks? they love them.

    maybe it’s the oxygen that plant needs and the worms can go extinct?

    Here are just a few of the dozens of reasons why seaweed can’t make a dent in energy supplies:

    negative return on investment like corn ethanol
    much of it is already spoken for as animal feed, food and additives, fertilizer, cosmetics
    as a monocrop it would be just as vulnerable to pests as land crops and pesticides can’t be used to protect them
    the most desirable kelp is the massive brown variety which only grows in water 43 to 57 F where there are rocks to attach to and protected from storm waves and strong currents
    Like land biomass, it doesn’t scale up (Friedemann 2007). A U.S. Department of Energy study states that if we could increase world-wide production of seaweed 10.5 fold, we could produce 1% of United States domestic gasoline supply (Roesijadi)
