For one, Mark Serez, a meteorologist who instructs the U.S. National Ice and Ice Data Center at the University of Boulder, Colorado, wonders if they will work as intended. “If you put silica beads in a fast-moving ocean wave zone, especially from the Strait, they will be dispersed quickly,” he says.
The proposal also raises financial questions, such as who will pay the approximately -5 1-5 billion (m 800m to b 4bn) for the production, shipping, testing and distribution of the required silica beads in Fram Strait. It may be a teary-eyed picture, but it starts at a little over the estimated 60 460bn (b 360bn) spent by the United States. Excessive weather and climate catastrophe between 2017 and 2019 alone, Field notes.
Are researchers Learn about the potential for other geo-engineering aches and pains to prevent melting Arctic, but no one comes without problems. One, for example, would have to build millions Air-powered equipment to carry water from deep to the surface of ice Bitz says to create dense layers of ice – energy that is constant and may not be very efficient. He and Ceres see such an approach as a solution to the gap that prevents climate change, in which they treat only one symptom – silica dust, in the case of temperature – when they do nothing about the root causes. If the field strategy works as intended, “it’s great,” says Bitz, “but I Know It will not work to remove CO2 first. ”
Field agrees that geoengineering is in no way a substitute for reducing carbon emissions. Instead, she sees it as an opportunity to buy the time needed for global economies to build and prevent the adverse effects of climate change. “Silica beads have” backup plans that I hoped we would never need, “she says.
