They say a global authority is needed to protect the international community from unintended consequences.
According to the Guardian:
“Met Office researchers have called for global oversight of the radical schemes after studies showed they could have huge and unintended impacts on some of the world’s most vulnerable people.”
The dangers arose in projects that cooled the planet unevenly. In some cases these caused devastating droughts across Africa; in others they increased rainfall in the region but left huge areas of Brazil parched.
“The massive complexities associated with geoengineering, and the potential for winners and losers, means that some form of global governance is essential,” said Jim Haywood.”
This is not the first time scientists have spoken out about the dangers of Geo-engineering. Recently Harvard University climate scientist David Keith and UCLA environmental law expert Edward Parson wrote in the journal Nature about the need for guidelines to guide research on the controversial technology. Keith has spoken on the benefits of geo-engineering in the past but now appears to be warning of the dangers.
Keith and Parson believe that governments should begin “informal” planning to oversee small-scale field experiments that they say could help scientists understand how the atmosphere would respond to geoengineering. They are also calling for a moratorium on large scale experiments.
One of the many dangers of manipulating the weather are the loss of blue skies. According to a report by the New Scientist, Ben Kravitz of the Carnegie Institution for Science has shown that releasing sulphate aerosols high in the atmosphere would scatter sunlight into the atmosphere. He says this could decrease the amount of sunlight that hits the ground by 20% and make the sky appear more hazy.
Geo-engineering is the science of manipulating the climate for the state purpose of fighting mad made climate change.
