"London — Technologies to reflect some of the sun's rays away from Earth, as a way to cool future runaway climate change, are moving closer to becoming a reality, and rules are needed now to govern them, scientists and other experts said on Monday."

"The chapter discusses sources of uncertainties in climate models and their possible impacts on the model results. The three criteria “adequacy”, “consistency” and “representativeness” are suggested for a comprehensive assessment of the quality of climate models. The fit to data determines the model’s representativeness. For many climate variables, such as precipitation, cloudiness and the climate sensitivity, this has not significantly improved from the second-to-last to the last assessment report of the Intergovernmental Panel on Climate Change (IPCC)."

"THE WORLD must urgently agree controls on solar geoengineering to weigh up its possible risks and benefits before deciding to go ahead, one expert says."

"In the final analysis, there should be a global moratorium on large-scale geo-engineering intervention in the world’s climate until everything is in place: rules and regulations to be formulated must be accepted at the global level while sufficient research and pilot experiments must be carried out. A global research pool must also be formed. Recent findings regarding geo-engineering must be transparent and open."
