National Science Academies on Climate Change
The scientific academies of 13 countries on Tuesday urged the world to act more forcefully to limit the threat posed by human-driven global warming.
In a joint statement, the academies of the Group of 8 industrialized countries — Britain, Canada, France, Germany, Italy, Japan, Russia and the United States — and of Brazil, China, India, Mexico and South Africa called on the industrialized countries to lead a “transition to a low-carbon society” and aggressively move to limit impacts from changes in climate that are already under way and impossible to stop.
The statement, posted by the National Academy of Sciences in the United States, urged the Group of 8 countries to move beyond last year’s pledge to consider halving global emissions of greenhouse gases by 2050 and “make maximum efforts” to reach this target.
The academies recommended speeding the adoption of new energy technologies and encouraging changes in behavior that curb energy use and greenhouse-gas emissions. They also urged investing more to improve solar and nuclear energy technologies and in projects to capture and permanently store carbon dioxide produced by power plants. The academies also said it was necessary to study artificial “geoengineering” methods for stabilizing climate, as well as large-scale reforestation.
