• •More and more climate scientists are supporting experiments to cool Earth by altering the stratosphere or the ocean
• •Scientists want to run controlled experiments to see if the methods are productive, to test consequences and perhaps to show objectively that the approaches can cause serious problems
• •Some scientists say the term “geoengineering” should refer only to techniques that alter Earth systems

Scientists are increasingly open to experimenting with geoengineering techniques to cool Earth, such as releasing sulfur dioxide into the stratosphere or spreading iron across the ocean. These techniques are controversial, but some researchers argue that they are necessary to avoid the worst effects of climate change.
