Burying the greenhouse gas carbon dioxide, a byproduct of burning fossil fuels, has been mooted as one geoengineering approach to ameliorating climate change. To be effective, trapping the gas in geological deposits would be the for the very long term, thousands of years. Now, a team in Brazil, writing in the International Journal of Global Warming has reviewed the risk assessments for this technology and suggests a lack of knowledge means we should be cautious of turning to this method rather than finding sustainable ways to reduce emissions at their source.
