Several countries have passed laws that set goals to stop increasing the carbon dioxide emissions that contribute to global warming, climate change and the negative environmental impacts that those trends are producing. At the same time, companies and financial institutions spotlight their efforts to help limit those emissions. But experts now say those actions will be an insufficient response to stop the dangerous extreme weather and climate volatility that has become more frequent. Fulton Schools Professor Klaus Lackner, director of ASU’s Center for Negative Carbon Emissions, and member of the Climate Crisis Advisory Group, says large amounts of existing carbon emissions must also be removed from the atmosphere if a crisis is to be averted.
