Concentrations of carbon dioxide in the atmosphere are higher than at any time in human history, and nine of the warmest years have occurred since 2005.
Even with the progress made in introducing alternatives to fossil fuels, gaining energy efficiencies and proposed carbon regulations around the world, avoiding catastrophic impacts on our coastal infrastructure, biodiversity, food, energy and water resources will require more. In particular, many climate researchers like myself believe government needs to advance technology that will actually suck carbon dioxide out of the air and put it away for very long periods.
