Pacific islanders are running out of time. If global emissions are not drastically reduced, thousands of low-lying atolls may become uninhabitable within decades. And the biggest threat doesn’t actually come from losing land to rising seas. Small island states in the Pacific are responsible for only 0.03 percent of the world’s carbon dioxide emissions, and

As it looks increasingly unlikely we’re going to meet our climate mitigation targets, scientists have been investigating more and more extreme solutions, such as geoengineering. Examples include spraying huge amounts of sunlight-reflecting particles into the atmosphere, or dumping trillions of tons of fake snow onto glaciers to stabilise them. These ideas are untested, incredibly risky,

Living and working in space requires human perseverance. Future missions will focus on exploration at greater distances from Earth; to the Moon and then to Mars. These missions will mean humans will stay in space for extended durations. To ensure that these goals are achieved, NASA’s astronauts must be able to perform at peak productivity
