A group of scientists warns that governments have consistently failed to address the root cause of climate change and that several climate tipping points are now imminent
Of 31"vital signs" - key metrics of planetary health that include greenhouse gas emissions, glacier thickness, sea-ice extent and deforestation - scientists have found that 18 hit record highs or lows.
The researchers, part of a group of more than 14,000 scientists who have signed on to an initiative declaring a worldwide climate emergency, said on Wednesday that governments had consistently failed to address the root cause of climate change: "the overexploitation of the Earth". Greenland and Antarctica both recently showed all-time low levels of ice mass, and glaciers are melting 31 percent faster than they did just 15 years ago, the authors said.
Tim Lenton, director of the University of Exeter's Global Systems Institute and study co-author, said the recent record-breaking heatwave in the Western United States and Canada showed that the climate had already begun to "behave in shocking, unexpected ways".
