The Earth is locked on an “irreversible” course of climatic disruption from the buildup of greenhouse gases in the atmosphere, and the impacts will only worsen unless nations agree to dramatic cuts in pollution, an international panel of climate scientists warned Sunday.
The planet faces a future of extreme weather, rising sea levels and melting polar ice from soaring levels of carbon dioxide and other gases, the U.N. panel said. Only an unprecedented global effort to slash emissions within a relatively short time period will prevent temperatures from crossing a threshold that scientists say could trigger far more dangerous disruptions, the panel warned.
“Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts,” concluded the report by the United Nations’ Intergovernmental Panel on Climate Change (IPCC), which draws on contributions from thousands of scientists from around the world.
