Welcome to the Anthropocene.
Decisions made today about planet-warming emissions will influence climate impacts not just for decades but for centuries and perhaps even millennia, a panel from the National Academy of Sciences warned Friday.
Given the longevity of carbon dioxide and other greenhouse gases in the atmosphere, these scientists said, these decisions effectively lock humanity in for a range of impacts, some of which can be "very severe."
"Emissions of carbon dioxide from the burning of fossil fuels have ushered in a new epoch where human activities will largely determine the evolution of Earth's climate," the scientists wrote.
"Actions taken during this century will determine whether the Anthropocene climate anomaly will be a relatively short term and minor deviation from the Holocene climate, or an extreme deviation extending over many thousands of years."
