Worst-case climate change scenario could be more extreme than thought, scientists warn | The Independent
Scientists may have to recalibrate their projections of what a “worst case” climate change scenario is, as new studies take into account greater global economic growth than previously forecast.
Climate scientists forecasting how the earth’s climate will change over time examine trends in greenhouse gas emissions, which are largely dependent on how the global economy behaves. As countries get richer, the amount they consume goes up, and so too do greenhouse gas emissions.
Scientists use four scenarios called representative concentration pathways (RCPs) that attempt to depict possible futures for our planet.
