Climate pledges ‘could limit’ warming to 2°C

Previous research had suggested that pledges have only a 50pc chance of achieving 2°C target

If all current pledges to the Paris climate agreement are fulfilled global warming could be limited to just below 2°C this century, according to new research published in scientific journal Nature. Nations had agreed at Cop21 in Paris to keep global warming below 2°C this century and preferably limit it to 1.5°C. The agreement contained a ratcheting process that requires countries to update their nationally determined contributions (NDCs) every five years. Previous research had suggested that NDCs submitted to the Cop26 climate conference in Glasgow as part of the latest ratchet had at best a 50pc chance of keeping global warming to 2°C this century. Whereas research has traditionally aggreg
