Governments are still much too slow in implementing important measures that are needed to reach vital targets to reduce greenhouse gas emissions, a group of nuclear experts has said.The European Nuclear Society’s High Scientific Council said in a position paper it was concerned to see that commitments taken by countries as part of the 2015 Paris Agreement will lead to a 3C increase in global temperatures.The Paris Agreement calls for the increase in the global average temperature to be kept well below 2C above pre-industrial levels.
