Nayagarh,(Baghuabarta): The COP26 summit is ‘our last best hope’ to agree on implementing the Paris Agreement, which limits the rise in global temperatures and keeps the goal of 1.5 degrees Celsius alive, summit President Alok Sharma said as he formally opened the climate conference in Glasgow on Sunday. The Indian-origin Cabinet minister, who is leading the UK presidency of the 26th Conference of Parties (COP26) to the United Nations Framework Convention on Climate Change (UNFCCC) at the Scottish Event Campus (SEC), has described his role as “shepherd-in-chief” of the two-week-long summit.
