Prime Minister, Tuilaepa Sa’ilele Malielegaoi, has urged world leaders attending the United Nations Climate Change Summit in New York – including President Barack Obama – that the time for waiting is over.Addressing the Summit on Wednesday, Tuilaepa said global efforts to address the root causes of climate change are lacking.This is what he said:Samoa was proud to be amongst the 134 co-sponsors of the Peace and Security in the Africa ebola resolution last Thursday, the highest number of co-sponsors ever for a decision adopted by the Security Council.The UN General Assembly followed with the same determination the next day and unanimously approved the proposal to set up an international emergency response mission for ebola.The decisiveness and unanimity of our collective response was both unprecedented and admirable. Important decisions were taken urgently and implemented immediately, a positive reminder that where there is a will and unity of purpose, there is always a way, and when every member state irrespective of economic or political status steps forward to lend a supportive hand, the chances of success are invariably high.Last week’s events were in sharp contrast to the way some member states have responded over the years to the global efforts to address the root causes of climate change.Our Pacific countries had advocated, and continue to make the case that climate change has significant security implications. Sadly, some amongst our global community had been dismissive and remain unconvinced. Others through their actions had been indifferent and unsympathetic.Samoa was proud to be amongst the 134 co-sponsors of the Peace and Security in the Africa ebola resolution last Thursday, the highest number of co-sponsors ever for a decision adopted by the Security Council.The UN General Assembly followed with the same determination the next day and unanimously approved the proposal to set up an international emergency response mission for ebola.The decisiveness and unanimity of our collective response was both unprecedented and admirable.

Sadly, some amongst our global community had been dismissive and remain unconvinced. Others through their actions had been indifferent and unsympathetic.And many more had made promises that were not followed through with firm commitments and concrete action.That is why I want to acknowledge our Secretary-General’s passionate advocacy for an ambitious Paris climate agreement next year.
