On October 5, 2016, when the agreement reached enough signatures to cross the threshold, U.S. President Barack Obama said, “Even if we achieve all the goals… we will only get to part of where we need to go. He also said that “this agreement will help delay or avoid some of the worst consequences of climate change.” It will help other nations reduce their emissions over time and set bolder goals as technology progresses, all under a strong transparency system that will allow each nation to assess the progress of all other nations.   The agreement commits all countries to reduce their emissions and cooperate to adapt to the effects of climate change and calls on countries to strengthen their commitments over time. The agreement provides developed countries with a means to assist developing countries in their mitigation and adaptation efforts, while establishing a framework for monitoring and reporting transparently on developing countries` climate goals. The IPCC SR1.5 also assesses other routes that lead to higher warming levels, including pathways that keep warming below 2oC with a 66% chance and do not return to 1.5oC. The IPCC SR1.5 provides an assessment of these methods for comparing and consistency with attenuation paths compatible with 1.5oC. The IPCC SR1.5 is also very clear about the increase in climate risks between 1.5 and 2 degrees Celsius, which refers to the clause of the Paris LTTG Agreement, which recognizes that warming is well below 2 degrees Celsius and is limited to 1.5 degrees Celsius, which greatly reduces the risks and effects of climate change. To contribute to the goals of the agreement, countries presented comprehensive national climate change plans (national fixed contributions, NDC). These are not yet sufficient to meet the agreed temperature targets, but the agreement points to the way forward for further measures. Since Trump`s announcement, U.S. envoys – as well as on behalf – have continued to participate in U.N. climate negotiations to shore up the details of the agreement. Meanwhile, thousands of heads of state and government have intervened across the country to fill the void created by the lack of federal climate leadership, reflecting the will of the vast majority of Americans who support the Paris agreement.
City and state officials, business leaders, universities and individuals included a base amount to participate in initiatives such as America`s Pledge, the United States Climate Alliance, We Are Still In and the American Cities Climate Challenge. Complementary and sometimes overlapping movements aim to deepen and accelerate efforts to combat climate change at the local, regional and national levels.
