Adaptation issues required increased attention during the formation of the Paris Agreement. Long-term collective adjustment targets are included in the agreement and countries are accountable for their adaptation measures, making adaptation a parallel element of the agreement with reduction.  Adjustment targets focus on improving adaptive capacity, increasing resilience and limiting vulnerability.  Since Trump`s announcement, US envoys have continued to participate in UN climate negotiations, as planned, in order to consolidate the details of the agreement. Meanwhile, thousands of leaders across the country have stepped in to fill the void created by the lack of federal climate leadership, reflecting the will of the overwhelming majority of Americans who support the Paris Agreement. Among city and state officials, business leaders, universities, and individuals, there has been a wave of participation in initiatives such as America`s Pledge, the U.S. Climate Alliance, We Are Still In, and the American Cities Climate Challenge. Complementary and sometimes intersecting movements aim to deepen and accelerate efforts to combat climate change at local, regional and national levels. Each of these efforts focuses on achieving the goals of the Paris Agreement, despite Trump`s attempts to steer the country in the opposite direction. (a) maintain the increase in global average temperature to well below 2 °C above pre-industrial levels and endeavour to limit the temperature increase to 1,5 °C above pre-industrial levels, while recognising that this would significantly reduce the risks and effects of climate change; In fact, research clearly shows that the cost of climate inaction far outweighs the cost of reducing carbon pollution.
A recent study suggests that if the U.S. fails to meet its Paris climate goals, it could cost the economy up to $6 trillion in the coming decades. A global failure to comply with the DND currently set out in the agreement could reduce global GDP by more than 25% by the end of the century. Meanwhile, another study estimates that achieving – or even exceeding – that the Paris targets could be very beneficial on a global scale by investing in infrastructure in clean energy and energy efficiency, to the amount of about $19 trillion. Carbon dioxide, salmon gas, and methane are gases that accumulate in the atmosphere and prevent heat from spreading from the Earth`s surface into space, resulting in what`s known as a greenhouse effect. . . .
