In the context of this debate, important climate agreements have developed in the way they aim to reduce emissions. The Kyoto Protocol only required developed countries to reduce their emissions, while the Paris Agreement recognized that climate change was a common problem and called on all countries to set emission targets. Carbon dioxide, nitrous oxide and methane are gases that accumulate in the atmosphere and prevent heat from radiating from the Earth`s surface into space, creating the so-called greenhouse effect. According to the Intergovernmental Panel on Climate Change (IPCC), the leading international scientific body working on the issue, the concentration of these heat storage gases has increased dramatically since pre-industrial times to levels not seen in at least 800,000 years. Carbon dioxide (the main cause of climate change) has increased by 40%, nitrous oxide by 20% and methane by 150% since 1750 – mainly from the combustion of dirty fossil fuels. The IPCC says it is “extremely likely” that these emissions are mainly responsible for the rise in global temperatures since the 1950s. At the same time, deforestation and forest degradation have also contributed to their fair share of global carbon emissions. So what happens when the two come together to face a potentially existential threat to global civilization? When world leaders celebrated a historic climate agreement in Paris in December 2015, the Eiffel Tower and Arc de Triomphe were illuminated with green spotlights and the message “Paris Agreement is done!” (the Paris Agreement is ready!). Now, five turbulent years later, a new slogan could be “work in progress.” It is rare that there is consensus among almost all nations on a single issue.

But with the Paris Agreement, world leaders agreed that climate change is driven by human behavior, that it poses a threat to the environment and all of humanity, and that global action is needed to stop it. A clear framework has also been put in place for all countries to make commitments to reduce emissions and strengthen these measures over time. Here are some key reasons why the deal is so important: Since Trump`s announcement, U.S. envoys have continued to participate in UN climate negotiations — as mandated — to solidify the details of the deal. 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 vast majority of Americans who support the Paris Agreement. Among city and state leaders, 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 overlapping movements aim to deepen and accelerate efforts to combat climate change at local, regional and national levels. Each of these efforts is focused on the U.S.

working toward the goals of the Paris Agreement, despite Trump`s attempts to steer the country in the opposite direction. Following a campaign promise, Trump – a climate denier who claimed climate change was a “hoax” committed by China – announced in June 2017 his intention to withdraw the United States from the Paris Agreement. But despite the president`s statement from the rose garden that “we`re going out,” it`s not that easy. The withdrawal process requires the agreement to be in force for three years before a country can formally announce its intention to leave. Then he will have to wait a year before leaving the pact. This means that the United States could officially leave on November 4, 2020 at the earliest, one day after the presidential election. Even a formal withdrawal would not necessarily be permanent, experts say; A future president could return to the board in just one month. Paris has been successful as a new type of climate agreement. The regulation can help make it a strong and sustainable regime, provided it remains faithful to the Paris Agreement itself.
