Essay On Paris Agreement On Climate Change

President Obama was able to formally enshrine the United States in the agreement through executive measures because he did not impose new legal obligations on the country. The United States already has a number of instruments on the books, under laws already passed by Congress to reduce carbon pollution. The country officially joined the agreement in September 2016, after submitting its request for participation. The Paris Agreement was only able to enter into force after the formal accession of at least 55 nations representing at least 55% of global emissions. This happened on October 5, 2016 and the agreement came into force 30 days later, on November 4, 2016. Now, that future could be in jeopardy, as President Donald Trump prepares to pull the United States out of the agreement – a step he can only legally take after the next presidential election – as part of a larger effort to dismantle decades of U.S. environmental policy. Fortunately, instead of giving up the fight, city, state, economy and citizens across the country and around the world are stepping up efforts to advance the clean energy advances needed to achieve the goals of the agreement and curb dangerous climate change, with or without the Trump administration. The IPCC notes that climate change is limited only by a „substantial and sustainable reduction in greenhouse gas emissions.“ While the benefits of presenting a single global temperature threshold as a dangerous climate change can be discussed, the general scientific view is that an increase in global temperatures of more than 2 degrees Celsius would be an unacceptable risk – potentially leading to mass extinctions, more severe droughts and hurricanes, and an arid region. While it is not clear that global warming will cause „sudden and irreversible changes“ in Earth`s systems, the risk of exceeding the threshold only increases if temperatures rise. While the Paris Agreement ultimately aims to limit global temperature increase to 1.5 degrees Celsius this century, many studies evaluating the voluntary commitments of some countries in Paris show that the cumulative effect of these emission reductions will not be significant enough to keep temperatures below that ceiling. Indeed, the targets set by the target countries should limit the future increase in temperature between 2.7 and 3.7 degrees Celsius.

At the same time, recent assessments of countries` developments in the framework of their climate targets in Paris indicate that some countries are already not meeting their commitments. The American people believe in climate change – and they are determined to address it. In 1992, President George H.W. Bush joined 107 other heads of state at the Rio Earth Summit in Brazil to adopt a series of environmental agreements, including the UNFCCC framework, which is still in force today. The international treaty aims to prevent dangerous human intervention in the planet`s climate systems in the long term.
