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. There are also serious legal and constitutional issues. Foreign leaders in Europe, Asia and around the world should have no more to say about the U.S. economy than our own citizens and their elected representatives. That is why our withdrawal from the agreement is a reaffirmation of American sovereignty. (Applause) Our constitution is unique among all the nations of the world, and it is my supreme commitment and the greatest honor to protect them. And I will. The alliance of small island states and least developed countries, whose economies and livelihoods are most affected by the negative effects of climate change, has taken the initiative to address losses and damage as a particular theme of the Paris Agreement.  However, developed countries were concerned that looking at the issue as a separate issue that goes beyond adaptation would create additional climate funding or imply legal responsibility for catastrophic climate events.
The UN report warns that the terrible effects of climate change will come sooner than expected. This is why we need to follow the report`s advice and why every tonne of emissions reduction can make a difference. The countries most affected by the effects of climate change will be low-lying nations, particularly vulnerable to sea level rise, and developing countries that do not have the resources to adapt to changes in temperature and precipitation. But prosperous nations like the United States are also increasingly vulnerable. In fact, millions of Americans – especially children, the elderly and the poor – are already suffering from the wrath of climate change. The Kyoto Protocol, a pioneering environmental treaty adopted at COP3 in Japan in 1997, is the first time nations have agreed on country-by-country emission reduction targets. The protocol, which only came into force in 2005, set binding emission reduction targets only for industrialized countries, based on the fact that they are responsible for most of the world`s high greenhouse gas emissions. The United States first signed the agreement, but never ratified it; President George W.
