One of the most important architectural concepts of Cancun`s 2oC target, which has been transferred to the long-term temperature target of Paris, is to “keep warming” below a certain level. The term “Hold below” is significantly stronger than a return to a certain degree of warming up to a certain time (up to 2100 (of a higher implied level). During the negotiations on this warming target, formulations such as the return to 2oC by 2100 were proposed and rejected. In reviewing a series of emission pathways that meet a long-term temperature target, a requirement to remain below a certain level of warming requires larger and faster emission reductions than a temperature target requiring, for example, a return to a certain degree of warming by the year 2100. This has a concrete impact on policies – and emissions trajectories – and, as a result, the Climate Action Tracker has made sure to use channels that are fully in line with the objectives. The Climate Action Tracker used these methods as a benchmark to reduce emissions in line with cancun`s target of 2oC and as a basis for assessing the adequacy of individual countries` efforts. The authors of the agreement have set a withdrawal period that President Trump must follow – which prevents him from irreparably harming our climate. The Paris Agreement (the Paris Agreement) [3] is an agreement within the framework of the United Nations Framework Convention on Climate Change (UNFCCC) that deals with the reduction, adaptation and financing of greenhouse gas emissions and was signed in 2016. The language of the agreement was negotiated by representatives of 196 States Parties at the 21st UNFCCC Conference of parties held at Le Bourget, near Paris, France, and agreed on 12 December 2015. [4] [5] Since February 2020, all 196 UNFCCC members have signed the agreement and 189 have left.

[1] Of the seven countries that are not parties to the law, Iran and Turkey are the only major emitters. The origin of the 1.5oC Paris Agreement stems from the concern of vulnerable countries about the negative consequences of a warming of 2oC. In 2014, the UNFCCC established a process to determine whether Cancun`s long-term goal of keeping warming below 2 degrees Celsius is sufficient to avoid dangerous climate change and to consider “strengthening the long-term global goal based on the best available scientific knowledge, including an average global temperature increase of 1.5 degrees Celsius.” This process ended in 2015 with the final report of its scientific arm (Structured Expert Dialogue), which concluded that the use of the global warming limit of 2oC as a “protection barrier” was not safe and that governments should instead aim for 1.5 degrees Celsius.
