British Prime Minister David Cameron used his speech to reflect on how future generations would react to the idea that it would be “too difficult” for this generation of politicians to reach an agreement in 2015. According to the United Nations Environment Programme (UNEP), temperatures are expected to rise by 3.2oC by the end of the 21st century, based solely on the current climate commitments of the Paris Agreement. To limit the increase in global temperature to 1.5 degrees Celsius, annual emissions must be below 25 Gigaton (Gt) by 2030. With the current commitments of November 2019, emissions by 2030 will be 56 Gt CO2e, twice the environmental target. To limit the increase in global temperature to 1.5 degrees Celsius, an annual reduction in emissions of 7.6% is needed between 2020 and 2030. The four main emitters (China, the United States, the EU-27 and India) have contributed more than 55% of total emissions over the past decade, excluding emissions due to land use changes such as deforestation. China`s emissions increased by 1.6% in 2018 to a peak of 13.7 Gt CO2 equivalent. U.S. emissions account for 13% of global emissions and emissions have increased by 2.5% in 2018. EU emissions, which account for 8.5% of global emissions, have fallen by 1% per year over the past decade. Emissions fell by 1.3% in 2018. In 2018, 7% of India`s global emissions increased by 5.5%, but its per capita emissions are one of the lowest in the G20.
 b) increase the capacity to adapt to the negative effects of climate change and promote climate resilience and the development of low greenhouse gas emissions in a way that does not endanger food production; On October 5, 2016, when the agreement reached enough signatures to cross the threshold, U.S. President Barack Obama said, “Even if we achieve all the goals… we will only get to part of where we need to go. He also said that “this agreement will help delay or avoid some of the worst consequences of climate change.” It will help other nations reduce their emissions over time and set bolder goals as technology progresses, all under a strong transparency system that will allow each nation to assess the progress of all other nations.    The Paris Agreement establishes a global framework to prevent dangerous climate change by limiting global warming to a level well below 2 degrees Celsius and by making efforts to limit it to 1.5 degrees Celsius. It also aims to strengthen countries` capacity to cope with the effects of climate change and to assist them in their efforts. In July 2020, the World Meteorological Organization (WMO) announced that it would estimate a 20% probability of global warming relative to pre-industrial values of more than 1.5 degrees Celsius in at least one year between 2020 and 2024, with 1.5 degrees Celsius as a key threshold under the Paris Agreement.   The agreement recognizes the role of non-partisan stakeholders in the fight against climate change, including cities, other sub-national authorities, civil society, the private sector and others. A study published in 2018 shows a threshold where temperatures could rise to 4 or 5 degrees (ambiguous expression, continuity would be “4-5 degrees Celsius”) compared to pre-industrial levels, compared to pre-industrial levels, thanks to returns of self-amplitude in the climate system, indicating that this threshold is below the 2-degree temperature target agreed in the Paris climate agreement. Study author Katherine Richardson points out: “We find that in its history, the Earth has never had a nearly stable state, warmer than that of pre-industrial, and suggests that there is a significant risk that the system itself, because of all these other processes, will want to continue warming, even if we stop emissions.
