Human activities increase atmospheric concentrations of greenhouse gases – which tend to warm the atmosphere – and still in some aerosol regions – that tend to cool the atmosphere. These combined changes in greenhouse gases and aerosols are expected to result in regional and global changes in climate and climate parameters such as temperature, precipitation, soil moisture and sea level. Based on the range of climate sensitivities reported by the IPCC Working Group I for increasing greenhouse gas concentrations and plausible emission zones (IPCC 1992), experienced climate models, taking into account greenhouse gases and aerosols, an increase in the average global surface temperature of about 1-3.5oC by 2100 and a rise in sea level of about 15 to 95 cm. The reliability of regional forecasts remains low and the extent to which climate variability may change is uncertain. However, potentially serious changes have been observed, including an increase in extreme high temperature events, floods and droughts in some areas, with the following consequences of fires, outbreaks of pests and the composition, structure and functioning of the ecosystem, including primary productivity (IPCC, 1995). 2004 – COP 10 was held in Buenos Aires, Argentina. The parties began to discuss accommodation options. The parties “have made many decisions and conclusions on technology development and transfer issues and have adopted conclusions; Land use, land use change and forestry; UNFCCC`s financial mechanism; national communication of [developed] countries; Capacity building Accommodation and response and UnFCCC Article 6 (Education, Training and Public Awareness) on adaptation and mitigation issues, the needs of least developed countries (LDCs) and future strategies to combat climate change. Because climate change is fuelling rising temperatures and extreme weather events, it is endangering our air, water and food; Widespread diseases and endangers our homes and security. We are facing a growing public health crisis. The last annual UN climate change conference, COP25, was held in Madrid, Spain, in December 2019. COP25 is expected to be a springboard for the 2020 climate change conference, at which countries are expected to set new NPPs and funding commitments (however, the COP26 conference, to be held in November 2020, was rescheduled in November 2021 due to the COVID 19 pandemic). Under this agreement, China, for example, will be able to increase these emissions by an incredible number of years – 13 years.
They can do whatever they want for 13 years. We don`t. India is conditional on its participation in receiving billions and billions of dollars in foreign aid from industrialized countries. There are many other examples. But at the end of the day, the Paris agreement is very unfair, at the highest level, to the United States. It is rare that there is consensus among almost all nations on a single subject. But with the Paris agreement, world leaders agreed that climate change was driven by human behaviour, that it was a threat to the environment and to humanity as a whole, and that global action was needed to stop it. In addition, a clear framework has been put in place for all countries to make commitments to reduce emissions and strengthen these measures over time.
