The IPCC notes that climate change is limited only by “substantial and sustainable reductions in greenhouse gas emissions.” While one can debate the benefits of using a single global temperature threshold to represent dangerous climate change, the general scientific opinion is that any 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 aqueous Arctic. Moreover, as the IPCC notes, while it remains uncertain about the extent of global warming that will trigger “abrupt and irreversible changes” in Earth`s systems, the risk of crossing the threshold only increases as temperatures rise. There is a lot of misinformation about the Paris Agreement, including the idea that it will hurt the U.S. economy. It was a series of unsused claims that Trump repeated in his 2017 rose garden speech, claiming the deal would cost the United States. The economy spans $3 trillion by 2040 and $2.7 million in jobs by 2025, making us less competitive with China and India. But as fact-checkers noted, these statistics come from a debunked March 2017 study that exaggerated the future costs of reducing emissions, underestimated advances in energy efficiency and clean energy technologies, and completely ignored the huge health and economic costs of climate change itself. In 2004, COP 10 was held in Buenos Aires, Argentina. The parties have begun to discuss adjustment options. The parties “referred to and adopted numerous decisions and conclusions on issues related to technology development and transfer; land use, land use change and forestry; the financial mechanism of the UNFCCC; the national communication of [industrialized countries]; capacity-building; accommodation and response measures; and Article 6 of the UNFCCC (Education, Training and Public Awareness), which addresses adaptation and mitigation issues, the needs of least developed countries (DDCs) and future strategies to combat climate change. On 8 December 2012, at the end of the 2012 United Nations Climate Change Conference, an agreement was reached to extend the Protocol until 2020 and set a date of 2015 for the development of a follow-up document to be implemented from 2020 (see lede for more information). [151] The outcome of the Doha talks was mixed, with small island states criticizing the entire package […].
