To contribute to the goals of the agreement, countries presented comprehensive national climate change plans (national fixed contributions, NDC). These are not yet sufficient to meet the agreed temperature targets, but the agreement points to the way forward for further measures. It will also enable the contracting parties to gradually strengthen their contributions to the fight against climate change in order to achieve the long-term objectives of the agreement. The authors of the agreement have set a withdrawal period that President Trump must follow – which prevents him from irreparably harming our climate. As mentioned above, the paris agreement`s target is 1.5 degrees Celsius outside the Cancun agreement limit of less than 2 degrees Celsius and aims to keep warming well below 2 degrees Celsius and to continue efforts to limit the temperature increase to 1.5 degrees Celsius. This figure was still well above the 2C target contained in the text of the Paris Pact and far from being the more ambitious 1.5 C target, advocated by scientists as a threshold for destructive warming in 2018. The Paris Agreement contains a series of binding measures to monitor, verify and publicly report progress towards a country`s emissions reduction targets. Improving transparency rules applies a common framework to all countries, providing housing and support to nations that are not currently able to strengthen their systems over time. Under the Paris Agreement, each country must define, plan and report regularly on its contribution to the fight against global warming.  There is no mechanism for a country to set an emission target for a specified date, but any target should go beyond the previous targets. The United States formally withdrew from the agreement the day after the 2020 presidential election, although President-elect Joe Biden said America would return to the agreement after his inauguration.
 How each country is on track to meet its obligations under the Paris Agreement can be constantly monitored online (via the Climate Action Tracker and the climate clock). Negotiators of the agreement stated that the INDCs presented at the time of the Paris conference were insufficient and found that “the estimates of aggregate greenhouse gas emissions in 2025 and 2030 resulting from the planned contributions at the national level are not covered by the least expensive scenarios of 2oC, but lead to a projected level of 55 gigatons in 2030.” and acknowledges that “much greater efforts to reduce emissions will be required to keep the increase in the average global temperature to less than 2 degrees Celsius, by reducing emissions to 40 gigatonnes or 1.5 degrees Celsius.”  [Clarification required] A study published in 2018 shows a threshold where temperatures could reach 4 or 5 degrees (ambiguous expression , continuity would be “4-5 degrees Celsius”) relative to pre-industrial levels, thanks to feedback feedbacks in the climate system, indicating that this threshold is below the 2-degree temperature target agreed in the Paris climate agreement.
