intends to participate in joint EU efforts to reduce emissions by 40% across the region from 1990 to 2030 levels. The specific commitment it will make to share efforts under this approach has yet to be decided; If no agreement is reached, Iceland will file a new INDC. This is INDC. It provides „another solid piece of scientifically sound evidence to justify public calls for more action from governments and businesses,“ says climate scientist Bill Hare of Berlin`s climate analysis. Hare was not involved in the report, but contributes to the Climate Action Tracker, which conducts scientific analyses of climate policy and commitments. [Note 1/6/17: When countries formally ratify the Paris Agreement, their INDCs become NDCs. To date, 146 countries and the European Union have ratified the agreement. The UN maintains separate records for NDCs and CNDs.] By analysis by the Intergovernmental Panel on Climate Change (IPCC), a carbon „budget“ based on total emissions of carbon dioxide into the atmosphere (relative to the annual emission rate) has been estimated to limit global warming to 1.5 degrees Celsius and 2.25 trillion tonnes from the 1870 period. This represents a significant increase from the initial estimates of the Paris climate agreement (out of a total of 2000 billion tonnes) to reach the global warming target of 1.5oC, a target that would be reached in 2020 for 2017 emission rates. [Clarification needed] In addition, annual CO2 emissions are estimated at 40 billion tonnes per year in 2017. The revised IPCC budget was based on the CMIP5 climate model. Estimate models using different reference years also provide other slightly adjusted estimates of a carbon „budget.“  Today, The Marrakech Partnership for Global Climate Action expands and continues Lima Paris` agenda, and the NAZCA portal has been renamed the Global Climate Action Portal.
They continued to support the implementation of the Paris Agreement by enabling cooperation between governments and cities, regions, businesses and investors who must act to combat climate change. In addition to formal intergovernmental negotiations, countries, cities and regions, businesses and civil society members around the world are taking steps to accelerate climate cooperation efforts to support the Paris Agreement as part of the Global Climate Agenda. The authors of the agreement have set a withdrawal period that President Trump must follow – which prevents him from irreparably harming our climate. 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.
