United Nations Framework Convention on Climate Change <=SEP=> The United Nations Framework Convention on Climate Change ( UNFCCC ) is an international environmental treaty adopted on May 9 , 1992 and opened for signature at the Earth Summit in Rio de Janeiro from 3 to 14 June 1992 . It then entered into force on 21 March 1994 , after a sufficient number of countries had ratified it . The UNFCCC objective is to `` stabilize greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic interference with the climate system '' . The framework sets no binding limits on greenhouse gas emissions for individual countries and contains no enforcement mechanisms . Instead , the framework outlines how specific international treaties ( called `` protocols '' or `` Agreements '' ) may be negotiated to specify further action towards the objective of the UNFCCC .   Initially an Intergovernmental Negotiating Committee ( INC ) produced the text of the Framework Convention during its meeting in New York from 30 April to 9 May 1992 . The UNFCCC was adopted on 9 May 1992 , and opened for signature on 4 June 1992 . The UNFCCC has 197 parties as of December 2015 . The convention enjoys broad legitimacy , largely due to its nearly universal membership .   The parties to the convention have met annually from 1995 in Conferences of the Parties ( COP ) to assess progress in dealing with climate change . In 1997 , the Kyoto Protocol was concluded and established legally binding obligations for developed countries to reduce their greenhouse gas emissions in the period 2008-2012 . The 2010 Cancún agreements state that future global warming should be limited to below 2.0 ° C ( 3.6 ° F ) relative to the pre-industrial level . The Protocol was amended in 2012 to encompass the period 2013-2020 in the Doha Amendment , which - as of December 2015 - had not entered into force . In 2015 the Paris Agreement was adopted , governing emission reductions from 2020 on through commitments of countries in ambitious Nationally Determined Contributions . The Paris Agreement entered into force on November 4th , 2016 .   One of the first tasks set by the UNFCCC was for signatory nations to establish national greenhouse gas inventories of greenhouse gas ( GHG ) emissions and removals , which were used to create the 1990 benchmark levels for accession of Annex I countries to the Kyoto Protocol and for the commitment of those countries to GHG reductions . Updated inventories must be submitted annually by Annex I countries .   The UNFCCC is also the name of the United Nations Secretariat charged with supporting the operation of the Convention , with offices in Haus Carstanjen , and the UN Campus ( known as Langer Eugen ) Bonn , Germany . From 2010 to 2016 the head of the secretariat was Christiana Figueres . In July 2016 , Patricia Espinosa from Mexico succeeded Figueres . The Secretariat , augmented through the parallel efforts of the Intergovernmental Panel on Climate Change ( IPCC ) , aims to gain consensus through meetings and the discussion of various strategies .

Paris Agreement <=SEP=> The Paris Agreement ( Accord de Paris ) is an agreement within the United Nations Framework Convention on Climate Change ( UNFCCC ) dealing with greenhouse gas emissions mitigation , adaptation and finance starting in the year 2020 . The language of the agreement was negotiated by representatives of 195 countries at the 21st Conference of the Parties of the UNFCCC in Paris and adopted by consensus on 12 December 2015 . It was opened for signature on 22 April 2016 ( Earth Day ) at a ceremony in New York . As of May 2017 , 195 UNFCCC members have signed the treaty , 147 of which have ratified it . After several European Union states ratified the agreement in October 2016 , there were enough countries that had ratified the agreement that produce enough of the world 's greenhouse gases for the agreement to enter into force . The agreement went into effect on 4 November 2016 .   The head of the Paris Conference , France 's foreign minister Laurent Fabius , said this `` ambitious and balanced '' plan is a `` historic turning point '' in the goal of reducing global warming .   One year on , the ratification of the Paris Agreement was celebrated by the Mayor of Paris Anne Hidalgo by illuminating the Eiffel Tower and the Arc de Triomphe , Paris ' most iconic monuments , in green .

Special Report on Global Warming of 1.5 °C <=SEP=> The Special Report on Global Warming of 1.5 °C (SR15) was published by the Intergovernmental Panel on Climate Change (IPCC) on 8 October 2018. The report, approved in Incheon, South Korea, includes over 6,000 scientific references, and was prepared by 91 authors from 40 countries. In December 2015, the 2015 United Nations Climate Change Conference called for the report. The report was delivered at the United Nations' 48th session of the IPCC to "deliver the authoritative, scientific guide for governments" to deal with climate change.Its key finding is that meeting a 1.5 °C (2.7 °F) target is possible but would require "deep emissions reductions" and "rapid, far-reaching and unprecedented changes in all aspects of society." Furthermore, the report finds that "limiting global warming to 1.5 °C compared with 2 °C would reduce challenging impacts on ecosystems, human health and well-being" and that a 2 °C temperature increase would exacerbate extreme weather, rising sea levels and diminishing Arctic sea ice, coral bleaching, and loss of ecosystems, among other impacts. SR15 also has modelling that shows that, for global warming to be limited to 1.5 °C, "Global net human-caused emissions of carbon dioxide (CO2) would need to fall by about 45 percent from 2010 levels by 2030, reaching 'net zero' around 2050." The reduction of emissions by 2030 and its associated changes and challenges, including rapid decarbonisation, was a key focus on much of the reporting which was repeated through the world.

Global warming <=SEP=> Global warming , also referred to as climate change , is the observed century-scale rise in the average temperature of the Earth 's climate system and its related effects . Multiple lines of scientific evidence show that the climate system is warming . Many of the observed changes since the 1950s are unprecedented in the instrumental temperature record which extends back to the mid 19th century , and in paleoclimate proxy records over thousands of years .   In 2013 , the Intergovernmental Panel on Climate Change ( IPCC ) Fifth Assessment Report concluded that `` It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century . '' The largest human influence has been emission of greenhouse gases such as carbon dioxide , methane and nitrous oxide . Climate model projections summarized in the report indicated that during the 21st century the global surface temperature is likely to rise a further 0.3 to for their lowest emissions scenario and 2.6 to for the highest emissions scenario . These findings have been recognized by the national science academies of the major industrialized nations and are not disputed by any scientific body of national or international standing .   Future climate change and associated impacts will differ from region to region around the globe . Anticipated effects include warming global temperature , rising sea levels , changing precipitation , and expansion of deserts in the subtropics . Warming is expected to be greater over land than over the oceans and greatest in the Arctic , with the continuing retreat of glaciers , permafrost and sea ice . Other likely changes include more frequent extreme weather events including heat waves , droughts , heavy rainfall with floods and heavy snowfall ; ocean acidification ; and species extinctions due to shifting temperature regimes . Effects significant to humans include the threat to food security from decreasing crop yields and the abandonment of populated areas due to rising sea levels . Because the climate system has a large `` inertia '' and greenhouse gases will stay in the atmosphere for a long time , many of these effects will not only exist for decades or centuries , but will persist for tens of thousands of years .   Possible societal responses to global warming include mitigation by emissions reduction , adaptation to its effects , building systems resilient to its effects , and possible future climate engineering . Most countries are parties to the United Nations Framework Convention on Climate Change ( UNFCCC ) ,  whose ultimate objective is to prevent dangerous anthropogenic climate change . Parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2.0 C-change relative to pre-industrial levels , with efforts made to limit warming to 1.5 C-change .   Public reactions to global warming and concern about its effects are also increasing . A global 2015 Pew Research Center report showed a median of 54 % consider it `` a very serious problem '' . There are significant regional differences , with Americans and Chinese ( whose economies are responsible for the greatest annual CO2 emissions ) among the least concerned .
