Annual Review of Climate change-- from Paris to Marrakech
Article | Global change Research Information Center?

Editor's note
On December 12, 2015, the 197 parties to the United Nations Framework Convention on Climate change (UNFCCC) unanimously agreed to adopt the Paris Agreement at the Paris Climate change Conference, promising to strengthen the response to the threat of global climate change, ensure that the global average temperature rise is less than 2 degrees Celsius above pre-industrial levels, and strive to limit the warming to less than 1.5 degrees Celsius.
Over the past year, the international community has formulated more ambitious policy actions and programmes to address climate change, made further progress in climate change science and technology, and actively promoted the ratification process of the Paris Agreement. On November 4, 2016, the Paris Agreement formally entered into force.
This paper collates the global climate change policy actions and scientific and technological progress in the past year after the Paris Climate Conference, and combs the milestones in the ratification process of the Paris Agreement and China's policy actions for reference.
Global climate change policies and actions
In order to deal with climate change, the international community has formulated more ambitious climate change action plans and programmes. At the level of international organizations, the United Nations has formulated an action plan to deal with El Ni ñ o, the World Bank has issued an action plan on global climate change, the International Renewable Energy Agency has issued an action plan for the development of renewable energy, the G7 summit issued a declaration on climate change, energy and resource use commitments, the World Resources Institute proposed key elements to promote the Paris Agreement, and international attention to the carbon pricing mechanism is on the rise. At the national or regional level, North American countries focus on energy strategies and emission reduction policies. The United States has issued an offshore wind power strategy, an "innovation mission" development plan, signed a memo on climate change and energy cooperation, and formulated relevant standards for reducing greenhouse gas emissions. Canada has also issued a provincial five-year climate action plan. The EU has launched the second phase of the Global change Alliance and funded projects related to climate change adaptation.

Climate change facts
The past year has become an unprecedented year in the history of climate change, with temperature, carbon dioxide concentration, sea level, sea ice and other indicators setting records or becoming milestones. Much attention has been paid to the impact of sea ice change and ocean warming on climate change, and studies on stagnation of global warming, attribution of climate change and ancient floods have also triggered heated discussions.

Impact of climate change
Over the past year, climate change has affected many aspects of the world, including affecting water resources systems such as rivers and freshwater, endangering coastal areas and marine ecosystems, in addition to the impact on natural systems, climate change also increases risks to human health and has a negative impact on world heritage and tourism.

Climate change adaptation
In order to effectively deal with the risks brought by climate change, international organizations actively make suggestions for climate change adaptation, put forward countermeasures for food security in the context of climate change, and put forward reasonable water resources management suggestions for the pressure of water shortage. Scientists have also actively explored ways to adapt to climate change and discovered new technologies for sequestration of carbon dioxide, but also pointed out that there are risks in the exploration of climate geological engineering technology. Global efforts to adapt to climate change have been increasing over the past five years, with more than 25 billion climate funds approved.

Climate change mitigation
Global greenhouse gas emissions continued to grow in 2015, but at a slower pace, and global carbon emissions were decoupled from economic growth. The contribution of renewable energy plays an important role, and the global renewable energy develops rapidly and achieves remarkable results. A variety of potential ways to reduce emissions are being explored continuously. For China, the peak of coal consumption is likely to come ahead of time.
Financial trends of global climate change
The amount of global climate financing has reached a new high, and there is still a large gap in climate investment. According to the Climate Policy Center, global investment in climate initiatives such as renewable energy and adaptation reached US $391 billion in 2014, an increase of 18 per cent over 2013 and the largest year in history. East Asia and the Pacific remain the largest region for climate financing, with China alone accounting for 22 per cent of total climate financing. In 2015, the climate financing of six multilateral development banks reached US $25 billion, accounting for 31.04 per cent of the total global climate financing. Climate investment fund plays a significant role in solving the investment demand, but there is still a large investment gap in the future.
The ratification process of the Paris Agreement
On October 5, UN Secretary-General Ban Ki-moon announced that the Paris Agreement on climate change would enter into force on November 4, 2016. Less than a year after its adoption, the Paris Agreement is about to enter into force since its enactment in December 2015, making it one of the fastest international treaties in history. The following are milestones in the ratification of the Paris Agreement:
one
15 countries approved at the first signing ceremony-sending a positive signal
two
Sino-US Joint ratification-accelerating the entry into force of the Agreement as soon as possible
three
Approved by 31 countries at the deposit ceremony-one of the conditions for entry into force
four
Indian ratification-bringing the final conditions for entry into force closer
five
EU "rapid" ratification-all conditions for formal entry into force are met
As of November 4, a total of 97 parties around the world have ratified the Paris Agreement, accounting for more than 69.22% of global carbon emissions. ?
