IPCC session examines pathways to 1.5°C temperature limit



17 October 2016

The Intergovernmental Panel on Climate Change (IPCC) is holding its 44th Session in Bangkok, Thailand, on 17-20 October 2016.

Among other issues, the Panel will consider the outline of the Special Report on impacts of global warming of 1.5°C above pre-industrial levels and related greenhouse gas emission pathways. This will provide a picture of the impacts of the more ambitious aspirational target reached in Paris, and explore the different routes that policymakers could take to get there.

The meeting will also consider an outline of the Methodology Report aimed at updating the 2006 IPCC Guidelines for National Greenhouse Gas Inventories.

“It’s particularly appropriate that we are meeting in Asia, where so many millions have been lifted out of poverty through development,” said IPCC Chair Hoesung Lee. “Countries in Asia are continuing to invest in energy capacity as part of this development. The IPCC’s findings make it very clear that as the countries make these plans they should avoid locking in high-carbon infrastructure that could put the 2ºC goal out of reach,” he said.

“The last few weeks have demonstrated the increasing dynamism of international policymaking on climate change. After a wave of ratifications by nations big and small, the UN Secretary-General announced two weeks ago that the Paris Agreement will enter into force on November 4 – less than 11 months after it was concluded. The next day, agreement was reached on a global carbon offsetting scheme for the aviation industry to address the growth in its CO2 emissions. And this weekend governments in Kigali amended the Montreal Protocol to phase out hydrofluorocarbons, which some say could avoid as much as half a degree of future global warming,” said Hoesung Lee.

WMO Deputy Secretary-General Elena Manaenkova recalled “the Paris Agreement, coming into force on 4 November, which has clearly underlined the importance of strengthening scientific knowledge on climate, including research, systematic observation of the climate system and early warning systems, in a manner that informs climate services and supports decision-making”.

“WMO Members and NMHSs play key role in provision of observations, risk assessments and increasingly demanded operational services in support of adaptation and mitigation. WMO is enhancing its climate portfolio for even more focused and effective services. WMO is providing annual and 5-year climate statements, GHG statements, regional climate outlooks and variety of other relevant products complementing IPCC assessments. WMO coordinate research contributes modelling products for IPCC scenarios.” she said.

WMO and the United Nations Environment Programme co-founded and co-sponsor the IPCC.
