Expert commentary on IPCC Special Report on 1.5C Global Warming

Monday 8 October 2018

It is possible to limit warming to 1.5C, but it will be profoundly challenging & action taken in the next few years will be crucial. There are lots of synergies between reducing emissions, adapting to climate changes & with broader sustainable devt.

Professor Mark Howden from the Australian National University's Climate Change Institute is a Review Editor on the latest Special Report from the Intergovernmental Panel on Climate Change (IPCC) released today. He is also a Vice-Chair of the IPCC.

Professor Howden said the report showed at current rates of temperature increases, the world will likely reach 1.5oC  global warming by around 2040.

"At this point, there are very few practical pathways left that can keep warming to below 1.5oC  ," Professor Howden said. 

"But one of the key messages from this special report is the longer we leave taking action, the faster we'll have to reduce greenhouse gas emissions and the more it will cost including through unwanted impacts of climate change."

For the first time, the IPCC Special Report compares the risks presented by scenarios of 1.5oC  warming with 2oC warming, showing extreme weather events, heat-related morbidity and food shortages will be substantially worse at 1.5oC   than 2oC.

"It is possible to limit warming to 1.5oC, but it will be profoundly challenging and action taken in the next few years will be crucial."

"There are lots of synergies between reducing emissions, adapting to climate changes and with broader sustainable development"
