UN Intergovernmental Panel on Climate Change. Global warming of 1.5°C. An IPCC Special Report on the impacts of global warming of 1.5°C above pre-industrial levels and related global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty. World Meteorological Organization. Geneva. 2018.
Key findings:
-
Global warming of 2 degrees Celsius above pre-industrial levels poses greater risks than previously believed. These risks can be substantially reduced by limiting warming to 1.5 degrees
-
Limiting warming to 1.5 degrees C requires dramatic emission reductions by 2030 and carbon neutrality by around 2050. This would entail unprecedented transformations of energy, land, urban, and industrial systems, including measures to achieve “negative emissions” by removing carbon from the atmosphere.
- Adaptation efforts are currently insufficient to prevent losses associated with 1.5 degrees C warming, but can be significantly increased to reduce the negative consequences of climate change.
