Turning up the heat: how the diplomatic push for 1.5℃ unfolded in Paris
The inclusion of a 1.5°C temperature limit in the new Paris climate agreement was a major victory for the poorest countries and island nations who came to Paris saying they wanted the world to act.
By placing the 1.5°C limit alongside the legally binding goal to hold global temperatures “well below 2°C above pre-industrial levels”, the deal offered hope to the many who had begun to despair about the prospects of an ambitious enough global climate agreement ever being reached.
1.5°C temperature limit - key facts
Since 2009 Small Island Developing States and Least Developed Countries have been calling for limiting global temperature rise to below 1.5°C above pre-industrial levels. This page is an information pool for material around the 1.5°C temperature goal.
For most vulnerable, 1.5°C warming limit is critical: above it, climate impacts rise rapidly
A new study analyses the differences in impacts the world would face at 1.5°C and 2°C in a comprehensive and comparable way for the first time. It finds that the increases in impacts between 1.5°C and 2°C are large, significant and pronounced for regions with limited adaptive capacity and high exposure.
What we do
Our activities include: synthesising and advancing scientific knowledge in the area of climate change science, policy and impacts; providing science and policy support to the Least Developed Countries and Small Island Developing States in international climate negotiations, and tracking and analysing the effectiveness of national climate policies globally with the Climate Action Tracker
A multidisciplinary and culturally diverse team composed of experts in climate science and impacts, including authors of the IPCC, experts in climate finance, adaptation, climate negotiation, mitigation policies and climate policy analysis.
Synthesise and advance scientific knowledge in the area of climate change and on this basis provide support and capacity building to stakeholders. By linking scientific and policy analysis, we provide state-of-the-art solutions to global and national climate change policy challenges.
Supporting science-based policy to prevent dangerous climate change, enabling sustainable development
