Science Assessment
and Analysis

Climate science is highly complex and the policy implications are not always clear. We make the latest climate science easily accessible for stakeholders in the international climate change arena.

We synthesise and advance scientific knowledge in the area of climate change science, policy and impacts to make it easily accessible for stakeholders in the international climate change arena. This includes conducting our own research (for example, to evaluate the uncertainties in climate science associated with potential mitigation pathways, project sea-level rise or evaluate impacts and risks at different levels of warming) as well as bringing together and communicating the findings of the available scientific literature and providing the context needed to understand their implications. Projections of future climate change are subject to uncertainty, as they depend on a range of developments that cannot be foreseen (e.g. emission pathways). Also, there remain important limitations in the understanding and the modeling of some key processes of the climate system. Much of our work therefore focused on understanding these key process and the probabilities associated with climate impact projections.

The Paris climate conference set the ambitious goal of finding ways to limit global warming to 1.5C, rather than the previous threshold of 2C. But what would be the difference? And how realistic is such a target? Article quoting research by Climate Analytics' Michiel Schaeffer and Carl-Friedrich Schleussner.  
A video explaining the impacts of climate change in the Caribbean, such as sea level rise, coastal erosion and coral bleaching, accompanied by music from the region.  
New World Bank report, produced by Climate Analytics and Potsdam Institute for Climate Impact Research (PIK), assesses climate risks in Latin American and the Caribbean, Middle East and North Africa and Europe and Central Asia  
Regular food shortages in Sub-Saharan Africa….shifting rain patterns in South Asia leaving some parts under water and others without enough water for power generation, irrigation, or drinking….degradation and loss of reefs in South East Asia resulting in reduced fish stocks and coastal communities and cities more vulnerable to increasingly violent storms….these are but a few of the likely impacts of a possible global temperature rise of 2 degrees Celsius in the next few decades that threatens to trap millions of people in poverty, according to a new scientific report released today by the World Bank Group.

This article is a first comprehensive assessment of key climate impacts for the policy relevant warming levels of 1.5 °C and 2 °C above pre-industrial levels. It finds substantial impact differences in intensity and frequency of extreme weather events, regional water availability and agricultural yields, sea-level rise and risk of coral reef loss. The increase in climate impacts is particularly pronounced in tropical and sub-tropical regions.
