The IPCC Working Group II report covers the impacts of, and adaptation to, climate change.

Explore the topics below for information on the potential water- and food-related, economic, ecological and health impacts of climate change and details of current research taking place at Imperial.

Water security and flood risk

Changing rainfall patterns and intensity are combining with human influence to reduce water availability in India and increase flood risk in some urban areas around the world. Melting mountain glaciers are reducing water availability in parts of the Andes in South America. Read more here


Sea level rise

As well as the risks from storm surge and coastal flooding, sea level rise is also adding to the problem of salt water intrusion into drinking water supplies. Our researchers are looking at this problem in coastal Bangladesh, where it contributes to high blood pressure and pre-eclampsia. Read more on sea level rise


Food security

Carbon dioxide encourages plant growth, but the effects of rising temperatures and changing rainfall patterns will be more mixed, meaning impacts on food production will vary depending on location. Plant diseases and pests will also affect food security. Read more on food security

Changing temperatures and water availability will have major effects on particular species and entire ecosystems. We highlight some of the research on migratory species, forests and species interactions. Read more on ecosystems



Climate change will have both positive and negative effects on human health with the net impact expected to be negative globally. Our researchers work on a range of important issues including the effects of extreme heat and vector borne diseases such as malaria. Read more on health

UK impacts

Around the world there is a general move towards rain falling in shorter, heavier bursts. In addition, UK weather is dominated by the jet stream and associated storm-track over the Atlantic, but we cannot yet say if this is changing due to increasing greenhouse gases in the atmosphere. Read more on UK impacts


Supply chains

We live in an increasingly globalised world, and many countries including the UK import a significant proportion of the goods they consume. Countries cannot think about climate-related risks purely in terms of direct impacts, but must also consider their indirect exposure: effects from climate change impacts in the rest of the world. Read more on supply chains
