NCAS Long-term global change

Lead Research Organisation: NERC National Ctr for Atmospheric Sci


Human activities are now the major driver of changes in the atmosphere and its interactions with earth’s climate. NCAS is investigating how our atmosphere and climate are changing, so that society has scientific evidence to inform adaptation and mitigation policies that respond to this unprecedented global challenge. Our priority research activities address three key areas of scientific uncertainty, and make use of our modelling capabilities, our long-term observations of the atmosphere, and laboratory studies: climate projections, changes in atmospheric composition, and changes in aerosols and clouds.
Description This programme has been influential in a number of different areas relating to long term changes to our atmosphere, by increasing the understanding of:
1. The fundamental processes that cause changes in the composition of the atmosphere.
2. The ways in which the composition of the atmosphere affects and responds to changes in climate on timescales from years to millenia.
3. The role of clouds in climate change.
4. The impacts of climate change, for example on sea level rise, weather patterns and the hydrological cycle.
Exploitation Route The NCAS long term global change programme provides a foundation for a wide range of research activities in the academic community and also informs policy making on climate change.

Description NCAS has made major contributions to international policy work to control ozone depleting substances, detailed in a case study which scored 3.5 in the recent NERC Centre Evaluation. NCAS has made major contributions to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change, including co-leading (with the Met Office) the UK's contribution to the Sixth Coupled Model Intercomparison Project (CMIP6) through the UKESM model and providing Lead Authors, Contributing Authors and reviewers for the report.
