flooded farmers fieldScenes of flooding and storms show us just how much weather and climate can affect our lives.

Understanding and predicting what the coming winter might bring, or predicting how climate will change over the next century is of vital importance - both for our economy and for society.

Climate can be thought of as the average or typical weather conditions we experience. Scientists know that climate varies naturally on many timescales and they know that people are affecting climate - particularly through emissions of greenhouse gases.

At the National Centre for Atmospheric Science, scientists are investigating how natural and human factors are affecting climate and what this means for the future.

Our research into long-term global changes helps to address many fundamental questions about our climate.
