The pages below include information around what climate is and what influences it, as well as how and why our climate is changing. You can also read about the work we undertake, both in the UK and internationally, to improve understanding of climate variability and change, and to help prepare for future changes.

The Met Office Hadley Centre is world-renowned for climate monitoring and research. Latest news from our research programmes can be found on our Climate News page, with more in-depth information on our Research web pages. We are also home to long-running monitoring programmes for global and UK climate, and this data is free to download from our HadObs page
