Global observations of surface and upper air temperature and humidity, surface pressure and precipitation are used to provide advice on global climate variability and change.

Temperature, precipitation and humidity and their extremes can have a major impact on our lives. Observational datasets are used to monitor land and atmospheric climate variables, to understand how the climate has changed over time and to examine the occurrence of extremes in temperature and heat

Global Climate Observing System The Global Climate Observing System (GCOS) is intended to be a long-term, user-driven operational system capable of providing the comprehensive observations required for monitoring the climate syst

GCOS is vital for: detecting and attributing climate change; assessing the impacts of climate variability and change; supporting research toward improved understanding, modelling and prediction of the climate system. It addresses the total climate system including physical, chemical and biological

New tool shows what climate change might look like in your area

climate projections really puts future extremes into context. We’ve seen a raft of record-breaking weather over the past few years, and when you put that side by side with the projections it really brings to life what the weather could look like if we don’t significantly reduce greenhouse gas emissions

in developed countries than for countries in the global south. Confidence in climate attribution analysis relies on high quality observational records, climate models’ abilities to simulate a particular type of event, and scientific understanding of how natural variability and climate change may influence

in that period including an attribution study of the UK’s record-breaking annual temperature in 2022, where human-induced climate change made this event around 160 times more likely.  In December 2023, the Met Office annual global temperature forecast was published. Global average temperature rise

2024 was the warmest year on record globally and the first year that was likely more than 1.5°C above pre-industrial levels: a stark reminder global temperatures are continuing to rise.

exceeded the previous warmest year – 2016 - by 0.17°C, making 2024 and 2023 the warmest and second-warmest years on record.   A number of global climate centres will be releasing their 2024 average temperature figures today.  The latest figures highlight how the world is getting closer to breaching

Climate risk report for the Southern Africa region

The climate risk report for the Southern Africa region is part of a series of regional climate risk reports the Met Office has produced in collaboration with ODI and commissioned by FCDO to provide evidence to the UK Government in support of adaptation and resilience planning and investments
