Geneva, Switzerland (WMO) – The Earth’s climate is more out of balance than at any time in observed history, as greenhouse gas concentrations drive continued warming of the atmosphere and ocean and melting of ice, according to the World Meteorological Organization (WMO). These rapid and large-scale changes have occurred within a few decades but will have harmful repercussions for hundreds ...
We are asking you to share your predictions on questions related to the potential impact of climate change in the years, decades, and centuries to come. Due to the long-term nature of this Challenge, questions will not be officially scored. Forecasting on all questions will be suspended on 15 October 2022.
Will climate change be a cause of human extinction by 2100? Closed 12:01AM 1 1
Supplement: State of Climate Services 2024Supplement: Significant Weather & Climate Events 2024The clear signs of human-induced climate change reached new heights in 2024, which was likely the first calendar year to be more than 1.5°C above the pre-industrial era, with a global mean near-surface temperature of 1.55 ± 0.13 °C above the 1850-1900 average.This is the warmest year in the 175 ...
Climate change is the term used to describe changes in the state of the climate that can be identified by changes in the average and/or the variability of its properties and that persists for an extended period, typically decades or longer.
The WMO State of the Global Climate report 2022 focuses on key climate indicators – greenhouse gases, temperatures, sea level rise, ocean heat and acidification, sea ice and glaciers. It also highlights the impacts of climate change and extreme weather. Drought, floods and heatwaves affect large parts of the world and the costs are risingGlobal mean temperatures for the past 8 years have ...
Copernicus Climate Change Service and the World Meteorological Organization have issued their second joint annual report on the European State of the Climate.
Over that period, average global sea level has: Sea level is a global climate change indicator. Through continuous long-term measurements of global sea level, scientists can see the ocean’s role in climate and the effects of a changing climate on the ocean. Since 1993, global mean sea level has risen by about 4 inches (10 centimeters).
NASA and the Federal Emergency Management Agency (FEMA) have released a guide that provides resources for adapting to and mitigating impacts of climate change. The guide, Building Alliances for Climate Action, includes various perspectives, stories, insights, and resources about climate change to help individuals and organizations make informed decisions.
The leading cause of coral bleaching is rising ocean temperatures due to climate change. Although runoff and pollutants, sunlight, and low tides can impact coral, those impacts normally occur near the shoreline in shallow waters.
Clouds and aerosols are two of the most important, but least understood, aspects of climate change. How much do you know about them?

Water conservation works, but climate change is outpacing it: Phoenix, Denver and Las Vegas offer a glimpse of the future
Which EU Member State's commissioner-designate will Ursula von der Leyen first nominate to be assigned the European Commission's (EC's) Directorate-General for Climate Action?
Climate change is actively reshaping how plastics behave in the environment, making them more mobile, persistent and harmful across ecosystems. Recent analysis examines the influence of climate-driven changes in temperature, weather events and Earth system processes on plastic pollution. Addressing these interconnected risks requires aligning plastic policy with climate action – not as ...
A future statement is a directive to the compiler that a particular module should be compiled using syntax or semantics that will be available in a specified future release of Python. The future statement is intended to ease migration to future versions of Python that introduce incompatible changes to the language. It allows use of the new features on a per-module basis before the release in ...

Climate is the average weather conditions for a particular location over a long period of time, ranging from months to thousands or millions of years. WMO uses a 30-year period to determine the average climate.
WMO’s State of the Global Climate report 2025 confirms that 2015-2025 are the hottest 11-years on record, and that 2025 was the second or third hottest year on record, at about 1.43 °C above the 1850-1900 average. Extreme events around the world, including intense heat, heavy rainfall and tropical cyclones, caused disruption and devastation and highlighted the vulnerability of our inter ...
The State of the Global Climate 2023 report shows that records were once again broken, and in some cases smashed, for greenhouse gas levels, surface temperatures, ocean heat and acidification, sea level rise, Antarctic sea ice cover and glacier retreat. Heatwaves, floods, droughts, wildfires, and rapidly intensifying tropical cyclones caused misery and mayhem, upending everyday life for ...
European State of the Climate : extreme events in warmest year on record
WMO has taken over responsibility for hosting the official Archive of Weather and Climate Extremes - the equivalent of the Guiness Book of records on heat, rainfall, wind, lightning and many other phenomena. It has also issued new guidelines on the evaluation of new records.
The WMO Global Annual to Decadal Climate Update (2025–2029) projects that global temperatures are expected to continue at or near record levels in the next five years, increasing climate risks and impacts on societies, economies and sustainable development.The report forecasts that the annually averaged global mean near-surface temperature for each year between 2025 and 2029 is predicted to ...
