The interconnection between climate and health is undeniable. The climate, exacerbated by climate change, poses systematic and serious threats to human health. Climate change is documented to be impacting human health in many complex ways, includi...

More than 2 billion people are living in countries under water stress and 3.6 billion people face in...

Between 1970 and 2019, 79% of disasters worldwide involved weather, water, and climate-related hazards. These disasters accounted for 56% of deaths and 75% of economic losses fr...

The report provides case studies, examples and explanations as to the role of climate information and services to support agriculture in the face of climate variability and change, assesses gaps and makes recommendations. This analysis helps highl...

WMO’s State of Global Water Resources report for 2022 has been launched, following the success of the first pilot report launched last year in response to calls made at various global forums for an independent and consistent assessment of global w...

Impacts of climate variability and change are often felt through water. The dynamics of the water cycle and its interactions with human society result in varying spatio-temporal patterns of water resource availability and impacts of water-related ...

The latest analysis of observations from the WMO Global Atmosphere Watch (GAW) in situ observational network shows that the globally averaged surface concentrations(2) for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) reached new hig...

The latest analysis of observations from the WMO GAW in situ observational network shows that globally averaged surface mole fractions(4) for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) reached new highs in 2021, with CO2 at 415.7±...

The latest analysis of observations from the WMO GAW in situ observational network shows that globally averaged surface mole fractions(1) for CO2, methane (CH4) and nitrous oxide (N2O) reached new highs in 2020, with CO2 at 413.2 ± 0.2 ppm(2), CH4...

The latest analysis of observations from the WMO GAW Programme shows that globally averaged surface mole fractions(1) calculated from this in-situ network for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) reached new highs in 2018, w...

The latest analysis of observations from the WMO GAW Programme shows that globally averaged surface mole fractions(1) calculated from this in situ network for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) reached new highs in 2017, w...

The rate of increase of atmospheric carbon dioxide (CO2) over the past 70 years is nearly 100 times larger than that at the end of the last ice age. As far as direct and proxy observations can tell, such abrupt changes in the atmospheric levels of...

Average daily CO,emissions from 5 February to 6 May 2020 (redarea) and average ofthe previous years during the same period(grey area) for three European cities. The dark grey horizontalbars cover periods of officiallockdown, while the light grey b...

In 2015, Earth experienced the start of a strong El Niño event. El Niño events are natural fluctuations of the climate system where unusually warm water accumulates in the equatorial Pacific Ocean. El Niño events are associated with abnormal weath...

Global particulate matter concentrations in 2023 as recorded by two products Johannes Flemming, Allie Collow Particulate matter at the surface that is smaller than 2.5 micrometres in diameter is referred to as PM2.5. In ambient air, PM2.5 is a sev...

Looking to the future, regional air quality may become increasingly influenced by wildfires, especially in light of regional climate change impacts. A measurable effect of climate change on a regional scale, affecting the frequency and intensity o...

Inhaling particulate matter smaller than 2.5 micrometres (PM2.5) over long periods is a severe health hazard. Human and natural sources contribute to PM2.5 pollution in varying proportions at the global scale. Using the PM2.5 data from the Coperni...

At the half-time point of the 2030 Agenda, the science is clear – the planet is far off track from meeting its climate goals Anthropogenic climate change has resulted in widespread and rapid changes in the atmosphere, ocean, cryosphere and biosphe...

United in Science provides an overview of the most recent science related to climate change, impacts and responses from the World Meteorological Organization (WMO) and partner organizations. At a time when urgent action to address climate change i...
