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.
Supplement: State of Climate Services 2024 Supplement: Significant Weather & Climate Events 2024 The 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.
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.
Global climate predictions show 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, according to a new report from the World Meteorological Organization (WMO).
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.
A specialized agency of the United Nations whose mandate covers weather, climate and water resources. The UN’s scientific voice on the state and behaviour of our atmosphere and climate.
The alarming streak of exceptional temperatures continued in 2025, which is set to be either the second or third warmest year on record, according to the State of the Global Climate Update from the World Meteorological Organization (WMO).
The WMO Climate Services Information System (CSIS) is the principal mechanism through which information about climate – past, present and future – is routinely produced, archived, analysed, modelled, exchanged and processed. The CSIS is the “operational core” of the Global Framework for Climate Services (GFCS), the United Nations-led initiative spearheaded by WMO to support the ...
The State of Climate Services report says that in 2024, one third of National Meteorological and Hydrological Services (NMHSs) provide climate services at an ‘essential’ level, and nearly one third at an ‘advanced’ or `full’ level. It says that countries in Asia and Africa, in particular, have made strides in boosting their capacity thanks to targeted adaptation funding. The report ...
The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on record, with widespread and prolonged heatwaves. Record-high sea surface ...
