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. The global mean temperature in 2023 was about 1.45°C above the 1850-1900 average. The warmest year on record, because of long-term ...
Challenges. 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. 1.45°C. The global mean temperature in 2023 was about 1.45°C above the 1850-1900 average. 2023.
The WMO State of the Climate 2024 Update once again issues a Red Alert at the sheer pace of climate change in a single generation, turbo-charged by ever-increasing greenhouse gas levels in the atmosphere. 2015-2024 will be the warmest ten years on record; the loss of ice from glaciers, sea-level rise and ocean heating are accelerating; and extreme weather is wreaking havoc on communities and ...
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 ...
The provisional State of the Climate 2021 report is released at the start of the UN Climate Change negotiations, COP26, in Glasgow. It provides a snapshot of climate indicators such as greenhouse gas concentrations, temperatures, extreme weather, sea level, ocean warming and ocean acidification, glacier retreat and ice melt, as well as socio ...
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 ...
State of the Global Climate. Since 1993, the World Meteorological Organization (WMO), through the Commission for climatology and in cooperation with its Members, has issued annual statements on the status of the global climate to provide credible scientific information on climate and its variability. Climate change indicators reached record ...
AdobeStock/prirach. The WMO State of the Global Climate in 2021 report confirmed that four key climate change indicators – greenhouse gas concentrations, sea level rise, ocean heat and ocean acidification – set new records in 2021. This is yet another clear sign that human activities are causing planetary scale changes on land, in the ocean ...
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 rising.
The report on the State of the Global Climate 2020 documents indicators of the climate system, including greenhouse gas concentrations, increasing land and ocean temperatures, sea level rise, melting ice and glacier retreat and extreme weather. It also highlights impacts on socio-economic development, migration and displacement, food security ...
