Feb 19, 2025 · 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 ...

Feb 24, 2025 · 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 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 …

Mar 3, 2025 · Climate informed energy planning: The report illustrates the potential applications of seasonal forecasts as a valuable tool for energy planning and management. Seasonal climate forecasts empower stakeholders to anticipate supply–demand fluctuations, optimize grid operations and enhance energy system resilience.

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 ...

GCOS Climate monitoring principles. The GCOS Climate Monitoring Principles are intended to provide guidance to those involved in the design, development, deployment, and management of observing systems for climate-related needs across all domains (surface, above surface, and subsurface), all observing platforms, and all essential climate variables (ECVs).

Climate change impacts gripped the globe in 2024, with cascading impacts from mountain peaks to ocean depths and on communities, economies and the environment. WMO The year 2024 is set to be the warmest on record , capping a decade of unprecedented heat fuelled by human activities, according to the World Meteorological Organization (WMO).

Mar 19, 2024 · 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, and in the ...

For March-May 2025, sea surface temperature anomalies in the Niño 3.4 and Niño 3 regions are expected to return to near-average, indicating a neutral state in the El Niño–Southern Oscillation (ENSO). Further west, in the Niño 4 region, the sea surface temperature anomaly is also forecast to decrease to near-average. The strength of the Indian Ocean Dipole (IOD) index is likewise ...

Even so, tracked climate finance flows represent only approximately 1% of global GDP, according to the Climate Policy Initiative. There is a large financing gap. In an average scenario, for a 1.5°C pathway, annual climate finance investments need to grow by more than six times, reaching almost USD 9 trillion by 2030 and a further USD 10 ...
