Climate - World Meteorological Organization 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
State of the Global Climate 2024 - wmo. int 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 - World Meteorological Organization 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
State of the Climate 2024 Update for COP29 - wmo. int 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
WMO Global Annual to Decadal Climate Update (2025-2029) 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
2024 State of Climate Services - wmo. int 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
State of the Climate in Africa 2024 - wmo. int The Key Climate Indicators dashboard is a companion to the State of the Climate in Africa reports State of the Climate in Africa 2024: Figures Figures as annexes to the State of the Climate in Africa 2024 report, offering visual insights and data highlights that complement the main findings
Global Climate Observing System (GCOS) The Global Climate Observing System (GCOS) is co-sponsored by the World Meteorological Organization (WMO), the Intergovernmental Oceanographic Commission of the United Nations Educational, Scientific and Cultural Organization (IOC-UNESCO), the United Nations Environment Programme (UN Environment), and the International Science Council (ISC)
About Essential Climate Variables - gcos. wmo. int 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)
Global climate predictions show temperatures expected to remain at or . . . The WMO State of the Global Climate 2024 report presented three methods for estimating the current global warming level, with central estimates ranging from 1 34°C to 1 41°C compared to the 1850-1900 baseline based on a range of methods – although it noted the uncertainty ranges in global temperature statistics and reported a 90% confidence
