WMO has adopted a unified Earth system approach to ensure weather, water and climate decisions are better informed by an integrated monitoring and prediction of all relevant Earth system components. This includes extending its reach to the furthest and most frigid parts of the globe, the Arctic, Antarctica and the high-mountain regions, where the cryosphere is a prominent feature.

Record high temperatures, rain and the collapse of an ice shelf in East Antarctica have prompted questions and concern about the possible role of climate change in the coldest and driest part of the world.
Water stress, water-related hazards and water quality pose increasing challenges to modern society. And yet, the capacity to monitor and manage this vital resource is fragmented and inadequate. Billions of people around the world also feel the impact of climate change through water.
The WMO's Global Cryosphere Watch (GCW) fosters international coordination and partnerships between scientific and operational communities with the goal of meeting the cryosphere data and information need of Members and partners, in support of Earth system monitoring, modeling and prediction. GCW operates under the remit of the Infrastructure Commission (INFCOM).

The new issue of the World Meteorological Organization’s Bulletin is dedicated entirely to international data exchange in Earth system monitoring and prediction and to the role of WMO data policy in establishing and maintaining this exchange.

Climate change has accentuated natural hazards, including flash floods caused by melting of snow and ice in many regions of the world. The Himalayas, which are the third largest deposit of ice and snow in the world after Antarctica and the Arctic, are heavily impacted. This was highlighted by a disaster in February in Uttarakhand in the Indian Himalayas, after a part of the Nanda Devi glacier broke off and collapsed causing a massive flood in the Rishi Ganga /Dhauliganga river. This destroyed two hydropower plants, burst open dams, and led to a large number of casualties and widespread...

The World Meteorological Organization is supporting the First World Virtual High Mountain Summit, which is spearheaded by Colombia. It brings together more than 50 participants from four continents from the public and private sectors, academia, and civil society, to discuss biodiversity and ecosystem services as well as climate variability and change.

The most ambitious Arctic research expedition ever undertaken has come to a successful end after spending more than a year researching climate change in the Arctic, Drifting with the ice, the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) endured the extreme cold, Arctic storms, a constantly changing floe – and the challenges posed by the coronavirus pandemic.

The World Meteorological Organization has recognized a temperature of -69.6°C (-93.3°F) at an automatic weather station in Greenland on 22 December 1991 as the lowest ever recorded in the Northern Hemisphere. The temperature record was uncovered after nearly 30 years by “climate detectives” with the WMO Archive of Weather and Climate Extremes. It eclipses the value of -67.8°C recorded at the Russian sites of Verkhoyanksk (February 1892) and Oimekon (January 1933). The world’s lowest temperature record, of -89.2°C (-128.6°F) on 21 July 1983, is held by the high-altitude Vostok weather station...

Arctic sea ice – a key climate change indicator - has reached its annual minimum extent after the summer melt season. It was the second lowest extent only after the record low observed in 2012.
