The latest Intergovernmental Panel on Climate Change (IPCC) Special Report highlights the urgency of prioritizing timely, ambitious and coordinated action to address unprecedented and enduring changes in the ocean and cryosphere.
Meteoworld : September 2019
The IPCC Special Report on the Ocean and Cryosphere in a Changing Climate spotlights the benefits of ambitious and effective adaptation for sustainable development and, conversely, the escalating costs and...

The high mountain regions are home to 1 billion people, are the source of freshwater to at least 1.9 billion people and are crucial for regulating the global climate system. Preservation of mountain ecosystem functions is therefore essential to global water, food and energy security.

Glacier melt will inevitably increase in the future, both for 1.5°C and 2°C temperature increases, with global impacts for water resources and sea level rise.

Glacier shrinkage – accelerated over the last decades due to climate change – is exposing large areas in mountain regions worldwide. But an even dire consequence of the melting ice is the forming of more glacier lakes, which are increasing in size. Glacial lakes have caused some of the world’s most devastating floods, for example, in the Andes, Himalayas and Alps, where thousands of human lives were lost and huge infrastructure damages reported (Carrivick and Tweed, 2013; Bajracharya et al., 2007; Carey 2005).

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.

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...
