As atmospheric CO 2 continues to increase, more and more CO 2 enters the ocean, which reduces pH (pH is a measure of acidity, the lower the pH, the more acidic the liquid) in a process referred to as ocean acidification. Declines in surface ocean pH due to ocean acidification are already detectable and accelerating.

Switzerland has announced a major contribution to an international initiative to strengthen early warning systems in vulnerable low-income countries to support climate change adaptation, disaster risk reduction and sustainable development. The announcement of 9 million Swiss francs in new funding came at the United Nations climate change conference in Katowice, Poland (COP24).
The Global Climate Observing System (GCOS) is a United Nations-ratified programme which regularly assesses the status of global climate observations and produces guidance for its improvement. It is co-sponsored by...

An initiative to strengthen multi-hazard early warning systems in the Caribbean was launched on November 20 during the dry season Caribbean Climate Forum (CariCOF) meeting in Barbados. The Caribbean region is highly exposed to high-impact hydrometeorological hazards such as hurricanes and tropical storms, causing floods, landslides and storm surge. In 2017, Hurricane Irma caused massive destruction in Barbuda resulting in the subsequent full evacuation of the island while Hurricane Maria caused devastation Dominica. Barbados suffered from flooding as a result of Tropical Storm Kirk in...

A concerted international campaign to improve predictions of weather, climate and ice conditions in the Arctic and Antarctic has been launched to minimize the environmental risks and maximize the opportunities associated with rapid climate change in polar regions and to close the current gaps in polar forecasting capacity. The Year of Polar Prediction takes place from mid-2017 to mid-2019 in order to cover an entire year in both the Arctic and Antarctic and involves the World Meteorological Organization (WMO), Germany’s Alfred Wegener Institute (AWI) and a wide array of partners around the...

19 May 2017 - Climate change, associated extreme weather and demographic shifts means that record numbers of people are exposed to floods, heatwaves and other hazards. Improved early warning systems and more coordinated disaster risk reduction are therefore more important than ever before. To meet the growing challenges, an international conference will launch a concerted drive to improve warnings for an interlocking range of hazards and to translate these warnings into effective action on the ground.
