Scientists have been observing changes in the climate that cannot be attributed solely to natural influences. These changes are occurring rapidly, are significant, and will have consequences for this and future generations. Changes in climate variability and extremes driven by human-induced climate change are some of the key challenges facing humanity.
Strengthen the global observing systems through full implementation of WMO Integrated Global Observing System (WIGOS) and WMO Information System (WIS) for robust, standardized, integrated, accurate and quality assured relevant observations of the Earth System to support all WMO priorities and expected results.

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.
WMO supports UNFCCC through a wide range of scientific and technical inputs, including its support through the IPCC, thereby contributing to adaptation, mitigation and capacity development. Every year, WMO participates in sessions of the Conference of Parties (COP) of UNFCCC, providing the latest scientific advice and information to governments, including the Statement on the State of the Global Climate and the Greenhouse Gas Bulletin.
Regional Climate Outlook Forums (RCOFs) produce consensus-based, user-relevant climate outlook products in real time through regional cooperation and partnership in order to reduce climate-related risks and support sustainable development for the coming season in sectors of critical socioeconomic significance for the region in question.
