WMO supports its Members to understand the Earth’s climate on global to local scales by developing technical standards for observing instruments and ensuring that the collected data are quality controlled and comparable, by monitoring the current climate and by ensuring that skilful predictions of the climate over the coming weeks, months, seasons and years as well as climate change projections over the coming decades to longer periods are available and freely accessible by the Members. All of these cascading sources of information are essential for climate-smart decision making at all levels to deal with climate risks. Climate information is also essential for monitoring the success of mitigation efforts such as reduction of greenhouse gas emissions that contribute to climate change, as well as for promoting efforts to increase energy efficiency, to transition to a carbon-neutral economy and effectively pursue Sustainable Development Goals (SDGs). The most widely used climate information products of the WMO include:
