The World Meteorological Organization’s Executive Council meets in virtual session from 14 to 25 June , with a focus on strengthening and scaling up weather, climate, water and environmental-related services to meet ever growing needs. It will also discuss a major update to WMO’s data policy, closing the gap in the global observing system and a plan of action for hydrology.

Facing the triple threat of climate change, loss of nature and pollution, the world must deliver on its commitment to restore at least one billion degraded hectares of land in the next decade – an area about the size of China. Countries also need to add similar commitments for oceans, according to a new report by the UN Environment Programme (UNEP) and the Food and Agriculture Organization of the UN (FAO).
When it comes to the weather and climate, most of us think only about what is happening in the atmosphere. If we ignore the ocean, however, we miss a big piece of the picture: covering some 70% of the Earth’s surface, the ocean is a major driver of the world’s weather and climate.

A new World Meteorological Organization bulletin on Aerosols examines the impact of biomass burning (wildfires and open burning for agriculture) on climate and air quality. It covers the episodes of the 2019/2020 Australian bushfires, the 2015 Indonesia peatfires and smoke transport from boreal forest fires to the Arctic.

A Global Methane Assessment released by the Climate and Clean Air Coalition (CCAC) and the United Nations Environment Programme (UNEP) shows that human-caused methane emissions can be reduced by up to 45 per cent this decade.
The impact of aerosols on the atmosphere is widely acknowledged as one of the most significant and uncertain aspects of climate change projections. The observed global warming trend is considerably less than expected from the increase in greenhouse gases, and much of the difference can be explained by aerosol effects. Aerosols impact climate through direct scattering and absorption of incoming solar radiation and trapping of outgoing long-wave radiation as well as through alteration of cloud optical properties and the formation of clouds and precipitation.
