Amazonia hosts the Earth’s largest tropical forests and has been shown to be an important carbon sink. This carbon sink seems to be in decline, however, as a result of factors such as deforestation and climate change, according to a new paper published in Nature.

WMO has issued its annual Airborne Dust Bulletin on the incidence and hazards of sand and dust storms in 2020. The impacts on health, the environment and economies have been highlighted once again this year as massive sand plumes have darkened skies and affected air quality in many parts of Africa, Asia, the Americas and Europe and travelled hundreds of miles over the Atlantic.

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).

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.

A World Meteorological Organization Task Team has issued its first report on Meteorological and Air Quality factors affecting the COVID-19 pandemic. It cautions that weather and climate conditions, including the onset of higher temperatures in the northern hemisphere spring, should not be used as a trigger to relax measures to halt the spread of the virus.
