An international, peer-reviewed publication released each summer, the State of the Climate is the authoritative annual summary of the global climate published as a supplement to the Bulletin of the American Meteorological Society.

Arctic wetlands play a number of crucial environmental roles, but they continue to be degraded and lost, with potentially dire global consequences. This report offers insights and identifies knowledge gaps, with the aim of supporting sustainable development and resilience in these areas.

A drastic drop in caribou and shorebird populations is a mirrored image of the dire modifications unfolding on the Arctic tundra, based on a new report from the Arctic Council. The terrestrial Arctic spans roughly 2.7m sq miles (7m sq km), marked by excessive chilly, drought, sturdy winds and seasonal darkness.

New observations show that the increase in Arctic average surface temperature between 1979 and 2019 was three times higher than the global average during this period – higher than previously reported - according to the Arctic Monitoring and Assessment Programme (AMAP).

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.

The Arctic Report Card is an annual compilation of original, peer-reviewed environmental observations and analyses of a region undergoing rapid and dramatic alterations to weather, climate, oceanic, and land conditions.

Southwestern China (SWC) has suffered from increasing frequency of heat wave (HW) in recent summers. While the local drought-HW connection is one obvious mechanism for this change, remote controls remain to be explored. Based on ERA-5 reanalysis, it is found that the SWC summer HWs are significantly correlated with sea-ice losses in the Barents Sea, Kara Sea and the Arctic pole.

Climate change effect on water security will present high risk to global security in the next ten years warns this inaugural World Climate and Security report released by the International Military Council on Climate and Security. It is the first report of its kind, and is intended to inform future climate and security policy and analysis.

Atmospheric researchers at the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have now developed a climate model that can accurately depict the frequently observ

Permafrost landscapes are changing around the Arctic in response to climate warming, with coastal erosion being one of the most prominent and hazardous features. Using drone platforms, satellite images, and historic aerial photographs, we observed the rapid retreat of a permafrost coastline on Qikiqtaruk – Herschel Island, Yukon Territ
