This is the 33rd issuance of the annual assessment now known as State of the Climate, published in the Bulletin since 1996. As a supplement to the Bulletin, its foremost function is to document the status and trajectory of many components of the climate system.

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.

This BAMS special report presents assessments of how human-caused climate change may have affected the strength and likelihood of individual extreme events.

The gases heating the planet in 2018 were higher than humans have ever recorded, according to an authoritative new report from the American Meteorological Society and the US government. Greenhouse gas levels topped 60 years of modern measurements and 800,000 years of ice core data, the study found.

This BAMS special report presents assessments of how human-caused climate change may have affected the strength and likelihood of individual extreme events. This is the second year that scientists have identified extreme weather events that they said could not have happened without warming of the climate through human-induced climate change.

Last year was the warmest ever recorded on Earth that didn’t feature an El Niño, a periodic climatic event that warms the Pacific Ocean, according to the annual state of the climate report by 500 climate scientists from around the world, overseen by the National Oceanic and Atmospheric Administration (Noaa) and released by the American Meteorolo

Last year’s record global average temperatures, extreme heat over Asia, and unusually warm waters in the Bering Sea would not have been possible without human-caused climate change, according to a new report published in the Bulletin of the American Meteorological Society (BAMS).

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.

This special report in Bulletin of the American Meteorological Society presents assessments of how climate change may have affected the strength and likelihood of individual extreme events. 

This fifth edition of explaining extreme events of the previous year (2015) from a climate perspective continues to provide evidence that climate change is altering some extreme event risk.
