The 2021 State of the Climate report, led by the U.S. National Oceanic and Atmospheric Administration (NOAA)’s National Centers for Environmental Information (NCEI), was released in August – combining efforts from more than 530 scientists from 67 countries. The report is an annual summary of patterns and changes in the global climate system. Key findings for 2021 included record high emissions of the dominant greenhouse gases, continued warming trends, record-breaking ocean heat and global sea levels, and increased tropical cyclone activity. Cryosphere-specific impacts in 2021 included global glacier mass loss for the 34th consecutive year, record high permafrost temperatures, extreme Arctic summer heat events, the first recorded rainfall at high point of the Greenland Ice Sheet, and continued decline in volume of Arctic sea ice. The report provides more compelling evidence of the increasingly severe global impacts of climate change and the need for rapid emissions reductions.
