NOAA’s 2023 Arctic Report Card documents new records showing that human-caused warming of the air, ocean and land is affecting people, ecosystems and communities across the Arctic region, which is heating up faster than any other part of the world.

Rick Thoman co-authors the 2022 NOAA Arctic Report Card that reveals shifts in Arctic seasons, widespread disturbance, and the value of diverse observations.
Improved Predictability of Sea Ice Break-Up and Freeze-Up for Arctic Coastal Communities and Ecosystems
A new COM-funded Arctic sea ice study improves predictions of sea ice freeze-up and break-up in coastal regions by identifying local indicators.
New research demonstrates the presence of solid organic-coated ammonium sulfate particles in the Arctic boundary layer. As the Arctic loses ice, researchers expect to see more of these unique particles formed from oceanic emissions combined with ammonia from birds, that can change how clouds form and climate.
Understanding natural climate variability can improve predictions of sea-ice coverage at short and long term scales, study says
A CPO-funded study published on Nature Climate Change demonstrates how understanding natural climate variability can improve predictions of sea-ice coverage at short and long term scales.
A CPO-funded study in the Journal of Climate documents research on sea ice to understand essential processes in the climate system and other ecological systems.
New findings suggest ice sheets, such as the Greenland Ice Sheet and Antarctica, could be at risk of collapsing and raising sea levels more than most models currently predict based on global warming alone.
A study funded by the CPO’s Climate Observation Division confirms previous research suggesting spring clouds may be influencing arctic sea ice concentrations in the fall.
“There is little doubt that we will see a decline in Arctic sea ice cover in this century in response to anthropogenic warming, and yet internal climate variations and other external forcings could generate considerable spread in Arctic sea ice trends on decadal timescales,” begins a newly released article by Yeager et al., in Geophysical Research Letters.
The Climate.gov team provided visual highlights to accompany the latest installment of NOAA’s Arctic Report Card, released December, 15 2015.
