Summary:
- This article discusses a new analysis by University of Toronto atmospheric physicists that has identified an error in widely cited snow cover observations.
- The researchers found that the data used to track changes in global snow cover over the past several decades contained a systematic bias, leading to an overestimation of the decline in snow cover.
- Correcting this error shows that snow cover has actually been more stable over the past 50 years than previously thought, which has important implications for our understanding of climate change and its impacts.
