Divergent consensuses on Arctic amplification influence on midlatitude severe winter weather
- States that the Arctic has warmed more than twice as fast as the global average since the late twentieth century, a phenomenon known as Arctic amplification (AA)
- States that recently, there have been considerable advances in understanding the physical contributions to AA, and progress has been made in understanding the mechanisms that link it to midlatitude weather variability.
- Observational studies overwhelmingly support that AA is contributing to winter continental cooling
- Divergent conclusions between model and observational studies, and even intramodel studies, continue to obfuscate a clear understanding of how AA is influencing midlatitude weather
