Recalculating seasonal warming and cooling trends

Statistical analyses of seasonal warming and cooling trends find that treating individual seasonal records as independent records in linear regressions can lead to the misidentification of seasonal temperature shifts as statistically significant; for example, the study finds that from 1957 to 2013, spring is the only season with significantly rising temperatures at Byrd Station in West Antarctica, a finding that contradicts previous reports that spring and winter at Byrd Station have had significantly rising temperatures during this period. - Read at PNAS
