Changes in the phase of the annual cycle of surface temperature Variations in the seasonal cycle of temperatures at the Earth's surface are spatially mapped on both land and sea, and trends in the recent past (1954-2007) are compared with those occurring earlier (1900-1954). Assuming that the earlier part of the temperature record is dominated by natural variations, the recent trends seem highly anomalous: temperatures on land show a shift to earlier seasons by 1.7 days, and the amplitude of the cycle has decreased in this period.

The Antarctic Peninsula is known to be warming rapidly, but the overall pattern of climate change for the full Antarctic continent has been uncertain. This work finds that the entire continent is warming at a rate of 0.12 ± 0.07 °C per decade, with stronger warming in winter and spring and over West Antarctica.
