'Data arising from this project are available from the state of the environment indicator URL given below.'
The annual cycle can be clearly seen in the plots of monthly mean air temperatures, though it is much smaller for Macquarie Island with its maritime climate. This cycle makes it hard to see long-term trends but can be removed by using monthly anomalies, which show the difference between the value for a given month and the long-term mean value for that month.
The anomaly data show significant warming at Macquarie Island (over half a degree in 50 years). There appears to be no such trend at the Antarctic sites.
It should be noted that the data have not been corrected for any changes in site location, site exposure, instrumentation or observing practices.
Though recent temperatures for Macquarie Island have decreased slightly, the overall warming trend there (about half a degree in 50 years) remains significant. There is still no evidence of any warming trend at the Antarctic sites.
