'Data arising from this project are available from the state of the environment indicator URL given below.'
The annual cycle can be seen in the plots of highest monthly air temperatures. 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, but not 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.
There has been a slight reduction in the highest monthly air temperature over recent years at Macquarie Island, as can be seen in the anomaly data. However, over the whole period of record significant warming has taken place there. No such warming trend is evident for the Antarctic sites.
