Significant Warming of the Antarctic Winter Troposphere

We report an undocumented major warming of the Antarctic winter troposphere
that is larger than any previously identified regional tropospheric warming on
Earth. This result has come to light through an analysis of recently digitized
and rigorously quality controlled Antarctic radiosonde observations. The data
show that regional midtropospheric temperatures have increased at a
statistically significant rate of 0.5° to 0.7°Celsius per decade over the past
30 years. Analysis of the time series of radiosonde temperatures indicates that
the data are temporally homogeneous. The available data do not allow us to
unambiguously assign a cause to the tropospheric warming at this stage.
