Yes there are measurements from other planets that go back several years but that does not constitute a continuous measurement period. The temporal and spatial coverage of such measurements varies each time and is naturally very limited in this respect. Measurements taken relatively close together in time have shown stark differences that cannot simply be said to be climate change but rather are natural short time-scale variations in time and space as you would find if you compared the temperature in the Sahara and the Antarctic on different days and with each other. The data that does exist has not been sufficient for scientists to produce running averages with anything like the reliability of those used for earth. Long-term trends are built using ''these'' figures not simply single temperature measurements from irregular times and places. As such it is not possible to make any accurate claims about climate change on these planets within the past few decades based on the available data.
