DECC has published a paper on climate statistics examining the question of whether they are "coherent and accessible".
It's actually very interesting. Take this for example:
DECC statisticians told us that they manage a shared mailbox for queries about climate change statistics, and that over the two years that this mailbox has been in place not a single enquiry has been received about wider climate change statistics. In addition, we were told that a recent user consultation exercise run by DECC statisticians did not highlight any issues concerning user needs for more general “climate change” data. DECC has concluded that it “does not appear to be the case that users see DECC as the organisation responsible for pointing them in the right direction if needed”.
