Another heat pump question

    I've already posted a variation on this query to the Green forum
    but I've not seen any responses.

    Someone told me recently they had heard an "expert" on BBC state
    that people would be mad not to consider ground source heat pumps
    on account of the predicted average temperature increases (2-3degrees
    or more) resulting from climate change.
    Assuming the climate change is a given is it over simplistic or not to
    assume that heat pump efficiencies will increase as average ground
    temperatures rise ?

    It seemed a perverse argument - .. i.e cash in on global warming by
    getting more heat from the ground.

    I would have felt that the increasing temps would mean less space
    heating requirements and in some cases more need to cool houses
    in summer (which would suddenly give a more persuasive argument
    for heat pumps which run in reverse during hot weather .. to cool
    houses). The argument about the ground temps being higher seems
    over-simplistic to me. Is it ?
