Could be, and that is of interest, however it proves nothing in relation to 
'global warming' (or what, now that we are apparently in a cooling phase, is 
conveniently renamed 'climate change').

What it may prove is something that is already obvious: that we are 
polluting our planet, (or to choose a less loaded term) altering levels of 
some chemicals in ways that may or may not be significant.  That, I think is 
beyond debate.

The link between C02 and changes in climate, however is more of a stretch. 
Personally, I am quite concerned about heat and light pollution, and their 
local effects.  Interestingly, the idea of replacing energy that has been 
locked up fossil fuel with heat and light and motive energy from wind, water 
and sun would reduce the net heat load from civilization.  That does not 
solve the problem of heat being dumped in water bodies or the atmosphere, 
but it does reduce the heat input.

What this has to do with bees, I am not sure, but I guess, bees being as 
important as they apparently are, we must assume that everything has 
something to do with bees..
