Yes but this should impact both places equally, Lower air density will 
derate stoves power as less airmass will be passing through the stove,

My point was that the wood sample will actually change in moisture content 
with changes in humidity, albeit a small amount which I doubt would 
produce a discernible change in combustion.

Exhaled air contains about 4% CO2 and a petrol engine exhaust as much as 
13% IIRC and we know that feeding back CO2 can depress grate temperature 
so if the air is still and a lot of traffic your first thought may be 
possible.
