There has been documentation that there has been approx. 2 week 
extension in the spring and some extension in the fall of 
a "greening" up of the northern latitudes.  I couldn't find the 
article, but if I remember correctly, this finding was the result of 
trying to determine where the "missing" carbon dioxide was (i.e. our 
industrial civilization is putting out X amount of CO2, the ocean 
absorbs Y, and plants can be estimated to absorb Z, and the remaining 
goes into the atomosphere as extra CO2 A.

But X > Y + Z + A

Well it was conclusion that "part" of the CO2 was being absorbed by 
longer seasons in the north.  

I'm sure this affect is not consistent every year or even over all 
areas (particular Minnesota in its ice age  :)

Indeed, for many years they have been quite a plague in warmer zones 
and people used to joke about the earwigs being able to climb walls 
but not the Gatineau Hills...
