[nafex] Re: Climate zone
Hélène
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...
