We are seeing an increase in heavy rain events scattered around the world but in the Eastern US and Southern Ontario and other regions, I've noticed ....now...even in mid-August a very lush look to the vegetation.
In Pennsylvania wilds and around southern Ontario there is a look to the vegetation of growth and "new green" that I usually associate with late spring.
I travel a fair bit outside the urban areas on the mcycle and have for 40 years so I have a sense of seasonal change.
My backyard has seen hilarious growth in the trees so that there is an entire canopy.
Even in Northern Alberta, BC and parts of Alaska where we spent a month, it did not have the appearance of mature summer but rather vegetation that was still in growth phase.
Now some of those areas ( S Alaska and BC are temperate rain forest so it's to be expected ) but prairies and farm land across the middle of Canada just had this uber - green look to them.
Not the darker green of fading summer.
No question it's been wet in the areas we travelled ( except the Yukon which is tinder dry ) and Manitoba was still flooded. ( state of emergency level )
So that may have a role to play but it seems even beyond that.
CO2 levels hit 400 ppm this year......a significant increase over pre-industrial. Is this sufficient to see some acceleration in plant response?
Anyone else noticed......?
Anyone have a link that might shed some historical light on yields ?( tho there are sooo many variables ). :boggled:
