Not what I'd call a "dire effect."
Your grass may be staying green longer and that may be due to some global climate change or to some regional climate change.
I recall when hurricanes took down most of the large, old willow trees in my then area of NYC. That was in the 1950s and 1960s. Hasn't recurred. And that obviously hadn't occurred for some time prior to that period for the fact of the trees being old. Change happens.
A hurricane is a one-time "change". The gradual global warming isn't. People can pretend that it isn't happening - but that won't change the reality.
The only difference I have with the Global Warming Alarmists is the CAUSE of global warming - not the reality of it. I don't think mankind is causing it, I think it is a natural cycle of the sun.
To ignore the reality of it is nothing more than burying ones head in the sand and pretending that it really isn't happening.
But it is.
