I can't believe I have been floundering around for so long before finally figuring out that ozone is the main culprit killing vegetation. Plenty of information pops up instantly just by googling "ozone" and "plant". (And thanks to Daniel for putting it front and center for me.) Having said that, it doesn't explain why the authors of these studies aren't shrieking from the rooftops that we are all going to starve to death in very short order if we don't do something DRASTIC to curb greenhouse gas emissions, which, as we all know, humans are producing like there's no tomorrow...oh, wait...
Since it seems these scientists obviously know enough about it to be thoroughly and justifiably alarmed I am going to write to them and ask them why they aren't sounding the alarm.
The following links amply document the method by which tropospheric ozone is created, and its role in harming plants which has an amplifying effect on global warming. I do not believe this has been taken into consideration by models for projecting future changes in climate; nor have I found any more recent studies that document the exponentially increasing damage that is plainly visible.
These pictures - from the US Government! - look exactly like mine:
So rather than uploading yet more examples of dying trees, instead for fun I am going to steal daughter Sophie's pictures from her trip out West!
