From the article....
In North American forests, invasive vines such as kudzu, oriental bittersweet, English ivy and Japanese honeysuckle often reduce native tree regeneration and survival, although there is no obvious trend as there is in the American tropics. In contrast, two studies of forests in tropical Africa did not detect vine overgrowth.
Looks to me like this isn't a global climate issue, which is what the story wished to insinuate. Something else is afoot.....
they should check out wisteria...........
Well, we made it thru global cooling scare, the global warming craziness, the AGW climate change might be diminishing... so how many $trillions and inalienable rights will the attack of the vines cost us?
