Yeah, possibly, or more likely it's incredibly dangerous making rapid changes to the chaotic but balanced system that we live within. The plants might grow bigger - until a voracious pest migrates into the newly available area and destroys them, or wildfires raging in the newly warmed area burn them to the ground. The current global climate is probably not the optimum for human activities - perhaps that was some time ago, before the extreme weather events that we are ushering in started wreaking havoc. There's no reason to believe that fucking up the planet is somehow leading us towards a better, more optimum situation.
