Everyone knows plants need CO2 to grow. So it seems logical that the extra carbon we’re spewing into the atmosphere will make plants grow more, capturing more carbon and mitigating climate change, right? That’s something argued by climate change skeptics and assumed by some scientific models used to predict future changes in the Earth’s vegetation.
But growing evidence suggests that extra CO2 in the atmosphere isn’t making trees grow more. And, in fact, climate change is generating warmer, drier conditions that could make them grow less in many places.
