"Impacts of climate change on natural forest productivity-evidence since the the 20th century" by Celine Boisvenue and Steven Running, tells about how climate changes have changed in the last 55 years and are affecting all types of forest. Increasing temperature can increase vapor pressure of air which increases transpiration rates, resulting in adverse effects on dryer sites.  Temperature also controls the a plants metabolism rate which can determine the amount of photosynthesis. The charts in the article show that the ecological response to global climate change is greater at high latitude. The article breaks down the different responses to climate change in tropical, boreal, and temperate forest, some of which have received positive results because there water is not strongly limited.
