Why Human Activity Can Make Discerning the Impacts of Climate Change So Difficult

A simplified version of the scientific method goes like this: ask a question, make a hypothesis, test the hypothesis in a controlled experiment, analyze results, draw conclusions. But as a team of scientists showed in a recent study of a New England forest, that approach won’t always yield perfect results—particularly in the natural world—if we [...]
