    The faster trees grow, the younger they die

    As climate change spurs forest tree growth, it also shortens trees’ lives. That results in a quicker release of climate-warming carbon back into the atmosphere.

    Analyze This: Climate change could make food less healthy

    Levels of important nutrients are lower in crops exposed to high levels of carbon dioxide, a greenhouse gas. How high? Try levels expected to be typical 30 years from now.

    Explainer: The fertilizing power of N and P

    Two elements — nitrogen and phosphorus — help plants grow. When the soil doesn’t have them, farmers might add them in the form of fertilizer.

    Trees can make summer ozone levels much worse

    The greenery can release chemicals into the air that react with combustion pollutants to make ozone. And trees release more of those chemicals where it gets really hot, a new study finds.
