    The Double-Edged Sword of Geoengineering

    Shooting sulfur particles into the stratosphere to reflect the sun? Dumping iron into the ocean to boost the absorption of carbon dioxide? Could these far-fetched and dangerous-sounding schemes—geoengineering—help avert potentially catastrophic effects of climate change, or would they exacerbate conditions on our ever warming planet?

    Dead Plants Strengthen Beliefs in Global Warming

    Subtle stimuli in the environment exert a strong influence on the way we think about global warming. The notion that surrounding objects unconsciously influence our thoughts and behavior is of interest to individuals who are interested in developing strategies to promote sustainable behavior.

    Save those Acorns for the Apocalypse

    As biodiversity takes a hit from climate change, forward thinking groups store seed samples in gene banks. The idea: if an entire species is wiped out, scientists can repopulate from the samples. Hello, plant versions of Adam and Eve.
