Grassland paper chosen as cover in PNAS

Cover image: Pictured is grassland at the Jasper Ridge Biological Preserve in California. Over 17 years, Kai Zhu et al. subjected this grassland to changes in temperature, precipitation, carbon dioxide, and nitrogen, both individually and in combination, to determine how simultaneous changes in multiple global environmental factors would affect primary production. Primary production was a ridge-shaped function of temperature and precipitation, with peak production increasing with added nitrogen and shifting to lower temperatures with added [...]

Figuring the odds of Earth’s global hot streak

Is global change real? How about this year's temperature record? I helped to calculate the odds--really low, indeed! GO FIGURE: Figuring the odds of Earth's global hot streak The global heat streak of the 21st century can be explained with statistics that defy astronomical odds. First, the National Oceanic Atmospheric Administration calculates global average temperature going back to 1880. That's 135 years. So if no other forces were in play and temperatures last year were totally [...]
