Recent and substantial increases in heat and heat wave mortality and morbidity impel society to brace for heat events of even greater severity and duration. Unfortunately, research on the relationship between future heat increases and its health impacts generally overlooks how choice of exposure metric (mean, minimum & maximum temperature) effects downstream projections. Additionally, regional growth management plans are generally not incorporated into climate impact models. Both considerations are important for…

A new metric called “suitable plant growing days” helps address an argument often made by climate skeptics: since carbon dioxide promotes plant growth – especially at middle and high latitudes – anthropogenic carbon dioxide emissions will increase agricultural yields and carbon sequestration across the world’s forests.  The relationship is not so simple, however. Other factors influenced by climate change (e.g., temperature, water availability, solar radiation) strongly affect plant growth and survival as well. The interactions…

Whether or not the emerging El Niño ends California’s terrible drought is uncertain, says a noted Yale meteorologist, but its likely impact on average global temperature should silence arguments about a hiatus…

Professor Ron Smith reflects on what the emerging El Niño portends for the “hiatus” discussion, and explains how the weather phenomenon’s enormous scale exerts enough force on the Northern Hemisphere to slow the Earth’s rotation.
