Seeing the Forest AND the Trees: Predicting Forest Responses to Contrasting Climate Change Influences

By Jacqueline Wen As the effects of climate change continue to escalate, their impacts seem especially noticeable and imminent for humans and other animals. But what about for forests and trees? In a study published in the Proceedings of the National Academy of Sciences (PNAS), Anna Trugman, an assistant professor in UCSB’s Department of Geography,

Maximum CO2 diffusion inside leaves is limited by the scaling of cell size and genome size

By Guillaume Théroux-Rancourt et al. Abstract Maintaining high rates of photosynthesis in leaves requires efficient movement of CO2 from the atmosphere to the chloroplasts inside the leaf where it is converted into sugar. Throughout the evolution of vascular plants, CO2 diffusion across the leaf surface was maximized by reducing the sizes of the guard cells

Should We Trust the Climate Models? Part 3 of 3

By Robert P. Murphy In my first article of this 3-part series on the reliability of the climate models used to guide policy debates, I developed a coin-flipping analogy to make sure the reader understood the concept of a “95% confidence spread.” Then I showed that even using the charts presented by the climate scientists

Scientists: Rising CO2 REDUCES Fires…Australian (Global) Fires Were More Common In Colder (Pre-1950s) Climates

By Kenneth Richard The current furor about an alleged connection between climate change, CO2 emissions, and Australian fires finds no support in the scientific literature. According to scientists, rising CO2 concentrations reduce fire ignition and burned area. Further, both global-scale and Australian fires were far more pervasive during the colder Little Ice Age. Here’s what
