Mining the written history of medieval Ireland for connections to human violence and climate change.

Francis Ludlow is a Postdoctoral Fellow with the Yale Climate & Energy Institute, where he works with Prof. Benedict Kiernan of the Department of History and Prof. Michael R. Dove of the School of Forestry & Environmental Studies, on a project entitled Climate as Catalyst in 1,224 Years of Violence and Conflict in Ireland, 425-1649 CE. From 2013-2014 Francis held the position of Carson Fellow at …

Climate Change Impacts Antarctica's Ross Sea

The Ross Sea, Antarctica’s most pristine region, is experiencing anomalously marked increase in sea ice concentration. Future changes in atmospheric temperatures and wind speeds, however, will likely produce a noticeably different environment. Smith et al. examines the effect of projected changes in atmospheric temperatures and winds on aspects of ocean circulation and its implications for primary…

On the Use and Abuse of Climate Sensitivity as a Concept in Paleoclimate. Matt Huber

“Given the nature of the subject we must remind ourselves that it is simply not possible to construct a model…
that can serve as a scaffolding on which….[we] can rely on support at all times….
No matter how versatile the code, the situation will always lead to the consequences
we have already alluded to:….theory conflicts with practice.”

From Clausewitz, (On War, Paret Translation 1989)

Down-scaling Climate Models Without Up-scaling Costs

A recent study published in Global and Planetary Change demonstrates cost-saving opportunities in the otherwise computationally expensive process of high-resolution climate modeling.  General Circulation Models (GCMs, occasionally also referred to as ‘global climate models’) are extremely useful tools used to understand how our climate system works.  The models use mathematical equations to describe the physics of the oceans and atmosphere.  These equations quantify, for example, how hot air tends to rise (the reason hot air balloons fly) and how the wind flows from high-pressure areas to l

The Importance of Model Resolution in Global Change Biology

Biologists increasingly realize that understanding the impact of global change on biological processes requires accounting for fine-grain environmental variability (Potter, Arthur Woods, & Pincebourde, 2013). Similarly, climatologists have found that increasing the resolution of climate models typically produces better simulations of climate and precipitation…

Global Environmental Justice: A Public Political Ecology of the Carbon Economy

Tracey Osborne is Assistant Professor in the School of Geography and Development and Director of the Public Political Ecology Lab at the University of Arizona. Her research investigates the political ecology of environmental markets, particularly carbon markets, and their implications for the lives and livelihoods of forest communities in the Global South. Specifically, she explores the intersection of carbon markets, development, and agrarian change as they relate to forestry-based carbon initiatives in Mexico.

Up in the Sky: Next week's forum on global climate & atmospheric modeling

New insight into the origin of monsoons, the potential use of aerosols to cool the globe, and how different industries uniquely impact atmospheric warming are the contributions of YCEI researchers at an upcoming forum on Global Climate and Atmospheric Modeling, Saturday, September 21, at KGL.  Researchers from Tokyo’s Todai University round out the 5-person forum with talks on the radiative forcing of aerosols in East Asia and a model of 100,000-year glacial-interglacial cycles.  The forum starts at 1 p.m.
