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.

A Town Hall Meeting at Yale with Senator Chris Murphy (September 13th, 2pm)

The Yale Climate and Energy Institute will host a panel discussion on how global warming will affect New England in the 21st century and how the region is preparing for the coming changes. The meeting will take place at the Yale School of Forestry & Environmental Studies, in Burke Auditorium of Kroon Hall, on 195 Prospect Street in New Haven and include short talks by climate and infrastructure experts and a panel discussion with Senator Chris Murphy.

Join us for a discussion of these topics with panelists:

 – Senator Chris Murphy (D, CT)

What Happens in the Arctic Doesn't Stay in the Arctic (and why you should care).

Fran Ulmer is chair of the U.S. Arctic Research Commission, appointed by President Obama in March 2011. In June 2010, President Obama appointed her to the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling. From 2007 to 2011, Ms. Ulmer was Chancellor of the University of Alaska Anchorage (UAA). Before that, she was a Distinguished Visiting Professor of Public Policy and Director of the Institute of Social and Economic Research at UAA. Ms.
