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.

The Hockey Stick and the Climate Wars: Dispatches From The Front Lines

A central figure in the controversy over human-caused climate change has been “The Hockey Stick,” a simple, easy-to-understand graph my colleagues and I constructed to depict changes in Earth’s temperature back to 1000 AD. The graph was featured in the high-profile “Summary for Policy Makers” of the 2001 report of the Intergovernmental Panel on Climate Change (IPCC), and it quickly became an icon in the debate over human-caused (“anthropogenic”) climate change.

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.

New York City's Special Initiative for Rebuilding and Resilience: Strengths and Limitations of Climate Model-Based Approaches

Radley Horton from Columbia University Earth Institute will speak on climate projections for New York City.  The $20 billion Special Initiative for Rebuilding and Resiliency (SIRR) Plan for New York is grounded upon climate risk information provided by the New York City Panel on Climate Change (NPCC). This expert panel, tasked with advising the City on climate-related issues, completed a ‘rapid response’ climate assessment with updated climate projections.

Advances in Global Climate and Atmospheric Modeling: Perspectives from Yale and Todai

Researchers from Tokyo’s Todai University and Yale climate scientists made up a 5-person forum that included talks on a variety of climate science topics Friday, September 21, at Kroon Hall.  Featured talks included:

Asia: Observations and modeling - Yutaka Kondo (University of Tokyo)

Aerosol effects on ice clouds: Climate forcing and potential for geoengineering

Trude Storelvmo (Yale University)

Robust direct effect of carbon dioxide on tropical circulation and regional precipitation

Global warming simulations suggest that wet regions (where precipitation exceeds evaporation) will become wetter and dry regions drier by the end of the 21st century (e.g., Held and Soden 2006), with larger contrasts expected between dry and wet seasons (Chou et al., 2013). This ‘rich-get-richer’ behavior is consistent with a large increase in the moisture content of atmosphere, leading to enhanced horizontal moisture fluxes across regions.
