The Thursday talk – first of two in Professor Bill Ruddiman’s visit to Yale – is called “Depopulation and greenhouse-gas drops”. It summarizes evidence for drops in CO2 and CH4 concentrations during historical time prior to the industrial era. Then it reviews two possible causes: natural climate changes, and depopulation events that reduced anthropogenic gas emissions. For the largest CO2 decrease (between 1525-1610), natural causes were not the major factor. The main cause was the huge depopulation of the Americas because of disease brought in by Europeans.
Resiliency is the theme of Pace University’s upcoming 15th annual land use conference. Defined as “ how systems and settlements stand up to shock from the outside…”1, resiliency is an appropriate organizational concept for a panel discussion on how communities might respond to the potentially shocking discovery of rich stores of gas shale beneath their land.
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…
Since 1993, Pace University’s Land Use Law Center has fostered development of sustainable communities by promoting innovative land use strategies and techniques for dispute resolution. This year’s 13th annual Land Use and Sustainable Development Conference includes discussions involving local control of what many experts see as the inevitable development of New York State’s gas shale resources.
Rit Aggarwala is the former director of long-term planning and sustainability for New York City and currently special advisor to Michael Bloomberg in his role as chair of the C40 Cities Climate Leadership Group.
Steven Stoll of Fordham University studies the history of agrarian society in the United States because he’s found that “agriculture offers the ideal vantage from which to observe the intersection of ideas and practices, economies and landscapes.”
His presentation was videotaped and is presented below:
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.
How will global warming affect New England in the 21st century and how is the region preparing for the coming changes? On September 13th Yale Climate & Energy Institute hosted a town hall meeting on these questions, featuring short talks by climate and infrastructure experts and a panel discussion with Senator Chris Murphy (D, CT).
Respiration by plants and microorganisms is primarily responsible for mediating carbon exchanges between the biosphere and atmosphere. Climate warming has the potential to influence the activity of these organisms, altering the exchanges between carbon pools. Traditionally, the respiratory release of CO2 into the atmosphere is thought to be more temperature-sensitive than photosynthesis (carbon fixation), generating a positive climate-ecosystem carbon feedback with the potential to accelerate climate warming by up to 1.4 times.
