Ecosystem Resilience: Navigating Our Tenuous Connection to Nature

How can humans thrive within a natural world that holds the ingredients necessary for our survival, but at the same time is threatened by our domination of that world? Sustainability of the goods and services provided by Earth’s ecosystems is dependent on mechanisms of resilience that include maintenance of biotic diversity and avoidance of climatically-controlled ‘tipping points’. This lecture will explore how recent trends in land use and anthropogenic climate warming have exposed vulnerabilities in the mechanisms of ecosystem resilience, and revealed the potential for surprising shifts in the productivity and persistence of ecosystems. Recognition of the interactions between anthropogenic climate forcing and natural climate cycles, and breakthroughs in the fields of genomics and ecosystem modeling, provide opportunities for management of ecosystem resilience. With adequate foresight and focus, humans can learn to navigate toward a more sustainable future.

Are We There Yet? Landing Site Selection on Mars

NASA-funded scientists and engineers have been evaluating landing sites using modern methods for 30 years, and have developed strategies and techniques that have resulted in six successful landed missions on Mars. In this talk, I will discuss the history of selecting landing sites on Mars and the current state-of-the art methods for characterizing the physical surface on Mars in terms of 1) slope and topography analyses and 2) deriving and interpreting surface properties. I will then discuss where we are as a community in terms of our ability to determine safe landing sites for future missions and potentially landing humans on Mars.

Climate Change and Human Health: Impacts and Pathways to Resilience
Climate change induced impacts on human health are myriad; they range from direct effects, such as heat related mortality during extreme heat events, to indirect effects on infectious disease transmission systems. Predicting the degree of impact climate change will have on a specific health outcome becomes more difficult as the pathways become more indirect. One such example is determining the potential risk of dengue emergence in the U.S.-Mexico border region where Ae. aegypti mosquito populations that transmit the virus are well-established. A suitable natural environment is necessary but not sufficient for virus transmission. Social, economic, and behavioral factors can all enhance or reduce risk. While these factors make predictions difficult, they also suggest a level of control that we as a society have to reduce our risk of negative health outcomes linked to a changing climate. Both top-down and bottom-up actions must be taken now to mitigate current and future health threats.

Carbon Sequestration: Can We Afford It?

Climate change as a result of carbon dioxide emissions from industry and power plants (especially coal-fired plants) is a world wide concern. Global strategies are required such as those proposed by the International Energy Association, which states that a minimum of 1/6th of CO2 future emissions must be captured and stored by 2050 to limit rises in average global temperature. Although there are many methods for capturing carbon, the primary barriers are testing them at a large scale, building an infrastructure to support them, and cost. These technologies include everything from injecting CO2 in the ground to recover oil to pumping it deep into the ocean to storing it in deep saline reservoirs to producing soil amendments. In addition to reviewing these technologies, this lecture will discuss methods for reducing carbon emissions by using more alternative energy as well as CO2 uptake by microalgae to produce food and fuel.
