Dan Cziczo will speak about his work as an atmospheric scientist interested in the interrelationship of particulate matter and cloud formation. His research utilizes laboratory and field studies to elucidate how small particles interact with water vapor to form droplets and ice crystals which are important players in the Earth’s climate system. Experiments include using small cloud chambers in the laboratory to mimic atmospheric conditions that lead to cloud formation and observing clouds in situ from remote mountaintop sites or through the use of research aircraft.
Nadine Unger of Yale’s presentation on “Land Use Impacts on Chemistry-Climate Interactions” (Nadine Unger, Yale) is one of five talks from the symposium that you can still enjoy here.
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:
Subpolar ocean gyres (large systems of rotating ocean currents) in the Southern Hemisphere are found poleward of the Antarctic Circumpolar Current near the Weddell and Ross Sea. They play a key role in the global energy and water budgets. These gyres are crucial for the transport of heat around the planet, as well as the distribution of nutrients and marine species. Thus, the subpolar gyres are important in the mixing and transformation of water masses.
Venkatachalam Ramaswamy, Director, Geophysical Fluids Laboratory, Princeton University, delivers a lecture entitled, “Understanding Trends and Extremes in Climate”.
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.
