AOSC Seminar by Dr. Alice Crawford

Chair's Welcome

Welcome to the Department of Atmospheric and Oceanic Science. The Department, part of the Earth Sciences Program that includes the collocated Earth System Science Interdisciplinary Center, offers undergraduate and graduate degrees in atmospheric and oceanic sciences, and climate earth sciences.

The department's research strengths are reinforced by strong collaborations leading to joint research topics with NASA Goddard Space Flight Center, Maryland Departments of the Environment and of Natural Resources, the National Centers for Environmental Prediction of the National Weather Service, the NOAA Satellite and Air Research Laboratories, all of which are located near the campus.

James Carton, Professor and Chairman

Ross Salawitch and team publish “Paris Climate Agreement: Beacon of Hope” illustrating optimistic climate future
Drawing momentum from the historic Paris Climate Treaty Agreement that took place in December 2015, Dr. Ross Salawitch and AOSC colleagues Dr. Tim Canty, Brian Bennett, Walt Tribett and Austin Hope recently published, “Paris Climate Agreement: Beacon of Hope,” a book which analyzes the greenhouse gas (GHG) reductions necessary to limit global warming to 1.5-2 degrees Celsius. “Paris Climate Agreement: Beacon of Hope,” illustrates this rise in global mean surface temperature is attainable as long as intended nationally determined contributions (INDCs) of emissions are adhered to and propagated forward to the year 2060. The authors show that the Paris goals are possible through their development of a global climate model (EM-GC), which concluded GHGs must only follow the Representative Concentration Pathway (RCP)-4.5 for the target warming to occur. This pathway is more optimistic and realistically attainable than what previous global climate models (GCMS) had prescribed countries must follow. The book concluded that current GCMS likely represented climate feedback in a manner that amplified the radiative forcing due to GHGs too strongly. Still, to achieve RCP 4.5 half of the world’s global energy must come from renewable sources by the year 2060. “This will require a large-scale transfer of technology and capital from the developed to the developing world,” said Salawitch.

AOSC Research Featured in the Climate Science Special Report

The attached article, published in the UMD Diamondback, was written by AOSC Undergraduate Greta Easthom.

The report, which is the first part of the Fourth National Climate Assessment, produced every four years by the U.S. Global Change Research Program, was released by the Trump administration. The report features information on "documented changes in surface, atmospheric and oceanic temperatures; melting glaciers; diminishing snow cover
