Emeritus College Seminar with Dr. John Meriwether (Part 2)
- February 25, 2020 (Tuesday) 10:00am – 11:30am, Seminar: Climate Change (Part 2) with Dr. John Meriwether, Professor Emeritus of Physics and Astronomy, For most of us throughout our lives the din of climate change voices has been ever present but steadily becoming louder as the years pass. The physics underlying the explanation of climate change (I.e., global warming) became firmly established in the late 60s and model formulations came shortly thereafter that could be used to compare with observations. Such models when applied to the expected continuation of greenhouse gas content increasing for CO2 from perhaps 275 parts per million at the beginning of the Industrial Revolution (1760) to the present 420 parts per million predict an averaged increase of the global temperature ranging from 2 to 5 degrees Kelvin to take place between now and 2100. Needless to say, such an increase would have major consequences for our world. This second seminar will focus on the expected consequences (sea rise, spreading of wild fires, flooding of cities, increase number of violent hurricanes) as well as consideration of the question as to possible avenues of human responses designed to reduce the rate of greenhouse gas emissions. Possible carbon capture and sequestration scenarios also . To sum up, it is not altogether hopeless that humanity would be able to address this problem effectively but time is drawing short for any significant action to take place. Attendance at the previous seminar not required.
