Prof. Frank McDermott (UCD) will talk on Chemical Weathering as a Strategy for the Large-Scale Capture and Storage of Atmospheric CO2.
Chemical weathering acts as an important, but imperfect, thermostat that
has maintained Earth’s surface temperature within a broad range over much of
geological time. On human timescales, however, this natural thermostat is far too
sluggish to remove the ~35 billion tonnes of CO2 that humans now inject into the
atmosphere every year. The question explored in this talk is whether large-scale
engineered, enhanced chemical weathering could and should be used to remove
gigatonne quantities of CO2 annually from the atmosphere. This question is
increasingly important because it is now recognized that active removal of
atmospheric CO2, in tandem with drastic reductions in emissions, may be essential
to achieve “net-zero” by 2050, a critical requirement to limit global warming to less
than 2 degrees centigrade.
Frank McDermott – Biography
Professor Frank McDermott is currently Head of Geology at
University College Dublin and has been lecturing at the
department since 1996. Frank is a geochemist with broad
interests in aqueous and low-temperature geochemistry, mineral
weathering, isotope geology and U-series dating methods,
palaeoclimatology, atmospheric processes and energy
meteorology. His PhD was on “Granite Petrogenesis and crustal
evolution studies in the Pan-African Damara belt, Namibia” which
he obtained form Open University and subsequently became a
researcher for them also. Prior to his graduate study, Frank
worked in the Mineral Exploration. Frank is also currently an
elected member of the Royal Irish Academy (MRIA and Director
of the National Centre for Isotope Geochemistry (NCIG).
