SUMMARY:Blanchard Lecture: Physics of Climate and Atmospheric Carbon D
 ioxide Reduction (CDR)\, Physics Department Colloquium\, Washington Ta
 ylor\, MIT
DESCRIPTION:Human activity\, particularly the combustion of fossil fue
 ls to provide energy\, has led to a continued and well-measured increa
 se in levels of atmospheric carbon dioxide over the last century\, wit
 h increasing effects in recent decades.  Many approaches have been pro
 posed for reducing atmospheric carbon dioxide levels\, including chemi
 cal direct air capture (DAC)\, ocean alkalinity enhancement (OAE)\, en
 hanced rock weathering (ERW)\, and biology-based approaches.  Even wit
 h rapid emissions reductions\,  atmospheric carbon dioxide reduction (
 CDR) may be desirable to avoid excessive changes in Earth's surface te
 mperature and climate.  Fundamental physical constraints\, however\, i
 ndicate that such efforts will require extensive energy and/or materia
 l inputs.  This colloquium addresses these considerations from a physi
 cal science perspective.
