SUMMARY:Understanding 20th century surface temperature variability - David
  W J Thompson\, Colorado State University
DTSTART:20080522T131500Z

UID:TALK11767@talks.cam.ac.uk
CONTACT:Dr Glenn Carver
DESCRIPTION:The prevailing view of 20th century temperature variability is
  that\n the Earth warmed from 1910 to 1940\, cooled slightly from 1940 to\
 n 1970\, and warmed markedly from 1970 onward. In this talk I will\n explo
 it a physically-based filtering methodology which provides an\n alternativ
 e interpretation of 20th century global-mean temperature\n variability. Th
 e results clarify the consistency between the century-\n long monotonic ri
 se in greenhouse gases and global-mean temperatures\,\n provide new insigh
 ts into the climatic impact of volcanic eruptions\,\n and highlight a glar
 ing but previously overlooked error in the time\n series of global-mean te
 mperatures.
