  3. WHAT PROMPTED ME TO CONCENTRATE ON CO2 ISSUES? • My training as a meteorologist with the Australian Bureau of Meteorology (1961) • My interest in cave exploring – which spurred an interest in carbonate geochemistry. CO2 + meteorology = global warming

  5. CAVE DECORATION

  6. FAVORITE PAPERS The papers I am most proud of are … Wigley, T.M.L. and Brimblecombe, P., 1981: Carbon dioxide, ammonia and the origin of life. Nature291, 213–215. (cited 14 times) Wigley, T.M.L., 1991: A simple inverse carbon cycle model. Global Biogeochemical Cycles5, 373–382. (apparently never cited) Wigley, T.M.L., 1991: Could reducing fossil-fuel emissions cause global warming? Nature349, 503–506. (cited 90 times) The accomplishment I am most proud of is the development of the MAGICC/SCENGEN user-friendly climate model software. This has been downloaded from the CGD web page about 4000 times, and, as such, is one of the most widely used climate models in the world.

  7. A RESULT WITH MANY FACETS This shows that a stringent CO2 reduction policy could, due to the concomitant reduction in SO2 emissions, lead to warming – the yellow curve.

  8. MY MOST INTERESTING CHALLENGE Defending legitimate science against the greenhouse skeptics. On a recent trip to New Zealand I even found their secret base …

  9. THE SKEPTICS BASE

  10. THANKS TO PRESENT FRIENDS Many thanks to you all for your friendship and a host of fascinating and rewarding collaborations
