... 1 he Assessment used the Ladled (=enter tor (:ltmate l'red~ct~on and Research (climate Model 2 and outputs from the Canadian Climate Centre Global Climate Models (GC~ to give a range of potential future climates and their effects. He characterized the Canadian Climate Centre model as a "hot model" or a "very warm model".

... The IPCC's report conclusions were generally supported by the NRC report, which along with national academies from 16 other countries basically endorsed IPCC findings. The NRC report agreed with the IPCC report that sea level will continue to rise, rainfall rates will increase in many regions and many semi-arid regions will experience more severe droughts.

... Zweirs showed that modeling extreme events using GCMs can be very difficult and complex, but not impossible. The Canadian Climate Model predicts that rains with an 80-year return period would become midyear events by the end of the 21St century if He climate is forced according to the IPCC IS92a emissions scenario.

... This change in the frequency of high intensity rainfalls has enormous implications for storm drainage design and flash floods, for erosion and erosion control, and other events and their associated controls that are greatly influenced by high rain intensities. According to predictions for maximum temperatures, 20-year return period values would go up some 46° C over most of North America and as much as 10° C in southeast United States.

... For disaster mitigation activities preventive measures through incentives are worth exploring. Using insurance rates as incentives to plan for climate variability and change should be used with prudence, however.

... · There is a need for improved models for climate change projections involving the nature of land cover, the biological aspects of the land, oceans and the geochemical cycles. · The climate analysts indicated that some extreme weather events, such as heavy rainfalls and maximum and mirmoum temperatures, appear to be increasing, as was projected by climate models.
