Climate Change Impacts

National Building Codes and Climate Change Considerations

Placebo-controlled analyses were conducted using repeated measures analyses with bonferroni corrections for multiple com The Building codes are starting to consider how to include climate change effects in the engineering design and analysis of structures such as towers. For example the S37 is now suggesting that Engineers should keep current with the climate change literature in order to factor in the results of climate change models into their work.

For me nothing ever changed, it is all still the same. Environment Canada has set up a climate-scenarios web site which provides the results of various scenario and model runs for use by professionals in the Engineering Field. Since the government is not able to predict which of the CO2 scenarios is most likely to materialize, it will be hard for the Engineer to determine the change that he should build into the analysis.

ICE Support for Climate Change Decision Making In producing a site specific assessment for wind and ice we currently provide a 95% confidence interval on the return period winds and ice as determined from the local data. This varies by site due to the variance inherent in the data obtained at the nearest observing site. We are preparing an additional uncertainty measure due to climate change impacts based on the model projections for the location of the site under consideration.

ve sleep parameters were measured using polysomnography with four nights of recordings (two weeks apart). This uncertainty estimate will be provided to the user to be used in conjunction with the currently provided confidence interval. As the climate change scenarios are adjusted over time due to new information on green house gas concentrations and changes to the models themselves, it is planned to periodically update the uncertainty bracket derived from climate change parameters.
