Abstract

This report uses the CMIP5 series of climate model simulations to produce country-level uncertainty distributions for use in socioeconomic risk assessments of climate change impacts. It provides appropriate probability distributions, by month, for 169 countries and autonomous-areas on temperature, precipitation, maximum temperature, maximum wind speed, humidity, runoff, soil moisture and evaporation for the historical period (1976-2005), and for decadal time periods to 2100. It also provides historical and future distributions for the Arctic region on ice concentration, ice thickness, age of ice, and ice ridging in 15-degree longitude arc segments from the Arctic Circle to 80 degrees latitude, plus two polar semicircular regions from 80 to 90 degrees latitude. The uncertainty is meant to describe the lack of knowledge rather than imprecision in the physical simulation because the emphasis is on unfalsified risk and its use to determine potential socioeconomic impacts. The full report is contained in 27 volumes.

Z.1. INTRODUCTION

This volume contains one of the appendices noted in Volume 1. Each appendix details the data for a single variable. The next section describes the basic information needed to interpret the data and then provides the actual data. The data for each variable are contained in separate report volumes as noted in the table below. The report and all appendices are publicly available1 and the data in EXCEL format are available upon request.2

Z.2. ARCTIC SEA ICE RIDGING RATE

This appendix contains the uncertainty distribution information on the Arctic Sea Ice Ridging Rate for the forecast time period (CMIP5 output variable name: ridgice). The parametrization is for the Gumbel distribution. Note that the parameters enable the calculation of the mean, median, and mode values, as well as of the exceedance-probability values. See the main text (Volume 1) for a further description of the variable, and on finding or using the appropriate data. The raw values from the models have been converted to have dimensions of (m2/da)/m2. So few models reported this variable that the parametrizations lack statistical validity, and as such, the data below are only useful in illustrating potential climate-impact issues. When the data notes NaN (Not a Number) this implies the data lack adequate variation to calculate a value. Using 0.0 for the value is appropriate.

The pages that follow alphabetically cover each country or autonomous-area, with the distribution parameters for a time period, for a specific month. The table shows the centroid (average) year for the time period, should a user, for simulation purposes only, want to create linearly interpolated values between years. Interpolation requires both historical and forecast data for the years through 2015. The data maintain consistency across the historical and forecast time period to allow such interpolations. Although the change between years are closely approximated through linear interpolation, no claim is made here for the legitimacy of this usage for all purposes.

For forecast data, the values correspond to the average over the (typically) decadal period noted in Columns 6 and 7 of the data table below. For historical data, the values correspond to the average over the 30 year, 1976 to 2005, “historical period” segment from the CMIP5 model runs. Thirty years is typically the averaging time period used to describe the “normal” condition. Because, for example, conventional macroeconomic models do not generally include climate impacts, their results implicitly include the historical normal. Because climatic changes are relatively gradual during the historical period and the first decade of the forecast period, it is generally acceptable, for continuous-simulation purposes, to consider the average as representing a 1990 referent year.

The models used to calculate the distribution are compared in Chapter 2 of Volume 1. Essential information on the functional aspects of the probability distribution are shown on the next page.

The data columns of all the tables first include the country, then the type of distribution, the two parameters that define the distribution (as noted in the Chapter 5 of Volume 1), the standard error on the CDF estimate (the second order uncertainty), the beginning year of the data used to calculate the distribution, the last year of data used to calculate the distribution, the mid-year centroid, the month associated with the uncertainty distribution, and the short, CMIP5 variable name (noted in Table 3 of Volume 1).

As noted in the main text (Volume 1), the most legitimate use of the data is the comparison of a future sampled value to the historical mean or sampled value. The ratio of the forecasted and historical values minus 1 denotes the percentage change from historical values. This value most likely corresponds to the information needed to perform the impact analysis. Alternatively, but somewhat less meaningful, the difference between the numeric value of the forecast and historic values may be required for the impact analysis, for example, those associated with food production or water flow. For an example risk assessment see Backus et al. 2010.4
