Question

6) A method of estimating earth temperature based on local precipita on 100s of years of earth at several different constant green house gas level (So co temperature for 100s of years), and compare the correlation predicted precipitation patterns in a region, and observed precipitation patt few year time period. tion is to build models based nstant global of statistical relationships between erns for a region in a The following are p values of correlation of seasonal precipitation variation in northern California vs temperature in degrees C above 1950 base line for the years 2007 to 2012: Temperature rise Pvalue .05 12 .61 15 34 07 .25 15 21 .35 002 .4 13 .45 .2 .5 001 .55 003 .6 0001 75 .07 001 85 15 36 .95 A) Use a False discovery rate of.05 to identify temperature rises in which the local precipitation rate over northern California is reasonably modeled. Calculate the mean and median of these temperatures. B) C) The actual average global temperature rise since 1950 over this time was approximately 0.62 degrees C, how close is this.
