This analysis
makes clear that large
differences in the performance of high - SES students and low - SES students in the same schools do exist; that these apparent gaps are not
simply reflective of gaps in preparation; and that while the variation across school districts is
substantial, the variation within school districts may be even larger (at least among the largest districts in Florida).
However, for such an ambitious target as 1.5 C, 0.3 C can
make a
substantial difference when calculating how much remaining CO2 we can still emit without pushing us over 1.5 C of warming when the remaining budget is calculated by
simply subtracting off estimates of cumulative emissions to date from the ESM - based budgets for 1.5 C relative to preindustrial (i.e. the horizontal
difference between the cross and the vertical dashed black line in the figure above).
