OECD analysis finds that about 15 percent of variability in the performance of American students is explained by socio - economic factors; the OECD average is 10 percent.13 Research suggests that if the PISA results of U.S. students are adjusted such that the distribution of low - income students is more similar to other countries with comparable post-industrial economies, both math and reading results would look significantly higher.14 This does not mean the United States should not be concerned about international comparisons of educational achievement, but it suggests that the conclusions drawn from rankings based on national averages are limited and that reality is more nuanced.

This work revealed, as the seven scientists describe it, that «the lowest isotope values (highest temperatures) of the last millennium are seen ~ 1100 - 1300 A.D., during the Medieval Climate Anomaly, and again after ~ 1950 A.D.» In between these two warm intervals, of course, were the colder temperatures of the Little Ice Age, when oscillatory thermal minima occurred at the times of the Dalton, Maunder, Sporer and Wolf solar minima, such that the δ18O proxy record of near - surface water temperature was found to be «robustly and near - synchronously correlated with various proxies of solar variability spanning the last millennium,» with decade - to century - scale temperature variability of 1 to 2 °C magnitude.»
