We found that warmer temperatures and headwinds on the day of the race slow winning times. However, 1.6\u00b0C warming in annual temperatures in Boston between 1933 and 2004 did not consistently slow winning times because of high variability in temperatures on race day. Starting times for the race changed to earlier in the day beginning in 2006, making it difficult to anticipate effects of future warming on winning times.<\/em><\/p><\/blockquote>\n<p>1,6 \u00b0C in 70 anni son tanti! <span style=\"font-size: 13px; line-height: 19px;\">Anticipare l&#8217;effetto \u00e8 difficile, ma gli autori non si scoraggiano:<\/span><\/p>\n<blockquote><p><em>However, our models indicate that if race starting times had not changed and average race day temperatures had warmed by 0.058\u00b0C\/yr, a high-end estimate, we would have had a 95% chance of detecting a consistent slowing of winning marathon times by 2100.
