Grape harvest dates are poor indicators of summer warmth

  • D. J. Keenan
Short Note

Summary

It has recently been claimed that the April–August temperature in France, in any given year, can be estimated from the harvest date of grapes grown there. Based on this claim, it was asserted that 2003 was the warmest year in the last six centuries. Herein, it is shown that the grape-derived temperature estimates are highly unreliable, and thus that the assertion is unfounded.
