wing season indicated by the data may not be a good thing.

“Farmers may tend to look at this and say that it’s good, because they will get an earlier yield. But earlier bloom dates make these species more susceptible to damage from frost,” he said, “and analysis of data on apple yields indicates that warmer temperatures from January 1 to bud break correlated with lower yields, not higher.”

Wolfe also reported that the magnitude of the impact of earlier bloom dates on woody perennials in the Northeast “is similar to that reported for bloom of other plant species, and for bird and insect spring migration arrivals, by researchers in other parts of the U.S. and Europe.” He said findings are also “qualitatively in agreement with reports of earlier spring ‘green wave’ advancement in the northern hemisphere based on satellite imagery of vegetative cover,” both observations supporting the findings.

The remarkable thing about the findings, according to Wake, is the consistency. “Despite the fact that this evidence comes from a wide range of environments – the atmosphere, the biosphere, the oceans, and snow and ice – the remarkably consistent signal of a warming trend across the region cannot and should not be ignored. We now have our canary in the coal mine.”

Markham agrees. “For those who are still asking for scientific evidence supporting the notion that we are already seeing the kinds of effects scientists have been warning us we’d see from global warmig, here it is.”
