Many factors in this. Heat islands from urbanization in Kyoto, different species bred for earlier blooming, etc.

If only we had a plausible hypothesis that covered not only early blossoms in Kyoto, but hundreds of other observations in climate all in the direction of a rise in global temperature, be it in urbanized areas or in remote regions like Antarctica or glaciars... Damn scientist, they might be sleeping or something.

Is the "etc" here "because of human greenhouse emissions, the earth is rapidly warming"?

If these events where random noise then they would distribute in both sides of the climate models; We don’t observe that. Events only seem to match or be worse than expectations.

> The signal is local to one species

lo heat, why doth thou radiate? from your islands; blooming species differently...
