Spring Arrives Earlier, Fall Comes Later 0312
From IPCC, 2007. Many-species studies found (averages of range endpoints used) 0.8, 1.6, 4.5, 2.5, 2.85, 4.4, 3.1, 3.15, 6.3, and 0.45 days per decade earlier blooms or arrivals. Grand average of these is 3.0 days per decade earlier.
Flowering Plants Bloom Earlier with Warming 0410 - Average is about 3.5 days/decade earlier.
